Protection for catalytic converter with chain
So, ive been having problems with thieves stealing the catalytic converter from our warehouse. You can buy plate and such and anchor but they are expensive and i want to do something cheap.
My idea is to use GRADE 8 chain and wrap it around like a snake and weld it directly to the exhaust.
My question is what steps would i need to do to make sure it bonds well?
Would it be better to use a lower grade chain because GRADE 8 is strong?
Do i need a heating element to get the chain hot before i weld it?

You engineer this by yourself or have help?

Nothing stops a thief. That chain will add some time to their cut time. Plus that's a lot of weight for the exhaust system to carry.

So the zip wheel they use to cut off the cat won't cut through chain?

A chain link catalytic converter would be a good match for a chain link steering wheel

Re: Protection for catalytic converter with chain
A 9,000 volt coil out microwave will stop them but may have legal problems for you after they try steeling the catalytic converter.

Re: Protection for catalytic converter with chain
Someone correct me if I'm wrong, but the OP mentioned Grade 8 chain. Chains come in grades like 40, 50, 60, 70, 80, etc. Bolts in single grades like 6, 7, 8,......Never saw a Grade 8 chain. Must be really soft

12 gauge with rock salt.
Thieves don't wanna F with the crazy guy that jumps out of the shadows shooting at them with a shotgun.
Wonder what the laws are regarding CS gas. That'd be kinda fun, too.
