The rods you can get at DRP performance (off road) supplies. Anodized aluminum
They do sell an 1.125” diameter rod BUT it has same 9 peak profile as the 1/2” shown here and would be spread out even more and why I didn’t use the bigger version.

You will notice that the peaks and valleys do not follow a perfect 1 to 1 ratio as you would in say , straight cut gears in a racing transmission for instance, but anything in this length is difficult to find and while not what I would want ultimately, it is what it is..

A decorative light pole or floor mat pressed together�� might work hehe

Hmm i was hunting for crimp rods to extruded belt gear/pinion stock rod/bar woul;d work to, but i found the price still rather hefty.

when i think of it Coolblock in bar/rod should fit the bill to. often they are extruded , just like my crimper from the hobby shop. gone do some searching again, else i just machine some out of mdf or something im afraid and stack them

extruded heatsink round - Google Search


what also could work, is buy serveral of those hobby paper crimp machines. (for me the best plan i gues) put them on a rodd , line them up and bolt them together they come often in 8inch long. so 4 of those lined up and some bearings should make a machine. in the worst cant you should have a idler wheel (riding the corugration wheel)in the middle keeping the rods from bending to much.

From “L” bracket to L it is 30” long with a 20” cutout area
I did place some cutoff inner tube bands for a little more pressure on the rods
With a little spray lube to rotate easier

Less than 50$

I did think about a spring pressure upper rod with slidable greased plates on the outside L brackets
and might go this route since I would like to try the bigger diameter rods on another set
of wave cut foils

Ha nice, i did not read you already addressed the bending ! great minds think alike .......i wish i could find that size of rod , although the corrugation is a rather funny one, they dont interleave like all that hard. it is far more gently to the foil i gues, did you corugate a test piece somewhere here ?

Post #118 is a comparison to a stock foil vs my version and 119 is the
complete panel
The peak of the corrugation does touch the valley depth but it doesn’t follow it perfectly
because the valley width is wider than the peaks profile
Not perfect , but close enough for a bass panel

Drp performance has all widths and OD diameters and made of 6061-T6 anodized aluminum

David

Another way to corrugate would be a ribbed floor mat.

One could take a plywood strip 4 wide by 20. 2 pcs and cut 2 sections of the mat and spray glue
To each side of each block the rubber mat and these would be used to compress across
each foil panel.
You just keep going line by line. It might be an issue on each start next to a finished line but worth a try on a test piece.

You might have to provide a depth stop on 1 board and the Kapton back soaped down as the width will draw the foil in due to corrugation shrinkage

You could get fairly accurate lines and not damage either side of the lamination.

I have not tried this, but seems doable and cheap
