I use an Aloris BXA tool post holder on my Heavy 10, with great success.....up to now. I bought, and then discovered, that the BXA-22 Universal Turning and Boring Holder is too big, specifically too tall, to work with my lathe. The tool point is about 1/8" above center with the block down on the compound. I touched the holder with a file, and it seems pretty hard. Anyone ever machined down an Aloris tool holder?

They are hardened. You will have to use a surface grinder to modify it. 1/8 would not be a major weakening of the holder. 

BXA is a bit large for a 10k lathe. AXA would have been a better choice. 

AXA tool post is meant for lathes 9-12 inches

BXA tool post is meant for lathes 10-15 inches

Using a BXA puts your lathe at the low end of the size range. Clearly it has not been a major issue until now. 

Just 2 cents

        Joe Pie has a vid where he shows how to work that without modifying the tool post https://www.youtube.com/watch?v=4mxCvOOHWo4&ab_channel=JoePie  starts @ 6:30 . I fell asleep with the TV on youtube & woke up @ 4 in the morning to that  part .

Hi There,

I have modified a couple of Aloris tool holders using HSS.  In my case,
I had a couple BX1 tool holders that wouldn't fit the dovetail on my tool
post (an Aloris BXA).  I have a large 60° cutter and I made a couple of
light passes (about .003") to open up the dovetail to make it fit.

I had an occasion that I needed to lower the tool block and I just moved
the tool post on the compound so the dovetail section hung off the side
enough to allow the tool block to clear the top of the compound. 

Good Luck!

I’ve taken some off the tool shank to drop the cutter on centre on a couple of my favourite cutters, worked fine.
