I am building a brass annealer using an old rotisserie motor. Seems to revolve at about 7-8 seconds. Will this be the right speed for ‘06, .30-40, 6.5x55 brass? Or do I need to add a Harbor Freight variable speed control to speed it up or slow it a little? Going to do the split finger way to grab the next case from the feed ramp rather than a separate feed wheel to drop a single case. Seems simpler. This idea.
