Quite an Unusual one

Nice work Boyan, figured you must have epoxied both axis. Time consuming buisness but must be satisfying to get it that precise!

At the end i managed to move further the build. Thanks to my new friend and fellow forum member Jeff Potter who helped me a lot with machining all aluminum pieces for me.

Now what happened:

-i bought some sound insulating stuff so i can make the garage quiet, so nobody bothers me in the future when i am working. I mean the tourists that come now in the summer and rent the houses around me

-tested this and that and at the end finished the prototype of the fog-less mister and tested it while milling the aluminum pieces for the Z

-tapped and started putting the Z box together , 5mm tap stem fits perfectly in the 6mm drill guide

-The rails were meant not to obstruct the back plate. the idea was to use the back plate as a guide to mount them perfectly flat and square

-mistake in the design. How the hell i was going to screw the ball screw nut supports. So i decided to cut a slot and at the end they will be screwed with 3 screws only.

-as everything was machined very precisely and as i helped Jeff make his machine work in 3D mode, all fit perfectly together

-the idea of the shortest front plate is if i lift and hide the spindle to its highest possible position inside the box, so i could reach and change tools without problems

-the Z looks like a bad ass missile warhead

Some more. I hope you like detailed photos of builds. /there is 10 image limit and i like taking photos :-)/

-The rotating ball nuts were press fitted and all worked fine. Though i have to change small things in the design, things that made me think a lot how to mount all of it together. And how it will be dismounted in near future if i decide to repair the belt...

By the way i decided to start making together with Jeff and selling the assembly in the near future, for forum members and other. Redesign it a bit for any specific case and machine it properly. It is a result of the fact that i spend too much time fiddling with that assembly and investigating. And trying to find who will do it for me, and worrying if they did it properly and repairing their mistakes...
So i would announce it at its proper place in the forum, hence will stop to brag here.

-tadaaaa, second mistake. The 30t pulley is too much in front so hits the Z back plate

-mistake repaired easily, thanks god

- dry test looking for mistakes

-ready to "surface" straight the side plates

-i knew the sound proofing of the garage will pay off. why this always happens at lunch time when all normal people rest. had to take the bigger "surface" hammer and "surface" the plates for about half an hour

-that's better

-another dry test and squaring together

Wow, 3 posts, it seems i had a lot to show and say

-the Z again, 2 spot welds to hold the side plates in place

-thats why i did not bother before too much rectifying the back Z plate. No i pushed it flat to the whole straight assembly, so all fell in place. Then spot welded CAREFULLY

-I know Dean, OTT and too much but that cost me only 30euros more. I promise never to do that again.

-squaring the Z in both directions against the straight edge that lies flat on long rails. this took a couple of hours to do it properly until satisfied

-another consequence of the mistake i made here

- That must be the most bad ass DIY Z axis i have seen on single gantry machine

, OTT but make me proud and smiling when i look at it, so i assume it was worth it

, did i say it looks like a missile ready to launch ?

See that big, no - huge mill vice? Thats a gift from Jeff for the build. have to rethink this and that for the bed. I never imagined i will have some day such a beauty. On other hand its not fair some people to have 3 of them
