First Bridge

So a start is made on my very first attempt to make an aluminium flat bed bridge.
 I started by cutting and clamping all the base bit together and making sure all was square and measured correctly a start was made at drilling and riveting the pieces together.

Now after finding the right size rivets and drill size i.e. 3mm rivets/ 3.5mm drills assembly started.

When the final rivet was in place it was time to start and work out the correct placement of the longitudinal track support bars and making sure the clearances are adequate as the bridge is approached by a curve and so overhang had to be taken in to account.
