murrayec Posted May 11, 2017 Author Share Posted May 11, 2017 I was thinking that if the bogie sides were moulded from resin then maybe youcould attach the front axle to the bogie sides instead of the brass bracket. Hi popeye Yes I have a design for using the sides to hold the third axle, but I prefer to keep the axles and motor as one stand alone unit and bogies as independent units. After my testing of this design you never know I may revert.... Eoin Quote Link to comment Share on other sites More sharing options...
murrayec Posted May 11, 2017 Author Share Posted May 11, 2017 Just wondering if this will have room to fit broad gauge wheelsets? Hi RichL Yes it will work with 21mm gauge wheelsets if that's what you mean, a little bit of filing for wheel clearance on the frame sides is all thats needed Eoin Quote Link to comment Share on other sites More sharing options...
murrayec Posted May 14, 2017 Author Share Posted May 14, 2017 Hi All I got the second bogie made up and ran some tests on it, this one does not have the wire spring for the pony truck and a small bit of lead tucked in under the frame- surprisingly it runs better without the spring! So the chassis plate was stuck together, the fixing brackets to hold it on to body were installed, an internal metal weight bolted down to the chassis plate. I used one of my Class C white metal battery boxes to add weight and detail- the A one is not made yet! and I ran the chassis without the body- it ran brilliantly. Now that I have the whole loco test assembled the bogie side patterns could get their final test fitting. All works fine and no need for adjustments to the patterns. They are now off to the paint shop to finish for making the moulds... Eoin Quote Link to comment Share on other sites More sharing options...

Hi DC I'm pretty close to all being sorted, I'm tipping away at it while I finish the other things! Then I have six orders to do- these kits have been on the high shelf for about 2 years now!! I also need to work out my pricing Say about 2 months, though I have said that before Eoin Quote Link to comment Share on other sites More sharing options...

patrick Posted June 22, 2017 Share Posted June 22, 2017 Any plans for a coupler mount on the bogies? Quote Link to comment Share on other sites More sharing options...
murrayec Posted June 22, 2017 Author Share Posted June 22, 2017 Hi patrick I'm really only working with the coupler off the chassis, the pony truck may cause trouble for mounting a coupler! and the SF buffer beam is in the way! but could see what happens, Have you something in mind? Eoin Quote Link to comment Share on other sites More sharing options...
patrick Posted June 22, 2017 Share Posted June 22, 2017 My concern is about mixing body mounted couplers with bogie mounted couplers which cause problems on curves epically when pushing rolling stock through points during shunting movements. A bracket on the end of the bogie frame with provision for mounting a cupler pocket would be perfect. Quote Link to comment Share on other sites More sharing options...
murrayec Posted June 22, 2017 Author Share Posted June 22, 2017 Hi patrick Next time the test track is up I'll push some rolling stock through the points, I did test the chassis with a couple of Cravens forward and backwards through the points with no problems, but did not test something smaller/lighter without the close coupling unit!! I will report back Eoin Quote Link to comment Share on other sites More sharing options...

A bracket on the end of the bogie frame with provision for mounting a cupler pocket would be perfect. Hi Patrick Finally got to run tests on the chassis mounted coupler- it's fine running backwards through points with wagons, but not with a Craven coach- serious lock with the chassis mounted system. When last testing I must not have pushed them backwards! The way I designed the bogie with the little free truck at the front will not be suitable for mounting the coupler from there so I reckon its going to be some type of coupler plate off the chassis to allow more side swing! like a Keen Plate- but they are two wide. This will also require a wider slot in the body buffer beam as coupler height in within the beam area.... Some drawing is required Eoin Edited September 13, 2017 by murrayec Quote Link to comment Share on other sites More sharing options...
murrayec Posted September 15, 2017 Author Share Posted September 15, 2017 I think I have it sorted! The Class A buffers were also locking with the Craven's in reverse- and sorting this problem lead to the solution. I extended out the NEM socket on the Craven so that the coupler buckle was beyond the line of the buffers, it then came to me that if I opened out the side of the 156 Gear Box on the A chassis to give the coupler a bit more swing it may work, it's done and it does. Now the couplers hit the buffers but it does not lock up, it drives backwards through the short Hornby points OK.... Until next time I have the track up I'll post a few picks n video Quote Link to comment Share on other sites More sharing options...
murrayec Posted October 11, 2017 Author Share Posted October 11, 2017 Hi All After a week of mould making and a bit of a compromise on pattern detail the Class A Bogie Sides started to appear, I'm still experiencing venting and chilling problems, but came up with a technique that gave 80% success- some of the detail is to fine for this kind of moulding without a centrifuge...
