Let's play a game...what do these belong to?

[Anthony Whitesell]

I 'inherited' a bunch of wood working stuff. Some items I don't know to what they belong.

Item #1:
P9190475.JPG
A full circle router base. But for what router?

Item #2:
P9190476.JPG
Router plate with one flat edge. Larger than item #1. Is it for a plunge router? What router?

Item #3:
P9190477.JPG
Router plate with bushing insert. Looks universal, but can't find the holes that would fit by Bosch 1617. Is it universal or for a specific router, which one?

Item #4:
P9190478.JPG
Looks like 3 router bushings of two different sizes. Any idea which router base they fit?

Item #5:
P9190471.JPG
All metal router table ring inserts. Any idea for which router table or router lift?

One and two sure look like my Makita plunge and I know they made both a round base and one with a straight side. No clue on the others.

As I can figure #1 and #2 can't be for the same router. #2 is substantially larger than #1. The mountings aren't even close. Neither line up with my Bosch 1617. I also have access to a 3HP PC base, and they don't fit that either.

#2 looks like the one on my Hitachi M12V. If it is 7" OD and 3.5" id then it probably is.
#3 is a universal base. I had./ may still have one. I think it was made by Vermont American among others http://vermontamerican.com/products/guide-bushings/
#4 best guess would be Craftsman but I don't know.

3, 4, and 5 look like Sears items.

#1 looks like a Makita base and #4 look like Makita guides but if it is 2 different sizes it will depend on which ones fit #1. Cheers

Just a suggestion, laying a 6" rule in the pictures would help give scale to the items.

The last (red) ones look like Ryobi oscillating sander inserts, but they aren't a full set.

Metal inserts for an OSS? That would be a first that I have seen. I thought for a (higher end, metal?) router table plate. I know they don't fit my Rouseeau lift.

I thought of the ruler too late. Only the last picture has it, then the battery in the camera died.

Number 3 is indeed a "Universal router base". Why it won't fit your router may be due to some missing pieces.
The slotted holes are also mounting holes. There were a set of washer-like inserts with a countersunk head to admit a baseplate screw. Since they were in slots, they could slide around in the slots to give a wider range of spacing for some routers.

I have one and it fits my PC 690, and I may have mounted it to my Bosch 1613 also.

They're pretty common. This is what they look like for my BOSS spindle sander:
