Great, easy fix. You had me going with this fix so I checked my mill. 1. I moved my "fix" pin away from the belt and made sure that the WM pin was 1/8" away from the tightened belt, just like yours is now. Belt started to flop and bang just like before. 2. Put my "fix" pin back with about a 1/4" gap from the tightened belt. Flopping was reduced and there was no banging. 3. Compared the position of your pin @ 1/8" with my WM pin @ 1/8" and found that your pin looks closer to the sheave and at about the 7:30- 8:00 position whereas my pin is 1 1/8" away from the sheave and at about the 6:30 position. I'm thinking that this is why my mill bangs and your doesn't. 4. I moved my pin (the pin I made is closer to the mounting hole than the WM pin) to the WM pin location and the drive belt had a tendency to grab and move the blade at idle. NOT a good thing. It looks to me like my WM pin bracket needs to be a little shorter in order to put the pin in the same relative position to the engine sheave as your pin. One final thing......... when am I going to see some sawdust? Dave

There are a few bugs I’m working out on this unit. But I’ve been plowing through some stuff the past couple days. After watching your video the pins factory pins do look a little different. I suspect WM realized the issue and resolved it.

[@TheOldManAndTheSaw]

@@DustyRanch I'm calling WM today to see if they have an upgraded pin assembly.

[@DustyRanch]

@@TheOldManAndTheSaw what did you find out?

[@TheOldManAndTheSaw]

@@DustyRanch I found out that WM doesn't have an upgraded fix for my issue; so I fixed it.

[@justinbyers1441]

Solid fix man, atleast it wasn't anything like real bad... and man i can't wait to actually see this thing in person

[@DustyRanch]

It’s definitely a step up.

[@aronsmith4768]

Timely. We are fighting a similar issue. Also the contact (copper strip) for operating the hydraulics has become pitted and makes operation a PITA.

[@DustyRanch]

Keeping that contact adjusted and the sawdust off is key. It’s a bit of a headache but as someone who ran a manual mill 7 years before the hydraulics upgrade, I would rather deal with the copper strip 💪.

[@TheOldJarhead]

What problem were you having? Just the knocking sound? Or was the belt slipping?

[@DustyRanch]

The belt would actually slip to the extent that it started smoking the belt a couple times. Has not done it in several hours so I’m assuming that was all it was.

[@TheOldJarhead]

@@DustyRanch wow. never had that happen

[@DustyRanch]

@@TheOldJarhead gentleman down the rd picked his up the same day. Had a very similar but apparently more serious issue. Took his back to have WM work it out.

[@TheOldJarhead]

@@DustyRanch Wow crazy! I am guessing it's the rush to get them out!

[@DustyRanch]

@@TheOldJarhead that’s my guess too and the lack of parts due to supply chain disruption.

[@olddodger7178]

Have you been in contact with Wood-Mizer?

[@DustyRanch]

They told me how to fix the issue.

[@aronsmith4768]

Which engine do you have?

[@DustyRanch]

Gas EFI

[@johnclark5153]

Mine still does it. This is a stupid way to disengage the belt. There should be a electric clutch. For the cost of these mill the pin lifter is not an acceptable method.

[@DustyRanch]

I am not a huge fan of the motor moving. Not sure why they deigned it that way but I assume they have a reason. Check out “the old man and the sawmill” he has a good solution.
