I'm considering a collet chuck and collets. I have checked out the ones on e-bay and think that either ER 25 or Er 32 are about the best overall. What is the advantage /disadvantage of the larger set size of the ER32? Will a ER 25 do most jobs? 800watt has some good prices for sets, but limited for the MT2 that I need. Any thoughts??? Thanks Bob

ER-25 collets have a maximum size of 16mm - far smaller than most of what I need it for. Ideally, I'd have a 5C chuck and full compliment of collets - but those things are *expensive*.
 
Get a Beall collet chuck and a set of ER32's from 800watt. You will not be disappointed. Chucks for ER32's are available from other places. I consider one that screws onto the lathe's nose threads to be a better choice than an MT2 chuck. ER32's go up to 3/4 of the inch...ER25's don't come that big...maybe 1/2 of the inch is the largest.

If you just want a better way to hold a mandrel check out MT2 collets:

Do a good turn daily!

I di what Don Ward did and love it. I bought the beall set but when it was discussed here about that guy selling the kits on ebay, I went and bought one of those and man that thing has been used alot. Great for doing cartridge pens and turning round blanks. Another good investment.

I wish I knew that. I just gave away about two dozen 5C collets..
 
If you buy a set from 800watt, get the 21 piece(?) metric set. If you buy the Imperial set in 1/16ths, there are some small gaps in the grip range. Probably not a big deal for most people; but the price difference is so small that there is no point in not being safe!!
