Homemades - average-sized HAMP

I recently built a HAMP with a leftover pvc.

It took me a lot of work to built this and its not as good as i expeted,but i'm happy with it :)

it is portable too :p

the pump draw is of this length shown in the pic,almost perfect seal :)

here is it fully dismantled.

plunger head ruined upon friction. lol :)
