tube fitting

just cutting out the fabric strips to fit the tubes , i have done the inner ones but cant remember what width the strips underneath should be
there is a 60mm sanded strip all along the underside of the tube flange and the flange is 10mm thick so i figured 60mm on the flange and tube and 10mm to allow for the width of the flange makeing a 130mm wide fabric strip does this seem about right?

Hi Mark

That is spot on, 130mm will be fine.

hypalon glue, would it be ok to use outside under cover or does it need a bit higher temp? activator to glue is about 50-1 mix, could it be mixed a little stronger to use outside?
how susceptible is it to humidity?
could i key the fitting strips a few days in advance and then wipe down with toluene just before fitting or do they need to be fitted pretty quick after prep?
thanks for any tips, mark.

What I was told when attempting my repairs was a warm temp (20 deg ish) and low humidity were essential. I didn't have either, which was probably part of the problem. Unless you live in the Sahara, outside repairs could be a problem. Having said that I have done a couple of smaller patches in other places with no problem, always tried to do it with sun on the tubes to keep it warm.

would it be ok to prep the fitting strips a few days in advance?

When some kind soul stuck a knife in my sponson I had to do an outer and inner patch during the winter. I did it in 12 degrees or less (was dry though) and it is still holding without any leaks 4 years later.

i have inflated the tubes and put them on the flange ready to mark up, logic says i can buff up the tubes and fitting strips as long as i keep them clean and then wipe them down with toluene when i get access to my mates heated workshop,
if its only the glue affected by temp and humidity, any preparation i do should be fine as long as its clean when glue goes on, just trying to get as much prep done as i can beforehand, cheers, mark.
