Topic tags/keywords: question saw filing sharpening

To the hand saw users out in there Lumberjocks land, I have a question regarding my intended sharpening of three hand saws I own:

In total, I have 6 hand saws, two of which are 26” panel saws & one a relatively new PAX Dovetail saw – Rip Cut, none of which are under consideration here in this survey / question. What I am about to sharpen soon, now that I received my Lie Nielsen package of saw files, are the following three saws:

16” blade length (handle dimension not included) Disston back saw, currently filed 12 PPI Cross cut, 3 3/4” cut depth
14” blade length Disston back saw, currently filed Rip Cut with 13 PPI, 3 1/2” cut depth
12” blade length Jackson back saw, currently filed Rip Cut and 13 PPI 2 5/8” depth of cut.

My question is:

What method of filing (Crosss cut versus Rip) would you find most useful if you were to apply it to these three saws, assuming the intent is to use them as much as possible for furniture work; tenon, dovetail, and other hand saw use? I don’t plan to change the PPI, because I’ve found these do a better and faster job than the 22 PPI PAX, even in their current state of dullness.

Thanks in advance for the advice, I’m looking to make any changes to these saws once – for all future use.

I would file the 16” as rip, file the 14 as x-cut, and leave everything else as is.

16 tenon
14 carcass
12 DT

Adjust things after you Have worked with them a bit. Slow adjustments tend to work out better over the long haul.

It would be helpful to know the depth of the blades on the three saws. The 16” probably is pretty deep so Ryan has it. But sometimes they’re odd. Also some people recommend a crosscut dovetail saw for some uses and since you have the other Pax, that might not be a bad way to go for you. A 22 ppi saw is for pretty fine work so if you’re not using it for that it’s going to cut slower than you’d hope. So having a lower ppi rip filed dovetail might suit you better than having it crosscut. It’s up to you in the end.

Tim,

I included the depth of cut above, 3 3/4”, 3 1/2” & 2 5/8” depths respectively.

If this changes anything, please let me know,

Thanks

I would agree with Ryan. If you’re feeling adventurous, you might try a hybrid approach on the 14”.

Have your say...
