A customer dropped off a rush job today (needs it Monday morning). He is a local chimney sweep that, somehow, has been asked to replace some water damaged pilasters and trim around a fireplace. He has supplied the material and I am only supplying labor. The flat MDF needs to be fluted. I have the right bit but now guides other than a plain edge guide. I could probably get by with that, but thought that there must be a home made jig I could build to insure better results.
A quick look at YouTube turned up many suggestions on jigs from Festool, Rockler, and others, but I just do not have time to buy. Any suggestions?
Here's what's being replaced.
