Nice cnc work brader!

damaged my collet holder cover when Chisel told me to carve it, apparently it had a very shallow dome and thus I bore through. So since I had not much to do today I thought I'ld make another one, this time bore for a collet nut (I ordered an extra)...
made mostly of Oak and extended with rosewood.

Happy to see it lined up since I did not do it on purpose.

finished with a thick coat of wax to prevent moisture.

The creator of the Platform CNC recently announced an upgrade to the machine making use of linear rails. The upgrade is nice since there will only be additional parts to accept the existing parts...
So I set up the platform to cut aluminum...

and after several hours I have the side plates completed...

I'm so excited to finally use (Hiwin) linear rails...

Had a car battery problem which wasted most of my day but I was able to cut the linear mounts that I need for the upgrade...

Came out well and it made my day... what was left of it anyway.

The drop nuts arrived today..... woohoooo and they look pretty good too.

but pretty good looking is not as important as fitting right. So test I did.
Drops in well..........

I does lock in well too, that makes it alright... right?

well, yes and no. Yes it locks perfect and No bec it isn't 100% biting. So I tried to figure a way to get them to bite perfect all the time.

And what do you know they work great...

Wohooooooooooo... all I need now are the linear rails and an extra helping hand as this will be gruelling and probably take a day or two to complete. But I am excited and that is important too....

needed some brass plates for a speaker stands build and the cnc does not disappoint.

even had time to play around with foam...

[timber715]

All perts arrived and tested with the aluminum that I have cut...

Tomorrow I start the upgrade. Anyone in the area is welcome to join and help me with the heavy items. I definitely can use extra hands.

Started the cnc upgrade today. I was able to complete replacing the Y-axis from v-rollers to hiwin linear guideways.

If you use two bearing blocks per side, it would provide a stable and rigid axis... but if you use four!!!

Super solid!!! it isn't running yet but I can tell this would improve my machine by two levels.
I was also able to amost complete the X-axis until I ran out of M4x20mm bolts.... dangit!

Anyway, I went home with dirty fingernails and sweaty shirt but with a wide grin...
