The overall height of the battery is about 7-3/8 inches.
The clearance height of the storage space under the seat and under the bed of the trailer box is a little over 6 inches.
The underside of the trailer box has two ribs welded to it and with these ribs resting on the top of the frame, it will give me an added 1 inch of clearance.
That is a total of only about 7 inches clearance so I need to lower the bottom of the storage area to gain another inch of clearance.
I'm going to show you a step by step process of forming this panel for the floor of the storage space under the seat and under the bed of the trailer box.
I figure out how wide and long the panel needs to be and cut that out.
Then I mark where I need to make the bends in it and cut 1 inch long slits in one end of it at those bend marks ( this doesn't really show up very well )
I bend up 1 inch of the end of the panel where the slits are.
And I bend two tabs back down flat.
My home made sheet metal brake that I have will let me make a bend with an end tab pointing up but I can't make a bed with the end tab pointing down.
Also, I want to make two bends that will be 1 inch apart where the flat tabs are and they need to bend in opposite directions to form a " Z ".
The closest that I can make two opposite bends on my brake is 3 inches. Luckily, my son has the equipment to do these kind of bends.
First I set the panel up in his big brake with the end tab pointing down.
And I bend the panel up at 90 degrees.
I do this to the other side of the panel so both sides are bent up and the end tabs are bent out.
The panel is set up in another brake that will make close bends at opposite directions.
And I make that opposite bend in it.
Then I turn the panel around to make the bend on the other side.
The panel now has the center area stepped down 1 inch.
The two tabs that were flattened out earlier are now bent back over the end.
I'm done with what I have to do with the panel here.
The panel is set into the frame.
I make up a pattern for the end panel out of cardboard.
Then I cut this panel out of sheet metal and set it in place.
As you can see, the battery slides back under the bed and has about 3/4 inch clearance between it and the underside of the bed.
All that is left is to weld this in place.
I'll make up a piece of wood that fits onto the top of the battery that will keep it from bouncing up and touching the underside of the bed.
There will be another end panel that can be screwed in place in front of the battery to separate it from the storage area.
