I’d like one that works with all the common dimensions of the current stock of plys (which is many, I know.) Anyone have any suggestions on which brand they feel is the best and/or best bargan? It will be running on my baby: 3HP, single phase, 10” Delta Unisaw – 5/8” arbor.
(just like this one: http://www.deltaportercable.com/Products/ProductDetail.aspx?ProductID=21103)
Thanks!

I own the Freud dial-a-matic. It is probably the best at finding those odd widths without the use of shims. It is very easy to click into the exact width you want. The blade comes with a chart that tells you which cutters to use and how many clicks to find any with in 1/256”.

It is expensive but in addition to the dial-a-matic feature you are getting first class quality in all aspects of this dado.

I saved a little money by getting the 6” version, but in my work that is big enough.

I think the Forrest Dado head is the best one out there. They have a special size chipper blade that you use for under size plywood. There is no need for shims. Not the cheapest by any means but they seem to last longer between sharpenings than some of the others and they last longer. So in the long run they might be cheaper. Great saw you have there! How is it working out for you. I thought about waiting for them to come out but wanted to get a new saw for the shop and get started building stuff. I bought a Powermatic 2000 but always wonder if I shuold of waited for the Delta.

God Bless

Rich and Tom: Thanks for the advice. I’ll be researching both of these blades in the near term!

Tom, It is an awesome machine. The only complaint I have about it is I CAN’T keep it busy enough! It’s a great thing to be able to set the fence and the bevel to the numbers displayed on the fence’s ruler and bevel’s dial and KNOW you’ll get an EXACT cut without having to double check with the folding rule. Dust collection features on it are top notch, too. One more big plus is the wide throat… wicked easy to swap out a blade.

I am very happy with my Freud stacked Dado set. It uses shims to fine tune to virtually any size; however, most common sizes can be achieved with just the chippers. Tweaking with shims can be just as fast as adjusting a dial (at least for me) and you get perfectly flat bottoms.

Roger that … and I am a guy that usually prefers a shapely bottom but this is one place where the flat bottom is a good thing

Another vote for the Frued SD508, does everything I’ve asked of it in both a 1.75 Craftsman TS and my new PM2000. The SD508 with shims and the chart is very easy to set to a specific width, and yes, the dado bottoms are flat. Just a tiny track at the edges of the dado, but could be I’m setting something wrong.

Must admit I’ve only used two dados, the Frued and an old old craftsman, so I’m sure others with lots of experience can give better advice.

Rich, How deep a dado can you make with a 6” blade on a 10” table saw?

Like Rich, I have the Freud Dial-a-matic. The way you can actually dial in the needed width is fantastic. It also provides a good clean flat bottom. pk

Another vote for the Freud SD508 – excellent cut quality in every material. Assuming the dial-a-width Freud dado has similar cutters, the more-convenient width adjustment would push me in that direction (it just felt like too much money when I bought my dado set a few years ago).

I have the Oshlun SDS-0630 6” set for my Ryobi saw and it works awesome, flat bottomed dadoes every time, plenty of adjustability, etc…

Oshlun makes an 8” stack as well, I think it was Wood Magazine that did a write up on it last month or so… Inexpensive stack that keeps up with the big boys…
