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.

@886014 4 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.

CHAMFER MEISTER: Rather than use oscillation, rotate your v-block around the normal of the belt-plane so that it makes a 10° angle. I think this will work well if two things are considered: 1) The angle remains small. 2) ratio of speeds times belt length gives a small periodic distance: d = (V_part/V_belt) * L_belt (d) would be the distance between high/low spots along the chamfered edge.

On the Chamfermeister wearing a grrove in the belt of the sander arrange the V that the work piece slides in to be a long diagonal on the belt. In that way the wear should be (more or less) evenly distributed across the width of the belt. You might have to do some major re-design of the setup though. ETA: now I see that Seal Piercing said basically the same thing.

At where I work we use an old Smaller Astra tool and cutter grinder at with a diamond cup wheel at 45* and a large * riser * steel block on the table.(with a lot of material removed from the back side because the bottom 3rd of the Cup wheel is inside the large steel block) On the top of the steel block there is a right angled block (with the bottom paralleled the table) with most of the inner corner cut off (it’s whole at the two ends and 3mm ish slot going through the corner) and the wheel is basically in the bottom steel block at 45*. You run your part across the top right angled and the cup wheel at 45* cuts a chamfer in. You can control the chamfer size with the Y axis and sometimes put masking tape on the bottom and side of the right angled piece to prevent the bottom or side of the part from scratches. It’s great for tool steel
