I recently screwed up by ordering the wrong size tambour for a job. Before I call the customer in a couple of days to delay, does anyone have experience combining two sheets (of the same tambour)? I ordered 24” tambour (47” long slats) for several garage-type doors to replace in a boat. One of the doors is 28”. The doors slide laterally, and the slats sit vertically, in this application.
I have enough Tambour to piece another 4 inches onto the 24” section I’ve got. I’m not sure how to mend it in, though. Does anyone have any ideas? I’m past the point (time-wise and cost-wise), of making my own.
From contributor F:
I would do it right and order another roll of Tambour. The customer won't be happy even if you could splice it, and I'm sure you wouldn’t be either.
If the slats came off cleanly, as they usually do, I lay them out face up and put them in a squaring jig, which is just 2 boards nailed 90 degrees to each other to a sheet of melamine. Then use masking tape across them to hold the joints tight across the top, bottom and middle. Flip them over and spray with contact adhesive - I use 3M spray 90. Then spray the fabric. I spray it pretty heavy and let sit until it’s tacky, then apply the cloth to the tambour and then smooth it out and press them together as hard as I can. The result will be as good as you get from a manufacturer if you get the bonding right.
I bought a yard each of heavy/light duck cloth, laid up a few practice splices with TB, and 3M spray-on. Both glues performed the same, but the spray-on was infinitely more efficient – fast, clean, and no clamps or worries about slippage. I decided on a full-sized backer, with the light gauge cloth – the heavy cloth was just too thick over the existing cloth. I sprayed both sides, let them tack up, and it was spliced like new.
