So I get this call from a guy out of the blue. He got my name and number from a mutual friend. This guy bought a bunch of stuff from a racing team shop. The team is done. Well he bought barrels full of metal drops. So I went over and grab some but didn't even make a dent into his stash. I mainly grabbed 6061 and 4130 stuff and smidgen of 1018, 1045, and Delrin thrown in. I don't know if he would ship but PM me I you want to contact him.

Looks really good, Mark - have you chucked a piece of turned + ground in it and measured the runout yet?
I'm planning on an ER chuck for mine some day, but with a camlock spindle nose it could be a lot more complicated (and needs a piece of 6" round to start from...) - and I already have native collets* and drawtube for up to 7/8" by sixteenths, anything bigger goes in one of the 4-jaws...

* rare as rocking horse droppings, Holbrook collets :(

I chucked a part in the 1" collet to bore it and it ran within .0005" I'm happy.:grin:
 
Discovered this when I opened the breaker box on my new to me Doall saw.
I guess the PO discovered that a penny just wouldn't do the job. Then again, modern day pennies are mainly zinc, which won't conduct as much electricity. Wonder if anybody with an old-fashioned fuse box has done any research. My guess is that they'd be haunting coin dealers for the old ones. Maybe that's helping drive the price up :)
 
It looks to me like that wire bridging the fuse is around the same gauge as the wires leaving the fuseholders. Doesn't sound like a good idea.

When I was an engineer for a company building heavy trucks, we would sometimes use a fuse-link on wires coming directly from the battery for specific options. The link consisted of a 4" piece of wire connected between the battery terminal and the main wire that was 4 wire gauges smaller than the main wire. A #8 AWG wire would have a fuse-link that was #12 AWG. Just a little trivia to make your life complete.
 
Wire? Surely they could have used something more suitable, .308 Winchester might be a little short, .50 BMG perhaps?

After spending some down time in TX airports from the storms I was forced to look at art. Two pieces caught my eye and gave me an idea for my mistakes and projects gone wrong . At 500 a piece I might break even.

Nice, what is the tip, Looks almost like one of my small drill rods.
 
I made a scribe/scratch awl over the weekend out of C544 bronze, it has a reversible cutter so it can be safely stored. I took a bunch of video, now I just need to find the time to sit down and edit it.

Very pretty piece. You've made an heirloom.
