Project Information

I recently bought a 1" travel indicator and a mighty mag to try and get my saw blade perfectly aligned with the miter slot on my Delta contractor saw. After seeing the Forrest Saw Blade display at the Houston Woodworking Show a few weeks ago, and seeing how well they had their Delta contractor saw aligned, and the scratch free cuts they were producing I have to tell you, I was jealous!

I've always had good results out of my Forrest WW2 blade, but after checking the run out on the blade, and finding 0.10" run out, I thought I could get it a bit closer with a travel indicator. Well after a couple hours of trial , error, and adjustments both with and without the belt on, I got it to 0.002". I discovered that my contractor saw experiences a pull to the left of .002 with the belt on resulting in a 0.004 total front to back. So I had to adjust it to .002 on the other side of 0.00 to compensate for the play in the bearing. Now the blade is 0.001 on each side of 0.00 front to back.

Once I had it adjusted out, and my blade at 90 degrees, I ripped and cross cut these pieces of cherry with no scratch marks! I am happy, and no longer jealous!

My indicator came in a styrofoam case, and the Mighty Mag came in a cardboard package. Being a woodworker, and recognizing the value of my new acquisitions, I decided to celebrate my achievement by building this case to protect my new investments! All the boring was done on my new 17" Jet Woodworking drill press, with various forstener bits, and hand chiseling, and shaping on the case. The lid has a hand carved relief for the crystal on the indicator. Finished in 3 coats gloss polyurethane, with felt feet on the bottom. Hope you guys like it!

That's the way to take care of new equipment. The box is great.

Those mitered corners are barely noticeable , Matt ! LMAO …Great job and an awesome idea for your new toys : ) I purchased a gauge set like yours a couple weeks ago and now you've inspired me to put it to use . Thanks for posting this , Matt , and have a great day : )

Matt, What is the Mighty Mag, a mount for the indicator? What do you do with the dial indicator, find a "0", then measure how far out it goes with the plunger?

Box looks great. Should be bullet proof protection for the instruments.

Matt, this is a really nice box. You could have simply made it out of mdf since it is a piece for the shop but I have come to appreciate the extra effort that goes into producing for the shop that is not only functional but looks good as well.

You did a good job on aligning your saw too by the way. It can be a challenge but producing burn free cuts in cherry is well worth the effort.

Here is a picture of some cherry rails and stiles that I cut on the Craftsman saw I used to have. It took me about 15 minutes to get the saw aligned and tuned before making the cuts. So I can well appreciate the effort you put into getting yours tuned.

Great project, Matt.

I've got kind of the same question as Survivor, I assume the Mighty Mag does basically the same thing as the TS-Aligner (Jr?). I'd be interested to hear how it compares from anyone who knows.

Scott,

Yeah, it's about the same, only I spent $57.00 on the two components. You could get it cheaper if you go with a Chinese mag, and indicator.

I got mine on sale at Harbor Freight..magnetic base and dial indicator . I couldn't justify spending big bucks on a seldom used item to get the same results. : )

just a little trick i use is to loosen up the blade and put some metal shim stock on one side of the blade and tighten it back up, its simple after you figure out your runout to do the math to see how much shim you have to add, and as long as you tighten it up nice you wont have to worry about it coming loose but i wouldnt try more than .010 shim or so. being a machinist i do this with a horizontal milling machine climb milling steel all the time and it has never came loose, also if you dont have the right thickness blade you can do this to make the blade wobble to get the right width you need. and i work at starretts so i get free indicators and bases :)

great looking box and you will find many great uses for that indicator
