I thought I'd write up a post about the seats which Im currently installing into my atom 3
I've always hated the bench seat but never really wanted to go as far as shelling out for the expensive tillet option. After seeing many posts on the subject over the years i thought I'd give it a go at making my own seat bases and fitting some lightweight fibreglass seats. I went for some generic gloss black caterham style seats, as these and the runners were easy to get hold of and didn't cost an arm and a leg.
Now I had the seats chosen, I got to work on the seat base, which seems to be the biggest hinderence to fitting individual seats in the earlier atoms according to all the posts I've read.
Step 1:
I started with a cardboard template, making sure the bolt holes were in the right places, and setting the height from the tub. I used modeling cardboard to create this with. A bit of trial and error to start with but turned out ok. You can see the template in the first photos.
Step 2:
After I had made the template, next step was to Measure it and put into a basic cad drawing with dimensions added, I sent this to my local fabricators who were able to make a prototype for me out of 4mm thick Aluminium.
Step 3:
Once I had the prototype, I then went about seeing how it fitted, a few adjustments needed for the location of the front bolt holes in the side mounts. And some reinforcements needed. Once the changes were added back into the cad drawing, I sent the prototype back to the fabricators for the changes to be made
Step 4:
The additions were made to the final seat bases, they were then powder coated in Matt black and collected today. I've fitted the drivers seat and it's a perfect fitment.
I have some high tensile M10x25MM bolts on order for the base arriving tomorrow. Once these arrive and I've managed to fit the passenger seat I'll post some photos of the completed set up!
