Can anyone help me out with how to remove this Beaver quick change boring head adaptor #64 from the 3" Criterion boring head. I tried with a spanner I made but it did not budge. I don't know if it's left or right hand threaded. I haven't heated it or used a pipe wrench on it not wanting to damage it. I was unable to find any info on line. The head is in nice shape, so I would like to make use of it if possible. Any help would really be appreciated. Thanks, Charlie.ABC6A76B-5C16-4FA3-8050-77596FA88B79.jpeg9491DA47-9E00-4F1A-963F-F26C5CDFC944.jpeg695D1B17-550A-496E-8173-9CFA553D44E7.jpeg986EFE92-9C93-4CD6-819B-502EA7FDE61D.jpeg5F6B88F1-256B-4731-912E-FD6474EB2B0F.jpeg

It looks like it about the right size to use one of the half-round wrenches with a single tooth on the end. Sorry, Don't know the proper name for them. But, they're the type used on ER-32 collets.

It should be right hand threads so it tightens spinning normally.

Thanks for your reply. I had a 3' bar on the spanner and went right first and then left and it didn't move. With the head locked in my vise I was afraid of damaging it. The hole in the shank in some way may play a part in some way. After trying with the spanner and the bar It was tempting to use heat but I didn't. I have to wonder why it's called a quick change adaptor.

Thanks for your reply, I have tried with a spanner with no luck. Thanks.
 
I agree that it's probably threaded on with a RH thread. My guess (and that's all it is) is that the "quick change" part is what that stud goes into. I'd start by tearing apart the boring head - they're not complicated. Remove all the 'gib' screws, and start backing out the adjustment screw. Once removed you might (might!) have a view of the other end of that adapter. That will at least give you somewhere to shoot some penetrating oil as well as possibly confirming the thread hypothesis.

Hi, Thanks, I went through that and didn't see anything, I was hoping to find some sort of retaining bolt but there was nothing I could see that was holding the head. I didn't want to heat the adaptor but I think I'm going to have to. I just don't want to hold the head in a vise. When I did use the vise the first attempt I used delrin blocks to avoid any damage to the head. Thanks again.
