The seat base frame is now taking shape. The 19mm rod I mentioned last month has been machined, drilled, and tapped.
I have used a friend’s lathe because ours is not big enough to get the bar through the headstock. I thought the tipped tool I was using was blunt, being polite and not wanting to look a “gift horse in the mouth”, I didn’t mention it to my friend. Luckily, I didn’t. When I drilled and tapped the ends with a new 8.5mm drill bit for the 10mm thread, I discovered the bar I had been sold as mild steel was a lot tougher than that, probably something like EN 16 used to make shafts, etc.
For this job, it doesn’t really matter other than it could
