Thread: Glue Line Blades?

I read the same article & was just as interested. I bought a CMT rip blade from carba-tec last week & while it sure does rip well it also does leave plenty of saw marks in pine.

Freud and Infinity make the glue line cut blades, but fence alignment and technique also come into play.

Dunno if CMT have yet made a blade that they claim will make glue line cuts.

Edit to add: I did use a CMT SCMS saw blade ( 80 teeth) and it gave a good finish, but the Frued 80 tooth is smoother

I bought a freud glue line rip blade but have not had a chance to use it as yet (only received last week). Will let you know what I think when I use it - probably next week.

I wasn't offered any glue line blades to add into the review, but those I did (some other Freud blades, some CMTs etc are all documented here, with lots of photos so at least you can do the side by side comparisons yourself.

Quite amazing, not at all what I expected. From the photos, it seems that the combination blades consistantly do a cleaner job than either the rip or crosscut blades...

I had a go with my glue line blade today. Very pleased with it. I ripped some blue gum, pine and tassi oak with my 24 tooth rip blade and then with the Freud Glue Line Blade. I did the blue gum first and I think I fed it to slowly as I had a little burnishing in part of the cut. My photos are not as good as Stuarts but hopefully you can get the idea.

The sequence is the glue line blade and 24 tooths cut side by side, the glueline formed by the 24 tooth then the glue line formed by the Glue Line Tooth Blade repeated for blue gum, pine and tassie oak. I was very pleased with the tassie oak as the glue line almost completely dissapears. The blue gum was not as good but I think that may have something to do with feed rate. In any case even the blue gum would take little more than one shaving of a very fine jointer plane for exacting work. the pine and tassie Oak could be glued straight from the saw.

Not perfect but very good.

Interesting sequence. More scoring that I would have expected given the blade's rep, but as you say, feed rate has a bearing.

Unfortunately to do proper test you would need a power feed. The sad part is that there is no blade which can entirely compensate for technique - bugger!

Hi All;
Oh my gosh, unbelievable! All the hours that I've spent sanding out blade marks! Should have done this years ago..

Ok, might have had something to do with the table saw I was using (see photo)...

But these blades cut so smooth... The glue line blade also works well as a crosscut blade..

Wonderfull!

Freuds website discusses each blade in their seemingly endless range. They have a couple of blades they claim offer excellent finish. From my reading of their website it isn't simply tooth count but the design and manufacture of the tooth sides etc to get that result.

Unfortunately as is so often the case the ones that deliver the polished finish are amongst the most expensive. The one I thought would be the go at 12" size was about $120US at most places that sold it in the US. Assuming they would sell international you could probably land it under $200AU.

10" is about $85US plus plus.....

I'm not suggesting freud are superior, but they do seem to have amongst the most comprehensive websites. Some interesting reading.
