Very good conversation guys!
Well once I get hs thing fixed up we can play around with different arrangements such as coil offsets and multi triggers, branch outputs. The way I built this thing it is very modular and lends well to experimentation. First I have to get it running Lol. Darn thing ran great for a few weeks. I did shoot one vid but it was a private one so I was cursing and quite informal with the presentation.
Originally I wanted thematchd transistors just to say this is it, it's as perfect as I can get it but now I am mucking things up. I will say that I do understand fairly well all of the points being made. The coil slots on this are 1/2 inch which was to allow a little wiggle to get coils alighned when you take into account the quarter inch bolts it leaves a little in case the coil mounts were not perfectly the same etc.. So I have tried to gt those all lined up nice. The resistors are one percent wire wound 25 Ohm on the base, another one off the light bulb and of course the light bulb itself. The trigger buss is a full circle coming off the pot so that there is no close end far end delay if it would even have factored in that is. The busses are not daisychained from board to board they are solid and each board connects to the common buss. Anyway the point is that I did think about the even distribution, trimmed coils to all match exactly the same resistance. Of course no mater what you do there will be factors such as the magnet or transistors internal resistance. We do what we can right ;-)
This is my biggest machine to date. I had a lot of fun with two coilers, I had a few of those but this 4 coiler is quite different,, can only imagine when it's an 8 coller.. I can get away with such low resistance because remember it's a super pole and the pole switches very narrow. basically I have 50 Ohm in actual resistors, the bulbs, and a pot which I only use maybe under 100 Ohm of.
Once again thanks for all the participation in this thread guys!
