Good morning;
Some great ides here. I'm cheeeeeeep so I make what I can, and buy the best when I have to buy.
No pictures, (I don't even know where they are now, but I made my self some inside and outside calipers for lathe turning of wood. The ones the size i needed were very expensive.
I started with 1/4" cold rolled rod. Lathe tapered the ends to a reasonable point. Bent the outside form over a 6" soil pipe. Bent the inside form with a railroad track chunk anvil. Heated and flattened the ends opposite the points. Drilled the flats and inserted a 1/4" -20 bolt with a star washer and wing nut.
After some tweaking to match the points, they worked great.
As my description said, I make it or make do. I wanted to buy a 55lb. anvil, but have by a railroad repair yard and talk to the maintenance foreman. Ended up with a 24" piece of railroad track. Rounde on top flat on the bottom, makes a great anvil. Just don't kick it or drop it on your toes. (two broken toes during spring garage cleaning)
