Re: Advice on Chassis jigs

I invested in an Avonside chassis jig last year. Using that together with a GW Models Wheel Press & Quartering Jig, not to mention a High Level gearbox, I managed to produce for the first time a loco that ran sweetly from the start without the need of any tweaking whatever. Highly recommended. DT

Re: Ultrascale Brass Wheels

Anymore brass stories out there, or do Ultrascale advertise them as some sort of 'in-house' joke? When I was at the Glasgow model railway show this weekend I spoke to the operator of an EM gauge layout who told me that all his locos (diesel) and rolling stock are fitted with brass wheels (albeit no...

Tool List buy a caliper gauge, you get very nice digital ones out of places like Liddle at a very reasonable price, once you have one it will surprise you how often you will use it.

Re: EM wheels on P4 track

The difficulty with your case, Rodney, is that whatever the arithmetic calculations may point to, actual practice seems to produce a different result. You suggest that the use of EM wheels will cause problems. But Martin (Goodall) was specifically asked at one point: "Are you claiming that by u...

That's all very well, but Martin Goodall assures us that his track is built to P4 standards: "First, my track is built to P4 standards. Flangeway and check rail clearances are all within P4 tolerances; they have not been adjusted in any way to accommodate the EM-profile wheels". As far as ...

Re: Wagon Suspension

A little off topic ("Wagon" suspension), but I assume that while rolling stock with EM profile wheels runs on P4 track, the same cannot be said of locos?

Re: Wagon Suspension

I dont see why it should IF as Martin states that he isnt using P4 standards. Which he isn't and indeed hasn't claimed he is here. He is just using EM standards set to a wider gauge. As some P4 modellers model Irish gauge its not the gap between the wheels that defines the standard but the wheels a...

Re: Split frames

Thanks for that, Tim. John's method seems eminently logical and sensible, and I shall equip myself with some Brassmaster hornblocks and give it a go. Obviously it can't be combined with Mark's split axle method, so I assume that you just split your chassis frames in the usual way and insulate them f...

I have used the John Brighton system of Brassmasters hornblocks over several locos, amended for split frames, with complete satisfaction. Using his methods I can build a working chassis first time and very quickly. I'm afraid I don't know about the John Brighton system, and I haven't used the Brass...

If you use the method I have described above, the frames will not be live and insulation will not be required.

Re: Split frames

I'm not sure what you mean by "the additional bits around the hornguides". If you use Mark Humphry's method, you first solder a piece of thin PCB on the inside of the frame over the area where the hornblock cut-out is going to be. You then cut out your hornblock slot, ie cutting through bo...

Re: Split frames

I'm presently experimenting with the split axle system advocated by Mark Humphrys in E4um back in 2003.

Re: Driving wheel axle material

Thanks, Russ. I had a feeling that brass on brass was not going to be satisfactory. And Andy, Branchlines do do split axles, but rather than one steel tube, as with Bill's, theirs are made up of three separate units, similar to the Society's ones. There must be 1/8th steel tube available somewhere! ...

Yes, it is a High level kit. So far it has required the use of four bolts - three M2s and a "14BA C/S bolt, cut to about 4mm long". Only two M2 bolts, each about 20mm long, were supplied. I've got a pack of M2s, so they're not a problem, but if I can't get a 14BA bolt at the Dundee show th...
