what is holding sink in place?

[timangiel]

I have a stainless steel sink in my galley that I want to remove. I am familiar with the manner in which sinks are installed in a house, with metal clips on the underside of the countertop. When I took a look under this sink I did not see any kind of clip or fastner on the under side. Do they glue sinks in place?, and if so how do you remove them? Its a boat from the late 70's and I'm pretty sure its original.

mine was held on by silicon sealant, which I had to separate from the countertop with a hammer and scraper/chisel; as well as some metal clips

My '73 Morgan has the metal clips on the underside of the countertop as you descibed. What do you find when you run a thin blade under the lip of the sink at the top of the counter? Take care and joy, Aythya crew

If there are no clips then it's probably just caulked in place, and the plumbing conection under the sink for the drain helps hold the sink down.

If it's glued in, then start in one corner with a few putty knives/butter knives, wedging them on top of ea. other. between the sink and counter. then slide a thicker screwdriver in between them to act as a wedge and use a long razor knife to cut the seal as you work around the whole sink.

I'm still hunting for the person who installed the sink on my Cat 36. The sink has a lip which sits on the fiberglass liner, then the countertop was laid on top. I have a beautiful new sink to replace it (it's rusty) and I'm gonna have to CUT it out. Fun fun.

You might be able to cut it out from the bottom side with something like a Rotozip or maybe even a Dremel (keeping the top side hole the same), but I'm pretty sure you can do it from the top side if you take the fawcet off...but then you have to use a slightly larger sink for the larger hole.

I don't know how I missed it previously, but after getting back down to the boat and taking a good look with a flashlight, I noticed a washer and nut on the underside of the countertop near each corner of the sink. So, I removed them and the sink came right out. The sink had threaded studs at each corner on the under side of the lip that prodruded through holes drilled into the counter top. They were hard to see due to some very tight spaces.

Yes, I can cut it from the top, no room from underneath. The new sink has a lip which will sit on the countertop and allow plenty of support all around. I haven't decided if a Dremel will cut the Stainless or if I need an angle grinder with cutting blade. I'm still summoning up my courage for this job.

Try to find a "Cobalt" cutter for a Dremel/Roto zip, regular bits wont really cut well.

A high speed metal cutting blade (the thin ones) on a high speed grinder will do it. Don't use a slow speed blade on a high speed grinder since they can blow apart.
