« Part 7: Sketchup Challenge Part 8 of Sketchup Models series no next part

I’ve started a rough sketchup of a homemade version of the Bridge City Kerfmaker that I plan to build. You can get the sketchup “here”. (link removed… Read the thread for details) If anyone wants to improve this then please do and let us all know where we can get it.

wasn’t there a big fuss a while back about the Kerfmaker being posted on LJ? I think the owner himself even came on to comment about it, and ended up offering the scale drawings for a $10 donation to a charity.

i’ve tried reading about these before. I still don’t understand what they are used for. I think it’s time to do some more research.

nice job. but as Interpim stated – there was a bit fuss about making this patent-pending design available for free. although it’s only pending, Bridge City didn’t like the idea very much, and I can see their point – especially since you even refer to them by name and model in the OP ;)

ouch! Thanks for the heads up guys. I don’t recall ever reading the thread that you’re talking about but I do not doubt your word on it. I’ve seen several home made copies of commercially available items on lumberjocks before so I naively thought as long as I wasn’t trying to profit from it that it was ok. I’m still not convinced that there is any law broken from providing a model but as a courtesy to the designer, if he doesn’t want it shared then I guess we should respect that.

OK that thread. I found it. Its very long. Bridge City does have some kind of personal problem with sharing drawings.

I just made this thing last night. I’ll try it out and post some picks. It was actually quite easy to build it. I picked up the knurled nut from Lowes and a couple bolts for under $3 total and the walnut I used was scrap. Its a bit rough though. I’ll make a nice one soon.

First its not flat. it looks exactly like this one.

At my Lowes in the nuts,bolts and screws isle there is a small section of bins. Its where they keep T-nuts and odd things. There was like this one knurled nut that they carried. It came in a two pack in a little plastic bag. Its threaded for 10-32 so I also grabbed some 3 inch 10-32 screws and cut them to length with my dremel after I installed them.

I tapped the walnut for the screws. Made sure they fit good. Put a tiny dab of gorilla glue on the threads and screwed em into the threaded hole. I’ll try to get pics up tonight but… this first one is fairly ugly. I just pounded the mortises out with chisels and didn’t use a router at all. Quick and dirty was my goal this time around. I wasn’t sure about tapping 10-32 in wood and wanted to see how this would go together. I plan to make a nice one when I get around to it.

Well the hardware works fine and tapping threads on walnut worked well too. With that said I have to admit that my craftsmanship on this was more like crapsmanship. The end product produced poor results. The design is a faithful copy of a proven concept so all I have to do now is a better job making it.
