New to this forum. Hoping for some suggestions from experienced woodworkers.

I’ve been experimenting with ripping blades from Forrest (20T 1/8 kerf WW10206125), Freud (24T 3/32 kerf resharpened many times) and Carbide Processors (24T 3/32 kerf custom made with thinner plate) on a 10” 1.75HP Craftsman TS. I’m definitely maxing out my saws capability with 4-6” thick hardwood (ash and walnut) stock. I don’t have a band saw so the only way to rip this lumber is with plunge/opposing cuts. Would I get better results with even fewer teeth. If so, how many teeth would give me the best plunging/ripping performance. Glue line cutting isn’t important to me. My opposed cut boards always require planing or joining anyway. What about kerf. Is there a good balance between strength and reduced load on the saw. How about tooth angle and shape. I know this is a ton of questions. I would greatly appreciate any suggestions I can get.

you will probably just have to keep doing it this way
just don’t go for to much cut
maybe raising the saw after cutting both sides
till you get to the center
for ripping
the 20 tooth with flat teeth should be best
more room for the stringy sawdust ripping creats

You’re using appropriate rip blades for a 10” saw.

I’d look at upgrading the saw or getting a bigger motor if you
want better performance.

I’ve had best success using a good 3/32” 24T TK for something like that with my former 22124 saw….Freud LU87, Infinity 010-124, DW7124PT, CMT 202.024.10, etc.

I’ve ripped boards like your describing on my tablesaw many of times. Last year about this time I was doing that exact kind of ripping and I was halfway through a 3’ rip when my 7 hp motor started to bog down. I couldnt believe what I was hearing. Standing there knowing something bad was about to happen I decided to let the board go, jerking my hands back out of harms way and let the board go flying. Well I wasn’t fast enough, the board was kicked across the shop while my fingers stayed there getting chewed up by the blade. I cut the tip off my thumb, ripped one of my finger nails off and ripped one of my fingers in 2 down to the knuckle.

There was an extreme amount of stress in the piece of wood I was cutting which caused it to pinch the blade. I was in a hurry that day and its easier on my saw to remove the guard and riving knife together than just pulling off the guard. I’ve been kicking myself in the ass ever since.

If I had to do this type of cut on my tablesaw again I would make sure there was a riving knife in place.

I really appreciate the great info. Especially concerning the riving knife. Allow me to make the question more specific.
If curiousity was getting the best of you. And you decided to order a couple more custom blades to try just for kicks. What specifications would you request for:

Number of teeth
Plate thickness
Tooth grind angle
Tooth hook angle

Thanks again for the interest

This brings back memories (bad ones) of working on my old, long-gone 1.75 hp Delta. 4” to 6” is way beyond any 10” table saw and should be done on a band saw if possible. But, I Know your stuck. So if you are going to do this you want freest cutting blade with the fewest teeth. A flat top grind (FTG) dedicated ripping blade with 20 teeth is probably your best bet. Makes sure its sharp. Good Luck.

you could always cut it with a hand saw after making the initial cuts on the table saw
