Default Best StewMac video ever

In the past I have been alternately dismissive/complimentary in varying degrees about StewMac, but I have to say that in this video Dan absolutely nails it. This is genius.

Of course, I fully realise that somebody is bound to respond saying ... "Mehhh ... been doing it this way for years" ... but as far as I am concerned this is the first time in a long time I have seen a genuinely new and valid woodworking machining technique.

I can see further applications as well ... if you wanted to create a slight concavity in the fretboard substrate prior to gluing up, using a surfacer, this would be perfect.

Doolin had the idea at least a decade ago, if not longer:

I've done the same thing with a router, both on a router table, and handheld with a jig, probably well before I saw Doolin's site.

Obviously, a number of clever people. Kudos to them all.

As an aside, I'd never use that type of truss rod, and have no need to create the curved slot. Still clever, though. I first saw a repairman I worked for do that with a router in 1979.

Table saws scare me enough to never own one but I cannot imagine getting my fingers that close

I imagine you could build a carrier for a router just as easily.

I have no need for that style truss rod either but it's a clever jig.

OK Louie, there so is nothing new under the sun.

It is not immediately apparent at least to me) how Doolin gets the differing slot depths, whereas it is immediately obvious and intuitive how Dan Erlewine does it.

Louie, please don't waste your valuable time explaining the difference in the processes ... I will figure it out !

They're essentially exactly the same!

I think if John Greven were still posting here, he'd probably dismiss that jig and extol the virtues of the "convex" slot...

as opposed to the concave slot that Dan Erlewine does ? Tell me more ...

Dans concept is brilliant and he is obviously a talented woodworker. The concept of building the curved baseplate is the real engineering. Use of the glue on blocks is a standard practice in cutting angled table legs. I use a table saw and the technique he uses really scared me. That said, he may have used this technique for demonstration and not production purposes.

I would use fingerboards to hold the neck in position and a push stick to move the neck over the saw blade (as Dan did). Using that technique your fingers never go near the table saws blade.

Safety First and Ten fingers are good to have !
