A few weeks ago, paid 600 bucks including travel fee for a 3x4 to grade a. Why not call around and get quotes? I had em check a bunch of stuff while they were here too.
I have found what I think is maybe a typo in the manual, and I'm not sure if anyone here knows for sure how to do this... When setting the upper limit and home for the quill, the manual states to move it to the uppermost position by hand, then rotate the pulley one revolution. they state this...
Richard, what you are saying about wear is matching what I have found in my measurement. It's a bit low in the middle.
Thanks for sharing your knowledge about turcite shaping.
For anyone who may follow this thread in the future, I measured flatness on my x axis ways and found it to be within .0005" over any 36" span everywhere except for two spots where it is slightly over .0005. There is some wear, and it is slightly bowed with the center being low. I just had my...
I would get an indicator and a pry bar and see if you can find any free motion in anything. I've seen loose knee gibs cause a similar issue on a bridgeport cnc.
I have no doubt about the experience and knowledge that Richard would provide, and if this was a machine worth the cost I would go for it. As much as I would love to take on the learning experience from a pro, I can't justify that kind of cost to learn a skill that ultimately is unlikely to...
Richard, thanks for the reply. I am leaning towards using this machine for a while and then replacing it with something better/faster. I suspect it will hold a good enough tolerance for my immediate needs.
I have met him a couple times, and actually I think I am probably going to pay him to machine the new turcite once I have it installed since he is not too far away for a day trip.
Tell that to the shop up the road who had the turcite fall out of their Doosan. Any machine can be susceptible to damage if there is an isse with oil or lubrication, whether it be by negligence, failure, or poor design.

I think any of these in this price range are going to have a good chance of having similar issues and will have a lot of age and wear. I do know of one that going to be for sale that is in very good condition with 5th axis + all the bells and whistles, but the price is reflective of...
You're not wrong, I should probably just do the bare minimum to get it running and replace it with something much better when I can. To be honest I have always kind of wanted to try my hand at scraping and this would be really more to satisfy that intellectual curiosity and challenge.
Good point on maintenance. People should treat things properly. I got the machine for next to nothing, and kind of expected to be doing turcite so I'm not complaining.
Hi all,
Looking for opinions on how much I should try to fix on my new to me 1989 4020. I have the machine sheet metal off, and mostly apart, so it is a good time to go through everything and get it up to par. I would not be afraid to go at the ways with a grinder, as others have done, to make...
Business has been good and I have been working nearly 7 days a week, so I really haven't made much progress on this project until recently. I decided to 3d print these parts instead of machining to work through any issues first. Even with making this print on very strong settings it is flimsy...
