but you say u want a flipper- actuators are slow so you'll end up with a lifter
the one im using is a fast one(2inches per sec) but can only lift 35 pounds worth of weight
That's not a flipper - still a lifter.Quote:

the thing is pneumatics cost alot of money and i dont have much money.So linear actuators are the best for me. The ones on ebay arent that good so firgelli actuators are probaly the best for me. With my birhtday in November i'll see how much i'll get from that and see if i could upgrade to pneumatics.
honestly i've gotten some rate bargins off ebay
if you buy one of that website you'll probabily find it will be really expensive,
i've got the majority of mine for about £25 ish each thats pretty cheap, if theres not any on at the minute there will be soon just keep checking back
Thanks cal. I'm after a 2-3 actuar length. The ones on Ebay at the moment are for T.V's.So I'll wathc hout for bargins
Sorry got it wrong it's ActuatorQuote:

Make your own using a threaded rod and nut. Jamie is the best one to speak to about the mechanism. I'm sure he has some pics of kaizers lifter kicking around
My ears are burning :proud:
Kaizer's lifter uses parts from a scissor jack. You can pick one up from a breaker's yard for £5. As an example:

I used the threaded rod that runs through the middle and one of the nut pieces that holds the top and bottom halves of the frame together.
I attached the threaded rod to a butchered output shaft of a drill motor and when it spins and I hold the nut still, the nut will move along the threaded rod. If you attach a linkage (just a couple of strips of material) between the nut and the pivot point on your lifting blade, that linear movement of the nut along the threaded rod will be transformed into an up and down movement of your lifting blade.
I don't actually have any decent pictures of the lifting mechanism in Kaizer as it tends to be hidden in most shots by stuff over the top of it, but here is a crude diagram that covers the basic principles:

The mechanism also moves much faster than any linear actuator I've ever used but still has enough strength to lift another featherweight (more so now as I've recently braced a couple of weak points). This video gives an idea of its performance:

Actually, here are a couple of pics. Not the best shots but hopefully will give an idea as to the setup:
