Blast Pipe February 2015 Notice of Meetings Hutt Valley MES Meeting on the first Wednesday, 3 February 2015 at the clubrooms, Petone at 7-45pm. Holiday Update free for all ! There will be the normal session of ‘Bits & Pieces’ Don’t miss Waitangi Weekend (see below) Hutt Valley MES Committee On the third Tuesday, 17 February at 7-30pm Maidstone MES The next meeting will be on Thursday 12 February at 7.30pm Maidstone Park Upper Hutt HVMES - Waitangi Weekend Friday 6 Feb - Sunday 8 Feb. It is planned to follow the example of previous years, when a long weekend results, and run from 10am to 4pm over the three days involved and visiting members and locos will be welcome. With the clubroom repairs still in progress the display of models, working and otherwise, will not be as extensive as in the past and will probably be situated outside under the verandah. Catering will be continuous tea and coffee with a light lunch. There will be a meal after the run on the Saturday evening. It is anticipated that there will be someone sleeping over to provide some security over the time. No doubt there will be some fine tuning of arrangements at the usual monthly meeting the previous Wednesday so make that a date too. From the — HUTT VALLEY MODEL ENGINEERING ! ! ! !

Hutt Valley MES Notes - Editor At our December meeting, which seems so long ago now, we welcomed three visitors and our new member, Paul Barnes. It was good to have 22 present for the last meeting of 2014. Toby Wilkinson had a completed Quorn tool grinder on the table and he showed false modesty by pointing out some of its faults and things he wants to improve already. He commented that he used White Knight epoxy enamel and it looked great. All told it was a triumph and he was pleased to have it ‘completed’ and working. Congratulations Toby. Franz Schleicher had a lashed up folio clock he is working on using meccano, small gears, chain, and material salvaged from old machines and gear. It was a fairly early form of clock design with only an hour hand and named after the folio which is the horizontal bar which oscillates back and forth through an angle of about 60 degrees controlling David Turner had his 3” Case belted up to the sawmill on 19 January, Wellington Anniversary Day. We featured this in the December Blast Pipe but he has since doubled the length of the bench.! ! ! ! Photo - D Turner. *2* the escapement. It will be interesting to see how the ‘Franz’ model will develop. Claude reported on the work done around the site removing growth from close to the clubhouse to facilitate painting. The creeper over the tunnel was not meant to come off but it was the victim of the strong wind one day and most of it was peeled off. Claude had to take it to the tip too. While on the demolishing topic he asked if we were aware of the State Theatre being demolished in Jackson Street Petone. A discussion on the old movie houses of the suburb ensued and we were then shown a photo of the exposed roof trusses in the course of removal. Murray McKenzie then got going on his 3D computer design by explaining the philosophy of getting the design right by checking that it worked through the computer programme rather than the evolution system used by creating a working machine, Mark 1, and proceeding through several improved iterations to the final model. He voiced his trepidation at demonstrating in front of a knowledgable group from his position as a relative beginner in the field, but he had nothing to fear as we all had plenty to learn. The programme he demonstrated with was AutoDesk Inventor Pro 2011. (Several years ago we had Peter Gibbs give us our first taste of 3D in a similarly very expensive programme, “Solid Works”) Murray demonstrated the procedure for design of a simple horizontal steam engine showing the ability to rotate the ‘solid’ design and view from any angle and then to operate the moving parts to ensure clearances etc. Even with his experience he struck one or two things that were beyond his knowledge so a simplified approach was used. The learning curve is fairly steep and one needs to be keen to put in the time and effort needed. Thanks to Murray for giving us a glimpse into the way it is now done.

