Which collet set to purchase

Will be going to the show this w/e, and nedd advise on which collet set to buy.Have a myford ML7 and will possibly order a waco mill.

Thanks

There was a similar thread recently that advised not getting a set as most of them don't get used. Just get the one you need for the particular job.

I suspect that Michael is asking which style of collet to get, not whether a full set is required.

Personally I would say to get an ER32 set of collets with the holder to fit your, about to be purchased, mill. In addition I would suggest getting a myford screw on collet holder, be it direct fit or flange and back plate , do not bother with a Morse one for the lathe as this prevents using long lengths to fit through the head stock.

Again, given the choice, I would pick a collet holder with a separate back plate for the lathe because a. it allows you to, at some time in the future, fit it to another back plate for a larger machine and b, it allows you more scope to get the thing running truly by means of "bump true" and judicious use of tin foil packing. If you were to buy a direct mount holder and it were to be a off, the only way to correct it would be to re-cut the taper, which would then not align to the thread which in turn holds the closing taper. Re-cutting the taper accurately is perfectly possible but it might be outside the scope of some of the less well equipped machinists.

It would be worth reading Harold Hall's words of wisdom, posted a few weeks ago, about collets not closing, but don't let that put you off.

PS if DC1 is reading this, why does the spell checker not recognise "collet", seems a bit odd for an engineering site.

Hi,

May I point you to this thread

Not having looked myself, but do remember seeing a "dictionary" section (or function) in some "Spell Checkers", does this version have one?? ------ this function allows the user to add a new word if it is not in the basic "'checker", when it is present

Thanks for the advise, will be most likely purchasing the myford screw on collet holder,

Thanks again

Hi Michael

Yes I can recommend that one but, in case you have problems fitting it, see this thread.

I admit I was stumped for a while!

Michael, possibly to late but have a look at this thread

Not so sure here! I have four ER25 collets plus another four home-made ones and continually regret not having a full set. The home made ones are OK for the size they are made but don't seem to collapse as well or as far as bought ones. They are made of medium carbon steel.

I think if you have all the sizes you are much more likely to use them instead of a chuck.
