Well, the monster shelving unit is almost ready. Another hour with the sand paper and maybe 2 with a brush and urethane and it will be ready to go.

This leaves me time for planning the next project. Windows for our greenhouse/garden shed. I see this as a good time to practice a skill I will need for some other upcoming projects…making glass panel doors. The plan is to essentially build a very shallow cabinet with no back to serve as the frame. To that I will attach face frames and then oversized glass panel doors.

I plan to buy a set of router bits to do this project. I have looked at Freud, CMT, and Sommerfeld. I have three requirements. 1, the set should be made so that determining the stile length is done via a set formula and NOT by trial and error. 2, the set should also be able to cut the mutton for multiple lights. 3. It must be able to cut rabbits for the glass and retainers.

Technique wise, the Sommerfeld set looks like it is top of the list. It is also top of the list price wise too! Is this a case of better infomercials than the others or are they actually worth the price?

What say you Lumberjocks? I would welcome any comments you may have.

I don’t understand how the stile length can be determined by the router bit set. Can someone enlighten me?

Just to give you more to puzzle over, Grizzly makes sets that answer your #2 and 3 criteria, both in router bits and shaper cutters.

Thanks Runs, that was my mistake. I should have said “length of the rail”. Let’s suppose the finished frame is to be 20 inches wide and made from 2 inch wide stock. If you use simple butt joints the rail would be 16 inches. But for tension joints the length must allow for the material removed in the milling. Sommerfield does this by making all of their bits 7/16 so it is just a matter of adding the correct amount to have the frame come out right. So I am looking for a set that uses some standard number to figure the length.

And of course, this is why I said I need to practice this skill on this project. I can see myself making a lot of high quality saw dust before I get a product I am happy with.
