I needed to make the mounting location bigger to accept two batteries so I grabbed up some angle and made a tray. I decided that the material I used weighed to much so I put the angle on the lathe and lightened it up a bit. Trimmed the sidewalls down and put a slot in the lower tray angles. I then created a battery solenoid mount to hold 3 to 4 solenoids Countersunk the rivet 426-4 holes for mounting the battery box together and solenoid mount.
