Table saw blades
Hi. I’m having a problem finding a multi purpose 10 inch table saw blade that has a kerf of exactly 1/8th inch. I own a Ridgid table saw, but the two Ridgid blades I have come with a kerf that is just less than 1/8th inch. I recently bought a Bosch blade that was supposedly 1/8th inch, but the kerf is just enough wider to mess up my objective. All three are close, but they still leave too much play when doing below.
I like to make boxes with miter joints and then strengthen them with miter keys. It would be so much simpler if I could cut the slots at exactly 1/8th and then plane the material to be used for the keys down to 1/8th inch. Perfect fit every time, right?
Now I have to sneak up the planing so that the keys are just a little thicker than 1/8th or sneak up on it with my thin cut rip cut jig.
Everyone and Home Depot or Menards doesn’t know what I’m talking about, and each manufacturer I look up on the net doesn’t include the size of the kerf.
Any suggestions? Thanks.
Maybe I'm not following you, but if you can plane thicker stock down to get a good fit for a 1/8" kerf why can't you just plane the stock down to match the width of the kerf no matter what size it is? What is so special about 1/8" thick?
There's nothing special about 1/8th of an inch other than simplicity. My planer has a guage/stop for specific widths, the smallest being 1/8th. If I set it there, the planer won't let me go any thinner than the 1/8th inch with. So with an 1/8th inch kerf, I can get a perfect fit every time without have to tweak things or sneak up on them.
If my kerf is a little less than 1/8th, the miter keys I make will need sanding. If it's a bit wider than an 8th, I'll end up with too much slop in the joint.
Again, just simplicity. Actually, I found a list of saw blades with their kerf size in an article (in FWW) reviewing saw blades.
I guess I just don't understand why manufacturers sell blades without this information on the packaging. So.....thanks for responding, but I think I found my answer.
Jim,I think that you will find that the posted widths of the blades are nominal, one brand of a 1/8" kerf blade probably won't create the same size kerf as another blade also rated 1/8". In most applications the width of the cut isn't important and the makers don't worry about getting it perfect.As for your planer, it probably doesn't create stock that is exactly 1/8" thick either. You may find, if you look inside of the machine, that there is a bolt and lock nut in the preset thickness mechanism that will allow you to fine tune the thickness settings. You can also place a piece of 3/4" thick melamine surfaced MDF, on you planer's table which will then allow you to go below 1/8", just be careful that you don't actually cut into the MDF surface, it will dull the blades.
