Sadist.

All I want is to hear the story of how he made it back to Mexicali.

I worked on the battery box today, got the body done, it still needs a lid and mounting tabs.

I made it out of 16ga steel. Instead of trying to use the bender, I scored it with the cutoff wheel then bent it at the scores by hand. Much better results. The bent corners do need to be welded to get their strength back but it's a really easy weld to make.

I was able to weld the edges up really quickly which got the torch pretty warm, so I stripped it to see what was getting hot. Nothing seemed to be overheating, just a healthy hot.

The box goes above the swingarm, under the air filter. It's a tight fit, but should work. The picture is with the swingarm at the top of its travel. There's a little piece of wood taped on the bottom which will allow the ignition module to fit.

Here's the box with its contents. Battery, starter relay, ignition.

The voltage regulator mounts on the bottom so it can cool.

Nice tip. I don't have a brake, and occasionaly need to bend metal like that. I'll have to remember that one. How big is your tig welder. Mines got a pretty low duty cycle and warms up a bit when continual welding. I just let it sit for a minute now and then. Guess that's why fab shops step up to water cooled torches.

Keep up the good work and sharing your progress.

With all the projects being worked on, some of the shop tools are showing the strain. One of the key assets in the LC Garage is our PPD or "Precision Polishing Device". This unit has taken a beating over the years and in the last few days has started to come apart at the seams. The fancy label says "sometimes bearing needs lube"

Picked up a new polishing wheel today at Lucilles (small tool store near where I work);

Ready for another year of precision polishing!

Awesome! I just put a polishing wheel, new cable, toggle switch and rubber feet on mine! Altho, I need a new stone, wire and maybe a couple more polishing wheels!

The welder's a 130A stick inverter. For TIG I'm usually running the current between 50 and 70A, so that part runs cool.

This is the first time I've warmed up the torch anyway. Usually I'm fussing around for 15 minutes for each 30 seconds of welding.

Why do I feel a sudden urge to install security screws on the float bowls?

This would be a very wise move, since Rick has unfettered access to his own shop.....DAMHIK

They are just busting my chops for "polishing" the floats on Paul's SL350 (last winter), and this one got caught in the wheel, flew across the room and was ruined. A vigorous discussion then ensued on the proper use of the bench grinder or "precision polishing device".

MortimerSickle · 02-07-2013, 08:44 AM

Oh, sorry about that.

Good to hear you're supporting the local shop. It was pretty quiet when I was there last now that Harbor Frieght opened down the street.

Thanks, I almost forgot and went to the box store, but then remembered our friends in the local small shop. Got to do our best to keep the mom and pop stores going!

The battery box is mostly installed, but turned out a bit crooked. It was a pretty frustrating day and I just wanted to get it mounted. The welding mask started flaking out, which made the welding pretty hard- it'd cut out randomly while welding. Now that the box is mounted it should be pretty easy to straighten it out, though.

It's a tight fit with the swingarm.

I mounted the seat pan. It's got a hook in the front and a tang in the back that is pinned in a clevis. I missed some pictures, so will get them later.
Here's the rear mount seen from the underside.

The battery box isn't the only crooked part. The swingarm turned out to be too far off to work, so it's getting modified again. The lesson here is that the order of the welds is critical. Instead of welding in all the reference parts (the axle mounts and pivot tube) and then the reinforcement crossbar, I should have started at the axle and worked forward, welding in the crossbar next and the pivot tube last.

Well, here goes, again. The brake side of the swingarm needs to move out about 3/4 inch.

Most of the crossbar has to come out, as it would be really doglegged otherwise.

Results. Yes the wheel is off, but it's off by just the right amount. There's one more thing on the swingarm to fix, but that's a different operation.

And finally a gratuitous selfs portrait.
