Re: [Emc-users] Deep slot chip removal

[dave engvall]

With an open machine I tend to us air rf vacuum to extract chips. One 
needs enough air movement to get turbulence for effective chip removal. 
I tend to start pockets, etc with a drill to within .02 of full depth. 
I've also drilled a pattern of holes to extract major volumes of 
material from pockets. However, just getting a good starting hole with a 
drill and then continuing with a mill is a smoother process.  In 
desperation mode blow air and catch the chips with vacuum much like a 
dentist does.

Flood coolant, air blowing, or vacuum. Or pre-drill a bunch of holes to almost 
finished depth to remove the majority of the waste before milling.

Milling a deep pocket spiral down work great first turn but after a
while torque is not enough and mill stop. Suspect it is because mill
have to cut old chips in addition to machining part.

Maybe it is a good idea to use drill bit a little bit smaller than
slot?

Re: [Emc-users] ? cutting a square carbon fiber tube ?

[Todd Zuercher]

The Craftsman version (exact same saw I think) costs a little less than the 
Stanly.

[EXTERNAL EMAIL] Be sure links are safe.

The Stanley 20-800 should do the job. Apparently Home Despot has discontinued 
selling that one, or any other hand powered precision miter box / saw. It's 
either the cheap plastic crap that can't cut a decent angle or the big power 
circular saws that cut out huge kerfs and are no good for cutting small or 
delicate materials.

But the Stanley 20-800 and similar from that and other brands are available 
many other places.

Use a fine-tooth hack saw.  It is easier to cut a fiber tube than a same-size 
hardwood dowel or same-size steel tube.
