Broken Router Collet
I have a Bosch 1611 router that I bought used. When I bought it I asked the previous owner about the 1/2 collet and he said it was there. I didn't check it when I got it and all it had is the 1/4 collet. The router appears to work good and I only paid $15.00 for it so I figured no big deal and I ordered a replacement collet for it, Bosch part number 2610906289.
I am using it with a Kreg router table to make some raised panel doors with a set from Grizzly for kitchen cabinets. I am using a variable speed control from Harbor Freight, turned as low as it will go. I ran the first set, styles, rails and panel cutter without problems other than the whole table vibrates more than I would like.
Today after doing a set of styles and rails, without any problems at all, I went to cut the panels. When I was running my first test piece, the cutter came out of the collet. I did not have the little plastic guard in place. I guess I was lucky as it didn't hit me. I thought I had tightened it enough but then I thought maybe I didn't. So next time I'm sure I wrench down on it and slide the guard in place. ( At least I learned a little) I start it up an a very short time later the bit comes out and this time it wedges between the table and the plastic guard.
OK, better than watching it spin through the air. So now I take the collet apart and see that it is broken in three separate segments. This is a one piece collet and nut
and the part that broke is the segments that are attached to the nut.
I know this is not the best setup for a table. Now I'm not sure I feel comfortable using a replacement collet in the same setup. I always go the cheapest route first; buying a $15 used fixed speed router, harbor freight speed control, you get the picture.
But the only thing that I can think of that would cause the collet to break is if I didn't have the bit far enough in when I tightened it. I'm not sure if it would break if I tightened it down without anything in it.
Enlighten me on where my problem is. Should I scrap it for a better setup?
