   Rick, I think that chart is fine as a guideline for you or me but perhaps a newbee needs a little more info and needs to do some sample cuts to evaluate. The cut he is attempting is fortunately an easy one( compared to a complex profile) so the sharpness of the bit, the toughness of the stock, the length of the cutting edge engaged, the depth of cut and the feed rate are most of the factors to be assessed.

   We all paid our dues, I am sure due to the lack of good info back in the day till we could hear the tool loading up and got smart enough to slow down or stop trying to do an edge profile in one pass. It was a pleasure to do a nice edge with no burn marks or chatter tear out and no smoke or burnt router bits to clean, once we got smart. All the best, Paddy

   Dear Mr. Foot, do some tests on scrap of the same stock. Get a feel for the speed-I would start at 3- and adjust accordingly and be mindfull of your feed rate. Paddy

   I'd run it at max. Notwithstanding, in my view, that cutter has no correct speed for your application. Rather your stock should be routed in thickness stages with a plunger. You'll be lucky to see 200 feet (linear x 1.125) under your feet without serious wear to that tool.

   Unless the bit came with a specific warning about the maximum speed it should be run at, a bit that small in diameter should be run at full speed. You will not however, be able to take a cut 7/8" wide by 1 1/8" thick or even close to it in a single pass, although that may not be your intention being that you are template routing.

   You are template routing.. you cut and trued a template I presume. Then you used it to draw the pattern on the stock... then cut to within 1mm-2mm outside of that line on a BS or jig-saw. The template is then attached and you only have to take off 1mm-2m  which ain't much.

   I do it all the time with a 3/4" diameter 1 1/2" double bearing pattern bit and I do it full speed as again... you are simply nipping off 1mm-2mm if you trimmed just shy of the line of the intended finish line.

   Full speed ahead and damn the torpedoes... IMO :>)

   Bob,

   With all due respect to the knowledgeable members here, you should always consult the tooling manufacturer for recommendations on using their cutter(s). You can contact Whiteside here:

   With all due respect to Charles suggestion of contacting the manufacturer.. he is probably correct technically. When I personally stated I used full speed.. (which I do on average of twice a week using templates in oak over the past 4 years.. resulting in a very smooth cut using the method I described and...  absolutley no problem with the pattern bit).. in all fairness to technicalities, I am using an Eagle America pattern bit so perhaps I am not comparing apples to apples here.

   Sarge..

   who will continue at full speed ahead under the circumstances described using an Eagle America (not Whiteside) 3/4" x 1 1/2" double bearing pattern bit.. :>)
