tube fitting

[markg]

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?

forgot to say its a shakespeare 620 and tapered tube

Hi Mark

That is spot on, 130mm will be fine.

thanks kieron, first time tube fitter, i did have a good chat with ed when i collected the tubes but its hard to remember all of it

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.

cheers stephen, i can get the use of a heated workshop but i thought i might do a bit at home when i get chance,
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.

Sorry I really dont know - I wouldn't take my advice on hypalon repairs if I were you

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.
