Craftsman Digital Miter Gauge, 320.29939.
Mario and Tia Salazar invented and hold the patent on this precision digital miter gauge. At the 2006 International Woodworking Machine & Furniture Supply Fair, Salazar’s digital instrument was being displayed. The miter gauge caught the eye of a supplier of the Sears and Craftsman line of tools. They entered into a licensing and royalty agreement together.
This miter gauge has been reviewed with praise from Woodworkers' Journal, Wood magazine, American Woodworker and Popular Mechanics. Popular Mechanics gave the digital miter gauge an Editor's Choice Award.
I think this miter gauge, even though praised, is under-rated. Sad, but as far as I know, the inventor's licensing upfront money and 8% royalties have yet to recoup their initial investment.
I love it. More accurate than I could ever want. Accurate to 0.1 degree, which I tend to get near and leave at that as acceptable. I don't make parts for rockets, but I do want accuracy to be there. It accepts 80/20 styled 10 series aluminum extrusions without any modifications or adapters. It came with a 15-1/4" aluminum 1020 fence. I usually use it with a 1020 36" or 48" fence. The miter bar is adjustable to snug into miter slots. It zeroes easily.
It comes with an accessory extrusion that makes it double as an accurate digital blade bevel gauge. This requires taking off the blade insert to do this. i find the Wixey or Cen-Tech Digital Angle Gauge easier and faster to use than this gauge for that purpose as those don't require you to remove the blade insert. (Note on the Cen-Tech- Glue the magnets to the base of the gauge before using. It's low cost must have been from cutting back on things like glue-cost. Otherwise a great gauge.)
I got this gauge at $30 from a local Sears store who was clearing their shelves and had it on closeout. I got more value in that purchase than I had imagined. If I had the chance to buy another (even used) at that price, I would jump on it without thinking twice and consider myself blessed!!! Even at it's regular price... It's a good deal.
Delta 36-946 Heavy Duty Precision Miter Gauge.
This is a rebranded Osborne along the lines of the Osborne EB-3 and Dewalt DW7470. It is not as polished as the Osborne EB-3, but has a few pluses over the Dewalt DW7470. All three use the same tri-braced miter mechanism and basic Osborne fence extrusion. Regularly, the standard retail pricing is that same for all three(!?!), but they have differences.
Osborne Miter gauge owner's here had good things to say about their miter gauges and are very loyal to this product. The Osborne EB-3 is a finished quality compared to it's 2 rebranded products (Delta and Dewalt). All the bells and whistles. The EB-2 includes a stuck-on measuring tape scale, a fence that extends from 24 to 31", a stick on sand paper face, a sliding adjustable stop, a tall user handle, A shinny adjustable miter bar.
The Dewalt DW7470 has the basic 24" fence extrusion without the fence extension. It uses the same black miter bar as the Delta (described below). There is no measuring scale for the fence. No sand paper. It has a short user handle.
The Delta 36-946 is that same as the Dewalt plus a quick release, heavy duty material hold-down clamp. Like the Dewalt, it has has a miter bar that includes a boss for mounting that hold-down clamp.
