Hello all, I have just subscribed to the site. So far from what I have
seen, this is the place I have been searching for sometime now. As I
mentioned I am new to some areas of my new project, which I will
describe later on to you, but first let me give you some background.

I was a toolmaker/journeyman machinist on conventional Ex-Cello vertical
mills. CNC was just making it's debut when I left the trade to take up
commercial aviation. Now, my project I want to do I to assemble a laser
cutter of approx. 40-50 watts, CO2 powered laser. I am doing this from
scratch and as most people in this forum have portrayed, expense is a
big issue here, so I will be attempting to do this as inexpensively as
possible.

I will be utilizing the CNC for the cutting operations, so I will need
to rely on many of you here to guide me along if it will not be a
problem to any of you. From what to use as my PC interface to what will
control the laser and axis of the machine, I will need to refresh myself
on, and this is where I will need your assistance.

I am also interested in a homebrew milling machine to do some machining
of molds for fiberglass lay-ups. All of this equipment will be to cut
model aircraft kits and parts for myself and my friends.

Thanks to all in advance, and look forward to a long life here in this
forum talking with most all of you.

Regards,
Don Hughes

Hello folks. Peter Tsukamoto here. I have just joined and am most impressed
with the potential of this group. I look forward to reading the posts
everyday.

In regards to the laser project Don is attempting, my only input would be to
use extreme caution around a laser processing machine. If any of the laser
energy inadvertently got directed into a persons eyes, that would be the end
of that persons vision. I doubt the laser goggles sold by the laser makers
would be enough to prevent damage. At the very least, a visit to a metal shop
that has a metal cutting laser and observing the shielding techniques would
be warranted. Peter

Peter:

Very good point you raise here. I am very aware of the reflected beam
that can arise with lasers and will do my best to encase the table while
the laser is on and/or working. Anyone who comes near the machine while
the laser is on will be required to wear special glasses as well. Also
the machine will have it's own room for working that has only one window
and a lockable door.

Thanks very much for mentioning it to me.

Don Hughes
