Well, I failed in properly formating the comparative numbers. I always did need a secretary to clean up after me. I'm not going to attempt to do it again, but...
I decided to do the quick change tool mod off Hoss' site http://www.hossmachine.info/projects_7.html Really I only want the quick release and repeatable Z...
blue the OD of the holder and put it in and out a few times to see where the contact is. if the blue is uniformly contacting, you are ready for the next step....
I can never out-advise Dave... One thing I didn't hear mention of was runout testing on the lathe chuck. Most of them have at least a bit so no matter which...
... <snip> How close is the fit of the end-mill in the holder? I use a collet for end mills smaller than 3/8 because the set screws in the holder can push...
I looked at the Hoss site again. You can make the tool holders a bit long on the shank end. rough the OD on both ends to get it within two final passes. 10-20...
Not sure im following your post but ... If I'm understanding you you're saying to turn down the shank to 10-20 tho over. Drill/ream insert endmill into new...
I will let you know how the results go. I destroyed my carbide boring bar the first time I tried this instead of reaming... Not sure I had the boring bar in...
I have tested the collet in my lathe C3 If I remember correctly and it seems to be junk, If I turn down a piece test it, its concentric. If I just loosen the...
I am using 3/8 shank endmills. The hole is pretty darn close. My ground pin set -.0005 a 374 will fit but a .375 won't... The 3/8 endmill fits perfect tho. The...
Can somebody send the MiniMillUsersGuide.pdf to me off list? Here's my address: jagness@... I don't know if there's a problem with the Little Machine...
Try here: both Grizzly and LMS manuals, plus some more stuff that might be of interest : http://thomasuchison.wikispaces.com/CNC+and++Machining+References...
Ok I finally got some shop time in. I made 3 holders. No success. The 3rd tool holder I think is the important one here. Being the 3rd tool holder I really...
I guess we can assume that there are no burrs or chips or any dust on any part or your set-up. test your collet chuck for run-out before you put in a collet....
When you mount it in your lathe there is the possibility of runout, be it from the self-centering chuck, a collet, or even poorly centering it in 4-jaw chuck. ...
I cut 3/4 shank on lathe. Flip it and put it in collet. Under drill the hole. This whole is not perfect because of the collet and using a drill but I mount in...
Thanks again for the reply Dave. I cleaned the holder and the spindle with my fingertips and did not feel or see anything in there. I will take my compressor...
At a high level, Dave and John are giving you similar advice -- you can't really trust anything so take the variability out of the picture. If you do every...
the an R8 collet is held on the taper at the face, and on the ground OD on the tail. the R8 is 4 inches OAL, so the back is deep in to the machine. if the...
Maybe instead of using somebody else's R8 collet you could just make your own: http://www.shars.com/product_categories/view/4081206/R8_Emergency_Collet So...
Hi all, with all the talk about pulley swap-outs, one of the things I have pretty far down the list is to replace the MT spindle with an R8. looking at the LMS...
Why can't the OD be turned and one end faced. Chuck up on the OD, preferably with 4 jaw. Now face the end and machine the 3/4" OD shaft, center drill, drill...
I like the site too :) I hadn't seen it before and will be reading over it and all his projects. You have giving me lots to think about not to mention a great...
Thanks, those are pretty neat I think I will order some for later. I have plans on ordering the real TTS collet from Tormach and im sure that will be accurate....
It seems that easy but I have been trying and its not coming out right. 1. I can't seem to ream a hole using the vice on the mill to save my life. So I have to...
Wow Dave some interesting results... 1st thanks I never noticed the other end was a ground surface I thought the taper was the only thing aligning things. What...
Identifying the problem is the hardest part. It does look like you will need to make adjustments. in the mean time, to get work done...... chuck up the reamer...
