Drain pipe roller

[Jeremy Poulter]

Hi,

I would like to mount some 32mm pipe inside a 68mm drain pipe to make a (hopefully) cheap roller. So I need some spacers to glue to both pipes to keep the 32mm pipe in the middle and add some more strength. So my question is, what is the best material to make these out of and what is the best glue to use to attach them? 

I would really like to be able to laser cut these  spacers just for ease of manufacturing them so my first thoughts were wood, just some 6mm, maybe 8mm, ply, but is there a good glue that can be used to attach them? Any other good candidates?

Try standard pipe solvent. If you make it a fairly tight fit, the plastic will melt into the spacers you make. Or just make them push fit with no glue at all...?

Just an observation:

That outer material doesn't look very thick/strong for roller purposes, have you handled it to check it strength?

If it is thin enough to deform under pressure, you may want to fill it with clay or something like that to make it more sturdy..

Is this for a lawn roller? What will you use to give mass?

Structurally PVC cement to PVC is strongest but you can't laser cut PVC. Wood can be bonded to PVC but not as strong and more expensive glue.

Why not use concrete as both the mass and structural element?

one spacer at each end and fill it with cement? Epoxy the spacer at the bottom.

No not a lawn roller, more of a roller blind, so doesn't need to be heavy, just roll up a 2m wide cover.

Cheers,

Jeremy

Maybe then use expanding polyurethane foam instead of concrete. With a lighter plywood spacer structure to stabilise while setting and seal ends.
