Heres a few photos of a router I threw together the last two weekends. I needed a router that could do bigger parts than my jgro router could for my V2 router in my build log on here, guess that makes this one V1.5 . One project is a race car bed for my step son, it was begging for a set of cnc cut wheels . I went with a moving table design this time and besides it taking up alot of extra space I really like the way it runs so far. One word of advice to all using all thread rod for lead screws, get a threading die! I picked one up and ran it over the rod with a drill ste at slow speed and sprayed down the rod with wd-40. The amound of shavings that came off were AMAZING at one point I had a 4" long ribbon of metel come out of the die. My old router had a few spots along the way that would bind up. I went thru three different lead screws and still ended up with problems, had I ran a die over it I bet I would'nt have had su8ch a problem. Anyway here are some pics.

Hi,

Very insteresting design... Am I mistaken or the "out of center" leadscrew is because you are "restraining" horizontally on just one side ?? That way it will never bind, right ?

Is the machine running yet ? Can you get some pictures of how precisely it can make cuts ? It seems so much easier to make than most designs so far...And it maybe more than enough for wood and plastics work.

Best regards,
Alexandre Guimaraes

Nice work, Darren! Good improv...!!

I offset the leadscrew simply because I thought it might work better closer to the side that it is restrained on, does it? so far so good.
Here are a few pics I took tonight. All the cutting went great. The pics are of some wheels i'm doing for a race car bed for my step son who will be 6 on the 6th.

Please, how did you clamp the raw material on machine in order to be machined?

[CNC Darren]

if you look closely there are two drywall screws holding it down to the table. Kinda of a cheap way of doing it but it works well for me.

[zoltan]

Yeah. Sorry. I have seen it now.

Very nice machine! I have a question for you... how did you build the frame for the table? How did you make sure that welding the pieces together didn't bring them out of alignment/level?

[CNCRob]

Very Nice!

What feedrate do you run normally?

[CNC Darren]

ignatz: the frame was something I had laying around and just happen to have the right dimentions for what I needed.

Redline: The feedrate for cutting the wheels was 25ipm. While i was tweaking the machine the first night I had the rapids as high as 80ipm. I'm using a HobbyCNC 4 axis chopper board and 118 oz/in steppers
