For someone like me who did not go through a machinist apprentice program, this video was worth a lot. The tapping, use of the 1-2-3 block for datum reference, the filing, paper on the surface plate, the fillet meister AND the sheet metal shield around your table put a lot of useful information into a very few minutes. Thanks again for a really useful channel.

I buy a few different blunt tip sizes from ~24 to ~10 gauge for accurately applying adhesives, lubricants, solvents, thermal compounds, etc. Been watching religiously since near the beginning Rob...have built a passable university machine shop on the knowledge gleaned from you, Tom, Ol' Tony, Stefan and Adam.

Thanks Rob, looks great! I liked the plastic bag on the calculator trick. Consider that idea stolen ;) I'll offer a trade of suggesting modifying your chamfer jig so it's not square to the belt. Unless draw filing we don't normally file along the part axis, so no need to sand precisely along it either. Chances are a slight angle wouldn't even be noticed in any case.

@8860144 жыл бұрын
@@ROBRENZ Very good point Rob. However I don't mean to go crazy on angles, and just a few degrees will spread the wear area over the belt of that length considerably and I've never seen any burr when done like that to be quite honest. A machine like this has been something I've wanted to make up for a long time. I currently just use a belt grinder freehand and instead of yet another tool to take up space, may make up a jig to do this type of operation. My grinder has good facilities to allow tables and jigs to slide on/off BTW, no connection to this company, but this is the 48" belt grinder I use and it's from a Sydney, Australia company. I think you will appreciate some of the simple yet very clever engineering functions he's incorporated www.radiusmaster.com.au/belt-grinders/radius-master-48-series-belt-grinder/ I think they export around the world.
