The next job was to fit the hinges which hold the sewing machine into the base. I bought some slightly different ones from eBay which would fit in the side walls of the box. The trick was going to be getting them positioned spot on, so as Steve Maskery would say a jig is needed. Mine however was very crude using off cuts and miter bond to stick it quickly. I adjusted the old imperial thread in the bottom of the hinges so they would take an M8 Allen key bolt by drilling them out slightly and re-tapping them.
Here is a hinge, with a dowel center point in it, and the other dowel center point next to it.

And this is the crude jig.

I then put it at the side of the sewing machine with the hinges in place and pushed to get two small dents where I needed to drill for the hinges.

I then founded I needed a few more reference surfaces on the jig to enable me to clamp it to the base before drilling it.

Then it was onto my trust Aldi pillar drill to drill out the holes.

And these are the holes. Not much for quite a bit of faffing about, but they were in exactly the right place which was important.

I then needed to notch out the inside to allow the hinge to fold down. So I started by marking it out. (still not winning any prizes for photography, it's almost sharp!)

Then with a little bit of sawing and some use of a chisel I was able to cut out the slot.

And then a test fit of the hinges which were a very tight fit as an imperial fitting pushed into a 15mm hole.
