Half Lap Joints

Pages: (1/2) > >>

From searching the web it seems like a common method of making half lap joints is to make a bunch of kerf cuts with a circular saw and then chisel away the remaining wood (http://doityourself.com/power/quickhalflapjoints.htm).  This seems like it might chip the wood causing a sloppy join in the end.  Has anyone tried this method ?  I was think of just using a router to router out the entire chunk of wood but it seems like that might take a while.

bbal,

if done properly this will hold well.  The trick is to chisel evenly then sand ever so slighly.  Then, you can connect using your favorite joint compound/glue.  

Ideally you can use a radial arm saw that can make cuts adjacent to each other.  This way you don't have to chisel anything as the blade will cut it all away.   I'm not sure I would suggest doing this with a handheld circular saw, though as the saw may jump.  I could be wrong on this, but do so at your own risk as I've only done this using my radial arm saw.

You can also use your router but you would have to support the router so that the cuts would be even so a jig is probably called for.  Also the lap joint would probably be made in several passes with the depth being increased with each pass.   A nice clean joint could be done with a router but only if a proper supporting jig was fabricated.  Really not a hard job.

Thanks for the input, I am going to experiment with both methods.  I was talking to someone earlier who said the saw/chisel method works well if you have a pretty sharp chisel.  I still think I'm leaning towards the router method but we'll see how the experiments go :)

I know you didn't spacificly ask about it, another method you might think about is using a table saw (if you have access to one) using a dato blade, very fast and works like a champ...but the blade isn't cheap.

just a thought
