small ring roller?

[johnakay]

thinking of making one of these for 10 mm bright bar.
its for the tail end of a Suzuki t500 rack(see picture.
so not a full circle just partial.
the only thing I'm not sure about is the bearings?
may not be able to take the load of bright bar pressure.?
do you guys think this will work ok?

Bearings take a lot more load than most folk ever think they will , Look at the thrust bearing on a q max punch as an example ,,

Neat and compact and looks easy to make - I like it.

Should be fine. Take it steady rolling in small pressure increments and you can roll some decent sized stuff and 10mm takes no bending at all.

Might struggle to track properly without proper grooves, though.

I made one out of bits and pieces I had lying around, the bearings I collected when fitting various timing belt kits .Total cost was zilch

And wear safety glasses when testing, if the bearings do let go, they do so at high velocity.
Don't ask me how I know

Made one years ago that utilised my bench vice, mounted using the jaw mounting bolts. Worked a treat. Worth considering.

well that didn't turn out as well as I thought struggles to slightly bend 8mm bright bar.
will 6mm but thats it.

Should've put a pik in this post, it was a bit vague ;o) This is what I'm talking about. It easily copes with 12mm round and I've made hoops out of 6mm flat bar with it. The 'grunt' of a nice big vice helps.

went back in the garage after seeing the video.
I realise where I went wrong.
what I did was drilled 12mm hole through the two front plates and tapped out the back plate WRONG!
the two plates at the back is straight through and the front plate threaded.
I notice also that the round bar was not turning so I was fighting against that as well as the bar that I wanted to curve
so after the mod,walla it worked a treat.
bends the 8mm rod so easy. so very pleased.
all I need to get now is a bigger round rod 40mm so I can put a better handle on. here's a couple of pics front

and back..

While thats a handy tool to have, i'd have just bent the steel round a gas bottle for the rack
