This past weekend my wife gave me an early Christmas gift. She took me to woodcraft and bought me a new Jet 10in Proshop Table saw. I have listed the saws specs:

Exclusive 30” ProShop fence system with T-square design

Integrated arbor lock allows for quick, safe and easy blade changes

Heavy-duty cast iron table with T-style miter slot provides large flat work surface and increased cross cut capacity

Enclosed cabinet with exclusive leg stand design for easy assembly

4” dust port for increased dust collection efficiency

Rigid, left tilting cast iron trunnion

Powder coated paint for a long-lasting, chip-resistant finish

Steel extension wings for added workpiece support

Arbor Diameter: 5/8”

Arbor Speed: 3600 RPM

Blade Diameter: 10”

Dust Collection Minimum CFM Required: 350

Dust Port Diameter : 4” OD

Maximum Cross Cut: 21”

Maximum Depth of Cut: 3-1/8”

Maximum Depth of Cut at 45 Degrees: 2-1/8”

Maximum Diameter of Dado: 8”

Maximum Rip Left of Blade: 12”

Maximum Rip Right of Blade: 30”

Maximum Width of Dado: 13/16”

Miter Gauge Type: Deluxe

Motor: 1-3/4 HP, 1 PH, 17/9 Amps, 115/230V

Prewired 115V

Overall Dimensions: 39” H x 35” W x 60” L

Table Height (in.) 34-3/4

Table in Front of Saw Blade at Maximum Depth of Cut (in.) 10-1/2

Table Size with Standard Extension (L x W/in.) 27×44

Table Size without Extension (L x W/in.) 27×20

Table Size without Wings (L x W/in.) 27×20

So the question is should I use a thin kerf or full kerf blade with this saw???

Also what is everyones favorite blade???

I perffer full kerf. The blade will flex less and cut truer in thicker wood. The blade I like the most is Tenryu. I picked up one last week and it has been flawless. Smooth crisp cuts and best of all no burning when ripping white oak.

My saw has a similar sized motor. I find, for hard wood, the thin kerf blade cause less loading. This is for straight cuts (blade 90 degrees to the table). As Al pointed out, however, these blades will tend to flex more. Some of the flex can be reduced by using blade stabilizers.

I use which ever is sharper. Not that big of a deal.

I have a 1.5 hp Craftsman and use only full kerf blades. It tends to slow down if I am cutting 8/4 stock or bevel cuts but, as Gary said, if the blade is sharp then I don’t have any problem. But when the blade starts getting dull it does tend to burn and the feed rate has to go down to make the cut. With this size motor you should not have any problem with either size blade.

One note I would add is get a good quality blade. The ones that come with the saw generally are not top quality blades.

I have a 1 1/2 hp Craftsman and use Forrest WWII, thin kerf, cuts much better than the full kerf with this low power saw, I have had no flexing problems even when resawing 8/4×6 hard maple.

I prefer full kerf Forest WWII blades. I would only recommend thin kerf if you saw is 1 1/2 hp or less. Also, make sure that your splitter matches your blade.

Is your wife single? Does she have a sister? LOL j/k.

I think you will just have to try both and see what works for you and your saw.

I would suggest thin kerf under 1½ HP and your choice above that. If you go thin kerf and are concerned about vibration, you can get a blade stiffener.

Once you decide, you’ll probably want all of your blades to be the same thickness. On right tilt saws, it doesn’t matter if blades are different thicknesses because the right side of the blade is fixed by the arbor. But since your saw is left-tilt, the left side of your blade is fixed, so the right side will be in a different position depending on thickness of blade, so the distance between the blade and the fence (i.e. cut width) will be different. This can be aggravating.

I’m a left-tilt guy all the way, but I have thin and full kerf blades, and it drives me nuts. All my future blade purchases will be full kerf.

So I take it that you are changing the splitter with the blade – they must match if they are going to work. If you are not using a splitter, get one! You can get an aftermarket splitter for around 15 dollars.

In the US, there is a tablesaw related accident every 9 minutes.

It really doesn’t make a difference. Just remember to zero out your rip fence if you change sizes.

Greg, I guess you’re right, but changing the zero on my saw is a hassle – it moves all over when you tighten the screws – and I often change blades a half dozen times a day. It would still be much easier (and less chance of introducing error) to leave the scale alone and have a single thickness of blade!
