Hello -

I am new here.? This is my first post.?

I have an FB510 band saw and I have been having problems with blade drift especially with wider resaw type blades.? I was given a tip by a fellow named Bob at R&B Bandsaw to check out this video ?

and related article ?
by Michael Fortune.?

So I began by adjusting the fence clamp bar so the the fence is very well aligned as parallel with the miter slot and blade slot. ?

I proceeded to do the cutting tests and the wood is tight between the fence and the left side of the blade. As such the blade is bowing slightly to the right of the operator.? When I stop the saw in the cut, there is a small gap between the right side of the blade and the wood and of course no gap on the left side. ?

Based on the information in the video and article, I conclude that the table (and so too the properly aligned fence) are out of alignment (not parallel) with the blade and in this case turned a bit too far clockwise from the perspective of the operator looking down at the table.?

Given this, my desire is to adjust / move the table top relative to the blade (and so relative to the rest of the saw) such that the table top would be rotated very slightly counterclockwise from its current position.?

Initially, I mistakenly thought this could be accomplished by loosening the 4 bolts holding the table top to the semi-circular base below it (that base piece is the one that can be unlocked to allow the table top to be oriented on an angle to horizontal) and then just shift the table top as I wanted and retighten (similar to the procedure described in the video). ? The table top cannot be shifted like that because near two of the 4 bolt holes mentioned there are also little placement pins that stick up from the semi-circular base into small holes in the bottom of the table top; these hold the table top such that they exactly align all four bolt holes in the table top with the corresponding semi circular base below. ? As well, there is no play between bolt holes and the bolts; the table top was not intended to be adjusted this way. ?(I tightened the 4 bolts back up).?

I notice that there are a pair of bolts which attach the semi circular base piece to the frame below it, and I wondered if there was some play and possibility for adjustment there, but I thought I should try to find out from somebody who knows before trying anything further.?

So, please tell me how can I make the such an ?adjustment in the table orientation??
