Re: [TCML] Need coil winding advice

Greetings... (sorry if duplicate)
I am designing my first TC and need to build a coil winder. My first
secondary coil will be:
Length: 18 inches
Wire: 26 AWG
This is something you can easily wind by hand.
1) lay some strips of double stick scotch tape the length of your form.
That way, the wire tends to stay down.
2) you need some little pieces of masking tape stuck to the table or
surface near you (or on one of those little wrist holders that package
wrappers used). When you get to every 100 turns or so, you can stick it
down, and put the darn thing down.
3) put the spool of wire on the floor or table, with the axis vertical.
Put a plastic funnel, the large diameter of which is somewhat bigger
than the spool's OD, over the top of the spool and feed the wire up
through it. That will tend to keep the wire from just falling off the
spool, or you having to put the spool on an axle and then worry about it
free spinning, etc.
have at it. You can trade hands (hold form in left, wind with right,
then swap) etc.
In an hour or so, you'll be done.
Now.. if you are going to wind more of them, or the form is heavy enough
that it won't just sit in your lap, a winding jig is nice to have.
Or, if you want to do the rotisserie scheme while coating it with paint
or lacquer, you need a jig.
Check out the barbecue rotisseries.. cheap, they have the v blocks and
the shaft, and they run at a convenient speed.
