To freeze stuff use a spray can of compressed air from the hardware store….turn it upside down when you spray and the propellant will spray out and super cool your component
be careful with your fingers
this is the same technique you use when dropping a metal stock rudder that is stuck because the bearing has swollen , gripping the rudder stock
obviously you only chill the stock
I hate when that happens!OK, I'm an idiot!!!
I carefully clamped the entire thing a a drill press vise and started drilling with a Forstner bit. It was gong very well, but about half way through, the rubber sleeve began to push through the piece I was drilling.
Turns out there was a 1" ID sleeve outside the 3/4" ID sleeve.
Somebody was thinking, but it wasn't me.
Seekers suggestion is more appropriate. What you’re going to install will have limited longevity. (The plastic and rubber will deteriorate in the sun). So might as well make life easier for yourself. A strip of rubber or self amalgamating tape or whatever. Hopefully it’s not too heavy what your putting on. I note a lot of cruisers will mount outboard motors on their pulpit. Some seem to last ok. A few get stolen. Just need to ensure your pulpit is fit for purpose. Or you can follow El Borracho’s suggestion…Cut one out of a 1/8" thick sheet of rubber. Wrap it around the railing.
