As a means of pointing to a suitable material the possible heat generated should ideally be of almost no consequence, at certainly shouldn't be a concern for any detrimental structural issues it might cause (i.e. anything that might get hot shouldn't care). oh and +1 :-) | |
| Feb 26, 2022 at 14:43 | comment | added | user5572 | @Graphus I think we are in agreement and I just wanted to point out that PVC is, indeed, rather unique in how it handles heat making it the least useful material for this purpose. I've rolled up the hive-mind thoughts into an Answer because why not? | |

| Feb 26, 2022 at 5:38 | comment | added | Graphus | @jdv, that's some of what I was getting at. But for a fixed paper type, wear on the abrasive and the setting of the roller play a massive role in differences in heat generated. Meaning it's easy to posit a single design that works fine initially and then a problem shows up later..... so bottom line, wood will solve all these issues (in addition to being far, far stiffer). And FWIW almost every DIY sander has a wooden drum, so there's that. | |
| Feb 25, 2022 at 20:37 | comment | added | user5572 | There are a lot of variables here. How hot do different papers/meshes get? Does the paper or glue backing change anything? And so on. Thermals are hard. This might mean only your experimental evidence might hold. What you are concerned with is the "HDT", which for PVC is probably too low for you to use like this. Maybe ABS is a better choice? | |
| Feb 25, 2022 at 20:12 | comment | added | Graphus | Well experientially PVC does soften enough to distort at temps I would have estimated to be approx upper 50s or low 60s (based on other relevant temperature markers I'm familiar with). But whether this is a temp range your drum will reach in service nobody can say since there are unknowable factors. I would suggest you just make your central cylinder from wood so you can avoid the issue entirely, or, make a slightly smaller cylinder that you can glue inside the PVA pipe to support it. [You don't need a lathe for this.] | |

Save you the time and material of the 3D print. You might want/need to drill some diagonal holes through your wheel to allow for some cooling effect. | |
