Olathe 12 pto Wood chipper

[cairologger]

.200 Blade height .045 blade to anvil clearance. 7/16" drop table to drum blade clearance. It was over 1/2" and would not self feed. but now will self feed up to 2" stuff well but not larger. The in feed table is concave under the drum, is this right? And 7/16" is as close as I could get it with out modifying the table stop. what's wrong here? Thanks, Jake
