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.
Here's a couple photos of what I did when building my engine mount. The
framework which emulated the firewall was fabricated from 2x2x.187 angle.
Photo Marv3-mm shows what the trusswork looked like before I took it to the
welding shop to be heli-arced, the other one Marvs-mm2 shows pretty much
how I went about clamping the angle together using the Lancair-supplied
engine mount to locate all the firewall side mounting holes. I stick
welded the angle iron fixture and gas tack welded all the tubes before
taking the whole thing to the welder. I built another solid fixture for
the engine side out of flat plate that replaced the engine when the unit
was taken in for final welding.
