I have a bit of a hard-on for getting the risers done now. I have had them for quite some time and was led to believe that I would be getting assistance to fit them, but it now transpires that is never going to happen. This mammoth task falls back solely on myself to do, which has been a scary thought given my lack of experience with such things. Most people start with something small and easy to do like a car restoration and maybe never progress much beyond some simple car bodywork. I've opted to jump in at the deep end and replace major load bearing parts that sit beneath 5 tons of double decker bus bodywork. Furthermore, there are no instructions or You Tube videos on how to do it. I know what I am trying to achieve but it is far from an easy task. The rear of the body needs to be lifted off the risers so that they can be removed and the new ones fitted between it and the chassis. I need to achieve this without distorting or (worse still) dropping the body. If the latter happens, it's probably game over and I suspect it will be a case of scrapping the bus, having it towed away unceremoniously. I can see why nobody wants to help. But I jumped in with both feet to this restoration so will give it my best shot.
When risers were replaced by London Transport, they lifted the body off the chassis to do so. They had cranes and they had jigs that cradled the body and could tilt or turn it so that it could be worked on. They also didn't have 50 years worth of corrosion to deal with. I don't have those luxuries or benefits, so the plan I have devised is as follows:
- remove the platform (not that difficult, it was so badly rotted and was not an original one)
- remove all the connected items on or around the risers
- remove as much weight as possible
- brace the inside of the bus body to prevent the sides from caving in
- lift the bus a few inches using a 10 ton jack (it's an investment required if you own a bus)
- support parts of the body accordingly
- lower the body onto the supports, thus allowing the remaining weight of the body to be transferred from the risers to the supports
- remove the old risers and fit the new ones
- lift the bus again to remove the temporary supports
- lower the bus onto the new risers
And a bit more (bus lifted to start riser work)...
