Re: Turned solid bullets?

Gene,
Don Atkinson was interested in turned bullets for the .50 and may have a report for you in that regard. He has explored the possibility of machining them.

Re: .22 magnum rims

Tel, Years ago I gave considerable thought to making jacketed bullets. I spent a little time talking to Ackley about the idea of using spent .22 cartridges but he had an even better idea. He suggested drawing ¼" copper tubing to length. I went so far as to make a crude die, which I attached to a pow...

Re: Wrinkle paint/Paragon

Considering your statements, I'd have to conclude that tower type speakers are a result of applying a new technology based on this knowledge. I recall that McIntosh was selling some that were very narrow and tall, apparently an attempt at keeping the speakers somewhat in phase (or time), for lack of...

Re: Wrinkle paint/Paragon

Greg,
I'm having a little trouble understanding the concept. Do you really mean vertical in this instance? Seems to me that horizontal would make more sense, or is it just me? Could you further explain, please?
Thanks

Re: Rebending Brass (or bronze)

Nope! You sure didn't Rolly, just making sure he didn't do it hot. I totally agree with your annealing process first. While brass isn't a heat treatable material, the fact that they have been bent speaks volumes about the possibility of them having work hardened from the current state of offset. For...

Re: Rebending Brass (or bronze)

DO NOT HEAT THEM!

Brass and bronze are both hot short, which means if you work them in a hot condition they will crumble.
The only chance for success is to work them cold.

Re: Wrinkle paint

Hey Scott, That's an interesting report on the unintentional wrinkle paint job, though you've lost me with the talk about "3M rocker Schutz,and using my body Schutz gun". I have no clue what you're talking about, so if you have a moment, bring me up to speed. The rest makes sense, though it sure is ...

Re: Turning hardened O-1?

Hey Davey, A centerless grinder is a machine that grinds objects without the use of centers, thus the name. They are a production machine by nature, capable of producing literally thousands of part per hour and holding .000050" easily. A good example of a part that would lend itself to a centerless ...

Re: HERE are the pictures!

Very nicely done, Matt. Keep that exact concept in mind when you're grinding HSS toolbits for your lathe. They work wonders there, too. I couldn't help but notice that you commented that you took the pics with your scanner. That's the best close up camera a guy can ask for. Check out the little part...

Re: Wrinkle paint/Paragon

Hi Jerry, You said: I find JBL to have a different problem, the ones I have measured have a "leading" HF arrival, causing the brighter sound. That probably explains what I've always considered to be their "bright" sound. I've always said they seem to have a lot of "presence". (What ever that may mea...

Re: Firebrick for Metalcasting Propane Furnace

Hi Phil, I thought I was going to give you an easy route, but things have changed significantly since my last inquiry. I sold the gold refining business in '94 and have not kept current. Turns out the entire refractory industry has undergone some drastic changes, including the buyout of A.P. Green, ...
