Watch out for boiling lead trying to vent !

Broke my foot!
Sorry. That's a lie. I had quite a good evening in the garage.
Cleaned up to get brazed in the vice.
Couple of tacks. The other one is hiding.
The Tig welder is one of those Shermans that were flavour of the month on here a couple of years ago. Used the pedal. The welder was set at 155 amps. I was guessing really. I'm brazing the world's biggest heat sink, so it's always going to look cold on the shot put side. I think the rods can only take so much heat so I didn't crank it right up.
I can weld/braze in straight lines ok-ish but I have to repostion every few dabs when going round curves. I don't weld often enough to stay reasonable, unfortunately.
It was good of Mike, a few posts above, to warn me about venting gases. Squeeky bum time at the end when the braze closed up. Nothing happened though. I guess the lead didn't get hot enough.
Smartened up with a flap disc to get the thick off and then hit with the DA sander. It's had a hard life, ex MOD, but it is starting to clean up nice. There are plenty of gouges and knocks to even out. There's a casting line around the equator, and it's got the weight "6.25" stamped on it too on the bottom half.
I've no idea if the braze will do its job or even if it's going to be a good sheet metal stake. It is starting to look the part though.
There's probably no comparison but a number 5 ball head stake weighing 6.82 kg sells for £128.66 according to a quick search on google. The shot put was £13.98 delivered.

Overcompensating again.
It's not been welded up yet. I think it's now too much so I'll chop a bit off and rebore the end.
First time using a fixed steady on the lathe. I wasn't sure what to expect but it was no trouble at all. I'll use it more often in future now.
38mm en8 steel bar. Faced off, drilled to 7/8" and bored out to 25mm. I used a spare bit of the original 25mm steel bar as a go/no go gauge.
The steady didn't mark up the bar as much as I expected.
I've got one of these coming at a seemingly very reasonable price. I'm making another smaller stake. I don't fancy drilling it, so it will be getting brazed as well.
2" ball head stakes go for stupid money too. Have a google and be shocked.

The 2" steel ball arrived. Found a little bit of 22mm square bar. It stays gripped in the vice better than round bar, I need to get some more of this. Hole drilled in the end just to seat the ball. Corners ground back for better access. This allowed me to get a couple of tacks on in this position.
Brazed on its side once tacked. This was my neatest braze of the bunch.
All brazed up. |'ve got a pair of balls now. I'll let you know if it falls off.

Got the shot put fixed. It would have been a lot easier if I had some more square bar to put it on. It stands at shoulder height in the vice on the bench. I wouldn't want it any higher and this gives me the most room below.
My brazing has improved. I used pulse at 185 amps. 0.6Hz 36% on time I think. I think the background current was 60amps I tried using my garage made weld positioner but I had to use the pedal on the welder because the torch switch was stuck on and I couldn't cope with two foot pedals at once. I just ran a few pulses and then stopped to reposition. The braze is forgiving on restarts.
