good job. You've got some beefy looking linear rails.
Jason
yes they are big no flex there i wanted to build a good strong machine ,im going to be using it a lot
Looks great, what kind of spindle are you going to run on that?
i was planning on a Hitachi M12VC they seem to be very precise and most of all SHHHHH quiet
you are not kidding there i dont know why porter and cable cost so much money my lord they must be making money like the oil tycoons.:rainfro: anyway there easy to rebuild too!!
I doubt it, they are pretty reasonable for what they are. And in my experience porter cable products in general are very well made and constructed of solid materials. Plus their support is pretty awesome. I wouldn't ever use the hitachi for anything more than a spindle, it's got a pretty cheap base, but none the less makes a pretty damn good spindle!
Seems like you're taking a low-hassle middle-road EXPENSE VS TIME. Kinda what I'm thinking of doing. The picture has a perspective that makes me want to confirm that your WORKING width is a clear 37", is that right?
If so, this is just about perfect since my desire is 32x48.
Any chance you'll make some crude drawings and materials list and sources?
Can you translate that 3 weeks into actual hours?
Any kind of exotic shop machines you're using that lowers your hours?
Any cost forecasts yet?
yes its 36 X 48 usable here is a breakdown of the parts

I have put about 40 hrs into it at the pic you were looking at.
I am lucky to have a mill and lathe to cut the parts.
should be a very precise machine when im done. ill post a couple cuts in about two to three weeks depending on how things go.
i just finished mounting two of the motors i will post another pic on sun.:wave:
can anyone help me find a router holder for a bosch rotozip rz5 model, all the ones on ebay are for porter cable.

ive tried them I cant get a response
mar999,
Itchin for the pics!
This is a twin drive on the X-axis, right?
yes it is im just getting the last x axis motor mounted now ill havem up soon
Hi mar999,
I wondered if you were worried about flexing in your 37" axis. I could be wrong, but that seems like a large unsupported span, especially for 3/4" rails. I'd hate to see it disappoint you later considering the great work and money you've put in so far. Wish I had the funds for some of those components.

Regarding the Keling hardware. What combo did you buy? Stepper torque and drivers are of interest to me. Did you get the package?
Oh and what TPI is your leadscrews?
