Welcome to the forum, @smithdvsd .
This Router is by default 1/2" you only need the Collet to use the 1/4" bits. I am looking for a collet myself. The alternative is to make one. Difficult but not impossible find someone with a lathe.Hi Roger I'm sorry but you are SOL, it's time to buy a new one for about 100 bucks in the combo kit and you get it all in a new router kithttp://www.sears.com/shc/s/p_10153_12605_00917543000P?prdNo=3&blockNo=3&blockType=G3 And use the old one for the light jobs
if and when you find a collet for it.. =========
