When do you intall the end graft/wedge?

[Woodyok]

Very nice Dave. I have always struggled with the end graft. I try it on my next project.
How do you drill those nice square holes in the MDF?

[Dave Bagwill]

I should post another vid to show that advanced technique - basically, I drill a round hole thru the mdf the same size as the screw I will be using, put the screw through the hole, then pound the crap out of it so that the square thingie on the screw makes its own little square hole.

[Woodyok]

Ahh. so you used a Luthier fine adjustment hammer.

Stewmac, $110.00 :-)

Is that the same tool that Chevy mechanics refer to as a Ford Wrench? I think I have one.

[Dave Bagwill]

Same tool, you got it.

You can use a nut on the bolt end to tighten it and draw the square thingy into the MDF thus saving you Ford Wrench or is it a Chevy wrench, I always get them miped ux.
