Mini alternator kits for nostalgia drag racing.
There are three different kits available, one which caters to the small block Chevrolet crowd, one for the 348/409 racers and of course the Mark IV Chevy big block series.
What these offered was a relocation to the original power steering location, a deep grooved pulley on the alternator and a 65 amp alternator that weighs in at about half the weight of the 35 amp AC Delco units.
The smaller size of the one wire Denso alternators allows them to fit where the steering pumps used to reside.
My kits eliminate the flimsy stamped bracketry in favor of substantial 3/8ths inch 6061 T6 ones too.
Each kit was delivered with a hardware package, so all that was necessary was the install and a one wire hookup to use them.
?
I also provided a deep grooved? 5 inch diameter crankshaft in the kits that slows the alternators down.
That gives you back a little of the power lost from winding one up.
The smaller unit saves space, withstands higher revs better and has about twice the output of the AC Delco units.

The welder cost under $20 USD and we had already bought it for battery packs.

Looks like batches of a dozen at a time, don't know how many.? First batch is out for market test.

For larger number look for company that does for advertising.?

Thin was just hobby in one's and two's and level is different set of problems.? This one I a roll of very strong silver well solder bandsaw? blades and a low temperature silver solder. Both Great for a few parts.

Hard to hit a 2mm diameter rod with a mig welder.? The rod is only twice the size of the mig wire.

Maybe pug welding inthat gauge.

Spot welders are great tool? but heavy gauges takes a lot amps in thousands amps to do weld correctly.??

We've got a bunch of sheet metal clips to attach to 2mm stainless steel rods.? Hmm, how to do this.

Then I hit on it.? We have a Docreate spot welder for making up battery packs (like 18650 cells).

I dialed it up to FULL POWER and tried it.? Even without cleaning the metal I got a decent weld, couldn't pull it apart by hand using moderate force (any more and other things would break).

So, spot welding it is.

That Docreate welder seems like a nice machine.? Well thought out and works.? We haven't had it too long so can't say how well it lasts, but it also wasn't expensive.? They sell a range of welders, here's the one we have

Re: My project thread

 

That fantastic?
Congratulations on passing.??
We need inspectors it is a pain waiting for inspection but is very need.?
?
Sounds like you work steel
?
This has nothing with boilers. The Northridge earthquake found thousands of shops using solids on buildings. Since the late 1970’s California ban use of solid mig wire on buildings. The next big one was bad welds found on buildings and bridges. FYI I have both buildings and hangar doors in? LA area and all my shop's? work pass the xray and other test. My shop follow all rules.?

Keep up the good work on inspection it is very need to keep us safe. ?

Re: My project thread

 

That project was finished last summer.
We passed our boiler inspection with flying colors afterwards.
We also wrote g code to make future ones out of steel plate.
?
The new breed of pressure vessel inspectors are unaware that all riveted boilers leaked until they were first fired, when rust and calcification took over and finished the seal.
Had they let us fire it first, it would have probably fixed itself.
?
Next up is to look into getting approval to manufacture steam boiler injection pumps.
The machinework is simple, it's the bureaucracy that creates the bottleneck.
