[AJD] Looking downstream - Heat

[Mitchell Daly]

Mike,

Check out Harbor Freight.  They have a small bottle rig complete in the catalogue and also in the stores. Also, When you get a bolt that might be broken off with a stub left to grab, heat ONLY the bolt to cherry red and then press a candle down onto it. Let it cool and with a pair of pliers, you can walk it right out.  The wax flows down around the threads and the heating and cooling help break it loose.

  Bus Driver, Duane, Steve & Karl -

  Thanks for your recommendations.  My propane torch head also accepts MAPP gas 
  so I'll pick up a couple bottles to have some heat handy until I get a more 
  substantial outfit. The List responses make it clear to me that an oxy-acetylene rig is 
  the direction I need to be headed.  Steve's suggestion to look at the small portable 
  oxy-acetylene rigs really got my attention.  It looks like one of that ilk would suit my 
  needs just fine now and if I grow to need a larger outfit in the shop I will still have a 
  portable capability.  Now I can shop with confidence knowing I'm getting the right 
  type of tool. Thanks to all of you.
