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?

Buy it or someone else might buy it and impose charges on you!

Obviously not used by engineers!

I will work it out in cad  for you. I make it 75.12mm diameter.

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

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!

Anyone know how to wire this dynamo. It has 3 terminals Plus, Minus and an unmarked one in the middle.dynamo

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

Use two with offset pulleys!

One of our local council dumps has twice burnt down due to piles of Lithium Ion batteries catching fire!

Not sure. I will have a look at the weekend

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

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.

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.

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

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

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