This document details the parts that need to be

machined.

Most of the parts are now available already

machined. Each part is listed with the material

needed to make the part and the cost of the

machined part.

Motor Mount & End Bearing Mount

The motor mounts and end bearing mounts are made from a 4”

square aluminum extrusion cut to a 4” length with a wall thickness

of 1/4”.

The drawing on the right shows how three sides of the motor

mount would look if it they were unfolded. The fourth side is blank.

The End Bearing Mount is the same as the motor mount without the

hole for the motor mount.

The next three pages describe the details for machining the motor

mounts and end bearing mounts.

Mark one of the open ends as the top and do all your measuring

from that end.

Using your templates is a good way of keeping all the holes

properly centered.

Care must be taken to make sure that bearing block holes on each

pair align up properly. The pre machined parts are sold as pairs.

Motor Mount Motor Side

Machining of the center hole is best done on a drill press or a

machining center. There are various types of fly cutters and

hole cutters available to cut the hole.

Some extrusions will not be exactly 4”. mark a vertical line

between the open ends that is exactly in the center..

Attach your template making sure that one side is flush with

the open end that you have marked as the top side. Now

make sure that you can see the vertical center line through

the center hole in the template. Tape the template to the

extrusion.

At this point, I use a 1/8” drill bit and drill a starter hole

through the templates.

Once you have the centers marked, you can use a fly cutter

on a drill press or a hole saw on a drill press to cut out the

center hole for the stepper motor.

The mounting holes for the stepper motors are drilled and

tapped for 10-32 socket head screws.

Price per pair $60.00.

Quantity needed: 2 (X and Y axis.)

Motor Mount Mounting Hole Side

Some extrusions will not be exactly 4”. mark a

vertical line between the open ends that is exactly

in the center..

Attach your template making sure that one side is

flush with the open end that you have marked as

the top side. Now make sure that you can see the

vertical center line through the center hole in the

template. Tape the template to the extrusion.

At this point, I use a 1/8” drill bit and drill a starter

hole through the templates.

The four mounting holes are drilled for 5/16” The

holes are centered on 1.5” spacings.

Motor Mount Bearing Side

Some extrusions will not be exactly 4”. mark a vertical line

between the open ends that is exactly in the center..

Attach your template making sure that one side is flush

with the open end that you have marked as the top side.

Now make sure that you can see the vertical center line

through the center hole in the template. Tape the template

to the extrusion.

At this point, I use a 1/8” drill bit and drill a starter hole

through the templates.

Once you have the centers marked, you can use a fly

cutter on a drill press or a hole saw on a drill press to cut

out the center hole for the bearing block.

The mounting holes are drilled and tapped for 10-32 socket

head screws.
