Drop in sink woes

[RashidAli]

Hello All,

I bought a sink at a second hand store. It didn't have a U-channel, but had several bolts that were epoxied to the underside. I went ahead and used the sink as a template and cut out the counter for the sink and it fits like a glove. Turns out the bolts are not long enough to extend past the counter underneath to provide any sort of hold to keep the sink down.

Would I be able to use silicone to mount the sink to the top of the counter, then silicone it around the base, and keep it secure enough with all the jostling a vehicle has?

Or should I try to remove the bolt/epoxy and replace them with longer bolt and secure it that way? I would probably would use some scrap plywood and nylon locking bolts to keep it tight if this route would be better.

look into rod coupling/rod extensions.
then you get some rod,nuts and washers and make the existing one the length you want.

pictures would be helpful, but yes, use threaded couplings and make use of the existing bolts if they will hold, don't rely on adhesive alone.

Besides, it's good practice for those other, more nasty jobs where you will be sorely tempted (and seriously sorry) for taking the shortcut. Discipline!

You could try
The extensions. Look For “standoffs” At your local hardware store like Ace. If you don’t have the hooks then that’s not going to work.

You could just glue it in place, use urethane adhesive and fill the sink with a bunch of canned goods or something else heavy
