⚒️ A couple of tools I really like:
Digital bevel gauge: amzn.to/3ie6L0o
High-vis tape measure: amzn.to/3ifHzXn
I REALLY like these little rulers: amzn.to/3ggJV7C
These mechanical pencils are pretty sweet too: amzn.to/3pLvATx

Good tip. I suspect that vibration is also reduced adding to a cleaner cut. Loved the board flip at the end.
Can't say I've seen this anywhere else. A dead easy and even REVERSIBLE hack to get better cuts. Nioce.
I feel like I read an obscure forum post from the early days of the internet where someone had the same problem but fixed it with JB weld 😳
@@Craftswright JB weld??? Whoa, thanks for giving a less extreme (and undoable) option.
This video was very helpful. I may do this in the future but mostly it helped me learn that my dado set wasn’t defective!
Pumped to see that you’re uploading again!! Keep up the work! I love your energy
Thank you! Means a lot to me to hear that
Never would have thought of that thanks.
Glad I could help!
I thought you was full of it until I just tried now we will see if it stays the entire project thanks for the video
Glad to see you back my brother
Good to be back!
Welcome back! Missed watching your videos. Putting together a set of the sawhorses really soon!
Love to hear it Owen
Great!!!
I knew a few woodworkers who came across this issue some years back; they used jb weld and sanded it smooth with a strip of flexible sandpaper while the saw was running (kind of like how you polish something on a lathe). No blade, obviously.
Great to see you making videos again btw!
Right! I saw the JB weld solution too...hated the idea of something so permanent so I thought I'd give the CA glue a shot. Shocked it worked so well haha
@@Craftswright That's fair. I probably wouldn't have an issue with the jb weld fix since it doesn't harm anything, but these days I use my track saw mostly. 👍
Nice idea, I won't need to replace the o-rings I've been using all this time, lol.
Well engineered! Good job
Thanks so much. For the longest time I thought I had a defective dado set. The chippers were either had a defective teeth or a not perfectly rounded arbor hole. One thing I noticed is that it always takes place in the first chipper which led me to your video. Mystery solved. Thanks so much.
I bought a Freud SBOX8: 8" Box Joint Cutter Set sometime back and it probably had given me the step in the cut on the left side of about .003 so I was going to make a jewelry box and use my new Incra to make it and noticed this step in the cut. I saw your youtube video and put the super glue on my Sears contractor table saw arbor shaft but instead of shaving off the excess CA I just forced the arbor nut to shove the two blades over and tested it and it cut perfectly.
Glad to see you posting again. Really enjoyed your vids.
Glad to hear it! More to come hopefully haha
Gracias por compartir tanta información y conocimientos maestro, un saludo cordial y por supuesto un gran like desde Narón (Galicia) 👍🤓
Gracias amigo!
Hope your ok out there, been a long while since your last video.
Pretty curious indeed, dude! Great fix for it! 😃
Stay safe there with your family! 🖖😊
Cheers MC!
Hope you're well, big guy.
Dude! Fantastic! Thank You.
You bet!
Make more videos please
Great video! Thank you.
But there was no new vids for a while?
Hope all is good?! ❤
🎉
That works great for a small dado but It doesn’t look like it would work if you wanted a 3/4” dado. You would need to put ca glue on on quite a few threads, making it difficult for a perfect center, even if can just pick out spots. It also seems too tedious for larger dados. I could be wrong so please let me know. Thanks
Just found your channel. Noticed nothing new for a while. Hope you’re okay.
Where did you go, man? Planning any new videos?
My dado stack came with spacers and the instructions said to always use a spacer after the blade before any chipper inserts. Never knew why it said to do that, but I guess this is why. No glue needed, just follow the instructions. 🤷♂
Bahaha...even tried smudging with sage....
How about a wider washer??
Hmm I’m cautious that would just shift the problem over 🤔
@@Craftswright what keeps the other blades from sagging on the threaded section? Also you could wrap the small section with a piece of tape or equivalent.
Good question! The “peaks” of the other threads are much closer together, not allowing a blade to sink down into the “valleys” between. But that very first valley? Oh brother it’s a big’un!
Mine seems to cut the edges deeper than the middle.
Why is the gap there in the first place? It doesn't look like wear, it looks machined, but I can think of no reason to machine something that deep, after the shoulder and before starting to cut the threads. Other than to intentionally mess up a dado stack? Only partially joking, since they're illegal in some countries as an unsafe table saw accessory?
Oh, and by the way, great hack! AND great info! I was just about to use mine on an old Craftsman contractor saw for the first time, so I'll know to look for this.
If it is turned on a manual lathe... I often see machinists on CZcams cut a ring into the base of a threaded section because it takes multiple cuts to fully cut a thread, and when they disengage the movement for the thread cutting tool, the part keeps spinning, with the tip of the tool right in that groove.
@@Kineth1 Oh, like a relief groove to give the cutter someplace to not be bottomed out, not still engaged with the piece, so that it's not touching on that end of the shallower thread cut? Yeah, that does make sense. Probably is the reason. Forget my conspiracy theory about messing up dado stacks.... 😎
@@billparrish4385 that's exactly what it is! It indicates that these arbors are single point threaded on a lathe. You have to provide clearance for the tool. Plus, that rounded groove prevents stress risers at the point where the shoulder meets the thread. Blondihacks has excellent videos on single point threading if you want to see how it works in more detail! Plus her videos are awesome. In general, it's a good practice to look for a mechanistic explanation for something like this before assuming a malignant conspiracy. I think if more people practice that skill the world would be better.
@@evanbarnes9984 The world would indeed be a better place if that practice were followed. And, at the risk of loading yet another life lesson into that 1/16th inch groove, my hypothesis came about from an ignorance of the finer points of machining threads into a shaft, plus a factoid I'd heard about some places outlawing stacked blades as being too dangerous. That difference in 'knowledge sets' between people can often be found at the bottom of many conspiracy theories. We live in such a robust information age, we often (somewhat arrogantly) think we already have a pretty good handle on most relevant facts, and then are surprised when we learn about a relief cut aiding in machining threads, and realize those hoofbeats we heard were in fact just a horse, and not a zebra at all. Sometimes a little humility in recognition of everything we don't know can be useful. 😎
Cheers, and thanks for your observation!
Tried everything? I only saw incense. You needed to go Old Testament: sacrificing perfect bulls, sheep, chickens, the odd child here and there, etc. And, of course, there is the ultimate fix of throwing away the table saw and make your own wooden dado plane.
Glad that you are able to make videos again because your dad is doing well.

Go Ducks.
Stupid but it works? It aint stupidz.
Amen haha
Cody, I just posted something of a response to this video for my subscribers. My channel is dedicated to the use of Shopsmith woodworking tools, and I had someone ask me if this hack was necessary for the tools that we use. Check it out, and great solution for your problem. Scott
Very cool, is that common with the Shopsmiths?
@@Craftswright Yes, the headstock has an unthreaded 5/8” shaft and you mount various arbors to that shaft.
Get a better saw.
