Seat adjustment

Ok lets cut the single heavy frame.

Tack on some support plates. and 5 x 30x30 box legs 3 in the front 2 in tut back.

After the first test fit this leg had to be moved 60mm to the right to land in the dip like all the other 4.

Close but dim cigar. nearly had a hole in the right place but accident. 

Back OS leg needed to spin 90 degrees clockwise as the hole would be in the cill and no way of getting a nut on it.

drill pilot holes at each leg after making sure the seat is square to the side of the van.

Now fully weld, paint 

I want the ability to remove the seat to service the boiler (Truma 4E) so I have made plates that bolt to the floor and have countersunk bolts to fasten the seat from the top.
