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. :-)

At school we have two Rockwell vert bandsaws, one set up at high speed and a coarse tooth blade for aluminum, the other slow and a fine tooth blade for steel,. They both have rubber tires on the wheels and have been there running like that for well over the 16 years I've been there. We use 1/2"...

The "Liquid Nails Extreme Heavy Duty" version and the Locktite brand "Power Grab" both seem to good for their intended use. I did a comparison test while putting some wood trim in a camping trailer. Wood to fiberglass and wood to wood. So far both are holding OK. If anyone is int...
