Ideal amount of solder in a joint

That's understandable then. If you are provided with them, fair enough.

I'm sure you are familiar with the type of customer who wants to buy everything him/herself

i read somewhere (think it was copper guild?)
15mm pipe needs 15mm 3.5 solder wire. 22mm = 22mm!

i lay my solder across the joint until it melts and runs and thats it !!

I've tried various ways to try and perfect my soldering.. and so far, the best method I now use is to heat the fitting and solder from back of joint til I see it come round the front. If it's a vertical fitting, I usually feed from top at the back, keep heating the fitting til I see it run a ring at the bottom of the fitting.

If it's under the floor I usually solder the **** out of all fittings lol

I can never understand why a lot of plumbers heat the fittings with powerful flame until they go black? Only tarnishes the copper preventing solder joining and burns the flux away and runs solder out of the fittings.
The fitting will have soldered fully with just a slight extra heat just beyond when you see solder melting and flowing around the joint. I used butane gas for years on 15mm up to 28mm soldering and it normally was plenty of power, so propane powered Surefire 2 torches many now use, including myself, should be more than enough to overheat an average joint if not careful.
I put my hands up to admit my method of soldering is to flux the pipe but also very slight smear on inside of fitting. I also slightly overheat the fitting (as definitely want to avoid under heating it) and I add solder to any Yorkshire fittings as it confirms the whole joint is soldered and won't do any harm, especially if some of the fittings solder has run out while heating. I prefer end feed for most jobs though.

Yes. It's usually a load of stuff from Hong Kong that they found on Ebay.
