Hi Marni

I had a similar lapse of judgement this past winter and agreed to 
painting on a buck saw.   I  did  document the process somewhat in 
Facebook Photo Albums.

the pix are open to the public, but I think you would need to be a 
facebook user to access them.  the links are below

My project was much smaller , and in the end, I think I did some 
enlarging , print out and cutting to trace the outlines, and 
sketching in details with sharpie.

I am assuming  you will paint with acrylics....      I  did some home 
work as to how to approach painting on metal, and a good deal of 
effort is put into preparing the surface.

If you don't need to remove rust like I did, so much the 
better.    You will want to use a water based  acrylic primer for 
metal , from a hardware store  to underpaint your work.

I you used OIL based acrylic primer for metal, you will not be able 
to use water based acrylics over it...    or so my research told me.

In  my piece, I wanted the patina of the saw to show through as a 
background, so the priming was done "to shape"

If your entire piece will be painted, so much the better , you can 
paint a big primer square.

trace your work on the primer after two coats have dried well.

for the transfer without projection  I am thinking back to Amy 
Bartlett Wright's mural class using a sketch that is grided 
off,  then creating a grid on the enlarged piece with strings, and 
sketch in the contents of each square from the smaller piece,

square by square to keep the image proportional and fairly undistorted.

So, just some thoughts...  I hope you can access these FB photos...

Good Luck !

I learned a lot...   Like the next one will need to 4X the price  ha ha.
