Re: Drill for rivets.

The rivets have a diameter of 1.1mm and the same goes for the hole punch. A drill should be the same. Rgds I always thought they were 1.3mm diameter, but Joe Brook Smith's original P4 sleeper drawing actually specifies 1.27mm hole diameter +/- 0.025. Incidentally, this is the same diameter as Songs...

Re: Brimsdown-The last grand project.

I also have a new definition of tedium, cutting 9' sleepers down to 8' 6". Here's a saw trolley, used to cut 9' sleepers down to 8' 6" so that old track panels, once lifted, could fit between the stanchions on a Morris Tracklayer. There's a prototype for everything! Screen Shot 2019-03-27...

Re: Making a Start - The Peak District Midland / Monsal Dale pre 1903

Hi Tim, Regarding your drilling question, centre drills are designed for making holes in the ends of a workpiece so it can be turned between centres on a lathe, not for spotting holes in order to start a twist drill. The geometry of a centre drill is such that the hole it creates matches the geometr...

Hi Mike,

The last image in your post is intriguing. I'd be interested in seeing a close-up of your wheel testing set-up and the information on that piece of paper in the foreground. What tolerances have you set for wheel wobble and eccentricity?

Re: How tight should a pair of wheels be to the B2B gauge?

Using a back-to-back gauge effectively is dependent on the user appreciating the right feel of the gauge between two wheels. This feel is difficult to convey in words or pictures – perhaps there’s call for a video on the subject? In order to appreciate the right feel, why not measure your gauge with...

Re: Best way to fabricate multiple metal parts?

To tension the blade you rest the frame against the edge of the bench and the end of the handle in your belly just below your sternum and lean forward slightly. Sounds appropriate for some sort of hair-shirt ceremony, but I'm not sure of the utility at the workbench. Personally, if there's an easie...

Re: Soldering Irons

For our type of soldering, i.e. non-electronic, solid copper bits are far more suitable than plated ones. Having tried copper, I don't think I'd ever go back to plated bits.

Re: Delivering the Goods

All this is by way of a digression from what I had originally intended to write on the topic of brakes. By BoT regulations made in 1911, all new wagons built after May 1912 had to have brakes on both sides. Retro-fitting of existing wagons was spread over a long period, depending on the number of w...

Noel, Thanks for your comments. They have spurred me on to resolve a long-standing query I had regarding the brakegear on these wagons.

I've drawn a little sketch to assuage those who fear a reduced contact area between cosmetic chair and 'punched' ply sleeper.

Surely the last thing you want to be doing is sticking chairs down over holes, you need as large a contact area as possible to ensure a secure bond. If the society cannot provide these we are forced to go to C&L for them? But considering that the holes on the underside of plastic chairs (2.0mm ...
