Re: [TCML] Secondary Wire splice technique, gear reducer 4 sale
I can't help you on most of your questions, I don't have the experience or knowledge.
However, I did recently buy 25.3 lbs of 18 AWG high temp magnet wire for 240 dollars shipped, from Fay Electric.
Also, the average electric drill isn't meant to run for too long.... I burnt one out already. So as of now I wind/spin by gloved hand.
Took a long time to wind the 13.3"x60" coil...

Subject: [TCML] Secondary Wire splice technique, gear reducer 4 sale
Hello Friends and Fellow Coilers,
(1) I am preparing to wind nearly 22 pounds of #18 >200 degree wire. This is
available to me on 11 lb spools at near $100/ spool. Is this a good price?
Can I get 22lb joined or bigger spool? I emailed Essex but they never
emailed me back:-( I know how to silver solder a tapered splice which
shouldn't be too hard with this size wire. My question is what to coat the
splice with of very high dielectric coating properties? I want to keep the
windings adjacent for ascetics.
(2) I do plan on my usual few coats of polyurethane and may try my luck with
pour on 2 part epoxy (never tried before by me)...I can deal with drools!
This is a ~7500VA coil. I guess I would want a slow cure product and of
course constant turning. I would appreciate some experienced responses of
conquered or failure mode hard knocks on these issues. What's a good pour on
product and application techniques? This is a new .125" thick 12.25" PVC
former a big 5:1 ratio. It is getting a 56-60 x 12" top hat to shield the
coil. I can give more design specifics if anyone is interested.
I am building a mucho winder with a worm reduction gear box and an AC freq
controller .5hz- 360hz near constant torque. It makes up to 3 hp 3 phase
from single phase 240v, the next wind is a 22-24" sono tube. I'm using 2"
thick wall hard conduit as the axle. The weather is hot and very dry this
time of year in Ojai, Ca. - Good time to coat and wind!
Thanks Much,
Jim Mora
For Sale:
I have a smaller gear reducer .5" in (1/2" VS drill would be a great driver)
output 5/8" 13:1 ratio I believe it is 175 in-pounds of torque. It looks as
new and turns freely with zero end play. I decided to go mongo (heavy duty)
for the sono tube on the same rig. How does $30 sound? Just use a wide type
fan belt on a 2"x 5/8" shaft alternator pulley and wrap the flat belt around
the end of the coil form. A used timing belt would work well too.
