From reading a lot of the lathe posts here I have a question , which quickchange tool post is the easiest to use and how reliable is it ?

I have to toolup a lathe for a friend and thought that a easy to use and quickly setup system of tool changing might keep him interested in machining.

There are many different types available on Ebay around the world , just want a few ideas , thanks .

Multifix is very good and very repeatable.

Hi Mike,
I have the Hare and Forbes QA150 and while it's a beautiful tool post it's expensive and so are the holders, so thats why I made my one.

Buy a BXA wedge tool post from the US (I think CDCO has wedge now) and they are around $200 posted with 5 holders. He will work with you to fill the flat rate box with extra holders for around $10 each.

Forrest did a review of the Chinese multifix tool posts. Do a search. The turned out pretty good. I can't remember if he posted a supplier of the tool posts and holder that was cheaper than most places. If not I have the link.

Being able to move the the tool in 15 degree increments is very nice, especially if you have a tool that wants a slight angle like a boring bar.

Either the Dickson style or if you want a little more tool room type, buy the Multifix or its copy. I remember there was a suuplier that you could get the Multifix style post and holders for about 200, http://www.createtool.com/.

Although my current lathe has an Aloris post, the machine it replaced had an Omni Post, which was a very solid, repeatable unit. Nothing fancy, just very good, relatively inexpensive, functionality.

There are many good toolposts, but the Aloris-style is the most commonly used. It's reliable and repeatable, and the toolholders are the most widely availble of the various types. Having a wide variety of sources and quality of toolholders should make it easier to stay interested. It can be frustrating to get locked into a one-source, one-price situation. The wedge style is more repeatable, but that's really not necessary for most hobby machinists. You generally need to be doing production work to tight tolerances to need that level of repeatability. BXA would be the correct size for his lathe. You can get a BXA piston style toolpost with a set of toolholders pretty cheap. Go to CDCO or search Ebay for BXA.

What I like about the Dickson is you almost throw a holder at it, turn a wrench, and off you go. What I don't like is the cost of the holders. I've got five holders, and I'd like forty-five.

On the occasion I want an unusual angle, I just turn the whole toolpost. The only annoying feature, which must be common to all designs, is when I decide to mount a tool in an empty holder and I forget what task it's for, and I mount it backwards.

While the Multifix looks more flexible, don't you have to think a little (more) when mounting a holder straight, or at right angles ? Or are those natural angles obvious ?

Thanks for the replies , I have passed on the replies to him and am also thinking of buying a few tool holders for myself as the Aloris that arrived with some tooling that I purchased recently has cleaned up quite well from the greasy lump in that was in the bottom of the box .

I have a Chicom Aloris-style QCTP on my 12" lathe and it's dreamy.

Straight is pretty obvious, as the usual is 9 degrees between positions and*it really can be seen that it is not straight.
