As above, wary/leery of using polyester 'metal in a tube'
Newbie, small project, cant get devcote or the other well known brands here. Will fibreglass used for surf board repairs or ship repairs be ok?
Thanks in advance
 
I have used J-B Weld to bed actions for several years.
It may not be as hard as some other bedding compounds but is easy to work with and does a good job.
Always mix slightly more hardened than steel and wax your metal parts for a good release. I use clear TREWAX, it is a paste, apply and buff off repeatedly till you have enought buildup to make it release.

You can practice with a piece of wood and scrap metal.
 
J-B Weld and its product called Industroweld work fine for bedding and gluing both. The J-B product page will give more info. Just 2 things about the A-B stuff, 1) it is slightly thin and runny if you are filing in big areas that are not horizontal and 2) do not use the quick set J-B or any of the quick set/5-minute products by any of the epoxy manufacturers. They all have much less high temperature tolerance than the normal set products.

You have several options..

Polyester resin is what is commonly called fiberglass.
It uses MEK peroxide as a catalyst/hardner. ten drops hardner per 1 oz resin.


Epoxy is to two part mix. One called epoxy resin and the other called epoxy hardner. Usually a 50/50 mix.

JB weld is epoxy based with a filler.

Thanks Guys.
What I have here is something called Permatex. liquid metal filler 100g tube.setting time is 4-5 hrs
Contains bari um sulfate, acetone, kaolin,vinyl resin and butyl acetate.
Obviously known to the state of california to cause cancer...:eek:

Thought its soft and should be ok for a 22RF.If its a nada,then will go back to JBWELD which I could pick up from the local autobarn , here in smalltown, Oz

I've successfly used JB to do my first minor bedding job. I was using an already bedded stock and was adding some more bedding to it in "skim bedding" style. But if you can work around the runniness of it, then yea, it ought to be good enough for large areas too.

Like mentioned elsewhere, be sure to mix it properly, or if anything....then go and add a tad more hardener to the mix then the epoxy resin. And DON'T trust the tubes to have equal amounts. I used a small cough medicine measuring cup to mix out exactly half from each tube, and I observed that one tube had a lot more left over in it then the other tube.
 
promise not to use any of the above mentioned to do my bedding:)
Thanks for the info, appreciate it
