    Up until recently I have been a Great Western modeller specialising in locomotive construction in EM gauge and am a joint owner of the Hungerford exhibition layout. More recently I have been focused on building Clayton which is an ex GNR post grouping exhibition layout built to EM gauge.

  1. What liquid do you use in your ultrasonic bath? Frank
  2. Hi Tony, Your assumptions are correct. The model will now be dismantled for painting (hopefully by that nice Mr Rathbone) including a wheel from each axle to allow them to be removed from the frames. The exception to this is the tender's inside frames which I have already painted with cellulose rattle can paint but only because of the need to fully install the ball races used in my 'motor in tender' drive system in order to test run the model. I don't think the bearings would react well to being subsequently sprayed with paint. When the chassis is reassembled the wheels will
  3. A few days/weeks ago we were discussing our Covid-19 activity. Today I have completed a project that has been progressed entirely within Lockdown, from initial research and design, through two test builds, to a fully assembled model. The J1 is the 4th loco developed specifically for Shipley MRS's Clayton project and for which no kit is currently available. The initial test build, whilst highly informative, was ultimately frustrating because it did not deliver a completed model. I did end up with a usable chassis but the build of the superstructure hit problems early on when I realised tha
  4. Hi Tom. Can I recommend you use the relationship of the cylinders (especially the piston rod) to the driving wheel centres to work out where the discrepancy actually resides. If you take metal from the top of the frames I would anticipate that this will cause the cylinders to drop as well, but I had thought from your earlier posts that you'd already sorted out the relationshp of the cylinders and the wheels? Measure twice, cut once as the saying goes. Best of luck Tom, Frank
  5. Hi Jol, Improved pickup - yes, better adhesion - no, we've been here before. Improved adhesion is not supported by the maths, and has been demonstrated as incorrect by experiment. Apologies, Frank
  6. Not forgetting the need for suitable (finescale) track then yes you would be correct, as would be the case if using Ultrascale wheels. With Gibson wheels the ride will be acceptable but not quite as even. In actual operation on a layout I doubt you would be able to tell the difference. You may be interested in the following videos which I prepared to compare and contrast the look and ride characteristics of Gibson v's Ultrascale wheels. When I recently built my J7's to test assemble the etches I had designed I fitted one of them with Gibson wheels and the other with Ultrascale
  7. Hi, Don't know what the minimum radius you are aiming for is? The way I arranged the bogie meant that there was no need to cut away the inside of the cylinders to allow for swing of the front bogie wheel in EM. It will be even better with OO clearances. The benefit of the control pin at the rear of the bogie is that it stops the main frames from swinging too far in either direction which is normally the case if it is only the coupled wheels controlling the swing. It also stops the rear bogie wheels touching the main frames. I should add that I still needed the centre bogie pivot ins
  8. Hi Graham, I converted a Bachman C1 to EM recently and documemnted on WW a couple of months ago. I've fitted 14mm bogie wheels without problem. I set up the chassis so that the bogie controlled the vertical movement of the front of the chassis to prevent the footplate from grounding on top of the bogie wheels. The chassis sits on a pin centred directly above the rear bogie wheel. As well as controlling vertical movement this pin also prevents sideways movement so there is no requirement for a cut out to allow the rear bogie wheel to pass under the frames. The bogie then rotates aroun
  9. Hi Tony, I can't disagree with anything you have said but as someone who universally uses plastic centred wheels I feel I can hopefully provide a balance to your statements. I agree with Mr Gee that Ultrascale wheels are built to a very high standard and are not subject to many of the issues that you have mentioned. Gibson wheels by comparison have improved significantly since the new owner took over the business but they are still not perfect. Eccentricity remains a problem with Gibson wheels albeit minor by compartison to before. I would definitely steer away from
  10. How about a 2 car (both 12 wheelers) Pullman? Two of the Yorkshire Pullman cars originated and terminated at Halifax and traversed the Queensbury lines through Clayton hauled by an N1 or N2 locomotive carrying the express head code. I hope Headstock wont mind if I report that he is currently assisting the Clayton team in bashing a couple of Hornby Pullman cars into shape for our Clayton layout. A loco plus two on a 30 foot layout should well and truely look lost in the scenery. Frank
  11. Have you checked the file sizes of the images you are trying to load? Frank
