Bottom draining thermopot.

[geetee]

I have launched an order for an 80 litre thermopot for Mashtun from Germany, they were out of stock but will arrive and be despatched 24th July and I want to be ready to convert immediately.
I have read Vossy's legendary thermopot conversion post but would like a bottom draining pot without the fiddly screws.

I remember seeing a Yacht deck fitting that some have used but having searched boat suppliers got confused by the variety and thread sizes available and declined to order. I assume the fitting would connect to a 90 degree elbow and thus to a tap.

Does anyone have a link to a fitting that would fit thermopot for bottom draining and for info are they threaded the full length or would they need washers or packing or does this not matter?

is what i used chopping off most of the threaded barrel so it could screw into ground down SS elbow within the bottom void.

Fil - how do you chop off the end of the fitting, whilst keeping the thread intact so you can screw it into the elbow? Sorry it this is a silly question, but my metal working skills are quite limited :)

angle grinder with a ss cutting disk, then wear it down as with the elbow on a belt sander, a file will help open up the 1st thread and then work the 2 peices together.

to open up and work the inner thread of a SS elbow thats been ground down use a tapered bsp thread as its thinner at the end and easier to catch, i made a tool from a nipple and T using the T as a handle to work open and lubricate the thread.

it can take a good 5-10 mins? screwing in and unscrewing to ease the threads after chopping/grinding down, a bit of oil or wd40 helps
wash out any grains.. remember to soak/clean off any oils :)

with the right tools its an easy job, without em ??? SS is bloody hard!
