heres a simple tip if you want to check for leaks if you are concerned about it.
once everything is conected.
make up a weak soapy solution in a hand sprayer.
open the valve on the bottle and a little spray on each joint.
a gas leak will show up as lots of bubbles.
dont ever be tempted to use grease or oil on the threads very very dengerous.

Whilst on the subject of torches, I'd like to remind newbee's of the mouth blow torch, which is the traditional jewellers torch.

They run off a single gas, usually butane, but will accept propane (do check before buying) or natural gas. The air is supplied via blowing into a tube connected to it, and they are much much lower gas pressure than sievert or similar propane torch.

Though many torches will cross over and do similar jobs, traditionaly to my mind, seivert and similar torches are for silversmiths, wishing to solder on tankard handles, where real power with a broad flame is needed, although many use them with complete success for jewellery tasks.

So just thought i'd remind folks, about the mouth blow torch, as its often overlooked, or not understood, so not purchased.

Absolutely agree Ben , very good advice.

the 3939 nozzle is a good alrounder if you have the needle point nozzle.
you will need to get another neck tube to go with it though.

is that big enough for it? in the delft demo videos here he's using a nozzle like an inch across? sorry for being such a pain in the bum
