Re: Thread Milling

Thanks guys. So Glen, I'm guessing that you cut the OD to size and then mill from the top to the bottom and the multitooth tool has the correct taper so the taper widens as it progresses down the shaft? Sorry for the silly questions but what you have shown is really cool! I'm guessing you couldn't d...

Re: Thread Milling

Interesting subject! Just curious, I'm assuming that the process for pipe threads would be a little different than the process used for a straight thread. How do you account for the taper? My old Heidenhain controller will do helical interpolation so I'm anxious to get a cutter and try it out! Thank...

Re: Model trains

A few years back I bought a Bachmann G scale train from Hobby Lobby, as Mr. Ron suggested, to go under the tree. it was a really nice steam train, for not a lot of money, and being big G scale worked very well under the tree until it occasionally came under attack by the family cat. If you can't get...

Re: PM1236 arrived

Congrats! I have the same machine and it has served me well. I had a few minor problems initially but those were all resolved quickly by PM. I have since converted mine to a 3ph motor and VFD and haven't looked back!

Re: advice/opinions on a new x45 clone

Hi Dave, I have the predecessor of the PM-932 and it has served my needs pretty well so far. Mine does not have a motor to move the head but that would be a great option. The head is pretty heavy and cranking it up and down gets old really fast. Power down on the quill is a really nice feature for b...

Re: Drill chuck removal with wedges

Certainly no expert but I've been successful a couple of times now by placing the arbor in about a 3' piece of thick walled PVC pipe with the chuck sticking out the top and then bounced the open end of the pipe on a concrete floor. Arbor popped right out but maybe I was just lucky.
Regards,
Les

Re: You must be bored when??

ctwo, I actually considered building a frequency to voltage circuit for the old Sun tach but the meter movement itself was shot. SABToolmaster, I appreciate the "you know you're bored" list consideration. It was actually a fun little project and most folks that see it say "what the h*** is that?" Les

Re: You must be bored when??

I like your tach! I installed a VFD on my lathe and find my tach to be very useful. I bought a tachulator from LMS oldtachrpm.jpg but it just didn't look right so I gutted an old Sun tach that I had in the junk box sun.jpg and now I have a proper looking tach :D newtachrpm.jpg Best regards, Les

Re: Tool grinder

Hi Howardd, I bought a grinder from HF that looks identical and suspect it is. Mine came with green wheels that are supposedly meant for carbide but in reality were total crap. Perhaps the wheels on the enco unit are different but I would certainly check that out. I was able to find an aluminum oxid...

Re: Some advice please

No worries at all Marv. I appreciate and read your posts on this forum and others with great interest. My math is so seldom correct I just had to jump back in there :D I guess the old school (least common denominator) way for 1/20 - 1/24 would be 6/120 - 5/120 = 1/120. Anyway, thanks for a great pos...

Re: Some advice please

Ok Marv,

Guess my calculator is broke :D

1/20 (0.05) - 1/24 (0.0416666666666667) = 0.00833333333333334 so 1/0.00833333333333334 would be the equivalent of 120 tpi. not correct? Where did I run amok?

Regards,

Les
