Re: Here We Go... Judith Edge Ruston 48DS Kit

Hi Richard,

Nice work, I have only just tuned in as I bought a Judith Edge kit recently.

For your modified compensation whose hornblocks did you use?

Thanks

Re: Brittle K&L chairs

Allan Goodwillie sugested that the problem could be exposure to UV light and careful coating in solvent might form a surface repair. I am going to try that on some that I know are brittle, not all are. Where these were "stored" they could been exposed to UV. Allan cited the problem that yo...

Re: Brittle K&L chairs

Hi,
Thanks guys. Some unused chairs are ok, but I guess I will have to wait for C&L's successor to be back in the stream. I may have enough to finish this test track.
Thanks.

Brittle K&L chairs

Hi,
I am trying to use up some twenty year old plastic two bolt chairs. I am aware of the interregnum as regards C&L so cannot order more.

Is this turning brittle a known problem? What about the chairs that I have used as functional chairs?

Re: Electro magnets for AJs

Hi, my tuppence worth. Keith, above, is right about wire size. I have used 16/0.2 wire for this task, it's resistivity is a lot less than 7/0.2. Avoid parallel feed, go for single magnet operation. I preference the SEEP magnet to others. Wire obtained from City Electrical Factors, CEF, is generally ...

Re: Livingston - West Lothian Starters Group

Hi Allan, Thanks for the compliment about the design of my jig, it was very simple to throw the bits together, I had some tapped M3 hex brass spacers in my collection of bits. The original plan was to check the compensation pivot to achieve a "horizontal" chassis only. Then the steel rule ...

Hawthorn Leslie 0-4-0 Well I now have a completed and running chassis. HarthornLeslieChassis.jpg Now I have to do one more thing, ensure that the pivot for the compensated axle is in the right position vertically. If I attach some M3 hex spacers with M3 screws to the two chassis holes I can rest a ...

Re: Livingston - West Lothian Starters Group

Yes, Thanks for that, I have subsequently been told that they get stuck fast. Apparently you should apply a small amount of oil to the hole before inserting the smoothing broach, then proceed with great care not to force things.

I don't have any, so it is not a problem that I will encounter.

Re: Pin Chucks

Hi, I have a number of Eclipse pin vices, some of which I inherited and some I have bought. They work well for me. I do tend to have "favourite" sizes kept "loaded". Eclipse seem to endure better than others. I have "recycled" my non Eclipse pin vices, they did not endu...

Re: Livingston - West Lothian Starters Group

Hi, I usually fit the file tang into the round hole and using the weight of the file, I drop the combination, handle downwards, onto a hard surface, like a bench or workshop floor. The height needs to be about a foot or 300mm. Some times you have to repeat a couple of times. To disengage the file re...

File types and usage. Hi, again during one of the group sessions, sounds like therapy doesn't it, I mentioned about the hand file having a safe edge. There were a number who were unaware of this feature and it's uses. So a quick tutorial on files. Pictured below are a selection of 6" (150mm) f...

Re: Livingston - West Lothian Starters Group

Hi, More on the coupling rod jig. There was a discussion about the make up of the pins that the coupling rods are assembled on. Allan firmed down on M2 studding, there has been discussion else where that had suggested 8BA. So for M2 studding we need a 2mm gap. Using 8BA would need a gap of 2.2mm. Th...
