I have sharpened a few saws now and I seem to get a good sharpness – i.e. the saw cuts through the wood very well, but….
They do seem to be a bit “grippy”, I do not think it is the sides which are clean and lightly oiled; the saws are also set (I think) it seems that the blades are just a little course in their sharpness but this is just my view.Any one else have this problem? Any idea what I might be doing wrong.
Thanks,
Mick19 December 2013 at 6:05 pm #24184I have this on my tenon saw but not on my panel saw. I think I may have got the rake on the teeth a bit too aggressive on the tenon; but I’m not sure. I’ve tried removing some of the set which only helped marginally.
19 December 2013 at 7:23 pm #24190Thanks Mat, I was thinking it might have been sharpened a bit aggressively. Really appreciate your comment, I will try to file it a little less harsh.
Mick19 December 2013 at 9:15 pm #24194If your file face is on the front of the tooth in perpendicular may just a tad aggressive. Angle file forward about 4ยบ, this may help if using a rip cut. Are you sure you have enough set. You could always over set and try saw if still too much set reducing by using Paul’s Hammer trick or dress each side with a couple of strokes on a medium grit diamond plate.
19 December 2013 at 10:25 pm #24195“Grippy” is a little vague. Does the saw feel like its dragging thru the whole stroke? If so, is it both forward and back or just on the push (cutting) stroke?
or
Is it smooth in the cut and then bites hard at a certain point in the cutting stroke?20 December 2013 at 6:25 am #24229Greg, not only do you draw well your written expression is spot on! That is what I should have written; the saw bites hard at the beginning and then sometimes during the cutting stroke.
I shall try a larger set but I think it is probably a tooth issue. I will try a less aggressive angle too.
Still so very new to all this so it is great fun learning and all adding to the experience.
Your help and comments are much appreciated.
Mick20 December 2013 at 6:33 am #24232Thanks Mick. Sounds like tooth angle is your issue. Too aggressive. Increase the slope on the front of the teeth. Watch Pauls sharpening video again and make note of how he says to hold the file in relation to the tooth.
20 December 2013 at 5:48 pm #24270Thanks Greg, saw sharpening practice for me this weekend.
Merry Christmas.Mick
22 December 2013 at 10:42 am #24351Firstly, thanks to everyone for the help and advice; it really helps to get opinions and ideas.
I have slightly altered the angle by taking extra care to keep the vertical side of the file true and also used the eze lap sharpener technique. the result is a nice sharp saw that cuts………
smoothly!
success!
I am pretty sure the issue was caused by a too aggressive angle.
other things I changed was the pressure I put on the file; i think i might have been a bit heavy handed before.
anyway I now have one nice sharp and smooth cutting saw, just got to correct all the others now.Happy Christmas
Mick
22 December 2013 at 11:15 am #24352That’s great to hear; Now I need to try the same over Christmas! Have a good one yourself ๐
22 December 2013 at 2:19 pm #24362Glad you it worked out Mick. Its very satisfying to sharpen your own saw and have it cut smoothly.
Mick I just recently took my first turn at saw sharpening, I ended up with too slow a cut, its an eight point cross cut, and I set to 12 per book suggestion. So I will do as you have done and try it again changing something. Thanks for posting so we can all try to learn.
