Milling vise

A while ago I found this video by Luiz Ally:

In it, he shows a vise he designed and made with his Sherline milling machine. It's a very clever design and solves many of the problems faced when trying to clamp thin stock in a regular vise.

I decided to build one myself from a piece of brass I had lying around that was already roughly the right size. As anyone who's ever worked with brass knows, brass is 'slippery'. It has a low coefficient of friction. So it's not an ideal material to be used as a clamp. That's why I decided to add a pair of removable jaws to my version of the vise. This has the added advantage that since the jaws can be replaced, it's not a problem to machine them square to the table each time the vise is installed. The jaws can easily be replaced when they've become thin. Also specific types of jaws can be used to match the piece one wants to clamp.

I added a lot of extra holes spaced 25 mm apart because I wanted it to be compatible with the optical breadboards I sometimes use. Because my TAIG has three T-slots along the bed, another hole was added to the small side of the L-shaped part.

Below are some pictures of the result. A big thanks to Luiz for sharing his idea on YouTube. He has a lot of other interesting video's there so I highly recommend subscribing to his his channel.

I really like the combination of black and golden:

Begin van een moertje

Ik ben bezig met het maken van een moertje voor het onderstaande schroefje. Eerste stap daarin is het maken van een zeskant-schijfje met een gaatje erin. Dát deel is (afgezien van wat kleine schoonheidsfoutjes) al af, nu alleen nog even draad erin tappen...

Boutje M0.1 klaar..

Het complete boutje is inmiddels af. Ik ben nog niet helemaal tevreden over het kopje, maar het gaat zeker de goede kant op. Hieronder een filmpje getiteld "The smallest screw in the world":


Als bonus ook nog een elektronenmicroscoopfoto. Ik had verwacht dat er heel veel onvolkomenheden aan het licht zouden komen, maar het valt me eigenlijk best mee:
