Re: Brimsdown-The last grand project.

Why bother? You can get your PCBs from China exactly to your required size and they are double sided for pennies.

Re: PCB Etching

I suggest you get it drawn up in a PCB software package and get China to produce them for you. With your dimensions you would get about 40 for£12 ish.

Try SEEED Fusion (https://www.seeedstudio.com/fusion_pcb.html) or JLCPCB (https://jlcpcb.com).

Re: 00/EM wheels turned down to 18.83 standards

I was wondering if it is possible to turn a 00/EM wheel in a lathe to 18.83 standards? The reason I'm asking is because I have some RT models slag ladle kits which use a markits 8mm wheel. I cannot get these wheels anywhere else & markits don't supply them in p4. Can a wheel be turned down ? Ar...

Re: Who would want a form tool for re-profiling wheels?

The Scale 7 Group produce two Form tools for use with S7.

The circular type is easier to sharpen.

Re: Wormdrive sleeves

If you have a shaft of 0.78mm (0.0307") and a hole of 0.7925mm (0.0312"). Then you have 0.0125mm (0.0005") clearance. That is well within the tolerance/requirement of a sliding fit. In fact it's a bit tight - you may have difficulty getting it on.
