David Bigcheeseplant Posted May 2, 2020 Share Posted May 2, 2020 Has anyone got close up photos or drawings of the autocoach control gear taken from the driving end and non driving end of GWR autocoches as I plan to do a detail etch, although the lockdown stops me from making a visit to Didcot to do it myself.

d00m Posted May 2, 2020 Share Posted May 2, 2020 (edited) I saw a programme on telly South Devon Railway with views of both ends. You can probably find what you want on youtube typing in GWR auto trains. There are quite a few on there. Edited May 2, 2020 by d00m Link to post Share on other sites More sharing options...
David Bigcheeseplant Posted May 3, 2020 Author Share Posted May 3, 2020 I have plenty of pics but mostly the autogear is in the shadows, so really need close up detail views David Link to post Share on other sites More sharing options...
RMweb Premium Siberian Snooper Posted May 3, 2020 RMweb Premium Share Posted May 3, 2020 I have some diagrams that are supplied with Dart Castingsauto coach detailing kit which I found to be useful, I could scan it for you. The only snag is that it's in the club room and is not currently accessible, due to the current situation. Link to post Share on other sites More sharing options...

Although the Dart Castings bits don’t tend to fold up and locate that well hence I wanted to do something better. And would rather start from the prototype rather than another model.

RMweb Premium Siberian Snooper Posted May 4, 2020 RMweb Premium Share Posted May 4, 2020 I am actually using the bits from David Geens Auto coach kit, but the destructions from Dart Casting are clearer. I do however use the steps and some of the castings from the kit. Sorry that you won't be able to get the David Geen bits. Link to post Share on other sites More sharing options...
kandc_au Posted May 4, 2020 Share Posted May 4, 2020 I should imagine if you do them you will also have a market for some as well....hint, hint! Khris Link to post Share on other sites More sharing options...

I do have that book and it does show how it works although I really need to get close and measure all the bits. David Link to post Share on other sites More sharing options...
RMweb Gold The Johnster Posted May 5, 2020 RMweb Gold Share Posted May 5, 2020 (edited) Some pretty good descriptive photographs as well. Sorted. Maybe a visit to Didcot is in order, when the panicdemic is over! Edited May 5, 2020 by The Johnster Link to post Share on other sites More sharing options...
Coach bogie Posted May 11, 2020 Share Posted May 11, 2020 Here is the David Geen etch. He does have these in stock. I use them for slip coaches. Mike Wiltshire Link to post Share on other sites More sharing options...
David Bigcheeseplant Posted August 3, 2020 Author Share Posted August 3, 2020 (edited) Its been a while but I managed to get to Didcot to look at and measure the autocoach control gear on the steam railmotor tailer 93 and autocoach 190, unfortunately autocoach 231 was locked away in the paint shop. There are differences between the auto gear on 93 and 190 so I have used 190 as the basis of my design. Next up I will 3D print what I have drawn and if it fits draw it up for an etch. The idea is that it can be built up on a baseplate then stuck to the underside of the floor of the Bachman model. I still need to draw up the control gear for the non driving end too.

David Bigcheeseplant Posted August 4, 2020 Author Share Posted August 4, 2020 Quote I Just printed off the autogear and other than a few minor tweeks it fits under the driving end really well, I was going to redraw the parts for an etch but looking how this D print came out as a single piece I think I may just stick with the D print as its probably finer than soldering up an etch and a piece of cake to stick it in place too, I will now draw up the bits for the other end. Once I have these I will offer the parts for sale please let me know those who are interested. David 3 2 Link to post Share on other sites More sharing options...
jbg Posted August 4, 2020 Share Posted August 4, 2020 That looks good David. Will need a couple of sets please. I’ll try and get to finishing the interior for the Comet kit in a few days and post some photos. Thanks Jeremy Link to post Share on other sites More sharing options...
David Bigcheeseplant Posted August 5, 2020 Author Share Posted August 5, 2020 Second print run with some mods, I really can't believe how fine I managed to get these printed, the little 0.2mm hole where the control gear links to the next coach has been printed plus a hexagonal bolt head! I really don't think I could get these finer by etching. Now to work up the bits under the luggage end. What is good about these is that is a simple one piece part that glues straight on to the underside of the floor. 7 5 Link to post Share on other sites More sharing options...

RMweb Gold 57xx Posted August 6, 2020 RMweb Gold Share Posted August 6, 2020 Looks ideal for the old Airfix/Hornby autocoach too. I've got a pic of 231 that I'll PM to you. Link to post Share on other sites More sharing options...
David Bigcheeseplant Posted August 6, 2020 Author Share Posted August 6, 2020 After a number of requests I have scaled the print up for 7mm scale, these prints failed on one of the linkages but I can sort that out, i worked fine on yesterdays print but I did make some changes. The cost of the 4mm versions are £7.50 plus postage I need to cost the price for the 7mm version. I only went live with these last night and already have quite a few orders, I think my printer will be busy! David 1 Link to post Share on other sites More sharing options...
David Bigcheeseplant Posted August 8, 2020 Author Share Posted August 8, 2020 Some more prints with some red primer I have added the tension spring and the control rod and I think this is as far as I go with any tweaks. I am looking to get some cardboard tubes to post these, and have started to batch print now. so once I know costings of P&P I will be in contact with people who have placed orders.

David Bigcheeseplant Posted August 12, 2020 Author Share Posted August 12, 2020 I have now drawn up the rear autogear and am doing a test print 4mm and 7mm scales now. I have been looking at photos books and MRJ 8 where Mike Clark did drawings of the diagram A30 & A28 It seems the Control rod on the A30, A38, A39, A40 and A43 ran on one side only while on the A28 and I expect A27 and A28 it changed sides half way along the coach so at the rear end the arm to this will be at a different side, so I may have to do a couple of variations . 2 Link to post Share on other sites More sharing options...
RMweb Gold The Johnster Posted August 12, 2020 RMweb Gold Share Posted August 12, 2020 (edited) So, the thing you really want to hear about now is more variations, right? A43/4 had flat ends, as did the Sharpness-Lydney Severn Bridge Brake Composties that I can't remember the diagram number of off hand (A34?). Then there were the Clifton Downs coaches and similar, including some converted Dean clerestories, and the original steam railmotor which was converted to no.1 in the auto numbering series. Some of these flatenders were intermediate all 3rd compartment stock, which require flat end gear but no connection to the regulator in the driving cab as there was no driving cab.

I do know most of the variations as I have the two volumes of the Wild Swan autocoach books it is really the control gear which I need to find the variations on. have now printed the rear autogear which has come out well as per the photos, prices are in 4mm scale £7.50 just for the driving end and £14 for the driving end and language end. In 7mm scale the prices are £13 for the driving end and £24 for both. I need to check postage rates to see if the boxes I will collect tomorrow will be large letter or a small parcel. The auto control rod I have modelled up against the end of the coach I can amend it down to show it connected up, although I am going on that when running on the layout the crew didn't bother linking it up as it was too much hassle.
