Slip Roller

how tight?

Ray, have you done the math to see if your setup with the top roller between the bottom 2 will give you enough "displacement" to achieve a 3" radius? :thinking:

Cheers Phil

Yeah, they're a tiny bit off to one side but all is well and I got lucky for two reasons... Both are off the same amount. Both are a little over-sized and when I mill them to correct size, I'll take a little more off on one side... (wheew... dodged a bullet on that one). Fortunately, it doesn't matter anyhow because the height of top shaft is controlled with two independent adjustment bolts... I think Father's Day luck was on my side today...

I didn't even notice the lateral offset until you mentioned it, I was talking about top to bottom :lmao:
 
Instead of a crank you might want to consider a large wheel. We modified the rolls at work with them. They are easier on the back. We had 48" wheels on an old roll because OSHA wouldn't let us upgrade it to power.
 
Here's a handful of videos showing the side plate being made on the CNC machine. All went well but in my haste/carelessness, I grabbed a worn-out finish endmill that was about 4 thou undersized and the final holes came-out correspondingly small -but otherwise very well dimensioned. I'll ream it out in a jiffy and we'll be right back on track.


Here are some videos to watch...

Ray, even your camera is a bit worn-out… the videos are undersized!
:roflmao:
Anyway thanks for sharing, they are nice!

Maybe I need a bigger lens installed on the iPhone... I do have a video camera that makes full-size images but it creates huge files that take a very long time to upload. The iPhone chops them down to manageable size and uploads them very quickly... I dread making videos really -so time consuming...

I guess to keep the iPhone in "landscape mode" would solve the vertical issue ;)

I think you should go back and get them both the same........



The crank handle on mine is 10" long View attachment 78862 View attachment 78863


You can see how much adjustment I have on my outfeed roller. View attachment 78864

And because the rollers are just in sloppy bushes you can crank 1 end more than the other to give you the "compound" curve View attachment 78865

I wouldnt even raise a sweat on your job, pretty sure I could wind a 3" radius on mine, but that would be about as tight as it would go I reckon.
Its not that strenuous to do. If you try to push it too hard it just gets too difficult to crank the handle. Just go back and forth adding a bit more pressure each time to tighten the curve.

I have that exact same roller myself, good to see another still in use.

Thanks... LOL, some of my first publications and early development products were cell phones and related ground infrastructure (I worked on the original "bag phones" and later did much of the Vo-Coding for the first Motorola Star-Tac cell phone -the very first "flip-phone"). I hated portable phones back then -and still do. They offered to give us the experimental phones free, usable on an experimental network -and I wanted nothing to do with them. A modern day Luddite for sure...
