A question for those who have used the KSJ Venture 30 to 50 upgrade with the aluminum headblock. Have any of you experienced a looseness of the headblock on the shaft??

After installing mine, I noticed that the headblock is rocking slightly around the bolt that holds the block on the shaft. The amount of movement is 12-13mm at the tip end of a 600mm blade. The bolt is TIGHT, so thats not the problem. I had someone at Fall Fest mention drilling a couple of 3mm holes at right angles to the head bolt and using set screws to lock down the motion, but I'd prefer to aviod that if possible.

As always, thanks in advance for the help!!

head wobble
yes i had the same problem on both of my machines. yes you have to hog down on the cross bolt, but i did find that if you put a small amount of blue loctite on the shaft prior to assembly, it will take most if not all of the play out of it. dont worry you can get it apart again incase of a mishap. hope this helps.
