HansG & QSPSB,
After reading your posts I went out to the shop & placed the castings on a surface plate.
All three are very flat & straight........Lucky I guess. I have 2 enco's & 1 Grizzly and they are
all very high quality product. Are yours from Taiwan?
Observe the photo's in my first post you can tell that the table top is nicely finish ground.
Step 2- X axis Modifications:
The two #24 Longtudinal Screw Brackets are bored to capture the 26mm O.D. Bearings.
This operation requires 4 # 6000 metric bearings. See enco Photo
Disclaimer: The enco bearings I bought are not NSK
2 Flange nuts 5/8-10 plastic # 91984 $19.25 (www.roton.com) 1 for ea. Axis
I add a support bracket to the flange nut which wiill be shown on my next post.
For the motor mount side: Nema 23 motor mount for Acme CNC Router $24.00

This completes the X axis modifications..The Y axis is a little more challenging!!
