Chevrolet coolant condensor can

[Mike Cecil]

The top and bottom joins are rolled edges - done with a set of two shaped rollers in a top & bottom seamer that clamps the top and bottom in place against the rolled edges of the body. First stroke rolls the body edge over the top of the top (or bottom depending which way up it is), the second stroke flattens it against the side of the clamping plate at top. Each end is done individually.

The top and bottom pressings are round with a depressed edge all round.

The body is a rectangle of sheet steel with the points notched, ie cut at an angle, so that they don't catch or foul the edge roller when rolling the top & bottom edges.

Same manufacturing technique as making the great Aussie 'Billy' can, and I've made plenty of them during my senior school and university breaks. Of course, that is with the right machinery for the job, but if only making one or two, Grant's methodology and tooling sounds fine.

Excellent info, guys! I have moved this thread over to the restoration forum.

Who's going to have a run of these cans made? I am good for one, I'm sure there are many others in need as these tanks seem to be missing most of the time.

Hi Mariano, yes they all had an overflow tank. Cab 13s , at least.
Earlier ones had the tank on the left front fender, later ones had them fitted under the mudguard.

My impression is that although the style of construction is very similar to the Chevrolet CMP condenser can, the reproductions are taller in relation to their diameter than the CMP can. I would love to be proven wrong because as I see it, there's a fair bit of work involved to make a functioning close mock-up. The originals were made with a multi-fold roll-formed lock seam around top and bottom (like tin cans) that I can't reproduce - I would be simplifying the fold structure.

....at finding the old hand cranked canning machines.......

Now who, besides Charlie Down, can tell us the dimensions of the huge condenser tanks/cans used on the running board of F30 LRDG.....right side behind the driver????

....and by the way.....early production cab 11 did not have a condenser tank and the external side body panel ( but may have been retro fitted) was not even drilled for the rubber hose.... also no rubber marker lights on the fenders as they relied on the small internal light on the headlight reflector....

I installed a skinny stainless steel tank designed for hot rods on my cab 11....sandblasted and painted OD totally hidden in the inside crease of the radiator frame and left front fender..... holds about a litre + and works!!!!!
