$100 seems like a lot for a (mostly) plastic part, but given that it has bearings, and they've done the troubleshooting, it's probably not a bad deal.

There is a metal threading dial for a 16" lathe up on ebay for about the same price, maybe that would?actually work?

I should also add that I parted 4140 on my SB9A without any drama using this tool.

Mark,

l was the one the wrote about making a tool and the version I was going to make is similar to your Armstrong adaptation, which you said had problems.

Therefore, I did make a tool using your latest plans. (see pics below) Obviously, I can't follow directions. My goal was to make a parting tool without using a parting tool. One thing I did that might be useful is that I cut the blade groove .125" deep for the carbide blade shown in the pics. Thinner blades can be used with a shim under the retainer. I have 3 different thicknesses of blades so I wanted a way to use all of them. I am thinking about adding some marks to indicate the blade angle so that it does not need a gage to change angles.

That Bambu a1 Mini is pretty remarkable, especially at $200. Thanks for the post. Your threading indicator is first class.

My history with 3D printing goes back to the early '90s, shortly after 3D Systems introduced the technology at $250k per machine. Jumped back in with a $2k machine three years ago that also had a laser head for engraving/cutting. Material choices with it were limited, and surface finish was nothing like the Bambu! (Commercial production machines still go for multiples of $100k, of course.)

Viva innovation!!

I'd trust the listing for that, although that's certainly a wide range of lathe sizes for one item.? If you can share the link we can take a look.? You can probably get it cheaper if you find the model and have a service like shapeways print it and mail it to you, but it may not be a big difference in price.

You can also buy a perfectly nice 3d printer for around $150-200 these days, so consider that the part might be a significant fraction of the cost of a plug-and-play printer (e.g. a Bambu a1 mini)

I use a 3d printed threading dial on my 10k and it works great! I had a friend print the body and gear at 100% infill, then I turned a brass dial and press-fit that on a shaft.? I sanded the plastic parts, primed, and painted so it matches my lathe.? You can see the finished version here:

In case you couldn't tell from the pictures the cut off tool mounts to a standard holder. All the tools will be sold with the blades. I just haven't decided on a price. I struggle with pricing.

BXA holders are sold in two sizes. Measure your holder front to back and let me know which. I think it will be 325" or 3.50".

Yeah I was going to sell a tool that bolted to the top of a holder and decided to by holders and sell them with the tools. Too many variations of the BXA? ?to keep up with but the dovetails are all the same.?

Yes, there have been 3 videos on this tool but the last and best version is in this video. There is also a link to the plans in the description.

Thanks Mike, the parting tool works very well. I've actually made five designs variation over the years. I think I finally perfected the design. As long as the feed rate is right (about .001" to .002" per revolution) and you give the blade a constant supply of oil it seems pretty much fool proof. Even the speed is very forgiving, as long as the SFPM is correct or slightly slower than spec for HSS. I just made 10 of them. I plan on selling them complete with the AXA Holder, Blade and a Needle Oiler. I sent one to Quinn Durkin (Blondiehacks) and she love it. She said it has become her go to parting tool. Can't beat that for a positive review. Not sure on a price yet. The AXA tool holder and blade add up to $35+ and the steel and bolts all add up quickly. It took me about 20 hours to make 10 although if I make more I'm sure that can be reduced. I want to keep the cost reasonable but also cover my time and expenses.

Mark,

Can this be resized to 0XA size?

Thanks for all you do and try to show us how to do for ourselves..
