A joinery jig that works well both right-side-up, and also upside-down, is a huge plus. I have already shown the Leigh R9Plus “right-side-up”. It worked great. But I was curious about the upside-down configuration, on the router table. I was in for a surprise, as it is a breeze to use this way, although it took me a bit to get used to feeding the jig into the router bit. How is that for a total newbie?
A huge plus of doing the joinery using this jig on the router table is dust collection (DC). I was pleasantly surprised, as nearly 100% of the dust and chips were taken by the DC system I have on the old router table. I just wish I could use this jig on the Laguna cast iron router table. But, without the proper insert, it is impossible to use the eBush designed to work with the R9Plus. I will follow up with the people at Laguna Tools, to see if it is possible to machine some inserts to use on their router table, and I will my readers know.
Here we go: the R9Plus on the router table, as I get to know it in this configuration. What do you think?
My personal opinion: This will be terrific, especially for very large work pieces, as it becomes trivial to make sure the work piece IS flush under the template. Or, should that be ON the template?
Stability: Used upside-down, the wide template rides on the surface of the router table, stabilizing the work piece. I must try this with a very large and wide board. I will report results.
I love it!
Disclosure: Leigh sends me jigs on occasion, for testing and evaluation.
