My Instructables on how to improve a crappy table saw generated quite a few comments that it did not show the actual build up process especially the fence mechanism, so as promised I am building the fence again because i what to change the fence stop.
I'm using another saw so before building the fence I need to make sure of the blade alignment, and this is what I'm showing in this short demo.
First step is to make sure that the blade travel stops at 90 and 45 degrees. if its out of true you will need to make adjustments in this case its a matter of turning the saw over and making the adjustments.please check your saw manual on blade alignment.
Step 1: Blade Adjustment Posisions
3 snapshots of the adjustment bolts and locknut This is a cheap entry level contractors saw sold under different brand names
Step 2: Wedges
You need some small wedges for the next step, Please check my making wedges safely on the bandsaw Instrutable
Step 3: Setting Up a Steel Rule in the Mitre Channel
Wedge a steel rule in the mitre channel making sure it's at 90 degrees
Step 4: Measuring Blade Alignment to Mitre Channel
Mark the blade in one position then rotate blade so its on the table make your measurements make sure to write them down, if the blade is toeing in or out make adjustments until you get the same reading front and back.I've used a vernier gauge
Step 5: Straight Edge
You can also use a straight edge laying along side the blade and measure to the steel rule
Step 6: Ready to Build the Fence
now I'm sure that everything is correct Iv'e wedged my straight edge in the mitre channel and clamped a square to it and this is what I'm building the fence against and that coming up next.
