I have a double block that mounts directly on a deck with four screws that go through a flange on either side of the blocks. I'm putting this double block on my deck in a very tight place next to my mast. It would look a lot neater and have a fairer lead if I tucked it into a small molded crevice right against the mast, but to do that, I would have to bend at least one of the flanges 180 degrees so that it faced under the block. The flange is only 3/8" side (just enough for the 1/4" hole) and about 2" long. This is the "shelf" that would have to be bent 180 degrees under the sheaves. Can you bend stainless without it breaking or becoming substantially weaker? The link is similar to the block I'm installing. Thanks in advance

I wouldn't
Things to consider. When bending the flange it is very easy to distort the assembly, and jam one or both sheeves. Even if it does not bind up on the bench, mounting the block can cause loads that bind the sheeves unless the flanges fit the deck perfectly. If you do manage to get one side bent 180 deg, how will it effect access to the mounting hardware? I think the chances of success are low and the probability of ruining the hardware high.

Bending SS
Yes, you can bend stainless steel. However, you need to use a bending brake with a shoe that controls the bending radius. In your case, you will have to bend it by the armstrong hammer method. It is very easy to get too small a radius and crack the metal.

From the picture and your description I don't
see it happening Rich. I think it would break, it's already been bent 90 one way and I think you want to bend it 180 the other way. If by some chance it doesn't break, it going to be very weak on that bend.

possibly
remove the pin and rebend at the 'strap' that crosses in front of the sheaves, it would place mounting hardware under it, and allow closer mounting, Depends of the axle material and construction, though a suitable axle could be fabbed with ease. The only way to bend it without damage would be to heat it, which looks like it would damage the sheaves. Only other option I see is to cut it just above the bend and mount an angle there to get the feet in position, plenty of room on the sides for rivets or smooth screws. ken

Pop the pin
If you pop the sheve pin and then put the left one on the right and the right one on the left you don't have to bend them. Of course you are going to have a dickens of a time getting a screwdriver on it so install the brackets first and then install the pin and sheve.

A new leg? Does stainless weld well?
All good posts - thanks guys. Access to the hardware shouldn't be a problem because I figured I could push the bolt up from below and just use a nut and small washer on it. Unless there are more ideas, I might try cutting off one leg and welding or screwing on a new leg bent inward. Rich L
