Re: 1911 Project

Keep posting Glenn.
I've been thinking of buying a kit....or at least the parts, to build one.
I only have three 1911's(Combat Commanders count too)....and three can't be enough.

Re: Dead 3/4 hp motor - starter capacitor?

I've had a lot of caps go bad, but always got a hum or a growl out of the motor when trying to start them. Very often, they turn a bit, but won't gain RPM. And most, can start & run, with a bit of assistance. My 8" grinder capacitor went bad, and until I got a replacement, I would give it some help ...

Re: Steel plate identification

Mystery metal ya have there.....
If you can machine it, and weld it, doesn't really matter much in the grand scheme of things.

Re: Steel plate identification

You can weld AR quite successfully, should you be making a weldment of some kind out of the plate.
You just need some preheat....and 1/2" plate doesn't take much.

Re: Steel plate identification

Well, I picked up another unmarked piece of 1/2" plate from the scrap yard today. They shot their gun at it for me (learned a new acronym today... I think is was a LIBS Laser-Induced Breakdown Spectroscopy instead of XRF). Unfortunately it didn't give an ANSI grade, said the new plate was "0.5CrMo"...

Re: Steel plate identification

Thanks for the pics and machining tips Bill. Tough stuff for sure. I might hang onto what I have until or in case something comes up to best suit it's strong points. LOL, in other words for now I'll side step it's tool eating habits. :mrgreen: A whole lot of our mill parts got sent out to specialty...

Re: Steel plate identification

That's where we used the most Pete......buckets & truck boxes. Quite a bit in the mill though, and that's where it got more difficult, as the parts required more drilling & machining, than just preheating and welding like for a mucker bucket. Here's some anvil plates I made for a hammer mill. I did ...

I'd say the beers are cheap, but I think it cost me 4 cents on resin. Of course I never count my time and effort or else this would be a money losing hobby!
I'm already ahead on the resin. I bought him a bunch of different colors last Christmas!

Re: Caliper battery covers

Doesn't matter what caliper others like. I think it's cool you can make things like those covers, with your 3-D printer! :)
I will keep that in mind, next time I need something like that, that has gone MIA. My son has a 3-D printer. I suppose I will have to buy the beer.....

Re: Steel plate identification

Hmmm... interesting. I knew Hi-Roc/etc. straight flute carbide drills are used for hardened plate, but I didn't know HSS could be used on AR. I don't think it is work hardening as the chip flow is consistent (until the bit breaks down) and I tried high and low speeds drenched in cutting oil. Didn't...

Re: Steel plate identification

AR400 drills & taps well with HSS. AR500 is at the upper end of hardness of what you can drill & tap with HSS. Any AR plate, can work harden, like stainless steels can, when you drill. I use speeds closer to 304 & 316 rather than A36 speeds when drilling. Flood cooling is the way to go too. Never bo...
