radiator hose joining tube
whats the best way to join radiator hose? ive seen everthing from copper tube to stainless steel, what gauge does if have to be, also since plain tube
does not have any ridges to hold rubber tube over is there a problem from comming off under preasure, or is there any tricks to use.

Jaguar (on their xjs) used several pipes made from mild steel in between the rubber bits. the water filler is one example. After 15+ yeaers they can
rust out, but i doubt we keep cars that long.
I used a length of mild steel tube bought in straight lengths from a motor factors selling exhausts. weld a ridge on it or its very likely to blow off
the pipe.

Of use, and hand up anyone that looks at that pro beading tool in the foto and thinks "I can make one of them from a old mangle"

I have a "Model Engineering Workshop" article at home that tells you how to make a small jenny like that - trouble is, you need a lathe and heaps of
time that's better spent on building the Locost!
Seriously tho', I need a 6" long hose connector, for 32mm id hoses. Best I've seen is nearly £9 from Demon Tweeks - no way - time to get the lathe
running!

I used offcuts of stainless steel exhaust and its fine.
You don't need flares on the end as long as you use a pipe diameter thats a snug fit inside the hose and of course good hose clips. Pressure will not
blow it off!

Thats what I thought on my nice tight hoses until one blew off when i ran it in the garage.
Manufacturers put a ridge on there for a reason so i found.

It could have been worse, it could have been your oilcooler pipes on a bec blowing off, they DEFINATLY need flares on them.Oil on the tyres being
pumped out at pump pressure from the cooler oil gallery isnt fun.

I turned a hose connector from thick wall alloy tube to adapt from 32mm to 38mm and as it was 40mm od i was able to machine in the ridges on each end
. it fitted to the bottom hose great but now i need it to be a tee piece to allow me to connect the expansion bttle so will have to find some more
bar and weld in a tee.

You would definitely need flares on oil pipes - oil is a lubricant and at say 60psi you have a much different situation to water hoses.
I have built a number of cars over the years and plumbed many single seaters and have never had a water hose blow off. If you are running with more
than a couple of psi in the system you have probably got a different problem! Flares are better but I don't believe an absolute must. Just my
opinion.
