Title: Tank brackets
Post by: Dennis Heckel on March 24, 2009, 04:45:02 PM

Have any of you tried Jb weld on tank brackets instead of soldering them?

It doesn't seem to me like it would be as strong but it would be easier.

I tried JB weld to an aluminum tank bracket and it held fine to the aluminum, but not to the tank. It did not stick to the tin tank at all. The aluminum bracket was about 1-3/4" wide and JB welded to the middle of the tank.

There's probably nothing better than solder, but it seems if you scuffed both surfaces(BRASS bracket and tank back) with 600 grit sandpaper and cleaned it with alcohol (remove all residual oils) JB should hold it.Might check your rear seam of the tank for leaks before doing it. I have built mufflers with JB weld (alluminum to alloy joints) and  holds up well. If you solder, pressure test it with your empty fuel syringe, plug the vents, and submerge it in a bowl of water.

Just my experience...

Yeah, seemed like a good idea to me, too. Tried scuffing both surfaces - no go. Solder is, I think, the only way. Back to the old bent music wire and rubber bands . . .

Very small screw eyes cut to make hooks out of them, rubber bands and a piece of foam rubber under the tank for vibration control. Easily removed and replaced for cleaning and maint., adjustable too.

I went over to cotton cordell lure makers to see if I could buy some of those small screw eyes they use in fishing lures...they handed me about a thousand and said no charge...I gave them $10 and left feeling like a bandit! ;D

I have been using scrapps of Nyrod ( the inner yelow rod). Put a piece of foam pad behind the tank, wrap the nyrod around the outside of the tank and use 2-56 screws through the fuse. I have had severl bad crashes and not damaged the tank or the mount. The soldered on mounts usually tear the tanks up in a crash.

Bend up a tank?  In a crash?

What's that all about?

Nah, the cool part about soldering is mental.  As you apply too much or too little heat, you wonder why it wasn't just called sodder.  Perhaps in reverence to those that would lift grass and fit it neatly in your mom in law's yard and remind her to keep it watered.

And then there was the tenth President, John Tyler.  Who laid tile in bathrooms in his earlly days.

Gotta go!  Doc is coming.

Ok

Looks like either solder or screw eyes and rubber bands.

Thanks for all the advice.
