Brake discs a suitable source of case iron

[Lee GriffithsParticipant @leegriffiths86022]

I've made all four axle boxes now from my disc and I'll update my estimate as I'm only used about 1/3 of the dics (scrapped one box as I overbored it a touch).

So I recon I could get at least another 10 from the remains of this disc.

What do folks consider a sensible clearance on the axle ?

Another source of good cast-iron is the base off an anglepoise lamp, the genuine ones. About 6" dia and an inch thick. I know 'cos I've just dropped one on my foot.

… but not a cheap source of cast-iron as genuine anglepoise lamps sell for fifty quid upwards.

… and my genuine Anglepoise lamp has a square base.

Michael The dull thud is probably more of a clunk, however a magnet is attracted so I'm going for cast iron

Neil There is a hole across one end for the sashcord. I've never come across one with a hole up the middle

Then you probably haven't found a lead one. I think an eye would be unreliable in lead.

As a small boy I built a "nuclear reactor" from an old metal tank with sash weights as control rods operated by string. If you lit a fire in the tank the whole thing warmed so was more realistic when sitting on the top 'controlling the thing" Somehow never go round to making a real one though. Happy days.

I can't see how that contributes to good axlebox design, but I enjoyed reading it

My genuine anglepoise hasn't got a base

I just have a few strategically placed 1/2" holes in my benchtop.

Mr Provins- thanks for the info, one genuine ,round base anglepoise going on sale, will not bother to paint it. Hard to match the genuine grey blue, like a washed out myford.

If you end up with discs with a hat shape, that raised bit made a rim for a flywheel.

I am based in Worthing and I have just bought a pair of Nova Discs. I only need one so I have one going free if anyone would like it!
