murrayec Posted May 11, 2017 Author 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
murrayec Posted May 11, 2017 Author 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
murrayec Posted May 14, 2017 Author 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
Mike 84C Posted May 14, 2017 Posted May 14, 2017 Eoin, that looks seriously good, you are a talented modeller. Quote
JasonB Posted May 14, 2017 Posted May 14, 2017 That's a serious piece of engineering that most of us could only dream about producing.Really top class work Quote
murrayec Posted May 14, 2017 Author Posted May 14, 2017 Hi All Thanks for great comments Yes Kirley, I'm really having fun- I look forward to working on this when I get the time. Painting the patterns tomorrow night and hopefully moulding will start after Eoin Quote
Noel Posted May 14, 2017 Posted May 14, 2017 Great bit of model engineering Eoin. The bogie sides look alsolutely superb. Quote
murrayec Posted May 15, 2017 Author Posted May 15, 2017 (edited) Hi Thanks again for the comments Here is the video of the second bogie without the spring under test, the full chassis and model body on;- Eoin Edited May 15, 2017 by murrayec Quote
DiveController Posted May 16, 2017 Posted May 16, 2017 That looks good, Eoin! When might it be available? Quote
murrayec Posted May 16, 2017 Author Posted May 16, 2017 That looks good, Eoin! When might it be available? 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
David Posted May 16, 2017 Posted May 16, 2017 What wheels did you use for the non powered axles? Quote
murrayec Posted May 17, 2017 Author Posted May 17, 2017 Hi David Their just standard 12.6mm Hornby replacement coach wheels, having problems finding better wheels in that size! These wheels are used in the spud also... Eoin Quote
David Posted May 17, 2017 Posted May 17, 2017 Ah yes, I was thinking they looked familiar. Pity the price of them more that doubled recently. Quote
murrayec Posted June 22, 2017 Author 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
patrick Posted June 22, 2017 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
murrayec Posted June 22, 2017 Author 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
murrayec Posted September 13, 2017 Author Posted September 13, 2017 (edited) 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. 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
murrayec Posted September 15, 2017 Author 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
murrayec Posted October 11, 2017 Author 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...

Stephen Thanks StevieB Yes I can run off a set for you if you want, a set of 4 is €25.00.... they will need a slight clean up with sharp knife, a file and fibre brush Eoin Quote

I'm in England and PayPal would be the easiest way. Thanks. And will the chassis be commercially available at some point, with or without the sideframe castings? Quote

Hi decauville1126 I'll put you in the mix for a set, the chassis will be available soon, it still needs a bit of work to finalise, and it will be available as components as required, or ready to run I will pm you as soon as I check out postal cost for the sides to England Eoin Quote
Glenderg Posted October 12, 2017 Posted October 12, 2017 Will the wee step ladder on the bogie sideframe be available too :P Only windin' ya up, they look "is maith sin" or "smashin'", love to see this level of fidelity with Irish stuff, EMC abu! R. Quote

R. Hi R. Yes it will be available later... I did NS wire ones for the Class C sides but to much fiddly work, so the A's will be brass etched, to be folded up and soldered! Eoin Quote
