Any chance of mother's daugther elbow for 3/8" ID tubing ?? I might order 2 if you come out with some of them

[0xdeadbeef]

Thanks guys,
Anyhow, I probably shouldn't plug up the water cooling forum with this, and since there was support for making more, I've created an official FS thread in the FS forum.

Boo to that, I would definitely be interested in a couple of these elbows. I would REALLY be interested in some 45 degree ones if you could? I have some rough ones I was tinkering with of my own but would love to get my hands on a more polished looking product I woudl take 4 90's and 2 45's if you would be amenable PM me with paypal details if you want and I could shoot you some cash for them.

I have over 300, and I still can't see it...

It's fully on the bottom but if you still cannot see it, ask a admin.

LOL, actually I've had one many moons ago. I founded katanaplanet.com for my streetbike enthusiam years. I ended up having over 1000 members on my own forums. Eventually I gave it to one of my long time members because I upgraded the streetbike and no longer rode that one...hehe. Yes, I'm a bike nut too, street and dirt bikes..

Sure, I have some brass bar on the way too, but you'll gain some pressure drop with the smaller barbs and I havn't tested it to know how much. Maybe I should get copper bar?

No need to have access there, just PM me if you want some and I'll put you down.

Anyhow, continuing with the production and while I was at it, I made the obligatory.

MOTHER OF ALL TEE FITTINGS...

They take a bit more work, so I'm thinking $10/ea for the Tee...?

Who needs a reservoir, when you can have the mother of all Tees...I'm getting much better at sweating copper pipes..it's all about preparation and just the right heat...

Here's one I TIG welded from 304 S.S. sanitary tubing for my CM690 build



Would be nice if it had a radius but it does its job.

[Nanometer]

If you use 1/2 inch tubes, you can fit those tubes over the 1/2 inch copper elbows and t-lines. It's what I use.

Nice work. I used to do alot of TIG welding back in my machine shop days, going to have to buy a small one for the garage at some point. Once you've used TIG and a good variable foot pedal, nothing compares in the control you have.

The nice thing about sweating of the copper though is it almost eliminates any risk of a leak. If you do it just right, you can feed in a good section of solder that completely dissapears and bonds with the fluxed and prepared surfaces. Welding on the other hand is a bit trickier regarding water proofing.

'Twas a bit sloppy but I just slapped it together because I was in a hurry. Typically my welds look like they were done by a machine. I can say however, although I have been welding for almost ten years now I still stink thoroughly at soldering and brazing.

Here's a pic of one of the thin film deposition systems I build at my day job. We get the tanks built by a tank fabricator and then I weld all of the cooling channels on and we get it electropolished. There are also channels on the inside that you can't see, but they must stay leak free in a 10^-7 torr vacuum(basically outer space). Can you guess how fun it is to leak test them?

[Martinm210]

Oh..nice.

I havn't picked up a wire feed or stick or TIG for over 10 years now, and welding was only for coolant tanks or other liquids, never something like that. Most of my TIG welding was for saw blades and special cutters, but I just really liked the control and clean welding of the TIG, the rest of the time was most shop project fabrications using a wire feed, I did alot of that too.

I also did most of one summer inspecting plastic welds on a sewage treatment pond liner...that was no fun. Now I'm stuck at the desk, I guess that's why I like fabricating in my garage so much. There's just something satisfying about making cool stuff with your hands..

"Walking the Cup" is definitely an art.

[qdemn7]

Martin, something you might also think about is a high-flow G 1/4" barb. Probably could sell quite a few of those.

[Martinm210]

Thanks!
I've had a few requests for the sides of the elbow to be G1/4 threaded also, which I'm going to look into here shortly as I just got my brass bar order. Also 45 degree elbows can be done easily the same. After I get the current que cleared out, I'll start looking at some different custom fittings. Not sure manually turning barbs would be very cost effective, but I'll look into it. The nice thing is...making a few manually machined prototypes is no big deal, just takes a little time....

FYI
I've been busily cranking these out and working down the list of folks that expressed interest. I think I'm almost half way through the list now. Thanks for your patience!

Going to have to hire the local paper boy and make a machinist/fabricator out of him..

[nikhsub1]

Well i got mine! Thanks Martin! They are impressive in person, VERY nicely made!

[Martinm210]

Great, thanks!

Making my way through the list, also doing some prototypes of different options like this one sided G 1/4, but still trying to figure out a way to streamline production..



I'm also hearing interest in a 3/8" tubing compatible version. To make it cost effective I might look into buying some premade 1/2" hosebarb sweat fitting and see if there is some minor work I can do like boring them out to 10mm ID to make them less restrictive. Obviously the 5/8" copper originals will have the lowest pressure drop though.

Regadless, I am investing in some new pressure drop equipment so I can make myself an indoor pressure drop testing setup, then I can see how much impact the smaller fitting have on the larger elbow. I suspect as long as there are nicely tapered transitions, you'll still see good performance from the elbow with smaller fittings.

[madmaxx]

very nice work Martinm210

nice to see that there is still room for improvement and fresh ideas in the L/C community

[Kayin]

As I use no bigger than 3/8", I'm pretty interested in the smaller ones, but I may make my own out of polycarb castings...

[Nate P.]

Nicely done, Martin!

[freeloader]

Some damn fine craftsmanship!

[Martinm210]

Thanks!

FYI, For final cleaning I've been using hot soapy water and a tubing brush to clean the insides really well, then to provide some protection on the exterior polished finish, a heavy waxing that should minimize oxidation. I had thought about clear coating, but it would probably fill in some of the barb effectivness.

I think I also found a source of materials for the 3/8" tubing capatible version that should work pretty well. They will be made for 1/2" tubing without any streatching, or 3/8" tubing with some work. Planning to bore out the barbs to 10mm, so they will flow just as well as any of the commercial G1/4 high flow types, but instead be finished in a nice polished brass. It'll be about a week or so before I have my materials for the smaller barbs.

[Xilikon]

I cannot wait to see them
