Topic tags/keywords: question

A while back I bought a used Grizzly G0454. It seemed to work OK at first but then it started hanging up and not letting the wood go all the way through. I downloaded the manual and started going through the cleanup and adjustments. I have set the blade heights, and double checked them. But when I put the dial indicator on the table and check the blades from side to side they are ~.015 off . To me this says the table is not parallel with the cutter. Do I have to move a sprocket or two on the chain underneath? It kind of seems like moving a tooth would change it too much? Anyone run into this before and fixed it?

To me, it sounds like you just don’t have your knives set properly. At any rate, that should not cause the stock to hang up when going through the machine. Have you tried cleaning up the feed rollers and waxing the table?

Cheers,

Thanks for the reply Brad,

I am a rookie at this stuff, but I made a couple of holders for my dial indicator, and when I measure the knives from the top based off the cutter head it reads within 1 to 2 thousands from side to side, but when I measure from the table to the knifes it is off the 15 thou side to side.

I have cleaned up the feed rollers and will wax the table when I am done adjusting, but this has got me kind of hung up.

I checked the manual, and it does say to reference the knives off the cutter head… so you might be right about the table being out of whack. Because of the design, I guess it could be possible to have the chain skip a tooth if it was loose enough (there is a section about proper chain tensioning in the manual). I got no idea what the TPI on those elevation screws are (or how many teeth are on the attached gears), but I can see how skipping a tooth or two might be enough to get the deviation you observe. For example, a 16tpi lead screw with an 8 tooth gear would mean a single tooth would move the table about 8 thou of an inch. Doesn’t seem like it would be too difficult to loosen the chain and rotate one or more of the elevation gears +/- a tooth and re-check with your indicator.

Cheers,
Brad
