JB Weld and Ferric?

I have a little non knife project I’m working on for an Xmas present. I forged a Damascus wine cork screw. To attach the screw to the handle I did a square end in square hole with a peened top for mechanical hold. There is still some play of the handle up and down on the shaft, so I plan to JB Weld it on for security and seal up any gaps. I am trying to decide if I should JB weld before or after the ferric etch. Before would keep any acid from getting trapped up in the gaps that will be tricky to neutralize, but I don’t know if the ferric will break down the JB weld?

I agree with Bill tat a good fit is better than a good patch. Soldering is also an option.

To answer your question, cured JB-Weld should not be affected by FC.
 
In hindsight I should have ground in a step to give some backing when riveting the top or at least a more aggressive taper. Unfortunately I only put in a very slight taper, which combined with not having a proper vise caused some issues getting everything tight mechanically. I’ll give some thought to the solder option. I did harden it so as not to have the shaft bend or the screw uncoil in use, so I have some concerns about the temper soldering. I know it should be feasible to be ok because many solder on guards, but it’s not a skill I’m well practiced at yet. Thanks guys.

Im not sure ... my initial thought is that JB Weld is impregnated with metal ... and so even if cured, the exposed metal on the surface of the resin might etch and look bad? Just a guess though.

i would consider soldering. If you have not done soldering in the past ( copper piping? Electronics? Craftwork?) then get some scrap pieces and practice getting a feel for getting the work piece up to temp so ad to get the solder to flow. Ithink if you are careful not to overheat you will be fine with the temper on the screw - especially if you wrap it in a wet cloth. But now that i think about it you might have issues with twisting at the junction with the handle ... so am not so sure?
 
JB-weld is an epoxy resin compound with inert fillers. You may be thinking of the old "Liquid Steel".
