I am getting ready to make the motor mount for my
KIS TR-4. I need a jig I can throw in the back of
the van and take it and all the parts to the welder.
I have not welded for 30 years so I do not want
to make a mess of it myself. Beside 4130 tubing is
expensives these days and I no longer own a heliarc.

Any suggestions?

Paul,
I am not sure there is a specific method that works best
for one-time use. I have had them come into my shop bolted
and wired to 2x4's as well as being tack welded, and even
clamped to angle iron and electrical tubing.

I do require rigidity, and prefer the firewall ends to be bolted
to a substantial firewall facsimile, or plate.
In lieu of this, or in addition to,
exact print dimensions.(customer responsibility).
I even had one come in all foamed together to the point
that there was no access to the weldment areas.

How about 3/4 plywood Archie. Do you think that would
be stable enough?