At the Track As is usual we have found that we have not been rushed off our feet over the hot summer days but we still cater for many of our regulars along with a fair number of visitors to the area. This gives time to enjoy the company, and to play on our trains. The income all helps in the maintenance of our facility. The average number of equivalent rides over 7 recent run days is close to 77 and a couple of those days were pretty unpleasant at our site. Thanks to all those who helped in the running. On Sunday 25 Jan. I had the first drive of #2970 for a while and was relieved to find the hand brake working properly again thanks to Gavin’s attention to the ratchet. This was done back in November so sorry for the belated appreciation. David Turner has been operating his Case on a couple of occasions and at the last one on 19 Jan. he Murray McKenzie supplied these computer generated pictures of the designed oscillating engine and the cylinder component with mounting holes ports etc. The computer can show this in motion too. *3* tried out the modified saw mill with a longer bed, allowing him to cut a ‘log’ of twice the length. This takes about thirty minutes so he is not spending all his time resetting the timber on the bench. Bogie & Track Problems After a few derailments of EC3 in a lightly loaded condition several investigations have taken place. Mounting modifications are to be made to reduce the tendency to lift the bogie sideframe, and the associated wheels on the lightly loaded bogie, when even slight rocking of the load occurs. Unfortunately on one of the trial runs carried out on 25 Jan, to demonstrate this fact, the derailment resulted in the fracture of the DNC cast aluminium bogie sideframe as shown in the photo. It all happened at slow speed. The extra stress on the bogie occurred when a brakeblock on the derailed bogie fouled a track tie down bolt that stands fairly high. This pushed the wheel back causing the fracture. John Antliff reports - “So it has been agreed that the offending track tie downs close to the running rails of the track --- will be removed and the bottom corners of the brake blocks will be flattened off on all our DNC bogies.” Ticket Nippers Missing A while back we put into service two new ticket nippers to replace the old ones which were worn to the extent they only bent the paper in the hole rather than punching cleanly. Only one of these is now available in the ticket office drawer. If you have any knowledge of the whereabouts of the other new one please let us know. We like to make clean holes. While in ‘missing’ mode we draw attention to the presence of ‘Honesty’ on the title of the cash container on our surplus table. If you are owing as a user, or borrower, please fulfil your duty as an honest member. Maidstone MES Notes - Bob Begbie Greetings and best wishes to our members, to members at HVMES, at Maidstone UK and to our readers. We hope you all enjoyed the holiday break. We had good weather in our area and enjoyed the special event that was undertaken for the Tiny Tunes Children’s group. We also enjoyed our club barbecue evening. There was a good turnout for that. All participants left well fed. Track running on that evening was restricted to club members only and trains were run around our track in both directions. Trains were parked at the passing loops on our back straight and allowed to move out of those loops only after exchange of tablets authorising access to the section of railway on which their journey was to be completed. Proper railway procedures were observed. The photo above shows the top bogie centre on the wagon underframe. The bolt on the bogie bolster acts as the king pin and this mounting is to be given more fexibility. Note the bogie has been turned as the brake cylinder should be adjacent to the vacuum brake hose just visible in the step in the underframe. Left - The bottom of this brake block showed it hit the track tiedown bolt resulting in the frame fracture. ! Photos- Anderson We managed successful and pleasing scheduled track runs over other parts of the Christmas, New Year period. Sunday 4th January saw Brian Hawkes 5” gauge Railmotor Steam locomotive, Katie, run for the first time since 1997. Brian was pleased with its performance. He has added a water tank behind the drive car with an electric pump feeding to the locomotive water tender. That has greatly increased the working range of the engine. The club locomotive, Tr107 has also been in Brian’s workshop having the rear springs shimmed to raise the rear end of the engine and having a hole cut in the chassis to allow better access to change engine oil. It is also being measured with the object of having a front NZR pattern coupling made and installed. On Sunday, 18th January we had all the boxes ticked for a good running day; good weather, a good supply of motive power