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, ...

Re: Bad link

Thanks, Don. In my haste I didn't check to see what I had posted was proper. Missed it somehow!

Re: Brand name instruments...hey Harold...

Hey Jeff, Hope no one takes this the wrong way, it's just a statement about me and how I work, but I have absolutely no interest in any of the electronic tools, and I don't own any of them as a result. In spite of the fact that they may even be superior, I consider the use of the manual machines and...

Re: Brand name instruments

Hi Bob, I started in the trade in '57 and made it a policy to buy, almost exclusively, Starrett. I'm not saying they're the best, but they are of good quality and will serve me to my dying days, at which time they will still have good value because they have received outstanding care. I have microme...

Re: Turning hardened O-1?

Davey, I've read all the posts thus far. If none of them work, and you find you need to grind these shafts, if they are straight, no shoulders, a centerless grinder would do them beautifully. If you have a number of them to do, it would be the best possible way to handle them. You could minimize the...

Re: Firebrick for Metalcasting Propane Furnace

Steve, Firebrick is available made from various refractory materials, so there's a brick out there that will withstand pretty much anything you can throw at it. Stacking them is acceptable, and you can even do it without any kind of bonding agent if desired, especially if they are restrained in a co...

Re: Wrinkle paint

I'm moving rather slowly getting this thing finished, but I'll post a picture when that magic day comes, along with a "before" shot. Probably a couple weeks away. Thanks for your interest! [img]/ubb/images/graemlins/smile.gif"%20alt="[/img]

Re: Wrinkle paint/Paragon

Hey Jerry, Interesting comments on the Bozak system. I always sensed a huge difference in the sound, but attributed it to the softness of the multiple speakers as compared to the brightness of JBL's horns. Now I have to wonder if what I was hearing is what you suggest. I've never made stereo systems...

Re: List of steels and properties.

I don't know of such a list. I use Jorgensen's stock book, but I also have a basic idea of what I'm looking for and I'm familiar with materials to some degree. If you're not familiar with them, it could prove a little difficult to make intelligent choices. To my knowledge, EMJ no longer publishes a ...

Re: Tap making project completed

Dean, Same process. When you cut the flute, where the ball end mill is located, the diameter of the end mill, or how deep you make the cut all effect rake angle. Thread FORM is not effected. That is determined by the shape of the teeth, which you control by cutting the thread with a properly formed ...

Re: Tap making project completed

Don, Very nice job! You commented on having to back the tap off to clear chips. As we all know, that's a function of how straight flute taps work, and unless you were tapping a through hole in cast iron or leaded brass, you shouldn't expect the tap to perform any way but how it did. The fact that it...
