I was wondering if anyone has tried the Delta Dado Blade set. Delta was kind enough to give me a New Dado Blade set. I went to use them the other day, and the chippers would not fit on my arbor.
I have the new version of the Unisaw with a 5/8″ arbor, the blade set is also 5/8th. I was able to get the inside blade and 2 shims on with no problem. But the chippers will not fit on the arbor. The last thing I want to do is force them on and end up damaging my arbor.
The blades were given to me as a kind of peace offering for problems I had when I first got my saw. Up till now I have been using my Forrest dado set, which needs to be sent in to be sharpened. That will teach me a lesson about procrastionating (sp?) again.

Dado blades need to have tight tolerances, but not to the point they need to be hammered on ;-)
I have a Delta dado set that works great. Snug slip-on fit to the arbor. The caveat, however, is my set dates to the '50s, when good machinists made a buck sixty-five, or so, an hour. ;-)
Sounds like you may need to carefully ream your chippers a bit to get a good fit. A hardwood dowel with a very slight taper, wrapped with 220 wet/dry might do the trick, working from both sides of the chipper blade.
Thats kind of what Iwas thinking of doing, just making the hole a hair larger. Delta is sending me a new blade set.

Not sure which Delta set you're referring to. AFAIK, the Delta 35-7670 (8" 24T cutters/4T chippers) is the same as the DeWalt DW7670 set....pretty nice set on sale in the $90-$100 range, and actually resembles the Forrest set a bit. Delta also sold a cheaper set with 24T cutters and 2T chippers..Delta 36-515....possibly others.
The DW7670 set I had fit the arbor pretty well, but I have had other sets that were "uncomfortably snug"...I hit them very lightly with a fine file, then some fine sandpaper, which helped quite a bit. The trick is to be delicate or you'll end up going too far and have a sloppy fit.
I second what Scott said. I have the DeWalt set and am quite pleased with it's performance (and low cost). The fit on the arbor is precise. They go on fine if I take care - they will bind on the arbor if the blade is tilted too much. And the outer blades and chippers seem to have the same bore size.

Well I took a deep socket and wrapped it with 220 and took my time till I had a nice snug fit. They made a nice cut, I hope they hold a edge as well as my Forrest set.
Now to see if they will come off the arbor?

"...I hope they hold a edge as well as my Forrest set."....and I wish for world peace, and an end to world hunger. :D I'd be really surprised if that was the case, but hey, ya never know....keep it clean.
I have a set of the 8" Delta dado blades from around 1980 or so. They work very well with no chipout on any cross cut grain I have ever done. The chipper bore can be checked with a .625 plug. I imagine the bore should be .6255 pr maybe .626.You can get a machine shop or saw sharpening service to check and correct the bore. I believe Forrest and Ridge carbide do this for a fee.

Before you try anything drastic, give them a soak and scrub with lacquer thinner. Often saw blades have a clear coating from the factory to prevent rust during shipping. My Frued Super dado had the same problem and as soon as I cleaned the clear coating off they fit much better.
Good luck

A light sanding did the trick, I still have to try getting them off the arbor. I'll just have to take my time and count to ten when I get too frustrated.
