a couple weeks? in the meantime i will make a whole lot of mountings :) Gotta get a reply from dolphin on how to use their software with a slitting saw...

sick reed!
Glad to see things have picked up again!
I don't see any ads on your site though, or else i would click a few for ya...
Nice work :up:
I was just wondering, if a evap has more mass/bigger would it hold load better?
Thanks
i feel very pleased for you reed well done
Can you believe i actually qualified in NC programming (the for runner of the cnc) 25 years ago with punch tape these machines have come a long way
Come on Barrie,
it's still XYand Z -but then add A B and C and you got some bits going on!
Your engineering skills will put the machinest skills to the test.LOL
Eric,
cheers guys :D
baz- haha thats cool!
alright heres my new little guy :)
whats next:
-I have the top to the evap drawn up in cad, gotta run it through cam and make a top. it has a nifty little trick to it too.
-Program the slitting saw, by hand, to run around the side for a snap ring.
-make a jig for hold downs so i make some hold downs with a good finish
-send it off to have it tested, tester going to throw it on a system and if it works well, im going to make a bunch of them. if it works just mediocre, i will change a couple things. I highly doubt it will be a poor performer, but only time will tell.

bead blasted... needs to be deburred :( i really need a new deburring tool, broke my old cheap one.
i should be able to get the first evap finished by sunday...
cheers
Wow... great design. Hope it does what you intended it to do. :up:
Please report back your findings, one of my coming singlestages is having a similar evap design.
Looking good!!
way to go teyber can't wait to get some stuff from u but i do have some evaps to go through first but i will need a mounting for the monstor evap that u are selling me
Cheers guys! I made a short 50 or second video, I will try to post it asap also
lookin good man, your work impresses me very much
cheers buddy :D
Here is a way late video.

Looks good!!!
Cant wait to try one of those bad boys out!!
I fear this; the evaporator design is very short. If anything I've seen in testing, the longer pathway is so much more beneficial to have. Sure you've got good surface area, and you seem to be banking on some kind of turbulence that I don't think really will occur, but it's just not that long. That's like using a 8" piece of 3/8" tubing as your evaporator.
thanks for your advice but there have been several high performing evaporators that are much shorter in length then this one
Throw some damn refrigerant through it then!
how does this new evap compare to your old ones in performance terms?Quote:

thanks:)

almost there... for the practice ones i just use alu, of course they will be copper.
Sorry didnt see the earlier question...not enough resistance before suction...Quote:

Hey Reed one thing you might want to try instead of having to program by hand for the slitting saw. Just make a end mill at whatever the size of the slitting saw 3 inches 5 inches whatever you need. Then in the software just set the depth and the path you need will require a little work but better than doing it by hand.
well guys i have tested a chilly1 next to the coldwave and i found that the delta-t was much greater on the chilly1 but both gave good evap temps both around -30c at a full250watt load
