Topic: Has anyone cut the tank lip?

[tekkie]

Is there any reason why this cannot be done? It annoys the heck out of me, it just looks so silly with the aftermarket seat

Plan is obviously clean the tank , grind it off and the tig weld anything that needs to be fixed

[540nova]

If you grind it off, you'll be tig welding the whole seam. That's what connects the upper and lower halves.

The metal is a decent thickness so it shouldn’t be to big of a deal to do that even if I am new to tig lol

[tekkie]

Better yet I think I am going to put a piece of metal to fill that spot so the tank continues all the way down

Then for the tank I will weld a nut and then have a bolt that goes up from the bottom to hold it in place

I can't speak for your welding skills, but, boy, I think I'd want a really good welder to do that for me.  Even the tiniest pinholes or burn throughs are going to be a pain.  What you want to do will look really nice with that seat combo, but I can't imagine a really good welder charging a lot to do it safely and correctly.

 And remember to not blow yourself up. Maybe a little body filler would smooth out the tail of the tank.

[RAFster122s]

Could crest a filler piece that keeps the tank stock and fills the gap for the seat. A bit of swiss cheesed metal to serve as a bolt down device and you could slowly build it from Bondo. Trying to do it all in one swipe will lead to a part that takes forever to cure and it will likely crack. Why didn't you have the seat fill that area to abutt the tank? Or, is that seat an off the shelve generic?

[tekkie]

yeah it turned out to be more than i bargined for lol even at 10 amps its burning the metal very easily

i am ordering some smaller filler rods and if that doesn't work i will be taking it to someone familiar with body panels

the seat is a generic one that is designed for the cafe base

[RAFster122s]

You do know to tack it and work in small areas to keep from warping metal?

Godfrey does Tank work and is quite good at it.

thanks for the tip i just ordered some of the silicon bronze

i test welded on the 20g that i was adding and i welded that no problem at 50 amps

i will play around after the other wire gets here

hoping to not use any bondo at all

yeah i was tacking it

good call if i cant sort it out i may ask him

[540nova]

It would be cheaper and easier to change the seat. That one on now doesn't look like anything special,  anyway.

540nova, too late for that tank, he already cut the lip off.will he finish it is the question? Hope so.

it will get finished one way or another

Its easier to work with foam IMHO , i used a hard vinyl top padding ( sandable ) to get that extra distance to the tank and get a smooth line . Nice and firm and i used memory foam on the rear bump so it can be used as a seat if necessary.  Stock pan also !

[johans]

I was just pointing out what can be done to the front of the seat blending into the tank.  Doing the same thing on a 76 SS with a 78K tank now ( big gap ) , i personally like the wider tank .

agreed that doing the seat would have been easier, but I always like to make easy things more complicated than they need to be lol
