I’m in the process of replacing the table on my Rockwell Super 990 RAS. My original top, which is 50 years old was made with very tight grained Douglas Fir that was glued up in 3/4” wide strips. (at some point my father added a 3/8” MDF top) I bought some 11” wide 5/4 QS Poplar and plan on using that as the underlayment for the table. I only have a 6” jointer, so I’ll rip the boards in half and get them all dimensioned for glue up. My question to you guys is,

Should I leave the QS poplar at 5” and do the glue up from that or would I get a more stable top by ripping the boards down to and inch or so and then doing the glue up? Would it even matter since I’m using quarter sawn poplar?

I’m kind of thinking on the same level as you Scott. Since it is quartersawn the movement will be minimal. 5 inches isn’t really that wide so I think it will work just fine. Cutting you your strips down to 1 inch or so may be more work that you don’t necessarily need to do.

I recently inherited an old Delta Milwaukee 10” RAS and I’m going to glue up two 3/4” plywood sheets (either Baltic birch or oak veneered) to for a 1 1/2” top and screw or staple a sheet of 1/8” tempered Masonite to the top as the sacrificial surface. The rear stop will be screwed down and made from some kind of hardwood, probably whatever I have laying around.

Have your say...
