Spring Plungers?

[mimosatexas]

I don't care about the drama the star of this video seems to conjure up, but does anyone know where to source the spring plungers he is using in his unit, or something similar?

I have been using ball catches from lowes (like these: http://donnahuebsch.files.wordpress.com/2012/07/adjustable-ball-catch-1.jpg) but I'm finding I want a little more movement to make loading the screens easier.  These just dont have enough distance in the spring.

Any ideas?

edit: the two closest searches I've found are https://www.google.com/search?q=SPRING+STOP+BUTTONS&client=firefox-a&hs=SLO&rls=org.mozilla:en-US:official&channel=rcs&source=lnms&tbm=isch&sa=X&ei=E-IkVJfVE8WsyATvnYLYBg&ved=0CAgQ_AUoAQ&biw=1920&bih=955 and https://www.google.com/search?q=spring+loaded+delrin+cap&client=firefox-a&hs=mzi&rls=org.mozilla:en-US:official&channel=sb&biw=1920&bih=955&source=lnms&tbm=isch&sa=X&ei=1uEkVJS0CZSfyATA5oKoCg&ved=0CAcQ_AUoAg but i still havent come across anything exactly like what is in this video or what is used on the tri-loc

Everything he uses can get gotten from Grainger I believe.

Extruded aluminum and such for sure.

www.jwwinco.com probably has them or something similar.

Mcmaster-Carr if you haven't checked them yet.

Sometimes the hardest part about finding an item is finding the correct name for it.
Or at least what everyone else calls it anyways.

the frame and stops etc are not an issue, but those stupid spring plungers are a pin in the ass to source...

I have done every keyword search I can think of on sites like grainger without luck.

[mimosatexas]

Yea the correct name seems to be the biggest hurdle.  I have looked at all of these sites without luck.  Stuff is close but either they are really small, have the wrong housing, or are super expensive.  Normally I am pretty good about sourcing stuff like this for my DIY bullshit...

For example, nothing here fits the bill, though about a dozen are close in one way or another: http://www.jwwinco.com/products/section10/

He's using this guy with a different plunger.

Any idea where he is sourcing the plunger?  I found that exact model a few places...

MSC industrial has a lot of jig fixture parts or any supply house that sells machine tools such as lathes and milling machines.

Use their stuff and modify it or make what you need. Some of the best deals on the t slot and fittings can be found on Amazon.

is 1/4" of movement enough?  I feel like the stops in both the video and on the tri-loc have more....

Ours only has 1/4" of travel ability because the screw on the back is 1/4" away from the frame.  We have no problem inserting any of our screens.  I would go with a circle bump though becuase we are always having to twist ours so that we can snap the frames in.  Hasn't aggravated me enough to change out the spring stops yet but would be better to have ones that would not require twisting.  Not sure if a 1/4" of travel on our style is equal to a 1/4" of travel on the circle bumps though.

Great info.  Thanks!  I went ahead and bought 3 of the circle head ones.  I'll post picks when I've updated my unit.

Bit later but if you want a longer stroke you could buy spring return air cylinders and not hook air up to them

That's probably where I'm going since I have (relatively) drastically different frame sizes and don't want to be adjusting the FPU constantly.

hmm that has me thinking...
