Hank mentioned to me that there may be an easier way to communicate the stuff we're discussing. Wed, 10 Feb 2010 07:06:30 GMT Dean http://groups.yahoo.com/group/atlas618lathe/message/4415 http://groups.yahoo.com/group/atlas618lathe/message/4415 Hi Bill; Glad if this does you some good. About 20% of what I do is in brass, and I keep a set of turning tools just for this, all completely flat on the top Wed, 10 Feb 2010 03:47:48 GMT Rudy Thompson http://groups.yahoo.com/group/atlas618lathe/message/4414 http://groups.yahoo.com/group/atlas618lathe/message/4414 Dean, I would like to say thanks for the help.. when the machine shop checked the spindle the chuck register was part of their checks, but the inside of the Tue, 09 Feb 2010 17:48:46 GMT n1ltv http://groups.yahoo.com/group/atlas618lathe/message/4413 http://groups.yahoo.com/group/atlas618lathe/message/4413 Lots of helpful questions, answers, and anecdotes here at Steve's website: http://www.janellestudio.com/metal/turning_brass.txt Tue, 09 Feb 2010 16:11:09 GMT n0cic http://groups.yahoo.com/group/atlas618lathe/message/4412 http://groups.yahoo.com/group/atlas618lathe/message/4412 Thanks for the info Dean, I did not know that I should not put some top rake on my cutting bits for brass. I will grind some new bits and try them.

I'll let you know how I make out. Thanks for taking the time to respond. I appreciate it.

Check the chuck register, the larger flat diameter directly behind the threads (on the spindle). With the chuck removed, check that Tue, 09 Feb 2010 05:36:30 GMT Rudy Thompson http://groups.yahoo.com/group/atlas618lathe/message/4409 http://groups.yahoo.com/group/atlas618lathe/message/4409 Dean, I am new to this hobby. There are two chucks that came with the lathe and at low speed I can see the run out on both. One is a 3 jaw (polish make) and Tue, 09 Feb 2010 03:47:47 GMT Uldis Stulpins http://groups.yahoo.com/group/atlas618lathe/message/4408 http://groups.yahoo.com/group/atlas618lathe/message/4408 Those "zero rake" bits will also work great on plastics, such as acrylic or rigid urethane, where otherwise, a standard bit may grab and shatter the material, Tue, 09 Feb 2010 03:19:58 GMT Dean http://groups.yahoo.com/group/atlas618lathe/message/4407 http://groups.yahoo.com/group/atlas618lathe/message/4407 Hi Rudy; How much runout do you have when you mount a ground test rod in the chuck and run it with a DTI? What kind of chuck. Three jaw? Any burrs on the Tue, 09 Feb 2010 03:12:49 GMT Dean http://groups.yahoo.com/group/atlas618lathe/message/4406 http://groups.yahoo.com/group/atlas618lathe/message/4406 The reason it wants to spin when drilling brass (specifically), is that commercial drill bits are not ground for brass. Just like for turning brass, drilling Tue, 09 Feb 2010 02:27:54 GMT Gary Brackney http://groups.yahoo.com/group/atlas618lathe/message/4405 http://groups.yahoo.com/group/atlas618lathe/message/4405 Another thing, use a little kerosene or tap magic when you drill brass as it is very gummy and wants to grab the drill bit. This will help you somewhat.

There's no place for the tang of the arbor, and the small size means the torque Tue, 09 Feb 2010 00:13:16 GMT n1ltv http://groups.yahoo.com/group/atlas618lathe/message/4402 http://groups.yahoo.com/group/atlas618lathe/message/4402 Alan, This ebay seller has them, but you have to buy a bag of 50 for $6.00 (including postage): http://stores.ebay.com/ToolSupply Hank
