I would stay away from round rails, even mounted ones. The round carriages just don't have the minimal backlash that profile rails do. Something like these: https://www.amazon.com/ReliaBot-Linear-Carriage-Printer-Machine/dp/B07B4DWWZC/ref=sr_1_1_sspa?crid=2MZBCRDI7FCWP&dib=eyJ2IjoiMSJ9.Llw_TKV7mmhxPx67bYg1ZJfyMppRTvf1VZfWN-_dBrQY6Ol53Z4t7Y3fnYOKj7gI63L6wxYgn30m60q-e3tdQwy8_RorDkDpywOceuJsg1s2GPvNZNKnfnPjB3nA7Udt88v7OHhY7qemDcP7ZYt3ybuwPqnayOvcBz-GdEWgU6dkf38Jx9zpBse0ZPKFdQ6acvRRc6cm5KcC7F83cx7s8N4nivSX-y_ujWGi0dzv14vuh9poOFOX0gLNfb71mDFFMrTNs1XJnB71i1znMtc-bsIiPNDvXj1ZS43F75Rzzyg.N2NFCOlkzYK-hEGLNffnZvPJH8xaAa152ChVYNNSLDM&dib_tag=se&keywords=size+12+linear+rail&qid=1750385121&s=industrial&sprefix=size+12+linear+rail,industrial,127&sr=1-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&th=1

If you do design for these, it is suggested to have a reference edge on one side that you can push the rail to. Tighten down that rail, then 'float' the other rail in using the components that tie the two together. You can get wide rail that has a decent amount of rigidity about the x-axis of the rail, but having two spread as far apart as possible will add to the stiffness.

I did not intend to say that the rails are the only issue, apologies for any confusion. The rails may add to the problem.

If you decide to tweak any of your designs, you can easily model in space to add metal angle or bars to add rigidity. You could also the basic outer shape as a thin-ish 3d print and fill the voids with epoxy mixed with tile grout, which will give great rigidity and damping.

Finally, if you have large areas that would use an infill, you would be better off creating an internal matrix of structure aligned to counteract your predicted bending forces. Look at how airplane wings are built, they have spars the entire length of the wing and ribs perpendicular to the wing box. Bridges are the same.

PLA is a very stiff material and very good in compression. Adding aluminum plate or angle, bolted and epoxied to the outer sides of the the item will give a lot of tensile strength (CF would also work).

Feel free to PM me if you want to discuss more in private.

All great suggestions. And yeah, those linear rails do make more sense than the round ones. That style seems to be common on Voron builds (which I would love to do a tool changer one day! - Whole different topic.) I So far everything on this lathe (edit: said printer) has been done with PETG, it's been my go to for materials that are likely to see harsher conditions. I have an ANL fuse holder for a few larger circuits under the hood of my Chevelle that are fairly close to the headers made out of PETG for the body and TPU for the lid. It's been solid for a few years. That may all change as I play with ASA and ABS more, now that I have a new printer for the farm that's enclosed.

Either way, back on topic, thanks for all the info. I'll definitely be PM'ing you soon to help me brainstorm!

I enjoyed Billy Walter's book. I also enjoyed Artie's posts on ONE POCKET ORG. I always wondered if they were friendly or not due to the similarity of their professions and experiences.

When I met Artie in 07-08 he wasn’t friendly with him then. I’m not sure they were ever friends. They were in the same biz and there was friction between them as they were both chasing value bets and information, they were competitors. They weren’t friends.

That’s what I picked up listening to Artie. I have never met or spoke to Billy Walter’s. I know guys who were runners for him-some well known people in the pool world. (I can’t say who, but you’d be surprised - this was before I came to town in 91). Vegas was a small town.

Billy learned a few tricks of the trade from Artie, that didn’t sit well with him. But it’s a rough biz they were in-in that era and guys did what they had to do. They weren’t going to yoga together-that’s for sure!

Gambling, wagering, hustling, there are no universal black & white truths in these definitions. Some may have problems/issues with their own definition is to what these words mean. I have issue with a cheat and none of these words mean that to me… that’s my truth.

I used to fish a lot. When I tossed out something tasty or that looked tasty I didn't advertise it had a hook in it. When I went in a bar or pool hall and started tuning up aiming the medium difficulty shots and harder at points, well that was just hiding the hook. Nobody had to bite and I had a set of ethics that included not raising the bet over five dollars myself. Sometimes the bet started for much more but if a banger came in off the street and wanted to play for three or five dollars he didn't get hurt. If a hustler craftily stalled until he had massaged the bet up to twenty or fifty a game and then found out he was the little fish, well... Big fish eat little fish as the great Smorg always said!

Funny thing, until I came on AZB I never considered what I was doing hustling. Hustling was an active hustle in my mind, I wasn't actively stalking suckers or jacking the bet. Back when I was a beginner I was told that hustling was what pool players did so I tried an active hustle. Made a few dollars but it left such a bad taste in my mouth that I didn't try again for six months. Made a few bucks again, still didn't like it, that was my last active hustle over fifty years ago!
