AGREED!

Uh....I can't find it. but here's a router bit box I made at the same time. The two router bits I made before 1976, to make the slats for a roll top desk.

A friend suggested he needed a way to put reeding on the edge of a cabinet he was making, I'm making a bit now (Pix when its done) for that.
I was working in a boat plant, had lots of scraps of teak and mahogany. Here's one, http://www.yachtworld.com/boats/197...Fort-Lauderdale/FL/United-States#.WIAbExsrKCo

I built the wood colored parts above the deck. Deckhouse and pilot house. On this boat.

WOW, thats incredible work Tom.

Would the CO2 boiling in the acetone put out the fire??? I think some experimentation is in order.....

This reminds me of my experience @ age 12. Mr Wizzard of TV fame showed burning steel wool in oxygen. Since my Dad had an oxyacetylene torch I decided to repeat the experiment. I wondered what it would look like if I added some acetylene to the mix. I didn't have time to see the results but I decided not to try it again ! Six months later a pumpkin seed size chunk of vinegar bottle was surgically removed from my right hand.

Got some scrap PVC "tees" from a guy at work...being the packrat I am, I took them and said I'd find a use for them.
Support for my barrel...will let me apply bluing solution without having to worry about support. Parts in the tray below the barrel were just finished.

I still have a teak covered drill index I built for a specific job in the late '60s. Hope someone will appreciate it down the road.

Funny you should mention teak. I just made a pair of covers for my mill table out of a piece of teak veneered masonite. Makes clean up a lot easier.

That's a gorgeous boat Tom, very nice work you did on her. Mike

Made some brass wheels. They will have bearing inserted and be used to made an arrow spinner for a friend.
Considering it was just some scrap brass/bronze pieces he brought round (valve bodies, a couple of failed regulators, etc) and we melted down into a bar last weekend I'm pretty happy with how they turned out.

Thanks to the generosity of Scruffy and his Christmas Give-away, I now have a surplus of R8 Collets. He sent me 21 used, rusty but not worn out collets. Between 1/8 and 7/8 there are 11 of them including #3 and #7 drill, and couple of 1/16, a couple of 1/8, a couple of 1/32s and all the 1/4 and all but one 1/8. plus a fair number of duplicates.

But what am I going to do with them!

I'm working on a router bit, want to cut four flutes on it. If only I had a 3/4" 5C collet for my Hex/Square blocks. Wait a minnit, I've got R8 collets just lying around. Why don't they make Hex/Square blocks for R8 collets!.

Seems I ought to be able to do something....if I made an adapter for the 5C to R8 end, and an adapter for the tail end, and sucked the collet in with a 7/16-20 socket head cap screw, could I then use the Square block to cut the flutes on my router bit? Sure, why not!!

So here's my results.



I don't have a grinder so I had to do the best I could with my Atlas/Clausing MK2 6 20 lathe. The angles are good enough, even though they may not be spot on, they are concentric.



Not a very good picture, but you get the idea. Here it is assembled.



Now I can cut my flutes and give the beading cutter to my buddy. Well, I'll harden and draw it, and do a bit of hand relief on the cutters. But it should be good to go. Bearing and all.

If there's a bunch of interest, I'll work up a print of the parts and discussion on how I proceeded, probably not including the glitches I had to overcome.

Made this little exercise a few days back and sent it to a family friend who's a retired machinist/engineer:



I'm pretty happy with how the knurling came out. The seam in the main piece is pretty much invisible.
