1) How many passes did it take to make the raised panel?
2) Did you run the wood over the top of the bit or was the wood between the table and the bit?
3) Does the OPR table simply set on the the SS main table? 4) Is there any way to use the table as both a router table and OPR table?
5) Is it possible to use a router table and insert the OPR inserts into the router plate to allow you to use the OPR?
Guys please keep the information coming on the Overhead Pin Router. I have to upgrade my router table and I'm bouncing all over the place looking at my options. My biggest problem is my present routers are not round body routers so I can't use them in the OPR.
I wish Shopsmith had that combo deal back where they offered the OPR and PC router together.
6) Has anyone done any mortising on the OPR? 7) How about tendons?
More info please!!!!!! I think the OPR is the best kept secret Shopsmith has and they for some reason simply refuse to talk about the capabilities of the OPR....
More info !!!!!!!!!!
Sorry about adding numbers to your "quote", but had to in order to keep my answers organized.
1) It took 5 passes per side/ setting. I was going to route 1/4" deep so I did it in 1/8" deep passes. (being cautious - didn't want to strain my 1/4" shaft bit). So 10 passes per side
Then a couple of little clean up passes to clean up any small ridges. As I routed both sides
of the 5/8" panel - there were a total 80 passes + the clean up passes.
2) The panel was between the table and the bit. The table is very smooth, well waxed and slick.
3) Th OPR table simply sets on the saw table with
SS "T" nuts to fix the two tables. When I unpacked the OPR - "T" nuts were missing. A quick call got them shipped to me at no charge.
In the meantime I clamped the OPR table to the saw table. Noticed that clamping will offer some new possibilities for table placement. BTW "T" nuts were received in 6 or 7 days.
4) I don't think you can use the OPR table with an under table router because of the top-side cut out to accept the two inserts included with the OPR. If you now have a SS router system such as (555413) or (555414) then I suppose you can use that table for both purposes. Don't have experience here, but included with the OPR instructions was a 4 page instruction showing how to convert two tables to the OPR router fence. These instructions were directed to "Routing System (555413)" and "The Free Standing Router Table (555414)" Also included in this paper are instructions for measuring and installing threaded inserts for the OPR fence in the older plywood tables.
5) The OPR inserts are 4" diameter. If you have, or can make an insert recess that is 4" in diameter (round), -- then the answer is YES
6) Mortising is a breeze with a normal SS in Horizontal position. (Think I got this hint from erlicson) I had always done mortising with a router bit on the SS in vertical mode. Even that works O.K. It'll be better yet with the OPR.
7) Tenons and half laps should be a snap in both horizontal and vertical modes. I think the key here is the fence and hold downs. (or use of a sled).
