Re: Brassmasters Blk5 45232

David, I read CP’s notes on crank pins and return cranks again this evening (MRJ 219). It seems he does still rely on torque tightening to secure things but all is scaled up from 14BA. He makes his own crank pins and 12BA crank pin nuts. Thin copper shims, made with a home made punch, are used as sp...

Re: Brassmasters Blk5 45232

Pete, A small square escapement file is what you’ll need. Although these can be quite pricey and delicate. ISTR that Chris P ground down the tip of a more reasonably priced flat file to a suitable size. The other option is etch some replacement return cranks with a square hole in them. Slightly unde...

Re: Brassmasters Blk5 45232

Some have suggested threading the crank and screwing it on. Looking forward to seeing how you proceed with this. Some really nice work going on here Dave. Following with interest. Hope you don't mind If I chip in here Dave and David? Threading a hole in the return crank and tightening it up against...

Re: Chris Wesson Cellulose Paints

When spraying cellulose I have also found it important to use good quality "high gloss" cellulose thinners. The "ordinary" thinners, sometimes referred to as Gun Wash can make it difficult to get a good result. Absolutely, it is a must. Premium, high gloss, or slow thinners gets...

Re: Hornby B12

A positive goer though is to remove the Hornby tread and reduce the plastic centre to take a Gibson tyre. For this again you will require a lathe of sorts and a mandrel. The axle hole can be reamed out to take an appropriate axle, new axles made and the wheel pressed on in the usual way. I have see...

Thanks Morgan That example seems to have a much lower cab than the one in the picture I linked too.

Re: Johnson 2f, what are the options?

Hi Jim, I'd ask John Redrup or Jol Wilkinson about the LRM kit. IIRC it's origin is from the George Norton range and it is possible that the kit had the later LMS cab included in the etches. Alternatively the Alan Gibson range has/had a 2F with both type of cab. I believe the model I acquired and re...

Re: Help with a Brassmasters 4F

Russ, When you say "tighten the middle axle" I presume you mean the effective spring stiffness to be slightly greater than the two outer axles? This would lead to a tendency for the chassis to see-saw on the middle axle but as your diagram does not have any deflection scaling it is impossi...

Re: Help with a Brassmasters 4F

Here are the photos showing ride height. Without boiler things look ok. But with the boiler, that has a large bar of steel inside, I think a 0.25mm packer will still be required front and rear.

Re: Help with a Brassmasters 4F

I've found that if built 'as designed' the loco ride height is wrong. I have been slowly resurrecting a 4F that had been built to P4 but using the EM spacers in the kit. This turned out to be advantageous in correcting the ride height but very inconvenient for making the inside valve gear fit and wo...

Ok, thanks John. I agree it is a bit late to ask. I'll print one out as a precaution but may just see if I can get in "airport style". When I saw the QR code on the ticket I assumed, perhaps wrongly, that a code reader might be on hand at the door.

A measurement device with only a 2 decimal place accuracy will no doubt be a vernier caliper, colloquially known ...

Re: Getting the wheels on square!

Davis, yes, I realised that when re-reading a few bits again, apologies. I doubt that the bearings are made deliberately undersize. Over the years I've had plenty that have been too loose on axles. These get binned. What I do see a lot of is burrs and hanging swarf on the bore edges of bearing. A qu...
