How to make a reducer collet for your Dremel 732 running a 236 handpiece

Here's a solution that John from Dargaville came up with to reduce the collet size on his Dremel 732 to 3.2mm (1/8") so he could use the range of Dremel accessories that have 3.2mm shanks.

His Dremel 732 is fitted with a heavy-duty 236 handpiece and reducing collets do exist apparently but are very difficult to find.

The "Dremel Trio Collet Adapter For 3.2mm (1/8") Shank Accessories" we sell has an OD of 5.9mm which will fit inside the 236 handpiece (where the 6mm shank accessories would normally go) so we sent one to try out.

It didn't work out of the box but John was able to machine a small brass taper to fit over the end of the collet. There you go, it works!

Now he can use the wide range of Dremel (and other brand) accessories that have a 3.2mm shank.
