Dividing head for the shaper

[mhh]

1. I apologize for the bad English!
2. I'm new here, and I usually make things that are a lot bigger than models, however this one of the more serious forums, and there is a lot of very skilled people posting and the reply is pretty large so that's why I chose it.

I ran into some trouble awhile ago,I had this pulley that should fit over a bigger shaft than the original, so I bored and reamed the hole, no problem there, went over to the shaper to broach it so i put it in the vice and SLAM! the pulley bent in the vice!
So to avoid that happening again I'm going to make a simple dividing head and fit a 11" 3 jaw chuck that way I should be able to clamp future pulleys that needs broaching, without the possible danger of bending them!

Here is the the first drawing.

Hi and wEc1 mhh

don't worry about your English ,i still can't speak English :big:

sounds like you have a fairly big shaper ,they are good for bending things when it goes wrong ;D

your fixture looks like will be able to index the chuck,,,,,,,will you be adding some sopport to the rear of the L section ?

Regards Rob

It's only a sketch so yeah there will be support on the back. It will be able to index mostly because I sometimes have the need to make crankshafts...... and... BEACAUSE I CAN ;D

But keep on looking! there will come pictures! I'm currently looking for the lumbs to make this beast!

Mads:
Do not worry about the English skills do your best. If it were not for the spell check mine would be a little ugly .

Update pics!

First picture: The 300mm(about 12'') devil in a set of freshly welded jaw the weight is about 62kg(136 pounds) heavy as hell to get in!

Second, third and fourth picture: The first few cuts at about 160rpm 0.15 feed.

Another update

First and second: The next cuts from 300mm to 140mm (roughing) started from 160rpm 0.03 feed and 5mm diameter(2.5 depth) and ended at about 250rpm same feed and depth.

Third: Finished surface (130mm) about 315rpm 0.015feed and 0.5 in depth really nice result.

Fourth: Treaded M130x1 ;D
