Also up next is the inlet and outlet cooling water ports, I’ve heard many have gotten excited and missed this step. Cheers for now.

Very nice shotgun condenser I used the same wind chimes for the one I have

I didn't see a 2X1/2 inch reducer in your inventory. What do you have planned for the end of that shotty?

StillerBoy wrote: ↑Thu Apr 22, 2021 4:46 pm Mashable.. a word of caution on soldering the ss ferrule you have on hand.. those ferrules will be difficult to solder cause of their length.. they look as if they are the long one, if it were me doing it I would shorten then down by half at least, as you don't need more that 1/4" been soldered to the copper.. and much easier to solder without affecting the other area close by..

Matching the pieces is the easy part, soldering them in place will be the fun.. for soldering ss to copper, especially the ferrules, using a low flame/heat and take the time to warm it up to soldering temp..

A tip on holding a ferrule in place if the fit is on the lose side.. cut some fine copper wire and make some V pin, place 3 pin in position and then lightly press the ferrule in place..

A couple of tips for your soldering journey. I recently finished my modular build and I learned a couple of things the hard way.
Patience! I used propane for my entire build. It takes a bit to heat things up.
I found after a couple of tries that the Bernzomatic TS8000 is a really good torch for this job.
Make sure all your pipe and ferrule cuts are square and make sure they are square before and during your soldering.
Make sure everything is super clean. Sand everything and wipe down really good with acetone before applying your flux.
When soldering on your ferrules take your time, be patient. Heat everything up as evenly as you can but don't get it too hot. I did it by heating,, removing the flame from the joint then touching the solder to the joint. Repeat frequently until the solder melts and is sucked into the joint. At that point is is a simple thing to work your way around the joint using the same method all the way around. It is important not to have the flame and the solder on the joint at the same time.
Clean your fresh solder job immediately, as soon as it cools. I used a hot soapy brush followed by an acetone wipe. That liquid acid flux is a bitch to clean out if it sits for any time. You will be glad you did this when it's time to do your cleaning runs.
Follow Twisted Bricks advice on how to solder your shotgun. I did and it went very smoothly, no leaks, first time.

Appreciate the feedback, all very sound advice that I will employ. I have held silver brazing tickets in the past, along with several different pressure tickets for multiple weld processes and positions, hopefully this will serve me well on this journey. Ideally I’d tig (even copper to SS)weld everything, however I’m not in the shop and do not have the capability at home, so silver solder it is. It’s like baking cookies, follow the steps (recipe) the same every time, and you can generate consistent results. Cleanliness is godliness, good fit up, take your time, wet rags to manage heat, and slow consistent heat till melting point, then let physics do its work! Clean, clean, clean.

Deplorable wrote: ↑Tue Apr 27, 2021 1:08 pm Looks good. Nice solder joints, but you should have aligned the water ports between two of the vapor tubes. It looks like you have them aligned over the top of one of them.

How I did mine was, I located them an inch back from the end plate, then clocked the first baffle with the opening opposite the water port. Staggering the baffles 180 degrees through the stack.
