so the handle will be metal/wood lather operation.
the channel/bracket and the roller - all metal. no plastics.
the approximate pressure and use will be similar to that of the wallpapaer seam roller.
and lastly - if i can resolve this issue in the design and move forward - the goal will several hundred units at first. if i can market it well and proves successful - then definitely a few thousand thereafter.
░
also - i am living in iceland and it'll be costly to manufacture here. i am beginning to source out manufacturers throughout europe and states. i need to start some cost estimates
do you have recommendations for any machine shops to contact?

Maybe a domed starlock washer, which would push onto a solid shaft, would fit your requirements.

this looks impressive. i guess my only concern would be - if you accidentally dropped the tool, say onto the floor and the floor met the roller - would these things just pop right off?
if not, then these might actually do!

For prototyping buy 1m to 3m lengths of tube with a slightly smaller hole than you think you need. Cut to length yourself with a hacksaw, holding the tube in a vice, use masking tape to mark the length, wrapping tape around it makes it easy to mark a straight 90 degree cut, cut slightly over length and file to size.
You can use a hand drill to open the hole up if required, once you have a definite set of dimensions ask for quotes from machine shops in your country, you're into a minimum 1000 parts so it's viable for professionals to quote.
Avoid getting too caught up in being able to download part models to build your product in CAD, model the tube yourself and have it made once you've prototyped it and have working dimensions.You think that's too expensive? You're not a Model Engineer are you? :D
