i was wanting to make a small gun that has a bike pump on board for shooten marbles has any1 else on here made something like that that i could get some ideas from? had a bit of a look around but didnt find much
Well theres this or theres the LOKI with on board compressor .The thing about on board pumps is that they are often too cumbersome to use effectively. I would advise against it.

was kinda more interested in somethen not terribly powerful (not having to pump it too much) maybe even just enough to put a hole in cardboard from a distance more for target practice without having to have a compressor or separate pump

try something with a small chamber, like 5 inches of 1.5 inch pipe.
i know with 6 inches of 2 inch pipe i get up to 120 PSI in 12 pumps from my bike pump. literally takes 15 seconds to fill.
if you really wanna go overboard, get a CO2 setup, a slide valve, a QEV, and make some sort of bolt-action reolading system and make the air-flow semi-auto and just load a new marble in for each shot.........
hell, it takes 20 PSI to get a marble through cardboard....... lol.

if you want something accurate with not too much power i would go for an airsoft bb shooting gun which you should get good range and accuracy with.
i have thought about doing this but the main problem was th pressure i would get from it. i have used a hand held pump to pump up a 3'' by 9'''camber and took forever and got to roughly 40psi. but using a smaller chamber would help.
firstly you could use a basic rifle design. mount the pump under the barrel and fit the chamber in the stock. or using a under over design have the pump mounted next to the chamber. its up to you.
