Alex demonstrates a homemade jig enabling accurate cutting of female pin headers using a Dremel.

I have an occasional need for 13way female headers. Actually they are a component in both the RasPiO 7seg kit and the RasPiO Breakout.https://shop.rasp.io/products/raspio...

But 13way headers are not as easy to get hold of as other sizes, e.g. 15way, unless you want to order eleventybillion of them imported directly from China. If you only want a couple of hundred or less, it's better to buy 15way and cut them down to size. It's certainly quicker if that's what you already have in stock.

It's rather an unpleasant job, but to do it well with a fair number of units you need a 'machine'. Ideally a small modelling table saw, tile saw or something like that even an industrial guillotine would do it nicely. But how do you do it in a "hacker's garage" using just what you already have?

Well my solution is to use a Dremel clamped into a jig to make a kind of small table saw. It's certainly not as safe as I would like it to be. One day, perhaps I'll make a modified version that places the 'table' above the blade. But this is what I have for now. It's an interesting hack and I thought I'd share it with you. Enjoy the video...
