Bending a bow pulpit to fit

I am trying to fix up my little potter for cheap. I got a bow pulpit for the boat, but it came off something different and is not an exact fit. The support struts that are aft are a little too narrow. I could mount it as is and it would work, but I would like to bend them out a little bit.

Can the material that a rail pulpit is made of be safely bent? If so how do I do this?

The pulpit is tubing, not pipe, so it either 1" OD or 7/8" OD. It can be bent, but is hard to bend if what you are trying to do is actually straightening an existing bend. For the 7/8" tubing a 3/4" EMT bender will probably work the best. For the 1" a 3/4" Ridgid pipe bender would work better. The tough part is not kinking it. The benders used to make these rails have shoe that fits the tube exactly, and a half round follower block that fits the tube exactly. This keeps the tube from collapsing. However they don't straighten tubes well at all.

Thanks for the elucidation Gary between pipe and tubing, seems important to know before i bend and tweak the rail. I was trying to figure out how to get at a pipe bender as i am out of town M-F. The aft stantions just need to be spread out about 3 inches or so wider per side. I think just a subtle tweak at a few places along the rails running aft may get it to line up a little better with the bow.

I am not sure if they have a bender in Home Depot or not but figure I could sneak a few tweaks on the pulpit in HD this weekend, if not I'll try the cars and chains idea. Not really.

This is how I did it

Just following up on my thread, so it may be used as an archive in a search.

I was able to find a conduit bender from Lowes for $38. First attempt was with me holding the pulpit while my wife cranked on the bender. It felt like it moved but no such luck.

The hard part is I needed to isolate the area next to where I wanted to make the bend from moving. The plan was to lash it to an immovable object the crank. Here is the setup. I made bend in two places along the area and then put it against the boat and it was a bit too wide. So I removed some of the bend and flipped the pulpit around and bent the other side. Here is a photo of the setup and the results.

PS the 3/4" conduit bender worked on 7/8" tubing pulpit and I guess it would work with 1" as well

i have tried to get mine to straighten to where i need it and it wont move. i have to make a new one in the spring, or use hydrolics to try to bend it
Hey Scottyt,
Have you tried the conduit bender yet? I've got one for sale, cheap. I tried to bend it with out tying it down and got nowhere. After I secured the area next to where I wanted the bend to occur, so it would not move, I was able to apply bends pretty precisely to the location I wanted to. My first bend was too much and I had to remove some of it. I then put a few bends on each side I wanted to bow out so it came out as a smooth curve along the section instead of a single bend.

Granted mine is pretty basic and the amount of movement I had to make was simple, but you might get something more square then let the bolts do the rest.
