Topic tags/keywords: table saw grizzly g0478

My table saw seemed out of alignment. I got out my Master plate and dial from front of the blade to back of the blade is off by .01. The manual states: Loosen the trunnion bolts shown in Figure 57. Under Figure 57 it indicates 6 bolts but it also says “not all the trunnion bolts are shown”).

Does anyone know how many trunnion bolts this saw has? I can only locate 6. I loosened the bolts. With the bolts lose I was able to adjust the trunnion assembly get the measurement down to .03 but that’s all. I’m very frustrated with this, can anyone help. I’m trying to contact Grizzly but their tech support doesn’t have a 1-800 number and I don’t have long distance so I’m in the process of email them.

Can anyone with this saw help me out?

Thanks
Angela

Hi Angela, You need to learn all about saw alignment now. Don’t know what the original problem was. If there’s a problem with the saw, the alignment process will uncover it.

If you want to make your saw as accurate as possible, I recommend these.
and this site. The PALS will work fine with your saw and mostl agree they are worth the $20. Ed Bennett seems to make some people agitated but if you want to learn all about saw alignment, his site is one of the best. You will need to register and sign in but there are no pop ups and no spam.

Search ‘alignment’ in the forums and you’ll get all kinds of information and opinions. I suggest, 1) Put the Master Plate back in the box. 2) Check the arbor and flange. 3) Install the PALS and adjust the trunnions (on both planes if needed) to get the blade parallel to the miter slot. 4) Align the fence and miter gauge. Good luck. -Jack

slightly loosen the bolts you can find . take a rubber mallet or dead blow hammer and hit the corner of your table top in according to which direction it has to go. Dont get frustrated,walk away from it for a couple of minutes if needed.

Thanks for the response. I look into the information you provided. I’ve check the arbor and flange and both are almost perfect. I discovered there’s only 6 tennions and I have those lose but I still can’t get it to work. I think there must be something else going on. I haven’t even worked with the fence yet since I can’t get the blade and miter slot parallel. Thanks again since so far Grizzly customer service has been basicall Non-existent.

I just looked at PALS and it’s for contractor saws mine is a cabinet saw. I’ve tried the hammer thing before even going to the Interent. I have all the articles about tuning up the table saw. They all say loosen the tunnions bolts and make the adjustment. It sounded easy until I actually loosened the bolts, tried hitting it and it didn’t change it enough. I then loosened the bolts so much I could twist them by hand. When I first got the saw it was off by .003. When I check it now, a couple of years later it was .010. After loosening the bolt I was able to get it to half that but that still way off. Does anyone know what else might be the problem. It’s not slightly off it’s way off. I was wondering if anyone might know of another problem that might be wrong with it. As noted above the arbor and flange is fine. I’m still waiting for the Grizzly tech to call back.
Thanks
Angela

Hi Angela, Before I posted I looked at the G0478 manual. and the pl .(I am envious) As I understand it, the G0478 is a hybrid and the trunnions bolt to the bottom of the table like a contractor saw, so the PALS should work on your saw. Ask the Grizzly tech when he calls or talk to the PALS folks .

Twiceisnice is right about not getting frustrated. Take your time. step by step. your saw will be better than new. Good luck. -Jack