and passenger trollies and operating manpower. The only thing we were short of was passengers. For some reason there were not a lot of people in the park. I expect there would have been some competition from the annual “Wings over Wairarapa” air show in Masterton. That was a pity. We had the following visiting drivers, with steam locomotives, all willing to do a job, but there was not a lot of work for them. Blast Pip February 2015 *4* Brian Hawke is shown with his Railmotor Katie that has been returned to service. It was built by Phil Davis in 1994 as noted from the name plate. ! Photos - B. Hawke ➡ Dave Brownlow with his 7½” G Fairlie, S216 ready to run on the ground level track. ➡ John Antliff with his 7½” G 4-6-0 John Henry to run G/Level ➡ Bill Phillips with his 5”G 4-6-0 Springbok, Gazelle to run on our elevated track. Those visitors were certainly most welcome. We thank them for their offers of assistance. We are sorry there was not a bit more work available. Peter Anderson of HVMES visited, this time wearing his competent person’s hat, rather than as newsletter editor. Peter reviewed our progress in making ready for a formal inspection of our facility, the necessary prerequisite to enable our application for registration of our activity. We thank Peter for his help in that direction. We were able to show him anti-tipping guides we are making to ensure stability of passenger trollies on our elevated track when running on steel I beams that are used in three places to support that track. We have been helped publicise our operations for 2015 by the Upper Hutt City Council who publish a calendar which they distribute to all homes in Upper Hutt City. For 2015 they have included a note of our planned running days and running times on the calendar page for each month. That will be a great help to us. We will have to make sure we get our run dates and times to council in time for inclusion in future calendars. Notice of our scheduled Sunday afternoon public running sessions is also being published in council sponsored activities notices in our local weekly community newspaper, the “Upper Hutt Leader”. We are sure those notices will help spread news of our activity and thank council for publishing those run dates. We really appreciate that assistance. We have just received from the Maidstone Model Engineering Society, UK, their winter 2014/15 newsletter, and are greatly impressed by the note of how that club maintains contact with two older people. One lady, Elsie Gurr, just turned 99, still regularly visits the club, with assistance of a member and her carer. Another contact, Reg Holdstock, now in a nursing home, and not long past his 102nd birthday is visited and kept in touch by club members. We will be grateful if MMES, UK will pass our regards and best wishes to Ms Gurr and Mr Holdstock. I will be very pleased if I am visited by members from MMES, NZ, when I am 102. Unfortunately, by that time, visitors will probably need to be able to cope with an uncomfortably warm environment! Track running sessions planned before issue of the next newsletter are:Sunday afternoons1.0 to 4.30pm each day, weather permitting. **** Sunday 1st February Team 1 **** Sunday 15th February, Team 2 Our club meeting for February will be held from 7.30pm on Thursday 12 Feb in our meeting room in the Maidstone Park amenities building. We will try to bring members up to date with our preparations for inspection for registration of our operations. With a little luck Ross may have another of his woodwork puzzles and may even be persuaded to divulge the secrets of some of the earlier tricks he has shown. We shall look forward to seeing you there. Kapiti Summer ‘Blowdown’. The newsletter published in December from Kapiti shows plenty of activity planned over the summer including a Charity run, but there is no mention of their usual open weekend at this time of the year. Track maintenance has put it on hold. It is noted that on Sunday 30 November a plaque on the KMR clubhouse remembering Colin Burleigh was dedicated. (For protection it is situated inside, and only visible when the clubhouse door is opened). Colin’s family also dedicated a seat at the Seaview side of the Dell, looking out over Raumati Beach towards Kapiti Island. The Seaview Track Extension was fulfillment of his vision for KMR progress. Colin is remembered with respect and affection by the club, and the model engineering fraternity for his tireless work as MEANZ President over 10 years. *5* Above - the underside of the new cylinder assembly for Dart. Right - The cylinders after fitting in the frames and the motion is shown below. ! Photos - Peter Targett. “Dart” Update - Peter Targett Since the last update in the November Blast Pipe it was time to tackle the big job of the cylinders, end caps, valve chest, valves, valve buckles piston, glands and con rods. To