Hi all,
Decided it was time I produced a soft blow hammer, on account of me using a regular claw hammer and brass drift for things like tapping end mills into the head-stock and removing chucks etc.
Apologies for no action shots, just the finished product. Fairly basic in all respects, although I did toy with the idea of interchangeable faces for nylon and lead etc I decided for now solid brass will do just fine.
And I got to use my radius turning tool (http://metalworkforums.com/f189/t198915-hercus-radius-tool-project), to cut the shoulders on the handle, which it did a fine job of. I finished the handle with 400 grit paper and a diamond knurl. And in the process learned that feed speeds for knurls on one diameter of work do not produce the same pattern on another diameter of work. I did a test pattern on a scrap piece of about 40mm stock, and then discovered it produced a totally unacceptable knurl pattern on the much smaller handle. I had to skim it off and redo it, after first working out which feed to use.
The head was drilled, tapped and recessed for the handle shoulder in the 4 jaw chuck. I got a very tight fit actually, just taking very light cuts and sneaking up on the final diameter of the recess.
Cheers,
ratters
