Nice Tig welds. How did you hold and rotate the curved tapered section to do the welds?

after tacking, just rotate it with left hand while right hand fuse weld. second pass was done like this, melt puddle, dip 4 times, then balance it and do another 4 dips of the rod... rebalance... so on

this was the most difficult part of the project. the 1 inch balls are from a seller on amazon (named: smallparts). yeah, i know! of all places, amazon!

1.5" balls are from McMaster, they're actually 440 SS.

So far so good, are You going to post any pics of the tool being used?:D
How far below retail are You on the two You have shown?
I know someone that does passion parties for a living and I may consider making a line of products , I can't believe how expensive this stuff is.

actually, its over a pound in weight. also, with majority of the weight in the large sphere end... if there were an intruder in the house, i think even a woman can swing this thing and seriously hurt, if not kill the intruder if it were struck in the head. :eek:

When I ordered my spheres it said the 1.5" one was .51 pounds.

sounds about right. the 1 inch ball weights less then half that, plus the shaft.. i used 5/8" was going to use 1 inch tapered to.... well, we won't get into that. this thing weights the same as my hammer, and nearly as long.

I ended up getting 3/4" for the shaft. I will try to lathe a little piece to see how it goes. I don't think my atlas will fair well against the 316 though.

i had no problem at all milling that little flat spot on the 316. the 440 was another matter. there were some sparks and light straw colored chips. i was milling away .001 to .003 at a time. once i slow down the feed, it cut fine.

In school we made balls from round bar, 303 as I recall, but the kicker is we did it on a BP. The method was to rotate the head to the right approx 35* (I could be wrong on the angle, this was three years ago). The round bar was held in a chuck mounted on an indexing head. The indexing head was mounted such that the bar stock was aligned with and centered to the BP's spindle. The indexing head was also tilted to the right maybe 30*, but I'm not sure of the angles. Setting them was trial and error. A single point cutting tool was installed into a holder not unlike a fly cutter but with the tool parallel to the axis of the BP's spindle. The balls were made by turning the crank on the indexing head to rotate the bar stock while the tool in the spindle was cutting the stock. Periodically, it was necessary to raise the mill's knee until the entire ball was completed. Sounds weird, but it worked. We made 18 balls about 1 1/4" in dia. for the ends of the spokes on speed wrenches for our vises. I have two of the wrenches and will try to post pics tomorrow. Maybe some gray-beards around here know of this method for making balls. It was kind of cool but not practical for production.

Doc, the tool was HSS. Also, I just went to the shop and checked - the balls were not stainless, just 6061 (my bad), and are 1 5/16: dia. I'll post pics and details tomorrow in a new thread. Here, I just wanted to comment on the odd way we made the balls.

I'm afraid the shape may be a bit incorrect anatomically. Two additional slight curves are needed on both ends, IMHO.

I agree. Shape it like this one made out of brass.