save on cost I've gone for cast iron to replace the original gun metal castings. I've also opted for ‘O’ rings rather than cast iron rings. David Brownlow runs his Fairlie on ‘O’ rings and with the km's he puts in every year there's no doubt they work fine. The mounting holes for the cylinders were drilled using the location of the mounting holes I'd mapped from the frames. There was a moment of "I hope this works" but everything lined up perfectly when installed in the frames. The holes in cross head slide bars, already fitted in the motion plate, landed exactly on their holes in the rear cylinder covers. Once it was all back together it had to be tried on air for the first time. http://youtu.be/IZ7_Q0THENo. It knocked a bit. The con-rods were fouling the bottom of the opening in the motion plate and the valve timing had only been roughly set up. The motion plate was quickly removed and the 25 thou taken off the bottom of the opening, and a bit of time has now been spent on setting up the valves and pinning everything in place. Oldest Model Railway Claude was reminded of his visit to York NR Museum by a recent quote in Geoff Theasby’s Model Engineer Club News (#4491, p463) “The L&Y Railway School signalling display, a model layout with interlocked lever frames, block instruments and running electrically powered trains built by Basset Lowke in 1912, has been officially designated the world’s oldest working model railway!” It was used to teach signallers and was upgraded with colour light signals and catenaries, remaining in use until 1995. ME Newsletters With the number of clubs that are no longer posting newsletters to the other clubs, keeping in touch with what is happening around the country is not so ‘in front of us’. To get a bigger picture you might like to visit the website put up by other clubs. You will find a list of the affiliated clubs with locations, contacts, and websites that may help in your search on the MEANZ website, hosted by Palmerston North but accessible on its own address www.meanz.org/ Railex 2014 - William Taylor Wellington’s 2014’s Railex in mid November certainly was an excellent event which operated in the Porirua Kennel Club premises which provided a much larger venue than the previous two years. There were many rail organizations, there including ours, as represented by Alan Spinks who had ‘Brynglas’ on display, as well as Murray McKenzie, who had some of his stationary engines operating throughout the weekend. I was personally there representing The Hutt Valley Model Railway Club who were operating their HO gauge layout ‘Rocky River Railroad’, while the juniors were operating their own ‘NZ120’ scale layout that is completely maintained and partially built by them. A few other notable displays included the “Wellington British Railway Modeller” club’s ‘N’scale layout with all locos running with sound decoders and a fully automated signalling system that was very impressive to see operating. The Marklin Model Railway Club’s ‘1’ scale layout was operating over a very large space in the main room as well as many other layouts. All in all it was a very impressive Railex this year and it will be interesting to see what happens in 2015. Preserved Portable Steam Engine In 1981 while holidaying at Totaranui I went on a family walk to Awaroa Inlet and looked for the ‘steam engine’ left in one of the valleys. At that stage it was a rusty wreck in light bush, leaning at 15 degrees with tall grass and growth all around it. Blast Pipe February 2015 *6* 5”G 4-4-0 Virginia named Diana has been placed on Trademe several times by Ross Johnson. It is again on offer at a ‘Buy now’ of $7000 with trolley etc. Closing on 5 Feb. It would be nice if it could be retained in the area! - And if it does not sell we may see it over Waitangi weekend so you might get a chance to try it out. Myford Super 7 Lathe Portable engine at Awaroa Inlet as presented now. The single cylinder inverted vertical engine is on the end opposite the firebox of the return tube boiler. The smokebox is within the barrel above the firebox and the uptake goes up through the water/steam space above. The DOC history of the area states “At Awaroa, John Black used a steam engine to drive a mill which ground bark.” This bark product was at the time used in the process of tanning. This year I took the opportunity to pay another visit and found it had been ‘preserved’ in DOC terminology. Nick Jarman told me that it was so close to being barged out of the area by enthusiasts who wanted to ‘restore’ it when DOC actioned the improved interpretation of its presence in the park. As the photos show it is a rather sophisticated portable with a complex boiler and vertical engine configuration. So far I have not been able to find its design origin, or the builder so please let the editor know if you can locate any more details.
