Default Reverse rotation router

I am building a duplicator that will cut two pieces at one time. I am trying to find a router that counter spins so I will have one router spinning clockwise and the other counter clockwise.

I have had no luck finding one. I know they are available but can't find any. I have read up a little on reversing the spin on a router but I am not sure if that is the route I want to go. Safety reasons and all.

Thanks.

Hi BJ

Sounds like you are looking for more of a elec. mixer than a router the kind they use to make cakes,etc...

Im new to routing and wood working in general so please don't point and laugh if this is silly, but would having one router mounted from under and one above in theory reverse the directly it will be feeding from and work in the same fashion? like I say if its a completely silly idea just ignore me lol

Have you had any luck finding bits that cut the opposite direction?

The reason it won't work is because it will be incredibly complicated to build, will take up tons of space on the table, if it was an open bottom it would be plausible but I am using a downdraft dust collection. There would also be the issue of how it cuts. Since I will be cutting 3 dimensional from the top it would be nearly impossible to get the proper cut if one of the blanks were to be cut from the bottom, and then I would still have to worry about the swing issue, one would be swinging down towards the blank and the other would be swinging away from the blank.
I had not thought of this option previously, it made me stop and think. But then I realized the guy I have building the dupe machine would strangle me if I came out with a change like that.

This was going to be another topic but since you brought it up. The only way to get reverse directional router bits would be to have them custom made.
I came across Saburr Tooth bits and the pics look like they might be dual directional, but their website stinks so I was not able to look around. They seem to have good reviews but could not find any actual experienced reviews.
If anyone knows of a place that supplies quality bits that do both directions, I don't like to mix brands on a project like this, I would be very grateful.

There are no routers that turn in the opposite direction. Period.
Bits would cost a fortune to have made.

Reversing a universal (brush type) motor isn't a problem, just reverse the field connections relative to the brushes. The problem arises with the cutter, it would have to be custom made, unlike twist drills which are available for both directions and are used in industry where many holes are drilled at the one time, some going clockwise others anti-clockwise.

Well, now. I thought everything turned opposite directions depending on which side of the equator you were on. Naw..airplanes would fall out of the sky...or fly backwards.

Seriously, I'm glad you abandoned the idea. Even if it were economically possible, it would seem to be incredibly dangerous.

Hi BJ

They now make and sell a power hand saw just that way maybe it time they may do the same for the router but I don't think so right now..

They do it all the time in the big wood mill shops but with 2 or more router motors..lots of luck with your quest..
