Title: Using a round over bit
Post by: malc on November 02, 2010, 05:01:26 am
I am new to using a router and want to round over the edge of some 1 inch thick oak the contour is quite complex with several sweeping curves in the shape of a treble clef. My question is is it best to use the router freehand or in my table. The work piece is about 17 inches long by 5 inches wide. I intend to put a 1/4 inch round over on it.

It is always safer to use the table.  If you can get to everything using your table I'd suggest using the table as you can keep the work more stable.

dunk is right malc, use your table. Let the piece ride along the bearing. Start slowly so it doesn't grab it, then once you are onto the bit try to keep it moving in one smooth motion. Watch where your fingers are, and remember this very important NOTE: never put your hand directly over the bit, if a bit comes loose it will go straight up. I know this for a fact it did it to me when I was using a rubber coated push block, I knew something was up when I smelled the rubber. Be Careful.

Another suggestion is not to try to take off the whole edge at one shot.  You significantly reduce the chances of tearout if you make successive passes removing a small amount of wood at each pass until you get to the final pass.  Also be sure you understand the correct direction to feed the wood into the blade.  You may well be aware of these suggestions, but you did say you are new to routers and there are a few tricks in the bag.

A table is probably the safer method.  Make sure that you are feeding into the cutting side of the bit, and not taking too heavy of a cut.  If you are working on an irregularly shaped piece, make sure that you start your cut pivoting into the cutter from a starting pin.  This will give you some control so that the bit doesn't kick the stock back at you as you cut it.

If you have any questions, you can always check out routerforums.com, or Bill Hylton or Patrick Speilman's router books at your library.

Thanks folks, I have been practising on off cuts and will be using my table, seems a whole lot better with more control. As for books I have just got two Patrick Spielman router books. The pictures in his 'The art of the router' are enough to take your breath away!

I agree with using the router table. I use mine to round over edges all the time. Everyone has given some good suggestions.  8)

    I always route the ends first. Then I route the sides. I try to make several passes. Dave 8)

I have heard of the Bosch model, guess I will need to look into to it.
