You still in Frederick or Tn? There's a good welding shop on 355, but it's cost ya!
ovrszd might be able to provide some tips, he made one for his M9540. I paid him to build one for mine, but I am sure the dimensions are different.

Yup..that's what I'm looking for....definitely could do a cardboard pattern. That is one sweet looking piece of work. Don't know many folks down this way yet...outside of Knoxville....but will look up the boys on 355 when I'm back in Fredneck and see what they would need to do the job.
