Secjay's supercheap-skate pump project
Hey fellers;
I decided to try to build a somewhat ‘proper’ pump device thingy, instead of just using a jar and sucking the air out with a tube.
Steps Included:
1) I went and bought a metre of PVC piping, 50mm inner diameter. cost me about 5 bucks.
2) I cut off about 13” for the ‘tube.
3) I cut off a smaller tube, about 8cm across, and cut down one side of the tube.
4) I boiled some water in a saucepan and stuck that smaller, cross-cut tubing in, it melted, I rolled it out flat so it was just like a sheet. I then drew out a circle from the tube circumference on the flat sheet, cut it out, and remelted/flattened it out again.
5) Then I did some sanding.
This stuff is surprisingly easy to sand. took me about 10 minutes to get everything nice and smooth.
6) I drilled a hole in the flat circle ‘end cap’ in it’s center - that is for the clear plastic tubing stuff I have. it’s about 6mm across. The tube fits through nice and tight.
All thats left to do now is epoxy it all together with some “araldite” and I’m away…
I have a whole bunch of tubing left that I can use for other stuff in future projects (PE or non PE related)
I dont think I’ll attach a hand pump, not only can I not afford one, but I think I prefer the precision and control of oral suction ;)
(Doesnt that sound nice and appealing??)
My girth is about 5.7”, but the inner circ is about 6.2”. At least thats a good 1/2 inch I can expand. I’ll just have to try for minimal fluid build up.
I was planning to add in 5 minuite pump ups between my usual squeeze-type activities…
Any help?
