I think they will serve you just fine. I have a set from Harbor Freight. At some point, the 3/4 and the 7/8 and maybe one or two more just weren't cutting the mustard so I replaced them individually with Freud. Each time I would go to the local Woodcraft, I would pick up one or two.

Those big bits should come in handy.

Off-hand, this is all I came up with without my coffee. I believe you could also make one somewhat similar, but out of wood.

I never buy sets of bits or the like. I prefer to just buy the one I want, then later buy whatever else I want, one at a time.

I have one of these. Not the best but it did help me guide the bit.

For a jig, I simply cut a hole in a piece of 2x material (on the drill press) that I could clamp in place. Might not work for every situation, but it did help guide the bit.

Note: Check out the picture. I was repairing a goof up.:surprise: I had lost focus and pulled the router out of the hole while it was running, and before retracting the plunge! It quickly tore up the hole and broke the bit. :frown:

The repair worked great.
