Excessive wear on collars holding bits?

[hetzerguitars]

As you may have seen in this thread... http://www.carvewright.com/forum/showthread.php?t=6121 I think I know why I have 90% of my problems. The head was loose. Well, I tightened it up. But I have another problem. After doing a job (over 15 mins or so) the bits keep coming loose. Not from the collar (for lack of a better term) from the heads collet.

I noticed that the collar has excessive wear, so I removed the bit and put it in a new collar. And after about 15 mins, it too comes loose in the head. When I removed the bit (in the new collar) it too looks wore. Is this normal?

It's so loose by the time it gets to the end, I can put my finger on it and wiggle it around. And my project it ruined. I can removed the bit, and reload it and it will stay for 5 or 10 mins but any longer and it will come loose.

Sorry for not knowing the actual term, I am calling the thing holding the bit the collar, and the thing holding the collar the collet. The collet is on the head that spins. If there is a correct term please let me know.

P.S. No that's not blood that's red stain on my fingers. :-)

“The CarveWright creators are former NASA robotics engineers, and lifelong woodworkers, who saw the need for innovation in woodworking tools.” The preceding is from the LHR web site. I don’t know, but it makes me wonder!

The thing holding the bit is called a bit adapter.
Now, if I may ask. What are you trying to carve?
I've never seen that type of residue on the adapter from carving wood.

The BB Marks are the key that all is not well.... As soon as you first see the BB marks change the QC as it will now damage a new bit holder in as little as 30 min. Then you end up buying a QC and a few bit holders.


There has been a bunch posted about this topic.


The BB marks are like finding a flat tire on your car. The pictures posted by you are like driving on that flat tire 500 miles, pretty ugly.....

If you don't know what to watch for then you don't know.... Posting your pictures is a GREAT LEARNING TOOL for all of us.

Please don't feel bad, we all learn from others. This is a place to learn. I too destroyed 2 new bit holders in a short time having to buy a QC and 3 new holders.


Good Luck,

Jim, the wear you are seeing is not normal. Your chuck was likely damaged bu the loose Z-truck. I have been trying to reach you by PM to try and help get this resolved for you (click on 'Private Messages' in the top right corner of the screen under your name)

Well that sucks. Especially since in a prior post I used loctite on the end. I guess I will need to send the whole thing back? Wow, that really sucks. I hope I don't get stuck with $100 in shipping again.

A Heat Gun can loosen the blue locktite so you can remove the QC. It's also easier with the RJustice tools too.
