Forrest Dado King on my Hammer B3 

Hi Coffee, I don't think you can get a new arbor as this is specified when the machine is ordered. If you can get Felder to sell you one, it would be a major undertaking to replace it.

@@CutitwithaHammer , thank you for your response. You valued advise id duly noted.

Usually on a dado stack, the outside blades have two different types of teeth: flattop and angled. The angled tooth is to reduce chipout when the stack exits the board or panel. For that to be effective, those teeth have to be just a little bit longer than the flattop teeth. In most cases, only you will see this (most people won't). Especially in larger projects. In small projects, it may be more apparent. If you want to eliminate the bat wings, you can: use a blade with all flattop teeth and make multiple cuts; use a router; or clean up after the dado stack with a router plane. Some manufacturers also create Box Joint stacks which don't have angled teeth. I also get bat wings on my groover heads for my shaper.

@@CutitwithaHammer the Felder dado blade is a good option. No batwings

Hi! The arbor on my B3 is what the factory ships. I wasn't given a choice at the time of my order. It's a 30mm with two locking posts. Once I found some blade manufactures, it hasn't been a problem finding something that works. For special blades, such as my dado stack, it does up the price.

I'll have to mount it up to check. I think it's about 3/4". I'll get back to you on that.

Sorry for taking so long. You can get about 0.8" of depth.

When you order from Forrest, there are a lot of different arbor choices. For a Felder machine, it's a "30mm bore with 2 pinholes". The price is $90 more than a 5/8" bore.

I have some old 10" blades that I was thinking of taking to a machine shop to see if I can get them re-bored.

@@CutitwithaHammer thanks. i'm looking at a felder slider, considering my dado options aside from the felder version

@@dblehar You might be able to go with the 8" on the Felder machine. You could ask on the felderownersgroup at groups.io

@@dblehar Have you completely ruled out the Felder dado? I went with their dado after having very positive results on my A26 with their silent power cutter. The ability to rotate a dull or nicked piece of carbide is huge and their dado set uses the same setup.

I can get 23/32" worth. That makes use of 3 of the 1/8" chippers and there's an 1/8" chipper that has a slightly thinner body (I hadn't noticed it before). That would be pushing the safety limits.

@@CutitwithaHammer That 1/8" chipper with the thinner body is most likely a 1/32" chipper. The set comes with 4x 1/8", 1x 1/16", and 1x 1/32" chippers, allowing you to make dados such as 23/32" wide. I have the same set for my K3.

@@stevewurster I apparently didn't read the literature for the Dado King set. I'm terrible about reading such things. I should do better. I did go out and measure the bodies of each of the chipper blades. There are four 1/8", one 1/16", and one 3/32", which matches up with the Forrest documentation. Thanks for pointing that out. I'm curious about how the 1/32" chipper works for you. That's pretty thin. But if it's sandwiched in between stiffer chippers or outer blades, then I suppose it's going to work well. How old is your set?

@@CutitwithaHammer I bought my set about a year ago. I don't use it that often, mostly because it is time consuming to install it and remove it. I don't think I've used the 1/32" chipper yet, but I would assume it works well when sandwiched around other blades. I definitely used a chipper that small on a different brand dado set back before I had a slider, and that worked fine then.
