I hope someone reading this will be able to help a fellow woodworker and reader of this blog. Here is the problem with his new band saw:
- He adjusts the guide post that holds the blade guides to resaw a 4-inch thick piece of wood, and is able to make perfect cuts.
- Then he changes the work piece to resaw an 8-inch tall piece. The blade guide is way off — it is so far off that he must re-adjust the blade guides, to provide proper support for the blade.
- He tests the guide post, and it is “sloppy” in the steel enclosure.
- He thinks that the guide post bracket is too short at about 5 inches, and requested I measure mine, including a photo. Here is mine — the one on my band saw is between 4″ and 4-1/2″ tall (for visual reference, the wooden gnomon is exactly 6 inches tall):
- I tried to move the upper guide column on my 17-inch Grizzly band saw with my hand; it is very tight in place, and cannot be moved except up and down using the crank located outside the wheel cover.
- In addition, when I move the guide column up and down, the entire blade guide assembly stays true, and does not require any adjustment.
With my limited troubleshooting, now I believe that our friend and reader has two problems:
a) First, the “slop”, or play in the guide column must be reduced to close to nil. Will this require some shims, or machining of a new part? And
b) The vertical alignment must be fixed using the bolts accessed from outside the upper wheel case
Request: Although I have good working knowledge of the band saw, I am not certain I am 100% correct in my assessment of this problem. Therefore, so we can better help our fellow woodworker, I request that YOU, the readers of the blog, provide additional feedback either in the Comments section below, or via e-mail to me at firstname.lastname@example.org. Thanks!
