I am a total newbie learning his lathe.
I found out from this group previously that the quick change to hold her that I would need for my atlas 10 inch Lathe would be an AXA 250–111. If I am remembering correctly I was given a link and found it on eBay.
?
Question 1:? I went to eBay and found various options and makers.? Should I be concerned about the unit I buy being Bostar or Labworks, etc.?
?
Question 2:? Knurling tool - two types - which would you recommend??
I see two options within the Bostar brand:
A.? a Bostar unit selling an 11 piece set where the knurling tool is a a 250-110 that has the knurling integrated on one end and says the unit, "Can also turn with bits up to 1/2."??
?
B.? Bostar has a 10 piece set with its knurling attachment being a separate unit that fits into a 250-101:
?
Merry Christmas!

??? Just plan if ya buy a import & this goes for chucks also
& just about anything with more that one part that yer gonna
want to dissemble the unit & clean out all the manufacturing
smeg & ya may want to re-clock the handle . I took mine apart
when I got it to re-clock the handle there was a lot of shavings
left over inside . Take pics if ya do this project , they may come
in handy on reassembly . I'm not a big fa of the knurler that
comes with the QCTP . I'd rather have a plain tool holder &
get/build a scissor knurler .
YMMV

I'll second Mikes recommendation for the scissor type knurling tool. They put far less stress on both the lathe and the part being knurled.

I have a Bostar wedge type. ?It has been very solid and repeatable. ?I cleaned and greased it when I bought it but it was pretty clean. ?
Also recommend a scissor knurler. ?I might have used the Bostar knurler on brass. ?The Atlas doesn’t deal well with force needed to knurl harder materials. ?
|
I've bought many extra tool holders from Shars which are well made and cheaper than most other suppliers.? I assume their tool post would also be fine.? You'll get a "bump" knurler with the set but, as others have said, you'll definitely want to get a scissors knurler instead.? I altered the "bump" knurler that came with my original set into a tool holder so it wouldn't go to waste.?
|
As always, I really appreciate this site and the members.? Thanks for the info.? I did look at Shars, but in this case they are more expensive.? I think I will look into, when I get more hours under my belt, a scissors knurler.? I ordered the 10 piece system.? Maybe changing the knurling tool to a scissors type will be a future project for fun.? I also will definitely take it apart (and take pics!) and clean it first.

Merry Christmas!

The scissor type squeeze the part.? The other type PUSH on the part which puts strain on the bearings of the spindle.? Get the Scissor type or make one.? They are easy to make but have lots of parts for a newbie.? (NOt really)
|
I've knurled a handful of things using the old, atlas lantern style tools and the QC one that came with my Phase II AXA tool post. Since then I've stopped trying until I get a scissors type made or bought. I find the off center pressure on the QCTP makes it creep out of square.

??? Forgot to mention that the Dog Point screws in each tool
holder are usually garbage , real soft screws . When I first got
my tool holder set I went to my hardware co & bought a bag of
100 new quality screws , thats enough for 25 tool holders .

You can make your own scissor knurler, too. Except the knurls. Unless you need something special, in which case you can make them, too. Depends how deep down that rabbit hole you want to go.? 
https://littlemachineshop.com/projects/knurler.php? is a knurler you can make yourself, though they'll be happy to sell you one, if you prefer to buy. Yes, it's for mini-lathes, but most of the accessories I bought or made for my HF 7x10 fit the Atlas TH42 as well. MT3 Spindles, and MT2 Tailstocks, for example...? Some adapter plates for chucks and such.?

I did just that in a class or two at Monroe Community College.? As the old guy auditing the course they pointed me at the donated drops supply and said make stuff for your shop.? The wheels came from Amazon for under $10 and seem to work fine on aluminum.? I haven't needed to do anything in steel yet but I don't think it will be a problem.? Pivots and wheel axles are 1/4" dowel pins, bolts are 1/4-20.?? I really should make a knob, the wooden one is from my CNC router clamps.? Arms should have been about 1/8# shorter, it is a bit tight to get onto the stock without opening it up all the way.
