Homebrew PCBs

Hi guys,

 

Since we're talking about cutting FR4, I thought I would share my creation
with you.  I made a small "PCB table saw."

It's essentially a Dremel flex shaft attachment affixed to a plate of
aluminum.  I originally wanted to use standard cut-off wheels because of
their availability, but the flex shaft handle was too large, or the diameter
of the wheel was too small. depending on how you look at it.  I removed half
of the handle and created a bearing block to hold the axis of rotation as
close to the table as possible.

 

It works fairly well and the adjustable gate allows you to make rather
straight cuts.  The cutoff wheels, while cheap, are fairly thick and
non-planar, though.  I'm looking into using much thinner steel saw blades in
the future.

 

I have DWG/DXF files of most all of the parts and I wouldn't be averse to
sharing them.

 

Best regards,

 

 

 

 

Paul
