Chucky, I did an internet search a while back when I came across another catapault (couldn't spell trebuchet... still cant...),

and came up with a design I thought I could laser cut and laminated out of 6mm MDF,

but never got to execute due to size vs my laser capacity.
Just thought designing from plans that work could be an interesting project....

And now a POM tosses in another word I have to learn to spell... M_UK, was that name invented in the tropics for home delivery of mangos? 

If your first cut is too short... Take the second cut from the longer end... LBD
