Re: Felder Silent Power Dado 6.3-20mm #forsale
¿ªÔÆÌåÓýMike, there are lots of other adjustable groovers similar to the Felder dado cutter. ?However, they are geared for use on a shaper or tenoning machine, and thus are designed with different constraints in mind. ?One example might be the Whitehill 10-19mm adjustable groover you can find here for about US$300 plus shipping: ?It¡¯s available with a 30mm bore, in various groove cutting min/max widths: Like a lot of other indexable groovers, this one is 160mm, sized so that it can project to maximum depth of cut (¡°Tmax¡±) through the window on a smaller shaper hood. ?When installed on on a K700, the maximum depth of cut will be limited. ?The K700 has a max depth of cut of 104mm with a 315mm blade, which would put a 160mm cutter at ~26mm above the top of the machine when fully elevated. ?That cutting depth may be further restricted by the Tmax dimension of the Whitehill grover (see photo above) which they don¡¯t specify. However, ?the real issue with these types of cutters is the thickness of the hub as shown below. ?This particular cutter appears to have a hub that is significantly thicker than the cutting blade itself: The arbor length on the K700 saw is limited, and the Felder dado cutter is specifically designed with minimal thickness hubs so that even when fully spaced apart, the cutter still fits on the saw arbor with the end-cap engaged. ? The hub thickness of the Felder 12-20mm dado cutter is 15.4mm with no shims installed, so at it¡¯s maximum groove cutting spec of 20mm, the hub thickness grows to 23.4mm. ?So before looking at other adjustable width groovers, consider the ~23.4mm hub thickness as the limit of what your saw arbor can tolerate. ?There ?may be other impingements with the sliding table or cast iron top depending on the hub configuration of the cutter you¡¯re considering. ?See below: Of course, Whitehill isn¡¯t the only adjustable groover manufacturer. ? Rangate makes adjustable groovers in 160 and 225mm diameters, but the groove widths achievable with them aren¡¯t ideal for use on dado cutting for conventional 3/4¡± or 18mm thick plywood. ?Amana makes adjustable groovers also, but the groove width range isn¡¯t ideal. ?And of course, there is the hub thickness issue to figure out.
