fab question - I need to make/buy a thin SS half round tube
we got a stainless steel farm style sink in the kitchen. There's no
counter edge on the front of the sink so any splashes that land on the sink deck run off the front edge onto the floor. For a pretty expensive sink, it's not a good design. My idea to fix this is to get a 3 ft "half round" of ss tubing, maybe with a 1/8" or 3/16" radius (1/4" to 3/8 diam tube before slitting) and fill the inside of the half-round with silicone and glue it down to the sink deck just to make a little "speed bump" to stop the water. I figure if the edge is straight, then there should be no glue visible. Of course the problem is how to get or fab this. Any ideas? |

fab question - I need to make/buy a thin SS half round tube
I would form a piece of flat stock.
In a piece of IPE (ironwood) use a router with a ball end tool to form the female die. Use a round over bit to form the male punch, with a little clearance. Place SS sheet over die and C clamp forcing SS into the female die. Machining off half of a SS tube is a real PITA, and you will likely find that the residual stress in the tube will cause significant bend in the machined part.

fab question - I need to make/buy a thin SS half round tube
Thanks, that's a good suggestion. I suppose I could also use a solid
half round and attach it with some type of adhesive. But at 1/4" diameter there would not be much glue surface. But since cutting anything lengthwise for 3 or 4 feet will be a real problem, I think I need to either buy it in the right profile or form flat stock as suggested.

fab question - I need to make/buy a thin SS half round tube
i think you picked a tough one. i think if it were me i'd settle for a
fiberglass rod filed/shaped into a half round. or a strip of that 3M autobody trim adhesive tape or something like that. seems like getting a 3/8" stainless tube slit in half is a toughie. i mean, it's a simple pretty solution and all but whew, rough to do. i looked at thomasnet.com but i think you'd have to buy a truck load of stuff to order from those corporations. www.mcmaster.com has stainless half round rods 1267T51, i think reasonably priced, good luck getting a 6' long 1/2" rod delivered without being totally ****ed up and bent. :-) also, it specifies "annealed", if it were me i'd call and make sure it's STRAIGHT. seems like annealed rod could already be snakey. i think getting (cold rolled) steel in half round would be not-impossible, but then you'd have to get it plated or something. there was nickel and silver and copper half rounds on the internet but that would probably not be practical. i know even the mcmaster half round isn't to your spec, (1/2" instead of 1/4"), but at least it's only 1/4" tall. and you can round over the ends for a finished look. glue it w/ silicone or epoxy or sumpthin'. good luck. b.w.

Not the exact dimensions you asked for, but it was the second Google hit for: "stainless steel" "rub rail" http://www.tacomarine.com/cat--Stain...olid_back.html A deeper search may turn up something closer. If not, it would be easier to modify that stuff than start from scratch. -- Ned Simmons |
