i am still blowing holes in my 1975 rover sill repair, despite trying to eradicate the problem.
initially i thought i had had not cut back far enough to good metal because the holes were blowing in the old steel. So i chopped right back to thick clean steel.
this still blew, so a mechanic i know pointed out that the patch i had made was considerably thicker than the original sill.
new patch. 0.8mm steel, same as the sill.................... still blowing holes. not only in the old sill but burnt clean through the new repair patch as well
now i am really disheartened.
i have a clarke 135 TE with 4 setting 1/2 min/max. got it on lowest setting of 1 min. using sureshield 5 gas turned full on to try and keep it cool. wire speed was 6. turned it down to 5 at the end of play yesterday, seems marginally better.
good clean earth.
the only ideas i now have is wire speed? would tha blow a hole if too high?
or am i holding the torch too near the metal.
sorry for the long post. am going back in there today with copper to try and use as a heat sink to repair the holes.............
