Corvair Engine Mount

9.0

DETAIL:

I ordered the rest of my steel tubing for the mount from www.shapirosupply.com.  The tubing came in a few days ago and today I decided to go for it.

Using a 1/2" thick steel plate as a jig/table I drilled holes in it at the proper locations where the spools will meet the firewall.  I then ran 3/8" threaded bolts through those holes and into the spools and then put some nuts on them to keep them in place.

The next job was to weld up some jig pieces to the table.  I used some old 2" angle iron.  Basically I welded a 26" piece of 2" angle iron right to the steel table in the proper location and then tack welded my tray to that.  This suspended the tray at the proper height above the steel table and from there all I had to do was connect the tubes from the spools to the tray.

Notching the ends of the tubes is not difficult just time consuming.  You have to go a little at a time so that you do not remove too much material and create a gap that is too large to be filled when welding.  It took me about 15 minutes per tube.

I tack welded each tube in place making sure not to spend too much time on one joint.  I moved around until I had all the joints welded.  Once it all cooled off I removed the mount from the jig.

I still need to put the diagonal tube and gussets on but for the most part the mount is complete!

Weight is 5lb. as of now and will probably be closer to 6 when it is done.  It fits onto the firewall perfectly.
 

 
Here's the 1/2" thick steel table.

Below you can see the tray tacked to a steel angle iron jig piece
which is holding it above the steel table at the proper height.
