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

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!!

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.

My parrot has arrived.

Really pleased with the quality of the workmanship.

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

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.

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.

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.

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

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.

Once you start joining pieces of copper, you will discover how easy that is..

He's right, give it a go.

Over the years I've done plenty of DIY domestic plumbing, almost entirely in 15mm, and mostly using solder ring connections. This is my first ever attempt at metal bashing and freeform soldering.

image.jpg

So I found some 22mm pipe and polished it up a bit, then I cut off a couple of pieces, snipped them lengthways, opened them out by running an axe head down the crack and hammered them flat.

Found a cone generation utility on i-logic.com/conecalc and marked out on what was the inside of the tube. Turned a taper onto a chunk of an old oak table leg to bash the cones around.

Needs a good bit of cleaning up, but it's watertight and I'm pretty pleased with my efforts.

Just need to bore a hole in another nice piece of oak to stand it in now. That should be the easy bit, except I've got nothing between 20 and 25mm drill bits. Sodding typical!

Hum? see I tried with something similar Brian, but it wouldn't get quite hot enough. It did sort of start melting the rod but would get it running or even past the "small bogey" stage of melting, hence my keeping my eyes peeled for something affordable from the PoV of mixed gas. The pure O2 with the fuel would seem to do the trick.

Seen a couple of different answers, but I haven't got a link AtM - the eBay link posted (somewhere) for the JM silver rods and easyflo flux looks good as it seems to suggest it should get flowing between mixed metals ok, with the right temps......

Of course, YMMV....... but please post how you get on.....
