Awesome! 1.75" extra is huge. I've got to move that up on my list of things to do. With my current x-axis stepper mount there is going to be interference when the table tries to use up that extra travel, so I'll have to rethink my current setup (already have some ideas). Its nice you have that extra machine to do the milling on your base. I'm going to have to do mine with a sawzall or drill/chisel it out and it will look like crap.
+russtuff Yeah its definitely gonna be a worthwhile mod. If you want it pretty looking you can always send the base to me and I'll extend the slot for you, I don't know what shipping would cost, but those flat rate boxes are pretty reasonable. Obviously no charge on my end, your videos alone have me in debt to you! Love your videos!
ElementalMaker That is very generous. I haven't really looked at it, but if possible I would like to do it without having to take the column/table off the mill. I need to spend some staring at it, but nothing gets done until this stupid lathe if finished :/ If it looks like it all has to come apart then I may take you up on it. I have loads of flat rate boxes already sitting around :) I'm glad the videos have been a help!
That wasn't terribly difficult. Kinda weird that the column screws have 3/8" hex sockets, rather than something metric like all the other fasteners. Just watch out for the little keys falling out when you remove the handwheels.
This is a great video. I was just wondering by extending the y axis 1.75 to 2.0 inches will I have to get longer ball screws on my G0704 mill ? Great work.
No, total length remains the same and is limited by Z column. Ball screw on Y is not supported on far end. This mods allows to nut to go closer to motor. This mill has spindle not in center for Y axis when in middle travel.
Hello! With great interest I watch your work. Just plan to convert such a milling machine. I have a couple of questions. You do not scraping or grinding dovetails and wedges? Are you planning to do for the lubrication channels dovetails and ball screws? Thanks in advance for your answers. P.S. Sorry for my English.
+Custom Cycle Your English is great! The mill is supposedly already hand scraped for both fit and oil retention. I may do dedicated oil lines / channels in the future. I've seen others do that on the forums, and it is quite a nice system.
+ElementalMaker Thank you for your immediate reply! If you mean scraping the factory, it is a mere formality. The contact surface and the whole geometry as a whole simply awful :( Made in China ... However, fear of doing worse stops me to take up the scraper. Once again thank you very much for your reply! I look forward to the next series. Good luck!
+Custom Cycle Yes im with you there, I intend to learn how to scrape and eventually scrape the ways and gibs to get a very precise machine, however at this point I believe I will use the machine as is. You are certainly correct that the factory "scraping" is somewhat petty
