Sirius: Alco "Firefly" version

Jasonb:
The Garden or "patio gas" is propane but I've only ever seen then with a clip on type fitting and all the regulators for that are low pressure so you won't get the heat out of the gun which would take us back to square 1

Sanjay F:
All sorted - I now have an orange bottle, with screw connector which I checked has the same thread as the regulator. I'll hook it all up and have a new attempt at soldering ........ if you don't hear from me, things haven't gone well   :ROFL:

AVTUR:
I use a Sievert 3488 handle which includes a low flow gas setting. Once it is set up with just the slightest of pilot flow and no main flow it can be safely lit with a match.

Two words of warning: Alway use spanners to do up the unions, particularly on the handle. A hose failure valve should be used downstream of the regualtor. Putting the torch flame through the gas supply line would be very interesting.

Propane torches can give out a lot of heat. I do all my silver soldering outside. Too many things can catch fire in a workshop. Think about what you are wearing. Oily cotton overalls are not a good idea. Again I have a welder's glove on my non-dominant hand. Also, Propane bottles should stored outside.

Given the above, silver soldering is a very satisfying occupation. You may meet all sorts of interesting problems. Have fun and I hope you progress on to heat treatment.

Sanjay F:
Thanks for all the valuable advice, I'll check all the connectors and do the soap trick to ensure a good seal. I have sparker arriving tomorrow so it will probably be the weekend before I give it a try.

I'm looking forward to it, I enjoy learning new practical skills, especially as I sit in front of a computer all day wishing I was in the workshop  ;)

Sanjay F:
I'm finding all sorts of interesting things on this engine

- The conrods halves have matching numbers stamped on them
- Like a car the engine and 'chassis' have serial numbers which also match

I found an appropriately sized pressure gauge to replace the missing one, but was looking very shinny, so aged it with some bicarbonate of soda and tea  :)
