I'm trying to find a source of s/s screw-on rubbing strips right now. Need them for the bow lines in the Med. Haven't found a catalog item yet, will probly have to have them custom made
One solution is a strip of "D" section brass. By my cleats for the permanent mooring ropes, I have added some opened up 1" transparent hose, and secured this to the GRP with some self tapers, but I have a nice lip that this hose can fit over. If the edge of the deck is flat, go for the D section brass.
Not sure of the exact situation but I am assuming that a piece of section such as half round won't do it, 'cos that is easy to obtain.
If a flat area then I just get a ss fabricator to cut a piece the size and shape I want - only needs to be very thin. If it needs to fold over a corner, such as on a coaming or whatever, I just make up a template of the angle and any radius on the bend (cardboard, ply, whatever) and get a ss fabricator to cut it and fold it. Usually very cheap as only takes them a few minutes and much easier than trying to do it oneself. I tidy up the edges and polish it.
In both cases there is no need to screw or bolt the sheet on, Sika 291 or similar will hold it down no problems at all (may have to weight while setting so's the ss flexes to the exact shape of the underlying structure if that is not dead flat).
I am not in the UK Phil so can't be of much specific help on where to get half rounds. It is available in UK as these guys http://www.bridonstocksbridge.com/products.htm (see picture about 3/4 way down right hand side of page) in Sheffield manufacture it but I doubt they would supply a short piece.
SS/non ferrous metal stockists would be the first call, but possibly a kitchen equipment, medical equipment or architectural fabricator if any close by may sell you a short bit, rather than a length, if they have it. Failing that flat bar is easier to obtain (any non ferrous metal stockist/ss fabricator should have it, probably in 316 as well though not essential) and the edges of that could be ground to a radius and polished, assuming you only had a short piece or two to do.
Ive heard of a 3M product which is basically a piece of stick on plastic which covers the area which is being worn away.
Need to replace it occasionally. PM Dom, I think it was he who told me.
