First post on this website; looking for some help/advice on using an old PowrKraft radial arm saw to do some routing with. The model # of the RAS isTPC-2610C and it has an aux. spindle turning at 20,000 rpm. To mount the router bit you need a collet with part #84-2613, which I don't have. Really odd-ball thread: 15/32-20 (!!??) So, for my first post, two questions: (1) does anybody out there have such an item they no longer need, or any suggestions about where to obtain one? (2) has anyone had experience with routing using a RAS? Comments on advantadges/disadvantages solicited. Hope I get some responses from the membership; I'm new not only to the forum but to the "art" of routing although I have ruined a few pieces of wood with my efforts. tom in vermont
