I appreciate you not editing out the error. It's comforting to see even pros make the same mistake that I have on countless occasions while trying my hardest to avoid it. Thanks for keeping woodworking "real"!

I can't wait to see the finished product.

Can't wait too see harder Bit !

I have seen a lot of your videos where you push bushings over pattern cutting. Here are a few other reasons why bushings are state of the art: 1) If you think of probably the single most expensive and revered jig out there, it might be the Leigh Dovetail Jig. Or at the cheap end you have the kind of dovetail Jig Porter Cable now sells. Both use Bushings, there is one that uses pattern bits, but it is less versatile. Keller? Forget the name... 2) Pattern bits need to have a sturdy shank, like any bit designed to take heavy cuts. That means that 1/2" shank to me. So you are looking at maybe a 1" cutter that is not spiral upcut, all carbide. So that means a lot more sawdust to expensively extract, more wasted wood, and a lot more effort. If you wanted to trim to the line with the pattern bit, you could eliminate a lot of these problems, and the accidents Ron is always talking about by doing an initial pass with a bushing, and doing only the final clean-up cut, at full depth, with the bearing having good bearing on the pattern. Drop the router in place, then start it up without the bit initially in contact with the wood. 3) There is a lot of talk about how to make patterns for bushings to cut to final dimensions accurately. I made the patterns for the Smart Bench and all was well, but now I am stuck with some patterns I will probably never use again... The only one that is particularly troublesome (big) is the one for the saw horses, and they are so great that maybe I will use the pattern again. But lets be clear. The difference is only 1/16 of an inch. There are a few places where that might matter, largely the interlock on the Smart Shelf (which isn't even used on the units that use a Smart Kart, though it is one of my favourite pieces). And there are only a few places where the pattern would have to be altered even if you did decide to go ahead and use the pattern in a sawhorse. Ron did use this very strategy on the original miter saw project. 5 of the sawhorse parts are cut with a pattern and the 6th is the pattern. I won't go into why this works in some cases, and not in others. 4) One approach that works is to cut your pattern full size, then run a bushing to cut it out with a spiral upcut. Then run a second pass with a pattern bit at full depth, just to trim it to flush. You can also use the less expensive 1/2" trim bit, but from the other side. That way, you do not waste material on patterns, or have to store them. You don't even need to flush the whole sawhorse. Just the contact points, if you prefer. Those would be the top surface, the feet, and the interface for the shelf if you are building one. You can also flush the top surfaces of the material support arms. 5) I have several plunge routers, but the one I had the bushings for at the time I made my Smart Bench, was the fixed base Bosch. I had no problem doing all the pattern routing with the fixed base router, and a 1/4 upcut, and a 3/8" bushing. So don't be put off if you don't have a plunge router. Negative: One problem with the busing pattern method is you have to buy bushings for your routers. They are cheap, but I have a lot of routers and it does add up, and for some routers they are hard to find. The bits are a lot cheaper, though

Very useful, thank you.

I got a set of UJK metric template bushings and a few metric sizes of spiral downcut bits, it makes it much easier than trying to juggle fractions. I wish more companies would make metric bits!

I have had the same problem with pattern bits. I too am switching to bushings.

I guess Im a bit confused. You made a video proving your theory, that a bushing works better, when you already knew that, and have mentioned it many times in other videos? You made it seem like today was different, and you were expecting a different outcome with the pattern bit. What am I missing?
