Ive been wanting to make a sissy bar for the bike. I tried my damnedest yesterday with just propane to heat some bar, but it was just brute strength that got a bit of a bend in my 16mm steel bar.
Decided to bite the bullet and get an oxy-acetylene kit sorted today.
This is the starting point. Not great as I should really be heating a flat bar - but I got impatient yesterday and tried to bend it cold. Not a good idea as it doesnt bend just where you want it to - it bends all along the bar to a lesser extent towards your hands...
Once heated I bent it round an old socket in the vice. as much at the top bent how I wanted it to, you can now see the results of my impatience, in that the bar was not straight down its length giving an arch rather than a point....
so..... heat up the area - all the area that was curved was heated (the picture may be a bit deceiving)
got my mix a bit high on acetylene to start hence the soot - but I think you can see the difference left and right now....
then sorted the other side...
next up - the kick back at the top - just put it in the vice and heated up...
first try on the bike....
oh how I wanted it this high! it was taller than me (6'5) an would have looked mental!
so much so I couldn't get it quite in shot....
as you can see it was far too skinny to get past the wheel properly - now the fun began!
bent the legs out to a rough 45 degree bend (by eye - so its slightly out and the top isn't totally perfect - but I don't mind for effort #1)
then using a fire brick, some wood and plenty of heat bend the legs back on themselves...
trial fit on the bike, and its spot on!
I then trimmed 3 inches off the bottom (the legs weren't equal anyway - but sorted that out) and made some tabs which I welded on the bottom.
havent fixed in place yet, the angle will need to be sorted when its on its wheels rather than arse up in the air....
happy boy!
Yeah mate, I should make the trip down and say hello when the rain stops.
ReplyDeleteAbout November then?
sounds about right - I'm thinking of installing a gazebo from the ape hangers to the sissy bar....
