Just did this mod
and it is running so much better. With the speed i was trying to push it at (100-120ipm) it was rattling the nuts off due to all of the turns I believe. with this, it doesn’t seem like it is going anywhere. the cost was a bag of 100 nylock nuts which is around 6-7 bux on amazon. Did some test at 75ipm with a new router bit since my other ended up burnt after being plowed through the material. I ordered this Amazon.com and it is cutting like butter. With the stability and as smooth as this is cutting, I think i will bump it back up to 100ipm
