Joes CNC Model 2006 in Vancouver, Wa

[acondit]

Hey Nick,

No, I haven't tried putting the gantry on the x rails yet. I guess I could try fitting that too. I'll just have to take it apart when I get the hdpa leadnut holders for the 1/2-8 2starts. I'm going to move to the electronics till I find someone to cut me the hdpa holders for the dumpstercnc stuff I have. This is a time where it would be nice to have another cnc machine handy. I thought I saw Joe had publish the cut files for them. It's also a good time for me to go back thru all the posts and see if missed anything. I'm also starting to play around with the different cad/cam software packages out there looking for what will work for me.

If anyone can help me out by cutting the pieces I need, please let me know. I have some extra parts and a few good computers to trade with.

Flyon

Flyon,

I would be happy to help out.

Alan,

Maybe I can send you the three hdpa pieces which need the "square" pocket cut instead of the hexagon pocket which is there now. Reminds of the square peg in a round hole problem. I'll try and look tonight for the code/dimesons to cut the pieces. Or if that a bad solution, I can find some blank hdpa and we can cut the pieces from scratch. Let me know what you think.

Thanks alot,
Flyon

Flyon,

You aren't going to use the stock pieces anyway, so why don't you send them to me and I'll see if I can cut the square pockets in them. I should be able to do that in the mill. If the doesn't work then we can make some new ones. Measure your Dumpster nuts and send me the dimensions with the original parts.

I looked at Joes drawings and I don't see how the dumpster nuts are help in place. Are there some additional holes that need to be drilled for screws that I don't see?

Yes, i press fit the dumpster nuts into the pocket then use a drill press and drill the 4 holes, then tap the dumpster nut and HDPE at the same time and install the screw. it is very easy to tap.

hope that helps.

Joe,

Thanks.

Flyon,

If you send me a 5" length of your threaded rod with the pieces, I'll make a tap from it for you as well.

Alan,

I just mailed out the hdpa pieces to you this morning. I also included the leadnut stuff from dumpstercnc for test fitting and a prepaid return envelope. Thanks again for helping me out.

I haven't cut the 1/2-8 2start for the y and z axis yet. I did some test fitting but that all. I can cut them tonight and send you the extra pieces tomorrow. I'll do some guessdamating on the y and z lengths. I just don't wanta come up short.

I've been cutting stuff using a 8" cutting blade on my table saw. It works really nice for cutting the alumium to size and grinding the flats too. It also worked to cut the drilling rods, but I saw it left some discoloration on the rods, probably from heat. I'm sure it will cut the 1/2 drive screws, but will that hurt it for making taps? I don't know much about tempering metal(sp). Maybe I'm over thinking stuff.

But wow I like the idea of some 1/2-8 2 start taps. I can send what'ever thread I have left and I hope their will be enough for you to make a tap for yourself too.

aren't the dumpesterCNC nuts alreaded threaded for your rod? Why would you need to thread anything with those AB nuts? I think joe is talking about taping the HDP so that you can screw the Dumpster AB nut to the HDPE.

Nick,

I could be wrong but I thought he was talking about threading the HDPE the same as the dumpsterCNC nuts. He may have been talking about the four holes for the fasteners. Hopefully, I can figure it out when the parts arrive from Flyon.

If the hole in the HDPE is small enough to thread for the 1/2x8 two start and you tapped it after pressing the dumpsterCNC nut into the pocket in the HDPE, I don't think you would need any other fastener to hold them together. Once you fed the screw into the HDPE and dumpsterCNC nut the nut couldn't shift, at least not when it was new. But drilling the four holes and fastening them together is probably good insurance against backlash developing after the nuts wear. It would be real frustrating to have anti-backlash nuts that didn't really do any thing because the whole nut was shifting position.

Alan

[joecnc2006]

Yes i was talking about the 4 flange bolt holes on the Dumpster nut, this must be attached to the block and bolted to the machine otherwise you will have some play just having the anti-backlash held into place with the threaded rod.

Alan,

I'm pretty sure Joe was talking about tapping the four holes that attach the ab nut to the hdpe. I think I saw that someone tapped their hdpe directly for the 1/2-8 2start, but something else. The hole in the hdpe that I sent you is too big to tap, otherwise that might of been an option. As for the tap, I probably won't need it till I try building something else. Or better yet, if you do build it, I'll hold on to it, then if anybody here needs it, they're welcome to borrow it. I kind of feel like I should give back to the 'Joes Model 2006' community some how.

Flyon,

The parts arrived about 3:30 this afternoon. I have got the pockets machined and the nuts pressed in. I still have to drill and tap the 12 holes. With a little luck I will get them back in the mail tomorrow.
