[Public-List] Tiller Head - I'm stuck!

Jeff,

picture is worth a thousands words!!
yep, you may be right, the bronze head is soaking up the heat and not enough Is transferring done the bolt shaft to engage the frozen/ corroded threads.  map gas is certainly a lot hotter than propane.  May be worth a hundred bucks to have a welder come down on the dock with an oxygen/ acetylene torch to do the job.  probably take two minutes if you can apply enuf heat.

If you try Map gas, use a single oriface tip that creates a pin point jet of flame one that focuses the flame into one concentrated point, rather than the  round multi flame head that plumbers use.  a single concentrated  blue flame should put better than 1200 degrees of heat directly into the bolt head, which will solve the problem of difusing heat into the casting.  also will transfer the heat directly down the shaft, rather than disburse around the inside of the tiller  head, as your casting is doing with propane.  the hottest part of the flame is the blue tip, which you can see inside the surrounding outer orange/ yellowish flame. the plumbers tip is designed to only heat copper pipe enuf to melt solder, and burns mostly in the cooler yellow orange heat range.

Last resort, grind the bolt head off and drill out the shank enuf to pull off the casting.  But I will bet you can shag loose the bolt with hotter gas and more concentrated flame.

good luck,  Remember Gord's advice, never let the damn thing know you have any doubt about the outcome!

This is generally the easy part, I had a very difficult time removing the tiller head on #114 a few years back and used WD40/PB Blaster and a torch. That process took a few days to remove the tiller head.
