Sorry I'm not sure how that happened.

It's a three way toolpost, so what is more natural than one thread per way?

Funny, as I said I don't know how that happened I only posted one.

The third one down seems to have the correct one. I'll check.

The gist of the post is I made a 3 way tool post from a design I found in a ME magazine No. 299 December 2020. It is a very good design as it doesn't have sharp bits pointing at the operator. Also I want to know if anyone else a has made one and what they think of it.

I would have liked to add a photo but I can't remember how.

That would be the Lamas (Lammas?) toolpost I presume. I have always liked the look of them but never got around to making one. Always wondered about not being able to fit a facing tool or boring bar in them "wrong way round". How do you deal with that?

Thank you Michael I'll do that.

As to the boring bar problem Lammas says to make more than one. The other is upside down with respect to the first.

Assuming that the thread is indeed open:

The feature of the Lammas toolpost that appeals to me is the ability to get the tool tip close to the back centre.

My standard toolpost is the GHT four-way on which I have rarely if ever stabbed myself.

I agree, I haven't stabbed myself on my four way yet either, but as you said I too like the clearance it provides. That's what attracted me to it.

That's an advantage I had not thought of. No more revolving centre body blocking the toolpost just as you get to the last cut! Very nice.

MichaelG.

Due to my accident prone history I'm the Usual Suspect! Not guilty this time though!

I marked two of three duplicate threads ready to delete them but was distracted, When i got back they were gone.

Deleting duplicate threads is a bit risky. There's always a chance another moderator will zap different altenatives, thus losing everything!

Who said one bad general is better than two good ones?

Thank you for looking into it. I managed to re-tell the gist of it and people are responding.
