I had a small job to do to help my Father in law cut a long table in two to make...two tables. I thought I could get the old Heavy GMC out but it is a bit of a clunker so I treated myself to a little Makita.

The new legs were already temporarily in position to take the weight, so I clamped on the straight edge and let rip.

Hmm needed to force the blade, lots of blue smoke, had to trim the edge twice. I was expecting better.

Afterwards I thought. “Now why was I using a 24 tooth tct blade to cross cut 3/4” Jarrah planks with a 185mm Circular Saw?”

It really was underwhelming.

Perhaps I should have got a 40 or 60 tooth mitre or cross cut blade?

The first thing that comes to mind is that the timber was closing up on the blade as you progressed, usually a good idea to put a wedge in the cut as soon as the blade is wholly in the timber

You also said that the top was temporally attached to the legs so was that 4 legs per the completed 2 halves if so I also suspect that there was a very small difference in height and the floor may have had a hump under where the to pair of adjoining legs which resulted in the bottom edge of the cut closing up on the blade

I think you may be right on all counts. Probably some unevenness and pinching the blade as you say.

live and learn

+1 for the cut closing on the blade. Even a cordless saw should have no trouble with 3/4" Jarrah, I know they can do 2" American Oak (it doesn't like it, but it does it).

More teeth makes it harder to cut, not easier, but you get less breakout.

Problem solved.

Despite checking before I put the blade on, I had put it on in fact back to front.

It has arrows showing the right way on both blade and guard, somehow I turned it round on fitting.

I must be losing the plot.

Sigh!

You're not alone. Been there, done that.

Thanks All,

Honesty is a poor substitute for competence but I am motivated to try to be more careful next time.

regards
