Well, it's an excellent plan. I have 12 Cox cylinders + pistons + glow plugs, but no 17/32" - 40 taps or dies. I have a 1/2" - 40 tap - close, but no go. I tried twisting (with a big enough wrench) the threads into ali, brass and steel. Ali and brass mangled the thread, and steel mangled the...

If it's 50 years old, try first electrolytic capacitors, i.e. change (for a new - really new, not some old stock) everything you can find. Change also the diodes for a newer and more "robust" types.

That sure is a nice machine! Their PS: the valve system looks very simple and interesting (IOE ?) a nice project for the machinists! Yes, Sir, if ever you would make drawings, I would be interested.

A serious lathe. Very nice!

Nambé (/nɑːmˈbeɪ/[1]) is an eight-metal alloy whose major component is aluminum. It was developed in 1953 by Martin Eden, a former metallurgist at the Los Alamos National Laboratory. The alloy is exclusively produced by the Nambé Mills, Inc., which was founded in 1951 near...

Hi Gus, I think 180 Rpm is a bit too fast. My feed screws (X and Y) are M14 x 2, meaning one turn is 2 mm (fwd or rev). 180 Rpm is 3 turns/sec., it really zooms at that speed. It's rather difficult to wind slowly, 1/3 - 1/2 speed it's rather weak of a torque, and if you're not very careful, it...

I think a reed switch works ok, unless the frequency is rather slow. 5 sparks/sec is only 300 rpm. There's no way to run a F1 motor at <10000 rpm with a reed. At 50 sparks/sec, that's 3000 rpm - no way. But you could try :-)

Lard in Portuguese is "Banha de porco". Several varieties, some are almost odorless, some are definitely smelling bacon. I heard McDonalds contains some 6-7% lard, the rest is vegetable oil, and the French fries seem tastier with some lard.

The opposed-piston diesels were quite powerful, like Jumo and Deltic. The really big engines were marine, the Doxford shipyards. It began at abt. First World War, and the last vessel and engine was built in 1980. 76cm cylinder bores... :eek:

Hi Gus, the Tormek sharpener is top quality, Swedish and pricey, but there's also a German Scheppach "wet whetstoner", at http://www.scheppach.com/en/produkte/einzelansicht/products/nass-schleifmaschine-tiger-2500/backPID/werkstatt.html?cHash=cc0c7f0e79

Cherry Hill (nee Hinds) is aged 81, and IMHO, is still working his Cowells 90 CW lathe, sometimes.

The www.exair.com and www.vortexitalia.com sells many different Hilsch tubes. I had one Exair's Mini Cooler, tried to cool sewing machine needles. Thick needles and thick materials, with >4000 rpm, will melt synthetic (plastic) threads, and of course it's not advisable. And the needle is quite...
