Dear Kim,First, I would like to say that a radial match with a short grain boarder is no easy feat, especiallynot the first time around. It takes one or two to get the hang of it, so I would say your righton track if its your first one.Surely, having only 7 pieces of Koa makes it hard to get the joints just right especially if thegrain is highly figured when you move down the sheet.A few tips, first I have a set of plexiglass wedges for doing radial layout work. One that is aslice of a 8 way match, also a 10, 12, 16 and 24 way match. Next, I always stack all my pieces together in one sandwich and cut them all at once, carefully lining up the grain in eachpiece to the next one so the grain pattern will match at all the joints after trimming. Also, lay up each halfat a time, allowing the pieces of veneer at the center line to run long. When the two halvesare taped up, I lay them carefully on top of each other, trim them together and then tapethe two halves, making a complete circle.One thing about your Koa joints not lining up with the crotch joints. I know you were short onkoa but I would have had 4 pieces of koa in each section that would have made the centerveneer and short grain boarder joints line up.I suggest doing a couple more with some inexpensive veneer to get the subtle points of radial matching down and then go to some fancy veneers.Your also welcome to call me at 207-725-0935 anytime if you want to talk further on this one.SincerelyDarryl Keil: Hi again,: We layed out the following table and had a couple of problems that I'd : like to ask you about. The interior was a four way match of walnut : crotch. The edging was Koa and book matched around. We hope to : "waterfall" over the edge of the table but haven't yet done that work : and might not bother given the problems outlined below. : : layout" WIDTH=587 HEIGHT=359>: Unfortunately we only had 7 leaves of Koa and so due to the width had : to skip down (is there a technical term for this) the leaf at leaves : 6 and 7 and then return back to leaf 1 to give us a total of 14 : pieces. The match was pretty close when we looked at it so we weren't : concerned. However 1) our cutting was not very accurate and so the : joint on the interior ended up not matching the opposite joint on the : exterior ring. 2) Our book matching was not very good. Some matches : are okay others are pretty far off - not just the matches on the 6-6 : and 7-7 leaves either. : Is there a procedure to layout and cut these joints accurately? E.g., : should we be printing out a full size pattern and working from that : (we printed out a quarter of the table this time.) Given the : limitation of number of leaves of Koa, did I do the layout correctly? : The table looks okay. The colors are great but the quality is : lacking: I.e. I can't really sell it.: I think this is partly a personnel problem, but I'd like to have : enough information to be able to instruct "my expert" on how to do the : work accurately. Any help or insight would be much appreciated.: Kim Carleton : Graves: Carleton : Woodworking
