Merry Chirstmas:

I'm getting ready to order cove & bead bits for a strip built canoe. The strips will be 1/4" x 3/4". My question is should I order the 3/8" dia bit or the 1/4" dia bit. Seems like I read somewhere to go with a larger bit than the actual material. I may bump my strip thickness up to 5/16" to allow a little more thickness for sanding. I'm not that concerned about weight.

Thanks

Chad
