Re: Driving wheel axle material

Brass axles - possibly, if you used steel bearings, however, it wouldn't be good engineering practice. The problem would be getting exact 1/8" diameter, although it might say it is, that's only a nominal diameter. Some gear wheels have a 1/8" hole through, put that on a slightly undersized...

Re: GW Wheel Press

No.

It is set up for 1/8" axles.

It is actually bogie and tender wheels I find are the worst for eccentricity, I find I've had to recentre more of these than drivers.

Re: GW Wheel Press

The GW wheel press puts both wheels on at the same time. The only wheels that are satisfactory for wobble and concentricity are Ultrascale. However, their range is limited. So other wheels have to be used. For standard wheel diameters (for me) i have a couple of ring chucks that I use to re-centre w...

Re: GW Wheel Press

Tony Wobble in wheels is a product of the wheel not the press. No press can guarantee wobble free wheels. Wheels could be pressed on by hand and not wobble, IF they were good wheels, unfortunately, most of the wheels we use in 4mm don't offer that. I spend a lot of time working on wheels, making sur...

Re: Tarpaulins - Any success/Ideas

Hollow sheeting is frowned upon, as the sheet, though proofed, is not guaranteed to be waterproof. There are "stern" instructions about this in the booklet referred to. The whole point of the sheet is to prevent the contents of the wagon getting wet.

Re: Track set in concrete hard standing.

Is it inlaid rails? Does traffic pass over them?

I just used plaster, but with PB rail, instead of my normal steel.

Re: Putting it all together - Part 1

Good idea, gives you a real chance to examine how it goes together, where the pitfalls are, what could be done better, what really annoys you about putting it up and what you can do about it. Away from setting up for an exhibition, with all the pressures that entails. Any thoughts on what went well,...

I have only used the standard Keen couplings, all my coaches run in sets, and don't need to uncouple.

Yes, I have successfully used the Keen centre couplings in P4 on 3' radius, they were the only ones I could get to work. how the couplings are fitted, in this case to the TOP of a Comet underframe.

Re: Wheels

I believe the Exactoscale wheels are scale width, the recommendation of a standard width of 2mm from the MRSG for wheels was for manufacturing expediency.

Re: Correct-ish colour in BR days

Personally I would avoid any low production run spray cans, I've had too many go wrong.

I'm quite happy sticking with the high sales volume Halfords etc cans (usual disclaimer).

In fact all wheels should be checked on their tyres only.

Re: Wall brackets

Surely any brackets from your local DIY emporium would do? Cast aluminium in a GWR style could be expensive.

I have considered it myself using the folding microwave brackets off my bookshelves, pop the test track on, take it off and fold the brackets away.
