Looking for Infinity Cutting Tools Lock Miter Master Jig

I have the one I bought from Rich and it's not for sale. It's a cool precision feeling way overpriced tool. I think I used it once. You don't need it. It does work, but so does the plastic block that comes with it seen below in the middle picture, and Rich's method works great without spending any money. I've used all 3. Same results.

So, as Rich said, save your money and follow his method.

What you need is a lift that will let you micro-adjust the bit height and some well-made jigs to run the stock past the bit. Even though Rich will probably disagree with me, any method you use will not be right to start with. They all require about the same amount of micro-adjustment. But when they are perfect, it's a beautiful nearly invisible thing. Then you make a hardwood template when it's perfect and use that without measuring if you don't have the plastic block.



Here are my results.

Thanks guys. I think the Infinity web site was down when I looked the other day. I m not sure if this bit is worth the trouble, I ll have to think about it.

Once you learn the technique it is absolutely worth it, especially if you're making small jewelry box drawers and boxes. They really look professionally done. This was my first attempt after seeing a jewelry box in a store that used them. Not a good joint for larger projects IMO.

Looks as if I have the dissenting opinion here. I like the infinity jigs.

At first blush it might seem pricey, but have you priced machine shop work lately ? Ask to have a piece of aluminum precision ground and marked and let us know the quote you get. Then go price out anodizing. Then tell me how much a couple of small ,thin magnets cost.

As far as usefulness, well…............. I just disagree with Rich. I find his $60 wixey gizmo worthless, but that's what makes America great. Lots o ways to skin a cat. A digital setup gauge is no more or less useful to achieve the tolerance you need for a perfect lock miter joint. It's simply a different kind of useful. Both methods will get you darn close off the bat. You'll still need to micro adjust to get it perfect whichever method you use.

Thing is, the jig will get you roughed in a lot faster. Like the digital measure, it can be used for practically any bit and material thickness. Those UHMW blocks (or your DIY ones) are only useful for your bit and the same thickness material. And we all know how consistent wood thickness is. And if I want to use 1/2" or 5/4 - then it's a no go or I need to make different blocks.

Oh, and I forgot to say that the jig can be used to setup offset miters for things like adding a roundover afterwards or joining two boards of different thicknesses. That ain't as easy with the digi gauge.
