This is my first post but I have looked over a lot of the threads on this forum.
I have never used a cab machine before so all of what I have done is based on info from this site and the internet. This machine has yet to be turned on so it is all a theory for now as to if this thing is even going to work. I wanted to build an 8 Wheel machine but I only wanted to start with 6 wheels and see how it goes, that is the purpose of the flexibility of the base that holds the shaft, the pillar bearings can be moved to accept the additional 2 wheels. I experimented with several different hoods from bathroom wall sheeting (would not hold its shape), stainless steel 16ga ( I couldn't get it bent for a good price) and I finally ended up with acrylic that I bought from Lowes.
I actually did not have hardly any of the items needed to build a machine so I had to buy most everything. I bought most of the items either from eBay or amazon based on price and sometimes delivery. The items used are as follows
Added pillar block spacer to raise wheels
Used magnet (i happened to see laying in my shop) to attach to base unit and hinges for belt adjusting, theory is the motor weight will be enough for the belt
Hood splice is 2 pieces aluminum flat bar
Drilled hole in collar and put a screw in it to grab the wheels when they turn to keep from slipping. Wont work on Galaxy wheels (no holes)
You can also see the flat I machined down the shaft for set screws to hit
Items left yet to do
As I said this is my first shot at this so if you see anything that I should change/add/delete please let me know
I Thank you in advance

I actually did not have hardly any of the items needed to build a machine so I had to buy most everything. I bought most of the items either from eBay or amazon based on price and sometimes delivery. The items used are as follows
- 1" stainless Shaft 36" long, per-drilled with left hand threads on the left for 1/2-13, 1/4-20 on right, key-way was ordered with shaft, centered 8" long ordered from Ebay seller
- 3/4hp 1725 rpm motor, mounted on aluminum sheet I had, added hinges and harbor freight tool magnet to attach to the base, made for easy removal when stored, hinges allowed for belt adjustment for pulleys
- 2.38" single pulley 1" bore with key-way for shaft, 4 step 5/8 bore, 2, 3, 4, 5 inch pulley for motor
- 10 Stainless 1" shaft couplings
- Misc brass fittings, water jets, for the water system which will be fresh water only
- Friend of mine gave me the metal base which i cut to length
- Acrylic sheet for hood, I could only bend 24" so that is why it has a splice.
Original mock up, thought wheels too close to bottom
Need support for acrylic hood as I did not do a great job on bending, will add all thread and handles for attaching
Added pillar block spacer to raise wheels

Items left yet to do
- modify the shaft couplings to attach to wheels (drill and add screw to each) I have done a couple for testing
- add water system
- cutout for belt to motor, wiring
- All thread, and handles for supporting the hood
- add LED lighting under hood
- Hand support/cushion , adjustable face shield ?? I don't know if this is needed or not.
- Run-test (while whispering "please don't blow up"), rebuild, and adjust
As I said this is my first shot at this so if you see anything that I should change/add/delete please let me know
