This is a bit of a continuation of the radius cutter to make rollers, to make a ring roller, to make a floor lamp.
I've now got as far as making the ring roller and curving a bit of tubing, so here are a couple of pics.
This pic shows the three finished internal radiused rollers for 21.3 diameter, 3mm thick tube. They have a 1" hole down the middle.
The rollers mounted on a 10mm plate with 1" round bar welded to the plate for them to run on.
The adjuster for the middle roller. I started milling all the bits but it turned into a bit of a pain so just cut it all with a plasma cutter and bolted it together using 20mm thread bar for the adjuster.
There is also some 2" angle welded to the bottom to strengthen the points where the 1" round is welded to the top. It also spaces the whole lot off the table.
Another view with the rough slot for the adjuster to run along, with the adjusting nut at the end. It's clamped to the bench ready to try out.
A rough handle bolted to the adjuster roller to give a bit of drive. It's only stuck on roughly so i can chop it off once the job is done.
The first go with it. the yellow marks are supposed to be on the top. It was awkward to hold the tube and turn the handle, at it's furthest point away,at the same time.
This is the finished curve. The 1" angle welded on the end was to try to keep the curve in the horizontal plane. You can see from the angle that it didn't realy work. It has a bit of a spiral in it which i should be able to get out.
I think the weight of the tube was causing it to drop down when going through the rollers unsupported and causing the spiral. I can see why they are used in the vertical position now.
I don't know if it was worth all the grief just to make one floor lamp.
The rollers i will keep and use if i make a tidier ring roller.
