Performing round overs

[cole]

Merry Xmax can someone tell me the best way to get 1/2in roundovers on my speaker fronts. I have a jig saw, a router, a drummel, a powered sander and a chainsaw.

Easiest and best way is the router with a 1/2" roundover bit. This is best done in a router table.

HTH,
Bill

That's the best way to do it with your arsenal of tools. Just be sure to get a carbide bit and not the cheapy high speed steel stuff. The carbide will last a helluva lot longer. My 1/2" roundover bit has been used like mad and it still cuts a very nice profile. After routing I usually take some 400 grit sandpaper and go over where I've rounded things over to smooth it all out. This isn't so critical of a step if you are veneering but if you are painting, it does help the finished piece look just that extra little bit nicer. A cool thing I've been using lately is the sanding sponges 3M has out. They are available in a few good grits and they conform nicely to the contours of the piece you are working on. They are available at any of the big home improvement store and are right next to the regular sandpapers.

I used a chainsaw to cut... Never mind. I don't have a router that can accommodate the 1/2" shank of the 3/4" roundover bit, so I glue a 3/4" quarter round on the baffle. Works just as well. That's about to change however, coz my wife said she doesn't know what to get me for Xmas, therefore she's giving me cart blanche for a trip down Home Depot lane. So Hong's going to get a new 1/2 shank Ryobi router, a 3/4" roundover bit, and a new table saw. Muahahahahah....

Hi there,

In addition to the suggestions, I would like to add to take a couple of practice runs with some scrap pieces. This way you get a "feel" of how the router and the bit are working. You will also get an idea of feed rate. This way, if something does look quite right, it's scrap pieces and NOT your speakers. You can make your adjustments from there.

And please remember to wear goggles and an approved dust mask. You don't want to be seeing your speakers with only one eye.

Use the router as suggested. 1/2 inch roundover is not too bad, but depending on your router and the type of wood you are routing, you may want to consider doing the roundover in 2 passes. You can use a guide board to make two 1/4 inch passes or sometimes I do a 1/4-3/8 roundover first and follow that with a 1/2 inch roundover. That way you can maintain a slightly faster feed rate which will prevent burning.

Yes, safety is important, and comfort helps to be safe.. Be ready for the snowstorm of sawdust, especially if you graduate to a 3/4" bit!! ;-)
