Dual tank? Modifications

[Steve]

I think that if you leave the back of the tank almost unmolested, like your diagram shows, gas will flow across the back just like it does on the stock tank.

I don't see why you would need to add the second petcock.

I was highly skeptical when you were describing your project in the first post, but I really like the direction it is heading.

If you can do it then heck yeah! It will look more like a harley tank.

Is this for the sake of appearance or you are looking for more fuel capacity?

[ValorSolo]

Appearance and capacity are secondary reasons behind this idea.
The act of modifying and originality are the main culprits.
And the tank is in need of proper repairs.
I also want to add dual petcocks and a fuel gauge sending unit.

Basically, I just want to do it.
I have the know-how and ability.
And really haven't found any reasons not to do it.
I don't think the appearance will be drastically altered, only slightly.
The capacity should increase considerably, though.

The logical side of my brain is forcing me to hold off until I have a replacement.
But the other half is quite rebellious and in a hurry to get started.
Looking back on my life, I'd say logic rarely wins, but more frequently now with age.

Anyone ever used a chrome paint called alclad?
From what I've gathered, it's made to chrome plastics, not sure if it works for metal.

I still haven't found out much about this. I think I'll try it on the gas cap cover.

I'll be following this one, I've been contemplating the same thing with a spare leaky tank I have, what kind of welder will you be using to weld the tank back together, do you have access to all the sheet metal fab equipment?

[ValorSolo]

I have a wire-feed and two arc welders. I'll be using the wire-feed on the tank.
Proper cutting should eliminate the need for anything other than a hammer to shape the metal.
It'll also make the welding and smoothing/sanding less of a chore.
I sure hope I can locate my nibbler, using hand snips will be brutal for this much cutting.
Other than a hammer, anvil and nibbler, I'll be using a side grinder to dress the edges and smooth the welds.
If I were building a tank from scratch, I'd most like want a decent folding tool, seamer and notching tool.

post a pick of your nibbler when you can

[ValorSolo]

Mine is actually pneumatic. I burnt up too many of the electric ones .
And the air nibbler will cut stuff that the electric can't come close to handling.

I haven't seen mine since I quit working on the road, haven't needed it, either.
I'm hoping my brother borrowed it or it's in my old gang box.

[old_skool]

I believe this is a metal nibbler. Look may vary. Might even be electric.

Gotcha. I had an air hammer with a bit that worked the same way, I wouldn't mind getting a hand operated one for thin sheet metal small work.

DeWalt has a 18-volt cordless nibbler that works pretty good.

If you are splitting the tank into three parts, you might hunt down a later tank that had a sending unit. I think the 1979 GS750 (1980 maybe?) had the same tank but with a fuel gauge sending unit. If so, grab one of those off ebay and swap that side from the old tank when you reassemble your Voltron tank.

[ValorSolo]

I have a sender from a GSX750. I may have to bend the float arm to adjust it, but it should work.

[ValorSolo]

Still waiting on a replacement tank. But I did get a sender from a GSX750.
I'm also looking to buy a tach that has a fuel gauge in the bottom.
Waiting for another tank before cutting this one is not easy.
I'm ready to get a tank, any tank, on my bike and ride.
And it looks like I could have this one ready before a replacement will arrive.

[ValorSolo]

Well I couldn't wait any longer. I cut open my tank yesterday.
After getting it apart, I was able to get to the dents with a hammer.
They smoothed out just fine, with little effort.

I was also able to find a good placement for the sender and adjust it properly.
I'll still have to weld in some mounting nuts and make a gasket.

I've scratch the second petcock, simply because I only have one petcock on hand.
It's really not needed, so no need to spend the time and money to get another one.

I'll post some pictures after I clean all the pieces and get them laid out.
