Myford rear toolpost

Nice Job Alan!

That's not a Myford rear tool post that's a rear toolpost mounted on a Myford and as built it's clearly not adjustable for centre hight.

Martin

Martin is so correct.

Apart from a slight advantage in having the "parting tool available all the time", I have never found the need to fit a rear mounted tool, much of the hype for such tools is over stated.

A properly set up blade + insert on the normal front QCTP works every time (for me) on all my lathes, large and small.

Now argue about that.

If that is the case, I think you should return it.

So far, there has been several solutions for you - Neil Wyatt has given you two and Merry Miller has a practical solution, with many others taking part. So it boils down to two options with the skills/equipment you have I think - either modify the tool or change the holder. If you keep it, the tool can easily be modified. If you do not have the skills/equipment to modify the toolpost, then you have to change it.

Kwill and Martin make a good point and I can see what they mean - there is little time saved and it gets in the way sometimes, but having got it, I use this (excuse me for not cleaning it)....

That's very neat, Alan

That's very nice Clive, even if too dirty to be posted in good conscience! No really, I like it!

This RTP may be like Alans, made by a toolmaker many years ago, could have been from plans I'm not sure. I find it very useful for grooving and parting without problems.

Not that I am aware of, I haven't deleted anything and if I have edited a post it will say so at the bottom.

Sorry to take issue with Mark P, but a rear toolpost is a boon. It seems to solve parting off problems for many people. This will probabl;y reignite all the theories as to why/how!

I was sufficiently impressed with the results from the one that I made for my ML7, that I made a four way one for its larger oriental successor, to carry a front chamfer and back chamfer tool, as well as the parting tool. It VERY rarely leaves the Cross Slide, maybe because of the chamfering tools, but wouldn't be without it.

Again, my advice is to mod the post, as a "once and for all time" job, in case you ever find the need to mount any other tool on it.

Grotto,

My summary:

• The toolpost is about 2mm too high
• The base has a tongue, which you would prefer to keep
• You don't have either a milling machine or a shaper

My suggestion:

• Saw the post into two, at some convenient horizontal.
• Face each part in the lathe [having first checked that the lathe faces 'flat' or 'very slightly concave' as per Dr Schlesinger's recommendation]
• Re-assemble, and check the new height [repeat, or add shim, as required]
• When it's "just right" you can [optionally] add dowels, adhesive, or whatever, to keep the two parts in register.
• Live happily ever-after
