Milling out door hinges with special drill

[bonpon]

Hi all,

I came across the attached image by accident.

Apparently, it solved my problem! See, in this image, it looks like the machine is routing out a door panel and drill holes for the door hinge. I have been thinking a lot of how to do this. First, I though I have to stand the on the edge and manually route it out using regular router with a template. But then I saw this picture, and I was OMG – YES! that's what I am looking for.

So does anyone know what company make this 90 degrees drill???

Thanks!

Bonpon

AWESOME. I thank you sir! Last question: Does MasterCAM support this tools?

Dang, these are expensive stuff, at least $7000 each!

Hi Bonpon,
I'm not an out and out woodworker but I have prepared and fitted plenty of doors. Your choices are (1) route the hinge rebates using the standard jig. I hate this method because one of the hinges ends up taking all the door weight. (standard handheld router)
(2) make a jig yourself that fits all of your doors and that routes all of your rebates at the one time instead of moving the jig to the next hinge height like you have to do with the standard jigs (standard handheld router).
(3) you haven't told us anything about your machine or your skills but let's assume that (a) your machine is big enough to do doors and (b) like most others working with wood, nearly all your work is done on the flat plane and (c) the only time you'd want to work on the vertical plane is for doing hinge rebates. If that's the case and if it were my machine I would make a holding fixture off to one side of the machine (in line with the X axis, i.e. the long side) with which to hold a door in the vertical position. Next you fit an el cheapo secondary router or spindle to hang off the gantry directly over the center line of the door edge. Router or spindle is hung off an el cheapo Z axis using a pneumatic cylinder where it is either up or down (using limit switches and height adjusting threaded rod). Ger21 has studied the posibility of fitting a secondary Z axis (although in a different format) using Mach3 and it is possible. You would have to use the same tooling diameter as the diameter of the hinge but at least you would be able to do all three or four hinges correctly spaced and at once. Because you wouldn't have Y axis movement for this motor you would still have to chisel out the part of the hinge where it exits the door and goes to the hinge pivot point. Crude but I'm sure it would work.
p.s. Rebate = rabbitt, rabitt or however you spell it.
p.s. How's the weather in DF at this time of year
EDIT. Don't know how your machine is but have a look at this normal looking MDF built cnc router: http://www.cnczone.com/gallery/showp...5/limit/recent It sure wouldn't be too hard to design a machine where the Y axis cross slide is wider than the table. This would eliminate the need for the secondary router/spindle motor and z axis and would still have the full movement in all directions including while doing door hinges off the edge of the table. Certainly do-able if you ask me...

Thanks for a detailed reply. I will consider that.

Wow Skippy!

As long as I've been reading this forum, I can't recall having come across this concept! I'll definitely be looking at adding this to my future effort.

Thanks!
