Re: Things they dont tell ya when you start casting. :)

There are lots of good books on foundry practice, if you want to go in serious depth get a copy of Campbell's "Complete Casting Handbook". He's the inventor of the Cosworth casting process. A friend and I have done a bit of foundry work with aluminum. The parts have been more complicated, like the a...

Re: MSC killing off ENCO

I just placed an order from http://www.latheinserts.com Curtis (exkenna at PM) is a good guy and he'll do right by you. He set me up with holders and inserts when I got my Mori lathe. A lot of people are very happy with his "Ripper" Korloy insert end mills which appear to not be too demanding on HP...

Casting an air-cooled motorcycle cylinder

My racing and foundry pal Jeff has put up a long/detailed/photo-heavy thread at Alloy Avenue about making the patterns/molds and then casting a new cylinder for his Kawasaki 175cc two-stroke vintage road racer: http://www.alloyavenue.com/vb/showthread.php?11802-Air-cooled-2-cycle-motorcycle-racing-c...

Prevention and control of distortion in arc welding

https://www.youtube.com/watch?v=2vuGlcbDwKY

Here's an old instructional film from the Lincoln Welding Foundation done by Disney Studios that discusses shrinkage/distortion in welding and how to deal with it. I thought it was well done and informative.

cheers,

Re: Manual to CNC Conversion Questions

I've got a feedrate overide knob on my control too -- but it doesn't provide any "feel" feedback as you'll get when cranking a handle manually. I think that a manual machinist is likely to depend on that type of feedback just as much as the visible/audible feedback, so if you take it away the operat...

Re: Manual to CNC Conversion Questions

To elaborate on what Richard says, you are probably better off starting with a dead control "made for CNC" machine and retrofitting the control. You'll save a lot of time and quite possibly money and have a more suitable machine. It will come with ballscrews, motors, mounts, an oiling system that is...

Re: China vs Taiwan quality

Ron, my original 10x24 bench lathe was a Select that I bought new about 1981, and it is serving a friend as his first lathe today. It seemed very much more "light industrial" than hobbyist, and at $1700 or so back then it isn't surprising. To get something comparable in the small lathes it looks lik...

Re: Which miller Tig to get?

Everyone have their lemons. Miller is not immune just like lincoln or anyother brand out there. I'm happy with the 250DX, my post was to illustrate how expensive it can be if one of the new "computerized" welders breaks down (and the 250DX is still a transformer machine and has less electronics tha...

Re: Which miller Tig to get?

I bought a new Miller 250 Synchrowave and it seems very nice (but I'm not an ace weldor). A friend just replaced his 200 Synchrowave with a 350 Dynasty inverter and is thrilled at the improvement (he welds a lot, both aluminum and thin steel/stainless sheet). One thing to keep in mind is that these ...

shows the manufacturing, inspection and assembly of parts for a
500 Moto Guzzi single engine.

Re: CNC Threading, this time on the mill

The makers of thread mills often have sample programs for using them on their websites. Google is your friend!

Re: Reverse engineering & milling of car suspension part

If you decide to use aluminum keep in mind that it has about 1/3 the stiffness, size for size, as steel and you wouldn't want to duplicate the part but rather redesign it for the different material. I have no idea what steel the OEM part is made from, but if it didn't need to be welded I'd probably ...
