Securing stainless sink in workbench cutout

[bmwpower]

Finally cut my stainless top and inserted my stainless commerical sink into place. One question... what's the best way to secure the sink in the opening? I can caulk the front and side edges, but I'm wondering what else I could do to secure the sink.

The underside of my countertop is MDF. Should I make a flat brace, screw it to the underside of the countertop and attach the other end to the stainless sink via epoxy? The problem then becomes being able to remove the sink, if needed.

Any other ideas?

Typically you use plumbers putty around the perimeter and then there should be attachment clips that came with the sink to snug it down.

The putty I never heard of. That would help.

This sink is normally a floor standing model, so there are no clips. I took off the legs and dropped it in the cutout. This is what it looks like (with a stainless top in place of the temp wood top):

If the sink's normally meant to be freestanding, those clips (which would be the best/simplest/easiest way to attach it) probably won't work. Depends on how the edge of the sink is finished. If it's like a restaurant commercial sink and it rolls under and then back in on itself, you might be hard pressed to find something that will do what you want, but I bet there's somethign out there that will work. In any case, you want to clamp it to the top of your bench and then use plumbers putty to keep water from running underneath if you make a mess (or rather, roll out a snake of putty, set sink on it, then snug it down and wipe out the excess with a damp finger).

If the edge of the sink has any horizontal flat area at all underneath the lip, you could drill holes (carefully, just through the underside) and snug it down to the work surface with sheet metal screws.

That looks really nice, BMW!

That thing is likely heavy enough that the plumbers putty will be enough to hold it in place - it will "set up" after awhile and unless you really give it a good knock it isn't likely to break free. A smaller sink - like you have in a kitchen - doesn't have enough weight to keep it from moving.

I deal with this stuff everyday. Just use a commercial grade clear silicone and glue it wherever you can then finish it with a small bead around the edge. You would be very surprised at how strong clear silicone is.

Perhaps some 5200 adhesive from your local marine supply store would do the trick. Put a big bead on the bottom of the sink and set it into place. Not only will it hold, but it you will have to pry the sink up if you ever want to remove it. It's like caulk, but more adhesive.

go with the silicon - If you use 5200 you can count on never getting it out without ruining the counter and or the sink. I used that stuff for years to glue tuna towers and bow rails to boats.....when we had to remove something, it would often rip the gel coat off the boat.

Thanks guys for all the recommendations.

I ended up going with silicone around the rim. The problem with this sink is that the rim is thin since it's a rolled edge, so getting a good seal is tough, but I think I accomplished it.

I checked this morning and it seems to hold well.

That is a nice setup. Where did you get the sink?

Thanks for the compliment. I bought it used off of eBay.

I just got the same exact sink at a resturant supply here in Oakland. I was woundering the same thing. Although I dont have a cabnet to put it in yet. I had thought about welding on some tabs to tie it down with but I have never welded stainless yet. So Im not sure on the outcome.

The silicone appears to be working great. I bumped it a few times last night and it's solid. Time will tell...
