Forming finger straps.
A finger strap is a reinforcing piece of metal that is used to
reinforce a joint. The impression I have is the strap is heated until it can be formed, then wrapped around both the primary and secondary tubing being joined. For both tubes the strap is formed around them. Is the strap tacked in place, then heated until it's plastic, then hammered/tapped/worked so that it is formed around the pieces, or is it somehow formed off of the tubing that's being reinforced? - Mike |

Orval - OK, I"ll try that on some scrap; but every time the hammer touches the metal, and every place the patch touchs the base metal will tend to cool down the patch. Is there a secret? Small areas at a time? - Mike |

Yep - I was thinking of building a mold by building a like joint, filling it with sand, and heating the strap around that - but I get wrapped around the axel and was looking for an EZ way - MIke |

Vice grip the top of the pipes (needle nose grips here) to keep the pipes from spreading. and wrap the strap around one pipe... Vice grips with soft aluminum footies are "handy" Richard |
