Anyone who doesn't tell you where they are, isn't serious about wanting help.

Re: Need to drill 1/2 sphere hole in aluminium and/or graphite - 1/2" - 2" diameter

You'll need a lathe for sure and a "radius turner" . I've done this many times. It's even possible to make the hemisphere a bit deeper than the radius. The tool bit needs to be a bit different than the common one but it's no great problem . I'll be happy to send you some pix if wanted. ......

Re: Matching a taper

Yes I can BUT the compound on the lathes I have access to are very suitable to do this on. First off they have nearly 5 inches of travel and a straight side that a dial indicator can follow. So I made a fixture that sits on the ways and measures how far the side of the compound moves while moving th...

Re: Break-top Revolver hinge

After googling " throne of a mariner's astrolabe" I don't see any place where that sort of joint is needed. I am wondering if the revolver joint is "built-up". A friend of 30+ years ago had a revolver like that but I wasn't into machining then so it never would have occurred to m...

Re: Cutting aluminum on a band saw

It also helps a LOT to use one of the lubricant sticks on the blade when cutting Aluminum. The one I'm using is white and in a tube like caulk comes in touch it to both sides of the blade while running long enough to allow the blade to go around a couple times. For long cuts touch it again after a c...

Re: Unidentified taps

I have a neat tool called a Thread Detective. Actually, I have two. One metric, and one imperial. It's just a short cable with a bunch of fittings in various thread sizes. One side of each fitting is male, and the other is female. When you have a mystery fastener, you just see which fitting it like...

Thanks!

It took me so long to reply because we went down to our property. I bought a chainsaw and cleared a bit at the spot we chose to build on. I haven't had a chainsaw in my hands in OVER 50 years!

Then be careful, VERY careful, with it. :-)
