| I need to cut a 12 in diameter circle in a piece of q/2 in plywood with a jigsaw. It will form a lip for a bucket so don’t need a jig to get the circle perfect, but do want to leave as clean an edge as possible (bucket is embedded in potting bench and will be put in and out often). What type of blade should I use in the jigsaw? Any other advice/tips? Thanks in advance |

You can use a router to cut a very clean circle. There are commercial circle guides available, but you can make your own easily enough. You will need a piece of 1/4" plywood that is about 6" wide and 12" long. Take the base plate off the router and use it as a guide to make holes in the 1/4" plywood so that you can attach it to the router in place of the base plate. Cut a hole in the middle to allow the bit to come through. With the 1/4" plywood installed on the router, mark a spot on the plywood 6" back from the outside edge of the bit. Drill a hole in the plywood at that spot and drive a nail into the 1/2" plywood through that hole. This will serve as the pivot point for the router. Using a straight bit, make passes 1/8" deep until the router cuts through the plywood. You need to put a piece of scrap underneath so that you don't carve up your workbench. This will give you a very clean hole that is the correct diameter.

Thanks. I think that's what I'll do...my jigsaw is a bit underpowered anyway.
Let us know how it comes out.
