Very cool Greg, I am enjoying watching this, thanks for taking the time to post for us.
Have the timber frame on my shed assembled, now for a roof.

I have to drive forty-eight, 4mm-0.7 threaded, slotted inserts into 1/4" holes in 1/2" MDF. I really like the inserts with Allen drives, but they weren't available in this small metric size.To set these reasonably straight you need a large screwdriver and a lot of downward force. I need them slightly below the surface. So the large screwdriver is a pain to push and chews up the edges of the hole. I have a box of miscellaneous, old screwdrivers. I decided to grind the end of one to fit the insert slot and a pilot point to hold it straight. It has a hex shaft, so after I ground it I decided to just cut the shaft off the handle and use it in my super slow, super torquey Makita drill.

I like to drive these inserts by threading them (using the inside female machine thread) on a cutoff bolt backed up by a couple of nuts. Where possible, I chuck the bolt in the drill press to supply that needed downward force. (Turn the chuck by hand; I'm not talking power-threading here.)
