Re: Primary coil

If you want to get a nicer looking primary, you might want to try using eight spokes of support instead of four.

BTW, I have used wood for primary support on my first coil using a 12KV 30ma NST. The wood was varnished before mounting the copper and it never failed. Of course I decommissioned it to work on my 2nd and larger coil. For that, I used HDPE for the supports. It is softer than acrylic and doesnt have the tendacy to crack.

Hi, thanks for the replies. Matt D, I will only be using a 9kv 30ma NST for the coil. Should I still add the HDPE plastic or will it be ok? I think the supports are at a 35 degree horizontal angle, but I am not sure of the difference between the two. I cut the bottom of the supports to a 35 degree using an angle cutting table saw.



Ed, I had just assumed the epoxy was flammable. The package confims that it is not flammable. I do care about how good the primary looks, and tried my best to make it look nice and even. Mounting another piece of wood or some plastic on top is what I will probably do.
