hi thanks to every one who has given this some thought and posted ideas
to answer another question the antar is owned by kevin (antarkev) and i am slick0007 or peter who is trying to help sort the problem
we have had a small break throu we had it running for two hours by blowing compressed air through the mag cooling pipes we are puzzled by the original set up as we cant see how it would curculate air through the mags to cool them
please keep all your ideas coming and we will keep you informed of our progress
thanks again kevin and peter
