Thread: Limiting pressure to a gauge
16/10/2019 21:39:22

I am rebuilding a 1910 5 litre petrol engine. On start up the oil pressure peaks at 70 psi but the running pressure is 15 psi. I need to limit the pressure reaching the gauge on start up as the gauge only reads to 30 psi?

Make sure the black bar has enough material to machine to size.

Thread: Alternative metal sources?

When I worked in the engineering dept of a major high street bank, I managed to get the most valuable thing possible in the company. A letter from a director authorising me to take anything I liked from the scrap skips! As I was responsible for what went into the skips this was like winning the lottery!

I buy brass, bronze and ali from my local scrap merchant at very reasonable prices.

Where is it? Just what we're all after!

Always worth asking around, but my local scrap merchant is only interested in buying metal, not selling it in small quantities. 30 years ago you could wander around, dismantle cars for parts, explore the bins and offer cash for interesting surplus equipment. Now the site is surrounded by razor wire and patrolled by aggressive dogs. It's not set up to deal with casual purchasers. Not a particularly good source of hobby metal either - too few manufacturing offcuts in my part of the world alas.

Thread: Hand or Machine Reamers?

Machine reamers can cut over size if everything isn't square.

Vintage Engineer - do you have any pictures of the connectors on the back of your switch on your 1914 Peugeot? One of the things we are doing on the 1926 machine is replacing the perished zinc die castings of the housing with machined aluminum ones. The originals have completely disintegrated by expanding internally and crumbling. As this happened the electrical connections fell out and were lost. We do plan to replace the connectors with bronze conductor parts and modern plastic insulators but would like to know what the originals looked like. Thanks again.

I have a 1914 Peugeot! Redsetter is correct on all accounts!

Thread: Whitesmiths Shop
29/09/2019 21:56:17

Yes as a retired blacksmith I once had a long discussion with a black gentleman as why I wasn't a whitesmith! Whitesmiths work with"white" metals, eg, tin, zinc, pewter. and lead.

Thread: Boiler build abandoned !

I use oxy propane for silver soldering and never have a problem. You can even unsolder joints. High localised heat is the trick to silver soldering.

I run a blown Lotus 7 and inject large doses of water and methanol when on full boost. This cause the incoming charge be cooler so produces more power.

I would cut down a tap and tap them, then fit grub screws.

Setting over the topslide in a production workshop would get you the sack!

Thread: Black Bar

Be very careful with mild steel black bar. This is normally recycled steel and full of all sorts of crap!
