Thanks all, good to confirm I wasn't missing something there.
Point also heard about the shopping list. I already noticed they call for a 2" thick piece (two of them, actually) for making parts H, I, J, K, & M, none of which are thicker than 5/8". Guess I shouldn't expect too much from plans which were created as advertising for finishing products :)
While I'm here, could anybody share an opinion about their method for making the mortises in the legs? They recommend using a table router, which works easily for half the cuts (where the cut begins by going through the top face of the leg). But for the other half, this requires starting the cut by plunging the work into the bit, then pushing through and exiting the top face of the leg, as described in step 11 and shown in fig 4.
That plunge technique seems a bit dodgy on a table router- I can see all kind of things going wrong with it. The alternatives are a lot more hassle (drilling and chiseling, or making a jig and using a plunge router), but probably safer.
Call me CJ :)
