After drilling the holes and finetuning them to a perfect fit, I polished up the metal parts for the last time and assembled the saw. My splitnut driver has given up the ghost so it was time to make a new one. A real sturdy one this time. I bought a screwdriver and cut an opening with the anglegrinder. That's how I like my tools, quick and dirty.
Because the sawscrews are a tight fit, I literally hammer them into the handle. Trying to draw them in with the nut doesn't work, only damages the threads. The screws and nuts are now protruding a bit above the wood, so I file them flush and rub everything down on a sheet of sanding paper.
And then after cleaning everything carefully and oiling the handle a couple of times, here's a peek view of how it turns out. I'll make some better pictures outside when it's light again.
