Re: Here's the condensor pics ....ATTN : Derek
>>If you did not describe your winding method, perhaps you could doso.
Take a 20 foot segment of tubing and completly fill with salt. This
requires using a small funnel and tapping the tubing as you fill. I
worked from each end and placed tape over the end not being filled
at the moment.
I left a two foot long segment of the tubing uncoiled and taped it
parallel to the broom stick. This gave me leverage to begin my
coils and a segment with plenty of length for plumbing up the water
later. The two foot segment will be the "top" of the condensor, and
I wound "down" the broomstick....away from the 2 foot long straight
Using the formula for a circle perimeter ( 3.14 times the centerline
diamter of the coil ) I was able to estimate the length of the
tubing that I would use going "down" the broomstick and this being
where I would begin forming the coils back "up" the broomstick.
Just remember the centerline diamter of the second row of coils will
be greater than the inner row of coils. My condensor doesn't come
all the way back to the beginning point, but I chose to do that so I
could pack a scrubber around the outside of the coils and one down
the center of the coil to condense any vapor that may try to pass.
With the two foot of tubing taped to the broom stick, carefully
begin twisting the tubing around the broom stick going "down". I
heated the tubing with a propane torch to soften and allow the coils
to be made a little easier.
I only heated about a foot of the tubing at a time. As soon as that
one foot is heated (about a 30 to 45 seconds) I began to make the
coils. Only forming coils with the length that was heated.
I used a leather welders glove and would press or force the tubing
around the broom stick holding the tubing near the broomstick. It
gets a little warm even with a glove but not too hot to handle.
After one or two coils are made I would heat up the next one foot
segment and form more coils. Continue this till you reach your
return marker that was placed using the formula above.
Repeat back up the coils already made leaving enough length of
straight tubing to plumb up the condensor later. Hint: I left the
salt in the tubing after forming all my coils so I still had the
benefit of that packing in forming any additional bends I needed
after placing my 2" cap on.
Hope this helps!
