Yesterday I planed four 13' long QSWO boards of varying widths on my G0453Z 15" planer. I noticed a slight variance in thickness on a couple of the boards even though the height setting was not changed.
I called Griz tech support; the gentleman told me this was a common issue where long/heavy stock was run through without adequate in/out feed support (causing the table to lower). The table is locked by 4 wedges pulled against the 4 columns when the locking knobs are tightened.
I noticed that even when the knobs are tightened hard it is still quite easy to change the table height by turning the adjustment wheel. It’s easy to understand how long, heavy stock could cause the table to move if not perfectly supported.
We had used 2 roller stands for the task, each positioned about 5 feet from the in/outfeed tables. Perhaps the roller stands need to be moved closer to the tables. Probably better yet to add 2 roller stands, 2 each at the infeed and outfeed ends.
I'd be happier if the G0453 had a better design to positively lock the table (as do the high-end Griz planers according to the tech). I guess this is one of those sacrifices I make in seeking out both low cost and value. I'll be more careful next time I plane heavy/long stock.
Not a complaint against Grizzly...just an ah-ha moment I thought I'd share.
