« Part 9: Part 3 of 3 - Grizzly 19" Bandsaw Assembly G0514X2B Part 10 of The Coolidge Chronicles series Part 11: Part 3 - Grizzly G0696X 5HP 12" Table Saw »

I continue the inspection, assembly, and dialing in the saw in part 2, here we go.

Looks like I have everything I need, the arbor wrenches are gigantic!

I was in Ace hardware to pick up some 4” clamps and saw these new stainless clamps for only a buck more than the regular hose clamps. I thought they looked cool and splurged $2 extra for them.

$49.95 FAIL! Sometimes when you go cheap you get burned. I have Starrett precision 12” and 24” rulers, they are expensive but they are absolutely straight. I wanted a 36” for setting up this saw, the Starrett was going to be $300 so I cheaped out and purchased this precision ground straight edge from Grizzly instead.

Grizzly says, ”These 36” Bevel Edge Straight Edges are made from hardened steel with satin chrome finish and are precision ground and lapped for straightness and parallelism…Accuracy: 0.001” NOT even close Grizzly. First it doesn’t lay flat, its bowed (bent) over .024 at one end. Second its not straight, its bowed .010. I put this thing across the table saw and thought damn there’s no way the saw table is ground that badly. Matched the straight edge up to my 24” Starrett and confirmed Grizzly’s 36” straight edge is utterly worthless. I have seen Home Depot carpenter squares straighter than this.

The extension wing weighs in at 51 pounds!

Here is the underside of the wing, its substantial with extra beef in the area of the 3 bolts and front/rear edge.

Just as impressive were the size of the bolts, 1.5 inches long and beefy 14mm hex heads. Here they are soaking in some Boeshield. Here in western Washington State its a rain forest, I noticed a few of the fasteners on the Powermatic 15HH planer were getting a bit of surface rust so I have been coating all machine fasteners in Boeshield as I assemble them.

Here she is with the wings attached. I had to shim the right wing about .003 at the bottom and the left wing .006 at the bottom. This brought them up nice and flat when torqued down. The table and wings are absolutely flat front to rear I could find no peaks or valleys straight on front to rear or at angles. I was very impressed with this. Side to side across the main table and extension wings was very good but not perfect like the above. From the right miter gauge slot to the left edge of the left extension wing is dead flat except for one small area which has about a .002 valley. That is quite good. Between the right miter gauge slot and the right edge of the main table (not the right extension wing) there is a valley about .003 deep. The right extension wing is dead flat with the rest of the table though. I’m not going to sweat a .003 valley, its absolutely meaningless. So this is one of the biggest quality points in a table saw, they need to be flat and this one is near perfect good job Grizzly!

In this image you can see clearly the difference in the ground finish of the extension wing, which is quite good, vs the polished main table which is even better! Now its not like polished chrome not even close but I’m pretty happy with it.

Here’s the 1” arbor, its BEEFY and so is the bearing!

Here’s another shot of it.

The 12” blade good lord! Look at the poor 10” blade, it looks like it might cry. lol

4” depth of cut, get some!

Here I’m checking to see if the blade is square to the miter slot.

Here’s the other side but I’m not sure I trust this measurement. They make a precision plate you can bolt to your arbor for dialing this in and I’m probably going to buy one. I need to speak to Forest regarding the blade because I noticed something odd. That said I think this is pretty close to dialed in from the factory and I elected not to attempt to adjust it further.

As I ran the indicator front to rear along the saw blade there was a bow inward of about .006 to .007. I checked the other side of the blade and confirmed it had a outward bow about the same. I removed the blade and checked it with my Starrett 12” ruler, confirmed the blade has a bow in it but is flat out near the teeth. Blade run out doesn’t seem that great either about .005 wobble. Its not the saw that arbor is dead on.

Here’s a shot of the arbor run out, the needle just kind of fluttered right where you see it without moving, your talking maybe .0002 which is to say its probably more accurate than my dial indicator can measure. I was pretty happy with this. That’s a large arbor plate remember must be 3” in diameter so an error would definitely show up here.

Last pic for tonight, here you can see I’m using the planer to hold up the front rail while I install it. The instructions say to first install the front/rear rails then the right extension wing. Its a lot easier to install and dial in both wings without the rails in the way. They suggest installing the rails first so you can quick put a couple bolts in the extension wing while someone else holds up the heavy beast. I also use the planer to hold up the wings so its no big deal to install them without the rails installed.

I’m quite impressed with the rails, after cleaning I gave them a coat of paste waste just because. I’m quite pleased with the saw altogether so far. 6 flat head bolts hold that front rail on, everything lined right up, everything was tapped correctly, zero complaints. So far this saw seems very well designed and manufactured. I have pointed out a lot of warts on their other machines I have assembled recently but they so far have done a great job on this saw.

I should finish up tomorrow and get started on my torsion box mobile outfeed table assuming that blade isn’t totally whacked.

Thanks! That’s a very thorough, in-depth blog of the assembly. Photos are super and helpfull. And, I’m grateful of the critique of the iGaging straight edge and it’s lack of exceptable quality control. Do you suppose a 4” double squre would have similar errors?

Handtooler I can’t speak to the quality of Grizzly’s other measurement tools as I have historically gone with Starrett and Mitutoyo for my measuring tools. I know one thing, every damn time I buy a cheaper measuring tool they suck. lol there’s a clue.

I appreciate you being so forthright. I’ll begin to save a little longer in favor of going more high quality on my measuring and marking tools.

Also, when you checked squareness of the miter slot, did you rotate the blade to make sure you checked the same spot on the blade fore and aft? Doing so should eliminate any blade irregularities from the equation.

Yes but that blade was whack…see my next blog post on the saw in about 15 minutes I have good news on this.

Have your say...
