Brass Shop Hammer

**rossbotics** · Jan 24, 2017, 04:14 PM

I made this little hammer for adjusting work in the lathe chuck, seating parts in the mill vise Etc. It's just an all around light tapping hammer for whatever, I have for a long time just used a 1" diameter piece of brass about 3" long with no handle just to bump something lightly, So I decided to make something a little more appropriate.

The head weighs 6oz. and made from 1" diameter 360 round brass, the handle is made from 5/8" diameter 303 stainless steel round with a medium knurl, the knurled end of the handle is drilled 3/8" diameter X 3.5" deep, this balanced the hammer very good, the handle screws into the head with a drop of Loctite, different heads could be made of lead, plastic, copper, Etc.

Below you will find some photos and a cad drawing of the completed hammer

as always, thanks for looking and happy machining

Doug,
Very nice looking hammer and just the right size for light tapping. Thank you for sharing your plans. I would have never guessed 89 degrees for the on each side for the taper.

Thanks Paul and your welcome
The taper is 1° from the horizontal plane, the 89° is taken from a vertical plane

Thanks Doug, another beauty. I enjoyed seeing the radii at the ends of the handle taper section...First class!

It's always a pleasure to see your projects!

Very nice. The .257" tap drill is correct, also known as a letter F drill, but most people will just have a 1/4' bit handy which will work just as well.

I drill and tap a 5/16" hole using a 17/64" drill, works just fine, 1/4" drill is getting a little to tight, anything over 17/64" is getting to loose, pick your poison

(5/16 - 1/4) * 18 / 0.013 = 86.5 % depth of thread (quite tight)

(5/16 - 17/64) * 18 / 0.013 = 64.9 % depth of thread (much better, easier to tap, very little loss of strength)

For comparison, an 'F' drill gives...

(5/16 - 0.257) * 18 / 0.013 = 76.8 % depth of thread (deeper than necessary)

Congratulations rossbotics - your Brass Hammer is the Tool of the Week!

It's difficult to win this award with a common tool. This is our first winning hammer in years of giving this award, and I think we chose a good one.

This was another week with numerous nice entries; it just keeps getting better around here.
