Saw set info

[Vernonv]

My lovely wife went to the local markets this morning and before she left I asked her to keep an eye out for a saw set ... well with her innate ability to spot a quality bargain (probably why she ended up with me ), she came home with an Eclipse No. 77 saw set, for the princely sum of $10.

Now it all seems to be in good nick and fully functional (from what I can tell). I would however like to know exactly what the numbers on the silver dial relate to. I would assume they simply provide greater or less set to the saw - but do the numbers mean something or are they only indicative?

From memory they are for tpi.

Thanks guys.

So does that mean that the higher the TPI the less set a saw has (looking at how this thing functions mechanically)? Or am I missing something (very possible )?

Pretty much, Vernon. The degree of set may be the same, but because the tooth is smaller the more teeth per inch, the amount of set is less (remember that you put all the set at the point of the tooth and use as little as possible - all you are doing is increaasing the kerf a smidge so the blade does not bind, any more means that you have to cut more wood to make the cut, as well as wasting wood, this also means you are doing more work - thiin kerf from small (but adequate) set makes for easier cutting

Hi Vernonv,

Great site for Saw Sharpening and setting.

Nothing like cuttingg some wood knowing that you sharpened the saw that made it possible

i can belive your wife new what a saw set was.

The number refers how many point the saw is , tpi plus 1.

Thanks all for the clarification.

Yeah, she's pretty clue'y when it comes to tools and stuff. What gets me is she had a pick of three different ones and (by the sound of it) picked the best - she liked the Eclipse because it was made in England and looked older and sturdier than the others.

She did well

Hi VernonV,

What every one has said is correct, the numbers relate to the pitch TPI or PPI if you prefer, but when you get down to it.....

The numbers are just that, numbers.. they do relate roughly to the pitch, but if you look at the anvil, you will see the depth changes (the point it bends the tooth at) as you rotate it, the less TPI (or PPI) the deeper the gullet, and the further down the tooth the plunger goes. As well as greater set.

When you get to finer than about 15 PPI, the eclipse 77 plunger is a bit too big, and you need a smaller plunger, the blue Somax (a 77 clone) is better for finer teeth.

Generally the amount of set depends on what you want the saw to do, if you are ripping thick stock to size, more set will give a wider kerf and less likelyhood of binding in the cut

Whereas a fine pitch dovetail saw you want minimal set to give a nice narrow kerf.

So it depends a bit on what you want the saw to do, as well as the actual tooth pitch.

Confused yet!

No, I think I've got the gist of it.

[weisyboy]

any chanceshee can find me one?

there aint any at the markets round here iv been looking for adges.

The markets are on monthly, so if you don't mind waiting 'til next months markets, I'm sure she could get another one (but maybe not an Eclipse 77). Do your care what brand/model?

[weisyboy]

that would be great.

i dont care what it is solong as it can set a saw.
