CNC Holders

Harold: You probably haven't seen the collets that the CNC guys are using these days. Suck them up tight and they go absolutely NOWHERE. Nikken started the ball rolling about 20 years ago and never looked back Granted, you don't see them in home shops because they don't fit in the R8 or similar smal...

Model Cannons and GOLF BALLS

STOP RIGHT NOW and consider what you are about to do. Shooting a steel ball is one thing, attempting to shoot a golf ball is quite another. Golf balls are flexible by design. When you hit them with pressure, they DEFORM. Put one reasonably snug in a cannon barrel, smack it from behind with pressure ...

Warpage

Warpage in cold rolled (and other) material is usually caused by an unequal removal of the 'skin' from the under lying material....orinternal stress from forming, like the duplex stainless steels that are so popular for certain applications today. typically, when turning, the removal is rather unifo...

The only things that seem to be selling are multi-axis swiss and multi-turret, twin spindle turn-mills....all that can make the more complex...

Enco Mill

While Enco makes good machines, this is not really something that you can push very hard...

It is something that is primarily sold in the Fatherland to trade schools (at least those are the folks purchasing our software to run them)....

Note the travels...LESS THAN 10".......

R-C

Steve.. You can pretty much write him out of the picture. Dan (Fender) was the last person that I know who was actually able to get something from him, and he had to DRIVE from Richmond VA to NJ to pick the stuff up after the better part of a year of trying to get him to answer the phone, respond to...

Collets

With large mills and heavy cuts, any mill can pull OUT of an R8 collet and ruin everything..work, table...collet..you name it. Other collets, such as those made by Nikken (as one example), once pulled up will NOT let the tool move...PERIOD....but you typically cannot get them in R8 variety. Set scre...

3/4" trucks

Not too warm on the idea of plastics. A set of trucks with a pair of 200# men sitting the car can cause quite a load and things of plastic may not be stiff enough to support the 'cattle'. Granted, a tender alone doesn't weigh all that much, but why lose 1/2 of your customer market by not making some...

Belts

long-term, it is just better to bite the bullet and put in a set of premium belts from a major manufacturer.

Mine on my lathe lasted me 30 years, so by that time it wouldn't hurt to pull the spindle out and clean things....

Old Machines can be a disaster

I couldn't agree with you more when you are comparing the machine capabilities as you are. Where I might express my concern is with older, non-supported machines, WHEN, not IF something dies in the control circuitry, you have a couple of tons of scrap iron on your hands. The older controls / machine...
