Slip Roller

[sstec]

OK as promised, here are a few pictures and layout of what “I” did to build my slip roller.
Right or wrong this is what I’ve done, re-done and still need to re-do some more.
First picture is the pattern I drew in Plasmacam. The 2 side plates are cut from ½ HR steel. The gears, washers and adjustment stars are cut from 10 CR steel.
The rollers are made of 2” schedule 80 black pipe and the roller shaft is 1”.
The rest is 1 square tube.
The only parts I needed to buy were a few more shaft collars, $8.00.
The rest is scrap and leftovers.

What I need to do next is reinforce the washers on the shaft inside the pipe.
I see it flexing some on heavy ga. material.
I think it would have been ok if I was not rolling 10 ga. HR 12 feet long.

The end pictures show how I adjust the feed roller and the pressure roller.

Anyway, works for what I need it to do and all I have in it is $8.00.

Thank you for yet another great show & tell, sstec.

I don't know how much strength it would add but you could try making donuts to fit over the 1" and slide fit in the schedule 80. Weld donuts to shaft. Drill schedule 80 and weld assembly in pipe.

Very nice build. Are there bearings or bushings for the ends?

tenfingers,
I did that times 5 per roller 1 on each end, middle and then in between.
I made my own washers out of 10ga CR steel. I will need to either double or triple them up or cut some out of 1/4". It would have been OK if I was rolling 16ga or less but 12 ga - 10 ga takes a little HP...........

lwhiway,
No bearings or bushings on this one. Just tool steel 1"shaft with 1" hole and shots of oil at each every time I use it. Evolution as I go, if it breaks fix it. Will wait and see how long it last before I need to re-build or find parts to improve the design. For now using grade 1, 1/4-20 bolt on the roll handle so it shears off before too much damage is done. The only problem with that is location of hand in regards to face when it breaks........... Pop myself twice now..........

1" inside the rollers, 2" outside the rollers, how are the two connected since it seems to me there is a space that needs to be equally the same. Maybe I am missing something here.
Serious question, what would you charge to cut out the said pieces on your plasma cam? Includes what your steel costs and then I pay shipping. Seeing as I don't have 9 thousand laying around (but if I did, I have looked at a plasma cam and have drooled!) efficient use of my resources means I have to go to a source which at this time is you.
Very nice work, not expecting you to cut parts and me only have 8 bucks in mine, but do see a possibility for you to sell a few. Let me know.

JWS,
Attached is a detail drawing, see if that helps........
I used 10ga for the washers, I need to either use more or thicker steel.
I welded them to the shaft then pressed the shaft into the roller tube, sure helps if every thing is straight.
Start looking for your parts and then let me know in case you need to change something before I cut it out.
This has worked for me, but if I wreck something I can re-cut it....
My current layout is for 1" shaft and 2" schedule 80 pipe, so the washers and gears as well as the 2 side plates are set for that.
If you find parts, cheaper, i.e. 1 1/4" shaft or 2 1/2" I'll need make some changes.
One other thought is how wide do you want to make it? wider = more washers...

let me know,

That's about as nice a set of rollers as I've seen for such a low-buck investment. Simple and effective. I'll definitely keep some of your design aspects in mind when I get ready to build a set of powered rollers.

Have you had any problems with them flexing under the load of thicker metal?
As much a 1/8 in?
Obviously, the wider you go the more "meat" you would have to put into it.

What is the minimum diameter you have rolled with your existing setup?

Photomask,
Yes I have some flex gonig on. That's why I need to cut the side off and use thicker washers and more of them inside the roller tubes.
Like stated before, if I was only rolling 16ga or less, it would be OK.
As far as minimum diameter, 3" with 16ga.
I did not build it to have the top roller come off, that would make tight rolls easier to get off, I was going more for thicker stuff and not so tight.
