Topic tags/keywords: jointer

I started another thread about 8” jointers and an interesting point was brought up -

I’ve got a basement shop so moving large tools down the steps, and around the landing, is difficult. I usually hire a couple of movers to do the heavy work, but it’s not cheap, and scheduling the delivery so the movers can be there and not risk having the new tool sitting outside overnight is a real pain.

Someone suggested removing the beds to make it easier to move. Does anyone have any experience with how hard it is to remove and reinstall the beds (particularly on a Grizzly G0490ZW)? I’m moderately mechanically inclined, and have your typical tool kit. I’d hate to tear apart a new machine only to not be able to get it back together properly.

Any thoughts would be greatly appreciated.

I just finished watching this, I don’t know if it will help but it was interesting to watch except for all the talk at first. Skip up to 4:48 in the video.

Thanks for the video link. I did see that on youtube.

Just to clarify: The top portion of the G0490 is about 350#; I’m actually asking about removing the infeed bed and outfeed bed from the top assembly (leaving the cutter head with the rest of the top) so I can move them as three separate pieces (in addition to the base with the motor.) That way I can move them myself, or with minimal help.

jmos,

It sounds like you now have or are about to have a new machine. If so, congrats on the new machine!

I have never removed the beds on a parallelogram jointer but would ensure I had no other alternatives before doing so. In addition to worries about properly re-installing the beds, aligning the beds would most likely be required (although aligning the bed may be required anyway).

Before removing the beds, I think my first step would be to contact Grizzly and speak with jointer technical service. Their customer service enjoys a good reputation and their explanations and tips could prove invaluable. Also, as you proceed, you may have the name and telephone number of a Grizzly contact person who can help you overcome any difficulties that may arise.

My approach to removing the beds would be to take my time, try to move the machine and re-install the beds all in the same day while things are fresh in mind and carefully document each disassembly step.

Having the exploded parts diagram from the manual at hand would help determine what to remove and perhaps even in what order. Also, any errors or unpublished changes could be noted for when re-attaching the beds. Rigidly adhering to a system that keeps bolts, washed and nuts organized or re-installed in their original place after the bed is removed can keep things from getting too confusing. Another thought is to video the disassembly, ideally a friend running the camera while you do the work. If things get confusing when re-assembling, the video could clear up the confusion. As an alternative to the video would be a series of photos.

It seems to me that keeping in mind that the beds are heavy would be important. When the last fastener is removed, the table could shift, maybe hit the floor and even cause an injury. Therefore taking precautions against this eventuality could save a lot of aggravation.

After looking at the parts diagram for the G0490XW jointer, my guess is that if nothing is damaged during the surgery, it will go smoothly. The attaching system seems to be fairly straightforward although lacking some of the detail I seem to need. However you may find that the cutter head must also be removed so the beds can be lifted and positioned from the ends.

I did contact Grizzly and just got a reply (about 24 hours, not bad at all). Their recommendation is to not take the tables off if at all possible. I guess I’ll just hire movers and hope for the best.

JBrow, thank for the thoughtful response. I agree, it doesn’t seem too bad looking at the parts diagram, but the downside if I mess it up is too big to risk. This doesn’t seem to be a common thing, as I can’t find anything online about removing the tables.
