Topic tags/keywords: dado delta 36-441

I have a Delta 36-441 Contractor’s Saw. It’s about 15 years old. It’s been a great saw – zero complaints – and it works just fine. The entire saw is as it arrived from the Delta dealer – no upgrades or replacement parts. Now, I’d like to use a dado set with it.

I started my dado research by removing the table insert to examine the arbor. With my normal general purpose blade installed, there is roughly 5/8” (maybe more) of thread from the end of the arbor to the outermost edge of the flange (itself is roughly 1/4”). So there is roughly 7/8” (5/8” + 1/4”) from the end of the arbor to the outermost edge of the blade.

This saw will likely be used to cut dados for shelves and cabinets built from 3/4” Baltic birch plywood and up to 1” thick hardwoods. I’ll also be cutting a bunch of dadoes for cross lap joints in pine, maybe treated lumber. I understand multiple passes will likely be necessary for wide and/or deep dadoes.

1) Can I use a dado set with this saw? Or is this not recommended?
2) Are replacement arbor flanges a good idea? I’ve read a few posts where thinner flanges are used.
3) Given the arbor length and horsepower (1-1/2 hp, 115v), what are reasonable single pass dadoes (width and depth) in baltic birch plywood and oak?

I’ve used dadoes in the past but they’ve always been setup on someone else’s saw and I just make my cuts. That said, any additional guidance is appreciated.

Remove the blade guard and such, you got to drop the arbor flange, it will work just fine

That saw will handle up to a 13/16” dado stack as well as moulding cutterhead. As mentioned, you will have to remove the blade guard and splitter, and use a dado insert plate instead of the standard one. When using the dado stack, you don’t use the outboard flange washer. From the manual:

NOTE: THE OUTSIDE ARBOR FLANGE CAN NOT BE USED WITH THE DADO HEAD SET, TIGHTEN THE ARBOR NUT AGAINST THE DADO HEAD SET BODY.

As for how much bite you can take per pass… you will have to experiment with that yourself.

Cheers,
Brad

I have the 36-474 (same basic machine). As already mentioned you’ll need a different blade insert plate and you’ll set aside the outer flange (i.e. the arbor nut goes directly against the outside blade). Been using mine with a Delta dado set for years all the way up to 3/4” width and depths over 2 inches. No problem. Figure the dado set is doing the bulk of the work, not the saw.

I have similar saw, older, but same measurements, i have a dado that goes to 13/16. The nut is right on the edge but still fine. I made my own plate out of plywood, just raising the blade through at 13/16, works great since i mostly use 3/4.

Have your say...
