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.

Re: Stour Valley Dream - progress on P4 layout

I took a look at Lightburn but I don't think it supports the commercial machines like my HPC laser. Hi Dave, It is always worth dropping these guys a line as they are very helpful and obliging. In view of the number of HPC machines around they may well be interested in adding in a driver for it - I...

Re: Track cleaning

It happens that I mention this in my article “Updating Highbridge” in the May Snoozef . My interim conclusion is that there is no advantage in using the expensive and inconvenient aerosol WD40 Contact Cleaner. Comparison between Propanol aka IPA and Heptane is ongoing. The results are pretty much t...

Re: Plywood disaster

I went against all conventional wisdom when I built the board for my Pelton Level layout and used 6mm MDF throughout. I did, however, make sure that the trackbed had full support along it's length as well as cross braces. In 12 months (part of which involved it sitting in an unheated garage) it did...

Re: Plywood disaster

In this instance it would appear that it is the ply rather than the MDF which has caused the issues? So investing in the more expensive option following on from advice taken seems to have caused issues not experienced before? Or maybe I have this wrong :? No Tim, you are spot on. Whilst I agree wit...

Re: GWR 44xx Kits

Interestingly the Churchward 45XX instructions refer to the 44XX.

They say a 44XX chassis would be produced in the future - obviously never done.

Hi Robin.
It would be useful to know. I have tried the ones I have got, which match the pitch of the connector, but they are not long enough. Curses.

There will be a transfer of load to the deflected wheel, which naturally cau...

If you look at the 1930 plan rather than the 1948 plan you will see that 25 had a FPL operated by 20. Was it actually removed in 1948 (and why?) or is this a mistake on the plan?
