I am looking at a shaper, as I have been unhappy with my router table's performance when it comes to larger profile mouldings. I find the lack of mass in the router table helps the router 'chatter' and make bumpy/wavey cuts. I have my current router table (jessem mast'r lift) in the extension wing of my sawstop. My main complaint is the difficulty of having consistent depth of cutting height when doing raised panel doors on the rails and stiles, and on larger profiles, the router cant keep up with the cut, or (as stated) the lack of mass/heft in the table causing the bit/wood to not run smoothly and the slight chatter in the bit. (kind of hard to explain).
Those are the main reasons I would consider a shaper. The idea of a shaper with router bit adapters for 1/2" router bits is nice, because I would probably still use the router table for the smaller profiles, but for larger profiles the shaper, which would also address my concern of lower RPM's on the shaper being an issue, as the larger profiles I would make on the shaper wouldn't need the higher RPM's.
I am curious for those with both if my reasons for considering a shaper align with the benefits I would receive from investing in one.
Thanks in advance.
