Re: Logging Out

Gene,
Are you logging out when you leave the site?? If so, don't. Just close it like you would anything else you look at. That way it remembers you, or at least it does when I close out that way.

Hope that helps~

Re: Crucibles

Russ, An interesting question. In my refining years, one of the small furnaces I used for melting pure silver to cast ingots (these were small ingots, nothing larger than 20 troy ounces) was a little electric furnace that used a pure graphite crucible. The crucible, inside, and anywhere it had littl...

Re: First Casting Project

Bob, I get the idea you made the pattern. Congratulations on such a beautiful job. I've made just a hand full of patterns over the years and find that part of a project very rewarding.

Re: Refractories have a shelf life but..........

Yep! What Roy said. [img]/ubb/images/graemlins/smile.gif"%20alt="[/img] A few years ago I had a partial bag left after building a small furnace. Some time later when I tried a little to see if it was still good, it failed to harden at all. They're not joking when they say this stuff has a shelf life...

Re: Seeding the forum with casting Do's and Don't's

Orrin, I applaud your fine contribution to this subject, but fear both of us are trying to teach a pig to sing. I've given a good shot to passing along to the readers the good and useful knowledge I gained by my many years in the shop, but there's that small outspoken element in almost every group t...

Re: Reciprocating Hacksaw

Hey Joe,
I don't know anything about the saw, but it sure will be a fun project getting it running again. A hack saw has certain advantages over band saws. I think you'll really appreciate having it. That dude must be at least 75 years old!

Re: Casting Ruler

Hey Cap'n, Yeah, shrink rules are still available. Starrett sells them and I'm sure others do as well. I bouught two of them a few years ago, one a Starrett C370, 1/8"/ft. shrink and the other a Starrett C375, 3/16"/ft.. These rules are a nice satin chrome finish and very easy to read. Current catal...

Re: I can see it on an arbor type milling cutter

In regards to the end of an end mill, any end mill, the profile of the cut is generated by the very outer tip of the end mill when it is properly sharpened. That means that you get a full diameter flat surface, but only when you move along the face of the piece being machined. When plunge cutting wi...

Re: True to an extent

I don't think passing on them because they are left handed is a reason, either. There's room for most any kind of cutter in your shop when the price is right. If you bought sharp end mills that have not been sharpened until the rake angle and chip clearance is reduced, left or right hand makes littl...

Re: Here you go Roy

Doug, Thanks for the pictures. I was so caught up with the rake angle of the flutes I neglected to think of the effect of the left hand helix on the ends. Yes, there is negative rake where the end of the end mill is concerened. I stand corrected. HSS end mills that have a negative rake on the END wi...

Re: Millrite quill falls under its own weight...

Sounds like it went fine, Mark. Good to hear it was a simple fix. I think you'll like having the quill set light. I keep my Bridgeport well oiled so it stays nice and free, and have never changed the setting, it's as it came from the factory. That's how they set them up and I'm very happy with how i...
