Dear Mr. White,
I have some used tin to put on top of a shed. I want to be able to cut it straight and keep it in line
with the building. Can you suggest a tool to cut across tin and to keep it aligned with the
building without doing damage to the tin itself.
The tin has small grooves in order for it to be joined together on each side of the tin. I want to be able to
cut through those grooves without mashing the ends of the grooves together. If the grooves are
mashed together the tin won't join properly.
Please respond as soon as possible. I would like to start in the morning.
Thank you for any cooperation.
The Tin Man Respondeth:
This is tricky, because the sheet is thin, and folded back onto itself.
I would use a good saber saw which offers variable speeds, and an assortment of fine (32T) steel cutting
blades. The finest teeth are required for very thin (<.032") sheet. Oil the metal. Test for
appropriate speed, which is between where the saw bucks (slow) and where you smoke the teeth (fast).
If possible, insert a metal or wood shim in the fold, so the saw's distortion is minimized. If not, get a
thin screwdriver to open up the fold after the saw has rubbled it.
