I looked and looked and could not find anybody willing to wind my
ignition coils. Probably most are made in china or with automation.

A coil winder that would do what I need done is several thousand
dollars.

I had to invent my own.

Can anybody tell me what it has in common with the Wright brothers
flyer ? :)

How about using a fishing reel with the mechanism to wind the line
back and forth. Just modify it to be able to remove the end opposite
the crank. Could drive it with a drill and use a micro switch to
turn it off when the required diameter (number of turns) is reached.

I have never gone fishing :) They are costly are they not?


The bearing plates are done with the bearings pressed in.

Paul, That crossed belt would wear out in a flash would it not ? the
fishing reel idea is a stoke of genius apart from having to
dismantle it to change reels, the front loader type of reel would be
ideal though. Chris.


The RPM is rather low and they are cheap O-rings 10 to a McMaster
pack.

Or, you could replace it with two inter-meshed spur gears. The
output will still go in the same directions.

Mark LaPierre


I don't want it to go in the same direction :) That is a lot more
work and cost anyway.

Paul Lamar


To clarify, it will go in the same direction as the crossed belt, most
likely at a very similar speed.

The transverse  speed of the wire feeder must be finely adjustable to
accommodate wire of different sizes.
That rules out gears and chains. It is only necessary to machine
different diameter small pulleys.

Paul Lamar

What gauge of copper wire are you winding?
C. Smith


30 gage and above

Craig, do you know the required dwell time for coils on plug?
