I am building a tool post and was wondering iuf any one had a good method for height adjustments, or should I tap a hole and use a bolt to do that?

Oh, come on- Get with the program. Use the same high-tech stuff as the rest of us. Washers, shims, nuts, paper, cigarette butts, this piece of swarf, strategic hope...

If you're doing an "Aloris type" with removzble toolholders, the bolt and locking nut approach seems to be the way to go, although the FIMS brand of toolpost does it slightly differently...can't remember offhand just what it is, but know it is supposed to be "better." Somehow.

If you do go the shim route, if you organize things it's not too bad. Have stacks of 10, 5, and 2 thou shims (or whatever seems reasonable) so you can easily and logically make up the height you want. Then have a handy place to store them when you're not using them!

Yea, one of mine takes .007 to shim up to center. I keep a couple of those automotive "handy packs" around for just such things.

Just thinking out loud, but what about a cam running through the main body instead of a threaded nut. Any advantages?

I was wondering about using a cam and a spring for the riser.

Being lazy, I shim only the toolpost - since all my tools are exactly the same height (for the "quad post").

Best way with the quick change is an adjusting screw and lock nut - this is the way most commercial posts are configured.

Thrud,
I was thinking of that also, this has been a learning experience for me.

I have hard brass circular shims (like a fenderwasher) for each of my goofy tool blocks - you must make sure all is clean with no chips in the way (same rule with inserts) before securing the post.

There is always more than one way to do a job - figure out what is best for you. I like my method because I don't have to have shim packs that just get in the way or disappear when you are not watching the little buggers (I swear they have legs). http://bbs.homeshopmachinist.net//biggrin.gif
