Project Ramp

[Mickly]

So using CAD (Cider Aided Design), I have made a 1/4 scale model of a bike lift / ramp ( not for a 1/4 scale bike you muppets ) to see if it might be feasible to build one out of wood. Now I need to decide how much it might cost v a second hand one plus how much effort to build it … also how prepared am I to just laugh when it collapses on top of me ?

It will depend on what wood you will be using and the weight of the bike.

I would be careful even if you use oak or any other hardwood that isn't strong enough for the stress.

If it's, an 125 then you will be fine with oak.

The structure doesn't really looks like 1:4 ratio or you will be using very thick beams.

Remember to allow for aluminium plate on the platform for better distribution of the load.

Thinking of using 100 X 60 CLS

the bits for the model are 25 X 15 (ish) old bits of MDF I had lying around.

Also thinking of using OSB on the platform with some more supporting beams if needed

I saw something similar where they'd cut and extended a hydraulic bike lift.

Just something to consider is that the inevitable spillages of fluids on to osb would worry the bugger out of me ! Osb is not the most resistant of materials.

I know it`s dearer but Ply or overlay with checkerplate before anything disappears through it lol.

For the top platform I would say resin layered 19 or  22mm plywood 

Usually known as phenolic resin plywood

So, we're all concerned about the platform, I would use OSB, with a 12mm rubber mat (the kind for horse stables) screwed on top. Easy to wipe, and will give good grip for the side/centre stands.

How about..

Phenolic resin plywood then Durbar plate and on top the rubber Matt?

I made a 7ft ramp out of 18mm ply with 2 2x4 on the back, it takes the weight of my Fazer no problem.
