Took me over 20 years, but I did find an old Griggio, from the early 80's, and snapped it up, together with the rest of the tools and wood, all from an estate. About $4500 new, although the Invicta is about $2700 if I recall correctly. I first saw a slot mortiser, demo'd by Alphonse Mattia, in about 1980, and since then looked for one on the used market as they are spendy. I talked to him once about the idea, and he is a knowledgable and inventive fellow. How stable and accurate it is in use is not known to me.Ī second option if you want to build is that there is a fellow from upstate NY on ebay who sells good quality linear bearings and stainless rods at very favorable prices in diffrenct sizes, and with them you might be able to cabbage one together, using a router for the power.

The chuck is apparently not designed to withstand the lateral force of the stock movement, but users have not reported problems, to my knowledge.
