anyone ever tempted to make an axa qctp holder on the mini mill? Think it's capable? Maybe too heavy of a job for it? You can never have enough tool holders.

I'm sure your little mill can do it but with the cost of materials, cutting tools and time, I think it works out better to just buy the holders. With that said, even a little Sherline mill will cut tool holders so I'm sure you can do it if you're willing.

Hmm.... they are only $27 somewhat locally, and I'm sure the tooling would be over 100. Dovetail cutter, a roughing end mill (which my local store doesn't carry, actually........ :cautious:), the chunk of steel.

Fiiiine.... ill just buy a few more eventually. But I suppose, if I were to want to make 5 or 10 more, making them would be the name of the game.

Lol. Drive to buffalo. Just a 4 hour drive for some qctp holders. "Hey honey, I'll see you in three days. Gonna go buy some tool holders.". "Like f*** you are..."

I'll be honest, I was watching this old Tony make some holders on his shaper and thought "I can do that!".

I'm planning on making some on my LMS 5500 bench mill. Key word there is "planning". I have bought some extra holders before, but I didn't have a mill then. And the way I figure it, I'll wind up with a new dovetail cutter even if the toolholders wind up as paperweights, and who doesn't need another specialty tool? Especially cool ones like dovetail cutters? The world turns on specialty tools. It's science.

Might be awhile before I can get to it, though. Life keeps getting in the way. And that's a good thing.

Huckshawn, you can, with patience, make almost anything on a mini-mill. I have a friend with one of those mini-mills that have a hollow column and a 1/2 hp motor with 6 speeds. He does fantastic work with it, but it takes a lot of patience and some skill (that comes with time and training). I say - go for it! You will end up with a great project, and likely some tool holders. After all, we bought these machines to use them!

I'm doing it right now. The bits of steel were $7 each. I made a dovetail cutter from a carbide insert that only had one good corner left and a piece of cold rolled that came from Home Depot. A cobalt 2 flute end mill from KMS Tools and I'm making chips. My LMS 3990 is doing amazingly. Big, nasty, sharp chips flying everywhere! I'm brand new to machining, so the practice is great. $27 plus shipping or a five hour road trip, or $7 and lots of practice. I'd say go for it if you are not in a rush. If I do this again I won't get Metal Supermarkets to chop the steel up. It would be much better to cut a long dovetail then chop it up (like TOT does). Oh well.

Aluminum?! I never considered aluminum. I'd be afraid on a heavy cut the bottom end of the slot just shearing right off.

The strength of 6061-t6 and hot rolled steel are very close. Al deflects more but it is not appreciably weaker.
Buy a chunk of 7075 t6 and you are as strong or stronger than Cold rolled.

What are tool posts usually made out of? Hardened steel, no?
If it's comparable, why isn't it offered commercially?
I'm not slamming, I'm genuinely curious.

Because Aluminum is more expensive and it would offer no real advantage for most users. For the hobbyist, its is a little easier to machine so that might be a good reason to use it.

The tool posts I have are made of aluminum and then coated. I made these and have tested them. There is no issue with them at all. In truth, how deep of a cut are you going to take with a small lathe? There is no reason to think they will not hold up. I have tried them cutting brass, aluminum and stainless steel. No problem. Also, for what it's worth, the pieces i had used cost me 3 bucks from ebay. They were bought for a different project which never came to fruition.

They are usually made from steel, that is then either through or case hardened after the fact. The only thing the hardening does is make them more wear and impact resistant, it doesn't change it strength there any way.

You can in-fact buy small aluminum ones for 7x sized machines.

That's what I meant to say. I had purchased a QCTP for the mini lathe and it came with tool holders made of aluminum.

I have already picked up some steel from the scrapyard and bought a dovetail cutter....now I just need the time.
This working every day thing is for CHUMPS!

@Hukshawn,
I have found some with "not terrible" shipping in Canada, but better prices by quantity than singles:

I cannot personally recommend them, since I have not tried them......but those links have been sitting in my ebay list for a while......
(they do show a drawing with dimensions in the listings, so be sure they fit your post!)

Please let us know which way you go and how it works out for you.

Unless you're a journeyman machinist, make your own tool holders. You will learn and it's rewarding.
Unless you have other more important projects, I guess it makes sense to buy them.
For me personally, making tools like this are my projects. If I bought everything I'd have nothing to do.

That's accusize. They're an hour from me. My whole qctp is from them, I have 7 or 8 tool holders. But come on, you always need more. The only complaint I have is the set screws. Cheap crap. I will change them one day, for now, I haven't stripped out the Allen hole yet.

My shock here was with the idea of an aluminum tool holder. Just seems, wrong...lol

In a way, yes, if you can find some 7075 grade aluminum, probably in plate, it would make excellent tool holders. Just use the tool holders for those cutting tools not used often and it should last a lifetime. If you do wear one out, toss it and make some more.

Pull the set screws, toss in the trash, and replace with socket head cap screws. May have to turn the heads down for those that fit too close to each other. Also face them off a little and you brave enough, cut a half dog point on them. Now you have a heavy duty set screw!

I like it!
I'd say something along the lines of 'ill add it to the project list', but man, it a mile long.
