With the correct flux & rod should be an easy job to do.

Have you already ordered it? For just a bit more you can get this.http://gasproducts.co.uk/gas-blow-torches/sievert-gas-blow-torch-kits.html

Its what I use and it makes 4" work easy. The handheld torches are good and I still have 3 that I use on smaller stuff.

I don't think you can get MAP anymore, they changed the mix of gas.

The higher temp gas is better but you still have the issue that the torch can only put out a certain "volume" of heat.

On bigger work that is more of a problem than the actual temperature. You just need to be able to pump in enough energy to get the entire joint up to temperature before you start applying solder.

Myles thank you so so much for jogging this old gray matter of mine. I already have one...you've saved me around £60/70 smackers



Totally forgot about the bugger...took some finding

I didn't think propane was hot enough for brazing??? and I'm not sure what size jet is fitted?? there's no numbers on it.

I've an empty butane bottle I'll see if I can change it for the same size propane.

I find propane plenty hot enough to braze silver solder, and I generally use 455 (630 to 660 °C).
I sometimes use 438 (650 to 720 °C) but don't generally need to use any of the higher temperature alloys.

I do sometimes use phosphorus alloys but only for structural use where it is not going to get hot. These alloys are really intended for use where they are going to get cold (refrigeration use) and are not supposed to be used in hot applications.

I don't know of your neck of the woods, or gas supplier, but locally to myself, Calor will change ANY empty bottle (of theirs) for ANY full one, any size, for the price of the gas.

It's the same here ED...I did swap years back a blue for a red. Will try it t'other way now.

My parrot has arrived.

Really pleased with the quality of the workmanship.

Just my 2 cents, I found using a parrot with a column less than helpful, it really is a tool for a pot still.

With a column the output ABV should be constant - you can pull tails at the end of a run at almost the same ABV as the mid-hearts. If you want to check the ABV much better filling a 100ml glass trial jar with the alcohol hydrometer.

I've found that column temps and take off speed are far better indicators when running a column, I run a VM which is much less fiddly than a CM like the T500 and the take off speed is the main thing I concentrate on - I aim to take off about 1.5l an hour, so I change my almost full pint jars ever 17 mins, I just set a timer on my phone, by the 3rd jar I have it dialed in and don't need to touch it again.
A CM will usually need more adjustment than that, but you get the idea.

Not planning to use it with the T500 column. I got it for use with the alembic dome and condenser, and because it looks nice!!

Ah I misunderstood, that will go the job then!
I use a larger bore tube 28mm as it lets me use my 70-100 and 40-70 range alcometers which are a bit chunkier that the full range ones
