Fragment bowls and tool

Some time ago I posted on a new tool I had bought - a hydraulic press. I wanted to press some small bowls that would then be hammered on the anvil and stake.  I thought if I could purchase a hemi-spherical drill or wood turning cutter tool I could form the right shape into a piece of hardwood and use that to press the metal into. The only issue was that such a tool was not readily available; and the one that existed cost about $450. So the only solution was to make my own.

I started with a rusted small axe head I had been given - I thought that would give me strong hard tool steel.

After cutting the rough shape out, the filing, grinding, polishing and sharpening process took place - but as you can see from the series of photos below a strong sturdy tool was created.

And it did work - it cut the form I wanted and I was able to press some fragments of silver-plated EPNS. I tested it on soft wood first; and then hard wood on the end grain.

And after hammering and polishing these fragment bowls came up well.

Fiona liked them very much and has claimed them for her own - I will be pressing and hammering more now that I have the wooden form
