Thread: Cedar Tips Please

...bandsaw might be the go..
Or, sounds like the timber is binding on your fence as it's going through the blade.
I have the tail of my fence about 0.5mm further away from the blade when doing big ripping.

Thanks Glenn
Could be
Tried it in a friends large saw too and had the problem and this was a 10hp 3ph saw. Changed the sawblade to an old non tct open tooth blade and seemed to be better but I don;t know where I could get an old 12in blabe to fit my saw. Any idea if they're still made?

Yes they are still made and you should be able tto get one through any good saw service or decent tool shop. Tct should cut as well or better though and for much longer. Cedar should cut quite easilyit may be possible that you need a blade with less teeth and a more open gullet if the slabs are very thick but I imagine that the slabs would not be more than about 75mm thick so chip clearance shouldn't be a problem. you really need to give a bit better description and some photos so that people can be of more assistance.
have you tried cutting it with a handheld circular saw and if so what were the results? if this cuts it alright then you should not have a problem cutting it with a table saw, and if it does cut it alright then it means that something in the setup of your saw is wrong and it is compressing against the body of the blade which will be visible on the blade as rub marks. Either that or you are getting a build up of sawdust in the cut.

The timber isn't closing on itself have the cut is it? Does your tablesaw have a riving knife or splitter on it?

blade in the right way... sorry i usually only put the blade in backwards when i cut something to short and need to make it longer again. sorry again

try winding the blade up to full height and if you can pull the ripping fence back to near the centre of the blade

Check to see your slab hasn't twisted. This will cause the blade to bind as you run the slab over your saw table.

Don't ask me how I know this.

but have checked all of the above.
I'm cutting 4inch slabs into 1inch boards.The furry fibrous nature of the timber tend to gum the tct blades up. I've tried some smaller sizes with an old smaller non tct blade and seem to get a better cut. I will try to find an old 12in open tooth blade from other sources. Thanks for all the good advice

you should use a ripping blade [less teeth and more clearance ] the 80plus teeth of crosscut s are not designed or good for wet??? timber , cedar can be fluffy or fibrous . but a good ripping blade& riving knife should handle it fine . make sure the blade is well above the top off the wood though. your local saw doctor should be able to set you right . feel free to drop some off to me and i will show you ho its done cheers Bob

Cheers Bob
Have got a better quality blade now, The blade I was usinfg only had 40 teeth but was of questionable quality. Pretty flexi too. New blade is 32t and seems to be cutting quite clean and fast.
The old lesson is, you get what you pay for.
