As promised, here are some pictures of the OPR, template and results. Plus a few of the unfinished toys.
This was fun! Searching for more uses for this beast.

I am confused. Do you sandwich another board between the carrier and fender patterns?

I'm sorry for not being more clear.
The patterns are glued to the carrier and they guide the carrier by means of the pin you see directly under the spiral bit in the first photo.
I didn't show the other side of the carrier as it is just the other side of the plywood that I made the carrier from.
The work, slightly less wide than the carrier, and just as long, is affixed (I use carpet tape) to the flat side. Then the bit is lowered into the work. The depth is set by a depth limiting rod, similar to how a plunge router works. I cut those fenders (3/4 wide) in 4 passes.
The carrier can be any size as long as it is larger than the patterns so the spacers can be glued on to the sides/ends. Larger is better so as to keep hands and fingers safe. My carrier was a wee bit too narrow. I used a piece of scrap. I'll build it larger, next time.

Good Job, Gene!!:D Your pattern carrying board is just as I had pictured in my mind! Very stable!

After seeing those beautiful little car bodies, I dawns on me that you could also make up a similar carrying board and use the OPR for the bodies, as well as the fenders. Then you could rout out 100s of cars - or at least as many as you can do until the template or the router bits wear out.

Nice work and Nice post!!!!

Would this be the same as an OPR? Using the SS with a router bit and a 1/4" chuck and shield, or a 1/2" chuck and shield, or the 1/2" pair with router bits.

It is an OPR. Free standing. Operates the same as the new one that utilizes the MKV.

Thanks, Charles.

I thought of that. Not sure I'd want to do it though. At least six passes per vehicle. However, There are parts that could be plunged, making bandsawing and sanding easier.
I also thought of cutting part way with the OPR and using the groove as a guide for the band saw. Don't know how efficient that would be, though.

I have never tried what you suggest. OPR is a special free standing or the newer version mounted on the Mark V. However the Mark V power head is considered under powered by many users thus a separate router is used in order to raise the power to an acceptable level. There are numerous other advantages to using the OPR set up over using a router bit mounted on a mark V power head. Jim
