three sided tool post

[tony bastickParticipant @tonybastick78554]

Hi does anybody know if and where i can get a triangular three position quick change tool post of a size to fit a myford I have a square one but its always in the way of the tailstock when doing small bits of work and it seems to me that a triangular one would be a much better design as it gives alot more clearance Thanks Tony

Hi There

Myford used to do one called a Tripan.

You might get one of Ebay or if you advertised(free) on here and/or Model Engineer and MEW free ads.

Might cost an arm and a leg.

However, an angle grinder would see part of a standard block removed.

Just chop a large corner off.

I made some about 15 years ago.I'm sure it was an article in M.E. , if anyone is good at searching?

[Derek GoddardParticipant @derekgoddard70466]

Tony, I am considering making one for my Chester Multipurpose, which will be based on the design of D Lammas. He wrote a brief article in MODEL ENGINEER on 2 Aug 1985.

Hope this and the Three-sided helps !

Why not get one of the extended tool holders for your existing toolpost, assuming its the Dickson type I find them very handy when using the tailstock.

Hi Tony , yes you can get a 3 sided tool holder , I bought a bare casting a few years ago at one of the shows, when I remember from whome I will post it up.

Try Blackgates Engineering. They do 3 sizes of castings for these tool posts.

Or their catalogue is showing them. Have to machine it of course.

Or get 2. One for each hand.

Another Ken.

[JasonBModerator @jasonb]

The Lammas one that blackgates do is not a quick change post which is what Tony wanted.

Pic of one on this page

Can't see the point of a casting, easier and cheaper to cut from a block of steel or iron

Hi There

Yes, a three way was done but not quick change.

Tony,

Forgive me if I am wrong, but I suspect you mean a 4-position click-stop rotating toolpost. If so, well, I had one, it was a right PITA – something always sticks out and slices your wrists, and you can realistically only get 3 tools in it anyway. Do yourself a favour and get a Dickson toolpost and interchangeable holders, they are just in a different league. If I've misunderstood, my apologies.

Hi, thanks for your info guys, looks like it may have to be the diy holder but a quick change version is what i was realy looking for .Im surprised that the far eastern suppliers have not come up with one yet. I have a couple of extended holders but they do tend to chatter on average cuts due to the overhang.
