« Part 3: Assembly Issues Part 4 of Grizzly G0452P Jointer Set-Up series no next part

When assembling the fence for the jointer, you need to place the fence on the table in order to have clearance to insert and tighten the screws holding the fence bracket to the fench carriage that rides on the “ram” (the rack-and-pinion steel post):

I noticed upon installing the fence, that there was a lot of play in the fence, but that the default position it wanted to settle at was with pretty uneven gaps at the infeed table side vs the outfeed table side, even with the infeed table set dead flat with the outfeed. I also had left the wax paper on both the tables and the fence to protect them somewhat during the assembly. Obviously I had to crank the fence back off the table once it was installed to perform other assembly operations like installing the cutterhead guard, and to ultimately remove the wax paper, clean off the cosmoline, and start checking the tables’ alignment.

Upon doing this, however, I noticed these unsightly scratches in my outfeed table just past the cutterhead (reminder to right-click and ‘Open in New Tab’ to see the full picture):

This was bad enough, but once I tighted the set screw on top of the carriage surround the ram, I realized that this made the ram, and hence, the whole fence assembly want to rotate toward the outfeed side, i.e. it forced the outfeed side down and raised the infeed side of the fence up. If you don’t tighten this set screw, the fence has a just a ton of slop.

Well, if you keep the set screw tightened, you run into the problem that the outfeed side of the fence bracket won’t slide onto the table because it is too low, while the infeed side of the bracket has plenty of clearance:

I should also note that I checked the outfeed table, and it is dead level with the top of the knives at top dead center, so it is not a question of adjusting the outfeed table down. The only way to get the fence to slide out onto the table is to loosen the set screw so there is a ton of slop in the ram, and then hold the fence up on the outfeed table slide as you turn the knob with your other hand. Of course, once you let go, it still wants to rest with that outfeed-side half of the bracket resting on the table top, while the infeed side floats above it.

I checked the bracket that the ram assembly sits on to see how it was aligned relative to the table, as you can see, it is slightly below:

As you’d expect, the other side is slightly above.

Anyway, so it seems I have two issues. First, that this bracket isn’t flush with the tables on either side. This probably wouldn’t be a problem if it weren’t for the second issue, which is that the ram and fence mounting bracket attached to are skewed to drive the outfeed side down, which of course is the side that is already too low.

So I obviously plan to call Grizzly technical support about this and will post an update as to the outcome of that conversation. But for now I have an unusable jointer fence that has scratched my outfeed table.

Thanks for reading!

I have the same Grizzly jointer. I’ve asked their tech support the same question and the answer is that the fence is supposed to rest on the outfeed table. Yes they know it scratches the table. You could add a piece of super slippery HDPE tape to the underside of the fence (I didn’t) or sand the spot on the underside of the fence with 220 grit like I did so the damage it does to the outfeed table is minimal.

If you allow the fence to rest on the table as designed, the other fence issues may be solved.

Read Mike’s comment three times … He is spot on.
And after you sand the bottom of the fence, use a good finishing wax and 0000 steel wool on both pieces’ then Wax the whole table.

Thanks, both Mikes, for the comments. I will try adjusting it to see if it helps. My concern is that the little bumped out tab OhioMike’s picture shows isn’t what’s been causing the problems—it’s the bracket behind that the whole fence rides on, which gets blocked by the table because the bracket that the other bracket slides on isn’t properly aligned. This picture tries to show it:

Like I said, I will try to put it all together again. I take your point about sanding and waxing that tab though—I will definitely do that, and the bottom of the problem bracket as well. Think I may need to throw a washer or two in as a shim on the outfeed side of the bracket holding the ram to try to elevate the fence bracket so it has clearance over the table.

I see it. What if you lower the outfeed table to a lower point and then reset the knives to the the lowered table.

That’s a good idea, I will have to see how much play I have in the depth of the knives.

Have your say...
