   Generally speaking slowing down the cutter should help. That said the bit itself has to be sharp and designed well. Some low quality bits burn their way through wood. Some woods are prone to burn. What are you cutting? What are you cutting with?

   Be sure to clean off any resin build up. The router RPM should be determined by the bit diameter...there are charts all over the web to suggest proper RPM. Regardless of the router RPM, be sure not to let the rouer linger... move it along at a clip that doesn't burn. It might be helpful to take 2 or 3 light passes, as opposed to taking the whole profile at once, which typically means you can't pass the router over as quickly.

   "slowing down the...feed rate should help"    Ooooops!  Backwards.  If indeed the feed rate is the problem, burning is happening because the cutter is staying in one place too long.  Feed rate needs to be increased, not decreased.

   Slowing down the cutter speed, as you suggested, accomplishes the same thing.forestgirl -- you can take the girl out of the forest, but you can't take the forest out of the girl ;-)

   You are so right! I should have edited that.

   Depending on the profile, you'll want to make the cut in multiple passes, about 1/8" deeper with every pass. If you're doing this with a handheld router and a bearing-piloted bit, you can clamp a simple fence to the workpiece and run the router base against the fence to limit the depth of cut.

   Make a next-to-last pass about 1/32" shy of the final desired depth, and then make a final pass that removes only that 1/32". As forestgirl mentions, you want to keep the bit speed up (if the router bogs down, you're taking off too much at a time), and you want to move the workpiece smoothly and evenly across the cutter (or vice versa, if the router is handheld).

   Steve's suggestion of taking multiple cuts and finishing with a very light cut is the best bet, though possibly more time consuming.Chris @ http://www.flairwoodwork.spaces.live.com

   "though possibly more time consuming"Perhaps less time consuming than redoing the entire work piece from the ground up? I think if I have spent the amount of time on a project to get up to the point of final edging, it seems foolish to rush the work at this stage.
   To me, it's about "fine" woodworking, not "fast" woodworking.BB

   High resin wood?

   Dull router bit?

   Slow feed rate?

   Good News! I solved my router bit burn problem by slowing the router down and taking off very little in each pass. It never turns out to be as simple as the guys on TV make it look.Thanks for the suggestions.

   Woodman,

   It never turns out to be as simple as the guys on TV make it look.

   Amen to that one.  If you watch New Yankee Workshop that fella has been known to burn a board or six, but you never hear him say anything about it.

   Do you mean to tell me Norm is not perfect? I thought he floated on a cloud of perfection.

   KiddervilleAcres | May 21, 2008 03:20pm | #16

   Oh he most certainly does float on a cloud, but methinks it might be from his burnin da wood mebbe?

   It's been said that a reason for someone to make jesty jabs is cause they have respect for them.   I do respect Norm to a degree but have long had a desire to see him make something without any power tools!

   I'd say even a EXPERT with a router will get that! OK, so not all woods but some.. I'd say you either sand it off or stop short of the final pass and take the slightest cut using a climb cut.. NOT recommending a climb cut unless you are VERY comfortable with your router use!
