Project: handle-less hammer

<=== Prev Next ===>


Friday, Jun 9 2017

I have both a brass hammer and a soft (plastic headed) hammer. When I want to tap something into place in a lathe chuck or make sure a part is seated in the mill vice I find the handle of the hammers gets in the way more often than not. A piece of scrap steel that used to be the counter weight for a light on an arm looks to be just about the size I needed for the body of a handle-less hammer. I have to turn it down a bit to match the brass stock on hand that I’ll use for one of the hammer heads. I also have to order some Delrin for the other head.

The body has a rough finish at this point. I’ll make it prettier after I thread the other end for its head. Not that it will be very pretty. It is a hammer, after all. The threads are approx 17 mm with a 1.5 pitch. They didn’t have to match any specific spec, just each other. I was quite happy with the results, especially since this is the first time I can remember turning inside threads.

The improved lathe banjo I made makes setting up change gears for thread cutting much easier.

A bar of the generic acetal (Delrin) I ordered arrived this morning. I cut off a 30 mm chunk to turn down and thread. I also threaded the other end of teh body. When the parts were screwed together I turned down the acetal to match the diameter of the body, then skimmed a few thousandths off both head and body to clean up the tool. Good enough. It feels good in my hand.

This picture shows the light steel angle iron I riveted to the lathe back guard to hold my tool holders and tools. No more turning around and digging through a toolbox drawer to find the tool I need. I could use a few more tool holders.
