4R8's table build

[4R8]

Now alot of what I'm doing is "over cooked", mainly to test what I can currently achieve with the tools I have. A rotary table would be nice and would let me do a few things easier and have a better looking final result but I don't yet have one in my possession. One day, one day.

Here's a couple of shots of the belt reduction housings. They use a 15mm wide belt with a 20 & 60 tooth pulley to give a 3:1 reduction.
They use a 12mm hardened shaft through the 60 tooth pulley to the 30 tooth pinion gear.
The side plates are 10mm Al which as usual, is covered in tape to sketch the designs on and save on too many scratches while being thrown around the shop.





this one is designed for the X axis. The Y (currently under construction) is similar in design with a few slight changes to suit their particular location.

Here's where the X unit will sit.



I still need to mill out a pocket in the carriage to allow the unit to go into it's proper location, with the pinion closer to the gantry tube.

Th Y axis, will require one for each side and will be mounted in the following location. Once built, the gantry side plates will need trimming and a pivot point added. The final location will be directly below the gantry





The two plates will be separated with some Al round bar which will be bored and threaded.
Once they're complete, I'll look at adjusting the profile of the pieces to make them a bit easier on the eye. I'm not a fan of the boring, square shape. They just don't look finished.
