What do isolation pads and trunnion adjustment have in common?

Who knows?
Got the table saw fully running this weekend. Had to adjust the trunnions, build a zero clearance insert and adjust the fence. Here's my low-buck approach to adjusting a table saw for accurate cuts.
If this process is new to you, you should adjust a table saw when it's new, new to you, been dropped, been rebuilt or anytime the saw sees a large shock.
Most saws have the blade assembly hanging from the top. Cabinet saws will be independently mounted, and you will adjust the table rather than the blade. The saw swivels from two cast half circles on each end that have been machined to act as guides. Three bolts hold the trunnions to the top.
Typically you want to align the blade with the miter slots that are machined into the tabletop. This is independent of the fence/blade alignment, which is a whole other topic. They do make some tools to help you adjust the trunnions and hold them in place while you tighten the bolts, but.... not worth it to me.
You can get away with just a go/no-go gauge, feeler gauges, anything really, but I like to use the dial indicator because it's great for this kind of application.
First step is to unplug the saw followed by raising the blade as far as you can.
Mark one tooth with a marker.
Go ahead and make the little jig to hold your indicator. I used 1/8" steel because the mighty-mag is, well, magnetic. You want a tight fit in the slot, use shims to shore it up if need be.
Put the indicator on the side of a carbide tooth. I don't use the blade because the coating can throw off your measurements, where the blades are precision ground. Zero the indicator. I like to start with the front trunnion bolts fairly snug.
Rotate the saw back and slide the jig back until you can reference the same tooth.
I found that I had to apply a bit of pressure on the trunnion while I tightened the bolts to ensure it stayed true. One bolt will walk the trunnion one way, the other bolt the other. Go back and forth to stay on the mark.
Go back to the front, rotating the saw back around, and ensure the front hasn't moved and that you are still perfect. Took about 10 minutes and I was within 0.0005 per the indicator. Pretty accurate for a 60 year old table saw.
Next thing to do, for which I regretfully don't have pics, is to set up the positive 90 degree stops. I used a digital angle gauge. Got that to 89.9 degrees, close enough for me. I set the pointer arrows to use a a quick reference, but you can't beat the magnetic angle gauges for about 10 bucks.
Last, but not least, use the same jig to set your fence to the miter slot. Some people prefer a 1 degree kickout at the rear to presumably help with kickback, but I'm not sure there is an advantage. A well prepared saw with a good blade and good technique will yield great (and safe) results.
Side note: can't say enough about the Freud glue line rip blade. Get the real one, made in Italy. Man it cuts well, even for my 1 hp saw.
On to the isolation pads, aka, hockey puck feet. Being a native Texan, this is the first time I've seen a hockey puck in person, quite dense, and at a buck, not a bad pad for a compressor.
Get some bolts and washers and nuts, 1/2" for this application.
Find and mark the centers.
Finding centers, the easy way.
If you've got a lathe, well, you ****. Skip this step!
1 3/8" forstner bit for the washers. I set the depth stop so that the washer/bolt head would be recessed about 1/8".
Rubber cuts like butter. Didn't freeze it, just room temperature. Used 350 RPM, I believe.
Don't ask me how that one got off....
Follow that with a 1/2" hole and voila:
Use the wife to place the feet while you tilt the beast and...
Cheap and easy. For those that are curious, it did not help with noise reduction, but I did maybe feel less vibrations in the floor next to it. I won't be mounting this to the floor, and yes, I accept the risk. Didn't have any problems getting the bolts snug with the head slipping, didn't see any need to get it super tight either. This was a cheap, 20 minute project. I might consider a steel pad on top of the puck to prevent the foot from cutting into it. At a buck apiece... it will be hard to want to add to them.
Thanks for reading!
