Model-Building Workshop - A2Z CNC Extended Table for Sherline Mill
If you find the information on this page useful or interesting, please take a

Thanks!
Overview
 A2Z CNC Table Pete Brown, May 23, 2005In May 2005 I ordered an extended travel Sherline milling table from Tim
Goldstein at A2Z CNC. The
product was brand new at the time, and I managed to get in both the first order
for this product, and at the same time, the first order placed through his web
site. Read on below and you'll see why I was itching to get this product in and
installed.
This page is currently a work in progress.
Dimensions
The A2Z CNC replacement table is wider, thicker and longer than the stock
Sherline table. Here are some of the key dimensions:
| Dimension |
Stock Sherline |
A2Z CNC Table |
| Length (X) |
13" |
19" |
| Depth (Y) |
2.75" |
3" |
| Thickness (Z) |
0.9" |
1.0" |
| T Slot Flange Thickness |
0.10" |
0.125" |
| T Slot depth at Center of Slot |
0.20" |
0.233" |
| Total X Travel |
9.0" * |
14.25" |
* from Sherline literature.
The dimensions above were all valid at the time I wrote this page. It's
possible (if you are reading this several months or years from the time I wrote
it) that the dimensions have since changed. Note also that the dimensions are
based on a Sherline 5400 mill purchased in 2003 and the A2Z CNC extended table,
with tapped holes, purchased in May 2005.
Installation

Under construction
Remove existing motor mounts
Slide existing table off of saddle
Remove X axis lead screw
Clean and re-lube using super lube
Install new table (back out X axis lock)
Tighten gib. If fully tightened and there is still play, you'll need to install
a brass shim per Tim's instructions.
Mount motor mount coupler to new leadscrew (be sure to use loctite on the
nuts!)
Lube and install new X axis leadscrew
Mount motor mount to new table
Install stop screws or limit switches
Run through motions and check for play. Adjust gib and anti-backlash screws as
necessary
Re-measure your steps-per-inch and enter them into your CNC controller software
(the stock screw differed slightly from this replacement screw in my case)
Conclusion
 TS Engineering Modular Vise Pete Brown, May 23, 2005
If you have a Sherline mill (5400, 2000 etc.) and you want to have an
additional 5.25 inches of X axis travel or mounting space (think rotary
table with a 4 jaw chuck), then I highly recommend this upgrade. I have wrapped
up my stock Sherline table and permanently retired it into parts storage.
I have recently purchased limit switches, and hope to install them soon. Once I
get those installed and wired up, I'll be sure to provide the additional
information on a new page in this section.
