Chuck disassembly

[DC]

Does anyone know how to get this thing apart? It's a 1/2" chuck from a Dewalt cordless drill. I want to modify the teeth so it won't make such big marks on arrow shafts when I grab arrows with it

I managed to get the base off. It just pried off. But now I'm trying to get the jaws out. I can move them up and down by spinning the chuck but they won't come out. I don't see a snap ring or anything holding them in.

Maybe not made to come apart or alter.

Just a thought, you could open it up to 3/8" and run a grinding bur down its throat.

I tried that and it just ate the stone. It looks like the teeth in the jaws are hardened inserts. I used a Dremel stone and I don't think they amount to much but the stone is gone and the teeth don't have a mark on them.

I'm thinking it's pressed together from the ends and because the one end is cone shaped I can't grab it with anything so I can pound it apart. I might have to weld something on the cone so I can grab it. Maybe I'll look for another one first
Anyway, that kept me entertained for the day

It's amazing what king of info you can get on YouTube...do a search

I did. Lots of stuff on how to change a chuck but I only saw one on how to disassemble one and it was a different make. Sometimes it's hard to hit the right search terms though. There seems to be an art to that.

You dont need to modify the chuck to accomplish your goal. Take a one to two inch piece of metal or plastic tube with an inside diameter same as your shaft material. Slice the tube long ways, sand the cut to make a small gap between the formerly mated surfaces. Slide the arrow into the tube and chuck on the tube. The tube will close up some ( hence the sanding of the gap ) and hold even pressure all around on the arrow, no marks.

I've been doing that but since I use bamboo it's all different sizes and I needed 2 or 3 collets(?). I kept loosing them. They would also crush after a bit probably because of the thin brass tubing I was using. The best method I have found so far, although it's a bit time consuming is to chuck the shaft in the lathe and drill an 1/8" hole in each end. Then cut a couple of 2" pieces of 1/8" wire and CA them in. I cut the wires so that they weight 50 gr each so I can still keep track of the weight. They stay with the arrow until they are all sized and spined then just heat them up and they slide out. I re-use the wires. I just thought if I could modify the chuck it would fit multiple sizes and it's big enough that I wouldn't loose it(too often) I'll keep my eyes open for one that comes apart.
