Did you know that there’s even a patent on a Box Joint Jig? I’ve always wondered why there we’re no commercial ones for sale. All anybody does is sell their plans, on how to make them.. Now I know why.
There must be hundreds of different ones out there. Even Norm has his plans, and he sells his..:) Dam good thing we can shop-make these things. I’ve made one that’s awesome… I’ll be posting it soon…:)
Better than Norm’s even..lol
