Hi,

Your carriage is very similar to the design that I am working on. What
size of wheels did you use and what load rating do they have?

One option that I am planning on adding to the carriage is a drip plan
for the Bridgeport to sit in so oil and coolant are caught before they
reach the floor. I like the idea you have for filling the space
between the frame and the mill so chips do not collect there.

The angle iron that you used in your frame...is the angle flat on the
floor or is the angle edge sitting on the floor?

The clevis attachment point is something I am also adding. I am
planning on having an attachment point on both the front and the back
of the carriage so one can pull the frame into a trailer if the mill
is moved to another location.

I built a permanently attached mill carraige very similar to the one
you are contemplating. The carraige is used to move and level my
Bridgeport-type milling maching. The frame is made from 1/4" angle
iron and plate. The front casters swivel and the rear are fixed to
make it easier to steer. The jacks are fabricated from 1" threaded
rod and are threaded into coupling nuts welded to the frame. The
jacks have swivel pads on the bottom and a hex head on the top. The
front of the frame has a clevis connection to attach an approximately
4' T handle that I use to pull the carraige. This is much easier than
pulling on the machine itself. I used bondo between the frame and the
mill to prevent metal chips from collecting in the crack.

The carraige moves easily and the jacks level the mill with very
little effort. The carraige is very stable both on the casters and on
the jacks.

I have posted the following pictures of the carraige in the
metalworking.com dropbox:

This is the first time I have posted any pictures in the dropbox so
please ignore the other mill carraige files. They are just larger
versions of the same photographs. The following are the links to the
dropbox photographs:

Again this is the first time I have tried to insert a link so if it
doesn't work you can just paste the address into your browser.

I hope my experienc provides some ideas for your carraige.
