Any tips to tell if this circular saw blade needs sharpening or replacing?

Something like this:

with the arms coming down from my rafters.
with the triton blade guard on the end.

The splitter is there for a reason, not just to hold the dust guard.

[barrysumpter]

Yeah, kinda.

Went out to measure for the over blade dust hood and found the new blade kerf is 2.8.
Must have decided on the other ad.
Will have to test it after all.
Might build it anyway.

Product Specifications
Brand CMT
# Teeth 24
Blade Diameter 235mm
Bore 25mm
Grind 10deg ATB
Hook Angle 20deg
Plate Thickness 1.8mm

the plate thickness must not be the same as the kerf
my bad

The guard support is 2.8 by my digital calipers.
Way to close for me.

[Chrism3]

I've been using a 2.8 OK for some time.

[barrysumpter]

you must have yours calibrated exactly aligned.

Found the riving blade/Dust Guard support on the table top is out 1mm.
So the instructions need to include this issue.

Tested on 6mm ply.
Like skating on ice.

So smooth and easy.

The tear out is terrible.
(A quick pass over on my 18v Makita handheld sander sort thats out quick enough!)

Considerably more satisfying.

Then tested on 50mm x 50mm hardwood.

Slides so much easier on a new clean sharp perfectly aligned low tooth ripping specific blade.
With heaps of blade scratches left over compared to a 60 tooth blade.

So tempted to run thru the jointer to clean up.
Jointer depth is currently around 1.5.
Wonder if I set it at .5 or maybe .2

Thanks to all for their brilliant and consistent support with this topic.
Never slowed even during the Red Page crisis.
Much appreciated.

I buy Bosch and Makita blades for my 235mm Makita saw. Have a 20t for ripping, a 40t general use and an 80t for ply etc. All available from my local hardware.
