Something that I've wanted for a long time is a really powerful belt grinder, but the commercially available machines run around $3,000 for the good ones. It could be argued that that is a reasonable price when I factor in the amount of time I spent on this project, but I had a month of relatively little work (a good thing, sometimes), so I banged this thing out. It will run a 2" x 60" belt at 8,000 feet per minute:
Here is a detail of the belt tension and tracking mechanism. The dark green knob preloads the spring that is used to tension the belt. The yellow knob changes the angle of the tracking wheel, which allows the belt tracking to be adjusted side to side.
The grinder in its nascence.
Fixturing the two halves of the contact wheel frame. The cylindrical members are just spacers to hold everything in place while I welded it all together.
The work rest/table. Extra heavy duty!
The contact wheel and work rest installed. All the fasteners shown here are 1/2". Probably overkill, but I wanted it to be super rigid.
Below are shown some new brackets for the Flanger. These will allow two more booms to be attached to the center hub, so that four people total can ride it.
These box tubes are for a piece of rigging for my neighbor who does live sound and light production. Up to a ton of speakers can hang from these frames.
The mess made by drilling a hundred and thirty-six 3/4" holes. Drilling all these holes allowed me to experiment with cutting feeds and speeds. I think I might have smoked my $70 drill bit, but I learned a lot in the process.
