Very useful John, thank you. I’ve tried it in a desktop Mac and an iPad and it works fine on both.

Re: RE: Form tools

Thanks Ivan. Looking at the image of the tool itself, it does appear possible to sharpen it by grinding the top face as the contoured part looks to extend down to the bottom.

Re: RE: Form tools

The Teichmann tool looks to be quite straight forward to use. However it does not seem to incorporate the 20 degree angle we usually favour for the tread. Am I correct in thinking this or did I miss something?

A fret of chopper couplings can be obtained from Branchlines nowadays. Either five or five pairs per pack.


Thanks Ivan. They look the part, I just wonder how practical they would be for operating.

Re: Best Glue for the job!

I’m not sure if LePage is available in the UK but their product “No More Nails” does the job. Barring that adhesive caulk should do the job, just make sure you get something for indoor use as the outdoor stuff has an awful pong. :?

Re: Turning a chimney

I can think of two advantages for a rear mounted tool post, specifically one dedicated to parting tool use. First: the tool would only have to be adjusted once for cutting height until such time as it needed sharpening thus saving the faff that occurs even with rotating tool posts of getting everyth...

Hi Peter, Not a Perseverance chassis but an SEF one for the Hattons SECR P class but I suspect the experience would be similar.

Paul, Brass can be a pain as drill bits tend to grab. The problems you are encountering along with similar problems encountered by others on the forum caused a memory (or something) in my mind to click that there was a better way of drilling brass and there is; https://www.model-engineer.co.uk/forum...

Re: Easing wheels tight to gauge

There is another way to shift wheels without resorting to brute force. I posted an article to Scalefour News 145 (December 2005) P9 describing how to make a wheel puller from a cheap G cramp (clamp). It works in the same fashion as the as the GW one but instead of pulling at the rim it applies the f...

A Canadian invention as it happens, https://www.robertsonscrew.com/. Far superior to Phillips heads IMHO as they don't strip as quickly and the screw can easily be carried to the job on the screwdriver tip.
