1961 Caper Cycle Falcon Resto

#1
Hey all,

I posted in the wanted section for an engine for this but I thought I’d start a slow rolling thread on it. Found this today:
4AC1D459-B3C8-4FB5-95DA-0678D26FBF7D.jpeg
I wanna say this is ‘85? ‘86? Just because of the Dire Straits Brothers in Arms shirt but it could have been a little later I suppose. That’s me on my bike in the hood. At this point, it had a manual rope pull 3hp Briggs on it. I think back to cruising down that hill and locking up the brake and sliding into the driveway…. If only I’d know how impossible it would become to find those tires!
Anyway, back then I didn’t even know what make it was. If you zoom in on where the decal would be, it had long since been painted over…. Till a few months back:

I pulled the old DYMO labels off and the aluminum flashing tape behind it and voila:

I’d been screwing about with getting it running and decided to take the engine (now a super low hour Briggs 6B-S) off and keep it as, I dunno, one more in the Briggs collection, I guess? and get the caper cycle back to its original glory.

As it sits, it’s a solid straight frame. Everything is functional if not tight… tho I’m sure a going over with the blasting media will expose something.

I’ll probably reuse the tires, they’re a bit slicked but they’re not dry or cracked. Biggest PITA will the be engine (West Bend 700) and the seat…. But again, we’ll see what the media blaster tells us.

Anyway, looking forward to tearing in!

Starting the tears down with some stuff that’s not integral to its function. Namely, it’s original gas tank.
69031E4A-E2CA-44F5-BBDE-C5103F570449.jpeg It was always sort of a mystery to me, having never seen it with its original mill, why this tank was on it. I grew to love the balance of it, if only visually. Plus my father had told me about Palmini being some Kart/bike hop up company so I kinda felt a little more bad ass only having the gas cap.
Anyhow, it’s time to get it in shape to supply juice to the bikes next mill and that’s gonna take some soaking, shaking and rinsing… and some gentle dent removal.

Getting further into the tank: I’d found some pitting in the bottom around the screen which, due to the thinness of the material, I assumed were holes:
BB7FAE33-4F4F-4E4A-AC60-D4229217F7CB.jpeg
which they turned out to be. However, putting a little heat on the valve lug, the whole thing just popped out. Later, I noticed some flex in the tank seam, like the entire bottom half:
62A39412-6032-47F5-9CFB-191B0E181CCD.jpeg
so these were two half’s simply sweated together? I mean, that’s sort of awesome as mig or tiging them together would be a nightmare but. Having “lightly secured” flammable liquid that close to my ass and an exhaust riser seems, well, chilling.
Anyway, guess popping the dents out just got a ton easier!

I believe most of the older metal tanks were brazed or solderd together. I've been told some tanks will come apart in the oven during powder coating. Nice old bike you have there, it will be a nice rider when you're finished.

My history in metal work is pretty spotty… generally to decent ends, I never taught myself welding or sheet good working, roughing it into shape and relying on my eye during full sanding was good enough.
This was as good of an excuse as any to try my hand at hammers and dollys.

It’s not actually snotted back together yet, I still have some patch work to do in the bottom, but the dents are satisfactorily removed minus a few sharp gouges that’ll need red led before the final finish.

after the grinder grabbed half of it and flung it across the room at my bike stand (this is after I first beat all the dents out and before the second time I beat all the dents out) I was looking for some options online… 150 bucks for an aluminum tank. That’s fine but .. I’d rather put that in the engine fund.

Wow that's an inspiring old b&w pic. It kinda looks like a modern day build!

So, brazing or sweating solder? Having no experience with either, I'm interested to see how you bring it back together. Nice work on the tank!

Thanks! I got the pinholes sealed up today. Gonna let it sit the night then I’ll work on soldering everything back together. I guess we’ll see how all that goes!
