Veritas fine tooth dovetail saw

[bugbear]

....

Surely as you rotate the anvil, the bend point (the spiral arris on the anvil) moves continuously up and down the tooth?

BugBear

Yes but the teeth you are adjusting for are longer or shorter so the bend may stay at the same relative position.

"may" appears to be purest optimism! I agree that it's possible you could change the saw-set, and the next tooth just "happen" to match the change you've made, but is seems damnably unlikely.

If that's not what you meant, what did you mean?

BugBear

If the spiral bevel thingy is properly designed - the 'bending point' will be in the same position relative to the length of the tooth for every tooth. So at 4 tpi it will be at n" at 8 tpi it will be n/2" (measured from the tip).

Well, that's not a property of the spiral, that a property of the labels on the spiral.

But the anvil is rounded on mine so there is no single bending point, and in any case the steel is a bit springy so the tooth won't be bent at a neat angle, but the principle will be the same.

You mean the arris rounded? As long as there's still an arris, it has a position (obviously...)

Or to look at it the other way - the further you turn the anvil the higher or lower the (hypothetical) bending point.

Yes, that's what I said. And for any given tooth, there's only one anvil position where that bending point is halfway up a given tooth size. Which is also what I said.

It's true enough, but I don't particularly want to pay £50 for a saw set. I think I'll pipper a few #77s off ebay for now.

I bought several recently - price from 99p to £2.50 + p&p.
I also bought a CK (CeKa) set, which is for bigger saws. It's a very neat design and a lot easier to use than the Eclipse, so it could be good to experiment with other unfamiliar makes and models.

I dunno, these damn c*ll*ct*rs... :lol:

What, this sort of thing?

Lots of experimentation fodder there!

I'd guess the CK one is this pattern:

That's it. The Hirsch 2.5mm. Looks fussy but very easy to use; the tooth tip locates in a little notch and the spring is lighter.
The Eclipse looks neat but is much less easy, in fact impractical for small teeth but better than nothing.
BTW You mean the arris rounded? As long as there's still an arris, it has a position (obviously...) rounded surfaces don't have an arris by definition (obviously...)

Even a rounded bend has a position - if you ask a plumber to make a 4" radius, 90 degree bend 6 foot along a 10 foot pipe, he'll know what you mean, and get on with it, no trouble at all. Common sense. Methinks you argue for the sake of it.

I wasn't arguing I was just trying to explain a few things to you! :lol:
