Started construction on my router today, it's going to be a stretch JGRO design, stock x and z axis and extended y with 60" gas pipes. Forgot one piece, but got the rest cut to size, going to start routing out the grooves tomorrow. Hopefully will have time to drill the necessary holes and start assembling tomorrow too, if I remember I'll take my camera and snap some pictures.
Other hardware includes:
276 oz/in motors from automation direct
a3977 drivers from pminmo.com
1/2x10 acme drive screws
old printer power supply with 2 24v 10A+ rails until i can build something else
The only thing I haven't gotten yet is a "good" spindle. I want to use it on future machines as well (larger/faster), so I want a variable speed router to start, no dremels, rotozips, or laminate trimmers. Anyone care to throw out some ideas for a good router, something under $300.
Check out the Hitachi M12VC. Variable speed and only $114 + tax at lowes. Comes with 1/2" and 1/4" collets.

Got all my slots made and packed everything back home. Have to clear out some room and make a workbench to start drilling and assembling. I think I am going to just use screws for assembly, I am planning on rebuilding or building new as soon as it cuts so I'm not too worried about taking it apart and putting it back together much, and will be predrilling all holes to help stop splitting. I have the taps and such to do it proper, but I want to get this thing together before I get sidetracked for months again.
I really like that router, and the price is perfect
Haven't built up the motivation yet to start marking my bearing carriers off, so I figured I post up some images too see if that will help kick start me this weekend. First two are all the main pieces for my machine, and the last is my #1 project after getting my machine working good, building a new box for my ugly projector. Sure do wish joe would pop his head in... (hint hint haas gcode hint hint)
That is quite a pile of parts you've got there. Seems like a lot of the hard work is done what with all the cutting and routing. Looks good so far. Keep it up. Looking forward to seeing how the stretch to 60" is going to come out. I expect you might find some sagging with that length. What diameter pipe have you decided on?
Just let me know what ya need, and On my 2nd machine i made it with 3/4"x36" pipes on the Y axis and 1"x60" pipes on the x axis.Originally Posted by ShayArnett

I also went with 1" for the 60" length and 3/4" for the others, have to make some minor adjustments due to this, but I'm going to assemble starting with z so I can make sure I get my pipe placements in the right place.
Joe did you experience any sag with the longer pipes on your second machine? Obviously it didnt really affect your cutting, model 2006 came out great
Made a trip to the flea market and picked up 7 lbs of fasteners for $11. More than enough for putting this thing together. The baby is asleep in the room beside my "shop" so I'm afraid to go in clanking around too much. Hopefully I can make some quick progress today after she wakes up, I would like to get my z axis finished up so I can play around with it and a drill.
Few pictures of z progress, and some of my other tools
Didn't get much done... spent too much time measuring and marking and that all went to crap when I got behind the wheel of the drill
The micro is going to be cnc also, I am actually still debating what to use my electronics on LOL When I don't have lots of time to work on the router I'm making motor mounts and bearing blocks for it, prolly have it ready to cnc before the router is finished.
No on the mdf it cut good for me, like you said I cut the new machine on it..Joe did you experience any sag with the longer pipes on your second machine? Obviously it didnt really affect your cutting, model 2006 came out great
I had a major breakthrough tonight!!! no but really... had 30 minutes between staying late at work and getting called back in so I drilled out and screwed together the rest of the z-axis, gotta do rail adjusters and stepper mounts and it will be ready to test.
Just be happy you aren't a stepper motor and have to stare at big hunks of mdf and aluminum flying at you at 100ipm
Also have to throw in a couple pics of my little helper, programmin a part on the pc LOL.
