i contacted steel city to inquire as to thier shaper #48120, the catalog states "includes 3/4 & 1 inch spindles and 1/4 & 1/2 ROUTER collet standard" i asked if the shaper , since it has the ability to use router blades, could be used as a router table, the answer was YES ! the only referrence i was able to find was fine woodworking #66 page 16,there is an equation i really dont understand,the two people in my area of brooklyn said they didn't have a shaper due to the cost of the blades, therefore had never tried it or didn't know. comments please.
