Re: Dummy

Re: Help! I think I may have just ruined my 9 year old's Chanukah
What is the purpose of the nail varnish? The reason I may have to rewrap....I'll have to take it out of the case to make sure, but it looks like there may be several strands wrapped on top of each

?Woohoo!!!! Real detective work going on!!! I've never done this, but if you can separate them so that they cease to short, you could put a drop of epoxy 5-minute glue there, and it would perfectly

Re: Help! I think I may have just ruined my 9 year old's Chanukah
Don`t go to all the hasle of rewinding the coil, carfully separate the turns (usually spaced anyway) and paint on some clear nail varnish or similar and let it dry, then re-insert in the board. Dave
