I got the psi collet chuck for Christmas. Where or can I get some in between collet sizes?
Thanks,

Ive purchased from this person on ebay and they are 9.50 per collet and free shipping if you buy one or a hundred.

So was I! Actually, several sites having "collet charts" only showed the er-32 collets going to .750"I agree! For some reason I was under the belief that the ER32 only went to 3/4". I see a few I will have/need to get to fill out the imperial set.
I only use the basic set, if I need an odd size, I cut a piece of 3/4" dowel and drill it to the size I need. Then I cut slits in the dowel like they are in the collets. My only problem are the the sizes close to 3/4", and that has only happened once, I made that one out if Delrin. Delrin isn't very good for making collets, but will work if you take your time. Saved enough for another tool.
How do you know which is a ER32 or an ER16??? I just bought a Beall from on here and the body has no numbers on it and I would like to order more..

Unless money is extremely tight, you are probably better off to buy a set from 800watt. Price pre collet is about $4 or a few pennies more. You can't hardly make your own for that price if you value your time at all.
BTW, it is best to buy a metric set rather than an Imperial set. If you look at the sizes available in the Imperial set and the 1 mm grip range, there are a couple of gaps in the grip range in the Imperial set. It's probably not a big deal and only a rare occurance when there would be a problem; but the price difference between the two sets is not enough to really worry about.
Collet types mainly vary by diameter and length which dictate the type of clamping housings to use. You can dig up sizing charts all over the web that give the physical dimensions of the different types of collets but for your purposes, the easy answer would be that the Beall collet holder uses er-32 collets as does the PSI collet chuck.
