Orbb Posted September 30, 2015 Report Share Posted September 30, 2015 I have been trying to resaw some alder and have had tremendous difficulty - probably a feed rate of 1 inch per 8 seconds, with a lot of pushing. My saw is a 14 inch, 1 HP Grizzly with a 6 inch riser block. The blade is a Woodslicer from Highland Woodworking, and it does not have too many hours on it. After making little progress last night and tripping a breaker at one point, I Googled to see if the saw was too underpowered. A lot of folks say no, that they are able to resaw with a 1 HP Grizzly. I also cleaned the blade (it did have some built up dirt on it), but it did not help. That makes me think the blade may need to be replaced, although I really haven't used the saw enough to justify it. Before I plunk down the money for a new blade, how do you tell if it is time for a new one? Quote Link to comment Share on other sites More sharing options...
wtnhighlander Posted September 30, 2015 Report Share Posted September 30, 2015 Get a new one when that one breaks. If the blade doesn't have carbide tips, you can re-sharpen it quickly with a dremel-style tool and cutoff wheel or diamond wheel. I have done it myself, right on the saw, and it makes a tremendous difference. Here is a good example from Matthias Wandel 1 Quote Link to comment Share on other sites More sharing options...
AceHoleInOne Posted September 30, 2015 Report Share Posted September 30, 2015 (edited) Before we suspect the blade....do you have your saw properly tuned everything is adjusted correctly? Is the blade 1/2 or 3/4 or ? inch? -Ace- Edited September 30, 2015 by AceHoleInOne Quote Link to comment Share on other sites More sharing options...
4square Posted September 30, 2015 Report Share Posted September 30, 2015 How many TPI is the blade? For resaw it shouldn't be any more than 5 TPI. The gullets of the blade should ride just "off" the tire on the top wheel when making adjustments. Cool blocks or bearings should also be adjusted just behind the gullets. Try making some adjustments before giving up on the blade. I buy all my blades from Grizzly and can sometimes get as much as 1 year out of a blade before it snaps. (sharpened a few times) Quote Link to comment Share on other sites More sharing options...
Brendon_t Posted September 30, 2015 Report Share Posted September 30, 2015 How tall a piece are you trying to resaw? I resaw successfully with that saw, 1/2" wood slicer. My best results come from 6" and under.I Have done a few 10" boards when I hado to but the progress was very slow and the power just wasn't there.

Barron Posted September 30, 2015 Report Share Posted September 30, 2015 The Wood Slicer is designed for resawing, and I have learned that it really should be saved for that purpose. Alder is pretty soft, so if you are tuned up properly, change the blade and things will probably go more smoothly. Quote Link to comment Share on other sites More sharing options...
ColinF Posted September 30, 2015 Report Share Posted September 30, 2015 I resaw with a 3/4 horsepower saw, and a 1/2" woodslicer, in my experience, the woodslicer dulled what I would consider kinda fast, but it still cut ok, just had to slow the feed rate a bit, but I can resaw 6" wide hardwoods without trouble.

Orbb Posted October 1, 2015 Author Report Share Posted October 1, 2015 Thanks for the responses and sorry for the delay in getting back. It is a 3/4 inch 3 tpi blade, and the board I am resawing is around 6" . I may do a complete re-tune of the saw to see if that helps.

AceHoleInOne Posted October 1, 2015 Report Share Posted October 1, 2015 I use to use the 3/4 blade. It's a lot of blade for my Delta 14" BS with a 6" riser block for resawing. You need horse power to run those blades, so I was told. Often times the kerf would close around the blade causing friction. I would have to put a little wedge in the back of the board to keep the kerf open. Also the blade is thicker and more kerf thus wasting more wood.Try the 1/2 3 tpi blade. Works great on my saw. -Ace- Quote Link to comment Share on other sites More sharing options...
Workofwood Posted October 1, 2015 Report Share Posted October 1, 2015 I'm sure this isn't your problem, but regardless of how dumb it is, I was doing the same thing and at that feed rate. I realigned my saw and did everything I could think of. It turned out my blade was upside down... Just in case, check and make sure the teeth are facing down. Sometimes those dumb little things can slip past you. Quote Link to comment Share on other sites More sharing options...
Beechwood Chip Posted October 2, 2015 Report Share Posted October 2, 2015 But there's less drag if the teeth are pointed up - it's more streamlined! 2 Quote Link to comment Share on other sites More sharing options...

Sometimes those dumb little things can slip past you. Reading that made me jump up and run out to the garage to check - they are facing down. Actually, if they were facing up, you would have never heard from me again. I will be trying the fixes this weekend and will give an update on what transspires. Thanks for the all advice.
