Sorry to hear that a few of the 490 folks are not real happy. I picked mine up at Grizzly and everything was fine. The problem is shipping them with the motor attached. According to PaPa Griz, they used to ship tools with the motor bolted to the pallet, but there were to many whiners. So Grizzly tried to make it good and save a little work and this is the result. These shipping companies are very hard on these packages. I just got a package through UPS and there were tire tracks on the box. The box was smashed, but everything inside survived.
All I can say is that if I would have received one with bent struts, I sure would be running it until the new base came. It took me about an hour to assemble everything and with 3 people lifting the table to the base took about 5 minutes.
Make some sawdust with that hunk of iron!! It is a fine machine, best buy out there for an 8" jointer. I looked at them all including Powermatic. Powermatic's six inch is way over priced and the one I looked at was very cheaply made. As far as their 8" with the parralogram beds, come on its not worth what they are asking. You are just paying for the name. Still made overseas and I would put the 490 up against it any day.
If Grizzly is replacing the base everything should be fine and you guys should enjoy the 490 for the rest of your lives. We all took a chance, we knew it was a new product and there would be bugs. I remember some of the early post before they started shipping them and we all had concerns. Most of the problem is with the shipper not the machine. Shiraz will make it right.
I will say one thing, it took a month to dull those knives and that really surprised me. I thought for sure that they were cheap and would be nicked the first day I used them. I was wrong. 30 days later and well over 1000 brd ft of hardwood, they are getting dull but no nicks!!
Good Luck,
Michael
