CSEMARTIN Posted July 27, 2010 Author Share Posted July 27, 2010 Again, what's wrong with the factory equipped lead screws? Exactly!!!!! I came to my senses yesterday. After several hours of trying to get the y-axis ballscrew to "center" itself, I made the decision to ditch the ballscrews. I spoke with the company that sold them to me and they are going to take them back and refund my money. I feel so relieved. I can't wait to package everything up and ship them out of here. Thanks guys for you help. The machine is now under power and fully assembled. I still need to install the DRO, but that can wait until tomorrow. I'm beat.

CSEMARTIN Posted August 24, 2010 Author Share Posted August 24, 2010 Although assembled, I'm still fighting with the x-axis. It's unusually tight and I can't figure out why. It wasn't like this before. The y-axis is beautiful. Any ideas? I've taken the table off and adjusted the screw that adjusts for backlash/tightness on the lead srew. I've also tried tweaking the crossfeed assembly brackets, and I've made sure to lubricate everything really well. Should I try adjusting the housing that holds everything to the saddle?

Aircooled6racer Posted August 24, 2010 Share Posted August 24, 2010 Hello: I would adjust the housing for the leedscrew nut. Also check that you have the gib in correctly etc. My mill is getting a little closer to completion as well. I still have more painting to do and the cleaning part. Thanks, Eric Link to comment Share on other sites More sharing options...
mike cyrwus Posted August 24, 2010 Share Posted August 24, 2010 I was hoping youd put the ball lead screws in and rave about it. I cant complain with how mine feeds as-is, though. Good fine-motor movement practice for me, thats all it is. Link to comment Share on other sites More sharing options...
jgun Posted August 25, 2010 Share Posted August 25, 2010 I had forgotten about this thread, Since my last post, I've dismantled mine moved it from the warehouse to my house (thanks for the advice about renting the liftgate truck) got it onto the slab in the back yard, reassembled it, and built the shed to house it without a single other persons help. I still have to shingle and side the outside of the shed but I'm hoping to have the phase converter this week and be able to fire it up. I'm trying to add pics but so far no luck Link to comment Share on other sites More sharing options...
CSEMARTIN Posted August 26, 2010 Author Share Posted August 26, 2010 Hello: I would adjust the housing for the leedscrew nut. I was afraid someone would say that. I wish there was a way to do that without having to take the table off first. I was hoping youd put the ball lead screws in and rave about it. Me too. thanks for the advice about renting the liftgate truck You're quite welcome. Link to comment Share on other sites More sharing options...
CSEMARTIN Posted September 5, 2010 Author Share Posted September 5, 2010 Hello: I would adjust the housing for the leedscrew nut. Also check that you have the gib in correctly etc. I've had the table off four times today to adjust the housing, and I still can't get the x-axis to move freely. I've also made sure the gib is adjusted correctly. I'm at a complete loss. Any other ideas? Link to comment Share on other sites More sharing options...

m134b Posted September 6, 2010 Share Posted September 6, 2010 You may have a small piece of garbage in the leadscrew nut. While you have the table off, I'd check and make sure the screw itself isn't slightly tweaked, that can cause a lot of headaches! If that's not it.... I'll grab a chair in the same boat with you!

CSEMARTIN Posted September 6, 2010 Author Share Posted September 6, 2010 I am going to take the housing out and clean everything down to bare metal. I think you might be right Ken. I'll bet I got something in where it's not supposed to be. Link to comment Share on other sites More sharing options...
CSEMARTIN Posted September 6, 2010 Author Share Posted September 6, 2010 You were right Ken. Thanks a million. There is a brass bushing inside that housing. I took it out and soaked it in Naptha, took a brush to it, then blew everything out. I relubricated everything, put her back together, and now the x-axis is very smooth. Maybe I'll finally get the DRO on one of these days. Link to comment Share on other sites More sharing options...

A Bridgeport is a kick in the pants to have. All of a sudden you can turn good parts into junk. Tooling it up is a never ending trip.

If you know what your looking for and can separate the wheat from the chafe keep an eye out in Craigs List (tools). I've found some nice stuff there. Lots of junk too.

jgun Posted October 2, 2010 Share Posted October 2, 2010 Fireant, As per my PM, the Workshop (shed) is 10'x16' on a cement slab. If I can fix the problem that is keeping me from posting pics, I'll post a couople of under construction shots. Now I need to find a lathe. The only problem I have to date is that I keep going through phase converters, I'm on my third one so far. I also think that the X and Y axis have more backlash than I'd like, I tried to adjust them with no luck. I may replace the feed nuts down the road, but right now I'm having too much fun using the thing and don't want to take it apart. Thanks to all for good wishes.

z40acp Posted October 2, 2010 Share Posted October 2, 2010 jgun, forget the phase converters. Purchase an ac frequency drive. Put 220 single phase in and get 220 three phase out. You have to get the correct size and not all of them are single to three phase. Look at Automation Direct's website. Link to comment Share on other sites More sharing options...
jgun Posted October 2, 2010 Share Posted October 2, 2010 Z40ACP, Thanks for your advice, I'm not familiar with AC frequency drives but plan to look into it. Offhand can you tell me ballpark what they go for? Link to comment Share on other sites More sharing options...
m134b Posted October 3, 2010 Share Posted October 3, 2010 I have personally never had much luck with frequency drives.... rotary phase converter has worked for me for quite some time. 'course, I built each to suit its application. There are several decent online tutorials for DIY phase converters, but they elude me at the moment. I'll post back if I can locate them.
