Hi Hy
      If you are running your primary tank without a secondary then you are 
generating ~ 1kW of heat in the cap-gap-coil loop. No wonder it's getting 
hot! If you are really in love with the bolt-type gap then use brass or 
aluminum rather than steel. You can make "radiators" for your bolts by 
stacking fender washers or copper disks alternately with regular washers on 
the back end of the bolt as cooling fins:
