Slot cutting with no grooves problem

[Lloyd James]

Hi, I make toys and I want to cut 1/4" wide slots only .050 Deep. I have to make
four vertical slots and 2 horizontal lots that cross each other. I used a dado set
to do my first prototype and I get small grooves that cross each other. I know
dado blades have teeth that got to a point on the outside of the blades. I looked at
router bits and they all seem to come to a point on the diameter, so I would get the grooves with them too. I looked into saw blade types and found that there are Flat top saw blades. I could only find 10" dia. blades with 18T and I don't think I will get the best
finish when I go across the grain with only 18T. I read FT blades were made with
18-30T, but I don't know what manufacture makes one with more than 18T.

The toy is going to be a small sink console and the size will be 1 1/2 sq. x 4 1/2 long
of solid hardwood. The slots will give the look alike effect of front doors. The foucet
will be made of 5/18 D. and 1/8 D. polished brass rod. There will be a .22" thick back
flashing.

Think that over for a moment . . . . . router bits spin. One flute could be longer than the other and you would still get a smooth bottom the depth of the longer flute, eh?

+1 to what Glenn said regarding the router bit. Also, you can get a 40 tooth WWII from Forrest with the flat-ground teeth. I think they call it a "#1 grind".

Not sure if this is what you're looking for, but here's a Bosch 60t FTG. http://www.amazon.com/Bosch-CB1060L-10-Inch-Crosscutting-8-Inch/dp/B000EPOLWY/ref=sr_1_1?ie=UTF8&s=hi&qid=1237766386&sr=8-1

Or a Freud box joint blade set. 8" dia, 20 teeth. Cuts 1/4" or 3/8".

Thankyou for some good suggestions, I did not know about the Forrest Flat top
blade, and the box joint tool idea might work. I probably would never think about
the Freud box joint tool, since I have not made any box joints.
I will have to make some drawers soon. :)

Lloyd, any blade manufacturer will produce just about any blade you want in any grind.

You just have to contact them and order one.

Regards, Rod.

Any blade with raker style teeth should give you a flat bottom cut. If these are blind cuts, just be sure you raise the saw blade into the work and don't lower the work onto the moving blade.
