I love my Eagle 66 oil cans but they seem to tip over a lot since the bases are so narrow. I decided to improve them by machining some beefier bases out of brass.

I Finally got all of the holes bored and the weld bevels cut a hole drilled for a set screw or locking bolt. After a death and a funeral . And a ton of honey
Dues .

I got all of the brackets on the shaft and ready to start tacking into place . Then take it back apart and weld it out .

sorry it has been so long since an up date. Months. But I have found so little time for the shop with Sandy and work. But the picks are of how far I have got. Have got a couple thing done. But the mill has not even had the vice mounted.

Your shop looks good

Few things got done over the last couple months. First is getting my 15 year old to weld up some bars for the window.

Second is a mounting tab I had to make for my 84 super glide. (Had some old 5 gallon tanks so I fix them up and painted them) I'll try to be more active here again.

POTD was making another punch/die for a project in reproducing old Erector set part number ‘NU’ parachute jumpers. The parachutes have paper washers on either side of the chute material with a brass eyelet holding them together. I made a 5/8” punch with a less aggressive center “prick” a few days ago, this punch/die were for finishing off one style of the disks made from the 5/8” punch. In this case I needed a 3/16” diameter punch. Had 11/64” and 7/32”, but alas, no 3/16” . . .

My Roper Whitney #218 punch press uses 1 ¼”, 2 1/8” or 2 ¾” dies, and punches either ½” or 1” diameter. Made the die first. Started with a slightly over 1.25” diameter O-1 round, turned down to 1.25”. Then bored out the round to depth/diameter which is at the bottom of the die. Cut off the round on a band saw and back to the lathe. Faced, center drilled and drilled/reamed to a 3/16” hole. I was shooting for about 0.005” clearance between the punch and die, so then ran a #11 drill bit (0.191” diameter) through the reamed hole. It was only scraping 0.002” on the radius so figured it’d be pretty close to the correct diameter.

Did the punch from a piece of ½” drill rod. Simple turning job to 0.1875” diameter (3/16”). The shank got a relief area for an anti-rotation screw in the press punch receiver. Parted and cleaned up the nib with a table top belt sander.

Hardened the punch & die with an oxyacetylene torch, then tempered to ~460 F on a Thermolyne hot plate.

If you are interested in what I’m doing with the 3/16” punch, hit the link below for the ‘NU’ parachute jumper thread.

I remember having a lot of trouble with those big old tanks. Had the 5 gals. on a '79 LowRider that I toured the US on for several years starting in '80. Needed the extra millage. I had the threaded holes break out too. That's where I learned to weld gas tanks without blowing myself up!
