canopy bows

Postby Onex93 » Mon Apr 03, 2017 2:57 pm

Hello,

I've been struggling to get the canopy bows to adhere to the shape of my plywood templates. Does anyone have any guidance/ alternatives?

Thank you

I finally gave it up and just bought a tubing bender.

What did you buy? There seem to be a lot of options from cheap to expensive for tubing benders?

I actually bought a conduit bender at the local hardware/electrical supply store. I have two tubing benders, neither of which are large enough to accomodate the canopy bows.

If the Onex bows are similar to the Sonex that is big radius bends you shouldn't need a bender. All I did was screw a couple of wooden blocks onto a flat table a few inches apart and did like this bloke does bending heavy square tube.

As with all metal, will need to slightly overbend to allow for springback.

Did same as Steve, works fine. If concerned about kinking the tube, screw a 7/16" bolt in one end, fill FULL with sand, screw second bolt in other end. Be sure to allow about 6" tangent each end to cut off after bending. Assuming original A model, if not already doing so, push windscreen bow up as far as possible with supplied Lexan material. Makes for a bit more headroom and cleaner line.
