This is 100% one of those times you would ask why you put up with something so long... 27 years in this case. Package arrived unbelievably quick and great shape in...2 days I think...and I had it on in about 2 hours. Thanks Toolbarn and UPS! My saw is a 1994 Craftsman 113 contractor with the cast web wings. As soon as I took the T3 out of the box, I figure I would rather drill my saw and save the fence original since it would not go with the saw if that ever happened. I don't remember what I paid for the saw but this fence is pretty nice. I also don't feel I could get a better current new saw under $700 VS the 113 and this Delta so it's money well spent in my book. Lots of videos out and forums detail it already but here's my take... Use favorite method of transferring your blade centerline to front of table. Check it. Check it again. Do this for everything. Use the template for the rails. As typical, getting things lined up and missing webs on the cast underside was pretty futile, so I ended up just transferring the OEM Craftsman holes over to the Delta angles. Given it's just angle iron it wouldn't be the end of the world, but if you've got the tools and the skills - which you do since you have a saw and bought a nice fence - it'll be all good. Use the template. Clamping and "dry" fit are always good ideas especially on this type of operation. YMMV but my front angle bar ended up about 0.25" proud on the left cut side which I think is generally the spot. The actual guide tube is longer so is not noticable. The rear I had to shift slightly to avoid a new hole thru an existing one. You could mill a slot if you wanted, but I went 0.5" or so for better fitment to the right cut side. This did not affect the published cut and support of the rear rail slider. They give you a little wiggle room. Do note the amount of adjustment you have on the "reticles" - this is your maximum wiggle room. All said and done I drilled 6 holes in the Delta angles, 3 on the front need to be countersunk, and I chased the 6 Craftsman Tabletop thru holes up one size. Lots of extra hardware in the package and oh yeah did I mention the provided steel template works well. I still need to mount the safety switch, but I also need to build the cabinet to mount the switch on. And new wings. The struggle is real. Very pleased with purchase and Toolbarn.
