I have a 110mm square laminated pine post.
I want to put a 45 degree bevel on the top of the post, around all four edges.
I don't have a mitre saw, but I do have a plunge router and a 45 degree chamfer bit.
Working on a scrap section of post, and chamfering from the sides of the post, not the top (that is, I rest the router base on the side of the post, bevel that edge of the top and then turn the post onto a different face) I've found that I can't keep the router level -- not enough of the router base is on the post.
Is there some jig or trick I should be using? Or is a plunge router an unsuitable tool for this job?
