Default Sweeps

Just thinking out loud here - what about using a Pullmax nibbler with a jig?

I just spent the money and got a set laser cut. $1000 and done. It sucked to spend the money at the time but i dont regret it one bit.

Default ring roller sweeps

I have made radius (sweeps) gages with a HF ring roller. (Modified of course) I usually use 5/16" square CRS. They are not stiff like the laser cut templates. But there are very few true radius shapes on a car body.

Kerry is correct. You can make a true radius easily. Making it exactly 40" radius is not so easy. A CNC ring roller will do it.

For my work, I prefer the flexibility. If I need to hold a shape I will tack weld to a backbone.
They are so cheap, I don't mind modifying them. Not something I would be inclined to do with a $1000 set.

Make the sweeps however you can. If they are not to exact radius, so what, it is just a reference. Saw them on a bandsaw, jigsaw or whatever. Then sand them with a long sanding block to average out the inaccuracies. Good practice for fairing curves in panels.

Another possibility, shear 1 1/2 strips of 16 gauge steel then shrink one edge to a curve. No shrinker, stretch the other edge. Make a bunch and you have a set for yourself. Don't make a dam what the radiuses are, you just select what suits the panel.

The sweeps don't need to be perfect unless your work is without flaw.

Thanks Steve and Joe. I know you know how the set up works. Hope you are getting lots of use out of it.

Or you could make one of these for around $15!

Adjusts to any curve and does reverses too.The " flexi blade" is made from 4mm PVC strip and the slotted parts are bar stays available from hardware stores.

I don't know about you folks in the first world, but I can buy a lot of more important tooling for $1000.00!

it's understandable not wanting to spend vast amounts of money as it could be spent on other things. looking at this from a different perspective buying a set also works in your favour at tax time as its a tool for work. you would also need to make a few of those type of tools as some panels have 2 or 3 radii in one panel

Neil, with Mikes system you can make several different radius and glue them together to exactly match an existing panel.
