Hi all - Newbie here- my second post.

I want to replace my lantern toolpost on my 56TH 10F ATLAS. Probably too late to ask this question since I already received an AXA from CDCO this week, but can this be made to fit my 10" ATLAS? The T-nut is way too big for my machine. I've already gotten a 1/2"X 4" grade 5 bolt locally to replace the 9/16" , and if I add a 1/8" spacer under the toolpost it will swivel without hitting the top of the slide. I plan to cut down the head of the new 1/2 X 4" bolt to fit my existing t-nut(the one that came with the lathe), and it looks like it will work. A little sloppy in the holder bore, but I can add a shim to make the 1/2" bolt snug in the bore, if that's a problem. I'd just like to know if I am going to spend the time to make a new hold-down bolt, only to find out later that there is some other problem with this set up. (Maybe the tool holders locate too high or too low to be used correctly?) Should I just bite the bullet and return it to CDCO and buy something else? I don't want to fiddle around modifying this a couple of weeks, then find out I can't return this one because it's beyond 30 days.

Am I barking up the wrong tree, or is this just normal for adding a QCTP? I'd love to be able to make this work. I've noticed in many ads for mini lathes that the t-nut would have to be fitted. If that's what it is - no problem. The CDCO ad said it was for a 10" lathe, but maybe the ATLAS cross-slide runs small?

Thanks in advance for advice on these questions.

Should work just fine on a 10". I used one on my 9" SB no problem, & I think they will fit up to a 12" even. The tool holders are plenty adjustable. Should make you happy with the quick tool changes.
 
You normally have to fit the T-nut. Typically, a QCTP just comes with a block of steel that needs to be milled and fitted. You can buy prefitted T-nuts for the common lathes, I am sure one is available for yours. Also, the bolt needs to be a really good fit to the post. I highly doubt it is 1/2", it is probably 12mm. You can either make a sleeve or fit the stud that came with the QCTP to your T-nut. If the bolt is not a good tight fit, you will experience random problems with the post shifting, which can be a big problem when parting or threading.
I am not sure I follow you about adding a spacer under the post so it will swivel with out hitting the slide. The tool post must rest on the compound slide or the T-nut will slide back and forth. When you tighten the nut, It should bear down on the slide, not the nut.

The AXA is the correct size for you lathe and it should fit really well.
 
I have an AXA on my Atlas craftsman 12x36. On the 10" you have to mill, grind or file the hump on the compound. There are several threads on here about that.


I would use the bolt that came with the tool post. If you do not have a way to mill the nut that came with the tool post, there is a thread on here that shows how to machine the t nut on your lathe.

Thanks for the responses, people.

JO - The QCTP sits on the flat of my compound ok, but when you try to rotate it, the corners hit the hump on my compound. I was wondering if a 1/8" spacer could be added under the QCTP, because this gives the necessary clearance, but KD has described below removing the hump.

kd- Thanks for the thread advice - I will try to search those two out tomorrow.

if you have access to a 4" angle grinder, or even a dremel tool,
you could grind the hump until there is sufficient clearance,
or
you could nick the corners of the toolpost to keep it from interfering with the hump.

i'd consider bobing the tp corners, and leave the compound rest alone- if it were my project:)
you most likely won't ever be using the very lowest part of the toolpost v anyway .
 
I'd grind down the top of the compound rest. If you want to keep yours original they are widely available on ebay. You can buy a spare and modify that.
