so in my engineering design class we have to build a project. some kids are (going) making a trebuchet, some are(planning to) making a hover craft. I figured why not make a surfboard. My teacher is really pushing us to do some engineering and though i am stripping my first board(clark foam) i made to make a fish, I really want to do something a little more technical. I want to make a compsand. here are my planned supplies.
Ken at Segway is a great resource, has a superior product and unbelievable customer support. He will probably throw in the high density foam to use around the FCS plugs (use gorilla glue to put in these inserts).
With 1 lb foam (and no stringer) you will probably need a “rocker table” of some sort or the blank might flatten out under vac. Ask Ken
Check ebay for vacuum pumps. I found the fiberglasssupply ones pricey and maybe not necessary unless you plan to go into full time production. Look for a pump rated 24/7 continuous duty, with vacuum gauges and bleeder valves so you can forgo all the vacuum reservoir, vac switch and check valves, which to me seem very expensive and complicated.
The top of a glue bottle works great as a vac hose attachment- fits the shop vac for initial pull and the 1/4" hose for final pull (search my “EPS plywood fun gun” thread for photos).
Don’t forget bubble wrap to use for a bleeder. Additionally I used some heavy sponge right under the hose attachment so the hose doesn’t just suck down at the attachment point.
ok. I like the idea on the fridge compressor. How do you make that? I am getting rid of fridge(still runs fine just old and smells bad). And i have al;ready worked with Ken on one project and he has great customer serivce and I wam going back to him for all my EPS needs
