no clue...... it may take 3 to even get the height... i'll play tomorrow once i take the head apart...
I was just thinking that valve springs only have like .5"-.75" or so travel. Figured you'll need like 3" total travel. Maybe you don't need that much 
Hard to guess without items in hand to measure/guess lol

well, that's 3" angle... the depth to center is 1.75"... so figure you'd need 2.5", minimum probably....
these look really good.. 6" long, 1" post would work great...

but i have to order $35.. so, 3 of them.. $47 total....
see if I can come up with a cheap/free alternative...

see if I can come up with a cheap/free alternative...
so here are 3 stack and tacked.. it's 6" high... it's ALOT of spring pressure....
i can run it down about 2" of comp in the press (love air!
) but I wasn't comfortable going anymore really without it caged with a post... I had a hunk O' steel as a shield, but I don't want a missile in the LAB™ at mach 2...
anyway.. I'll see where I head with that as I figure out the top... on that note......
* Ryoken musings....
one thing about the springs are, I'm not even certain I need them.... if I pin the upper to the ram somehow.. it should retract up with the ram I would think...
that said... I think I've decided to build 2 interchangeable tops here...... one, a lighter duty, much more complicated, finger break, with the press fingers made from 3/8"... than if I feel the need, a thicker solid upper, all welded together that I could fab up pretty quick.... just slide one off the posts and put the other in for HD stuff...
just not sure which to build first... basically all I have is 3/8"... LOTS of 3/8".... I don't mind lamming 2 together and doing a single 3/4" wide, 18" long one with the press edge being welded, and shaped.... but I definitely don't want to try and make individual fingers that way....
I figure anything I'm gonna use fingers for, will probably tend to be a bit lighter material, etc. bat tray, etc....
should have a good LAB™ day tomorrow...

Pull the inner springs out. I guess that would depend on how much the upper part ends up weighing.
yeah, i thought about that... and high spring pressure wouldn't necessarily be a bad thing, but it may be better in an encapsulated scenario, as opposed to interchangeable uppers... BUT, both of these uppers are looking to be pretty stoutly, soooooo.
the nice thing would be, I could just use the shafts from a couple 5/8" tire irons kicking around for posts if I want... grabbed one, loose fit, but I think that may be better than the closer tolerance, tube in tube method... tho iirc, a 3/4" post would fit REALLY nice inside these springs... I'll play with it tomorrow... tho I'd actually need to run down to the shop and pick up a full 305 head i have, as opposed to the 5 springs on this 4.3 to actually make that, I was short a spring today anyway.....
gotta start hacking up a bunch of 3/8 tomorrow.. think I'm gonna work on the more involved finger brake tomorrow mostly... think I have a good plan for that... maybe I'll run out to the other depot and see if they have a saw blade, nasty weather pending...... tho I can do a bunch of the flatbar cutting with the bandsaw...

alright.. here's the plan... gonna run the springs... i could always change them out for others later if too stiff.. i did pull the inners, didn't do a ton, but helps... just ordered 7/8" rod for posts, it'll be here tomorrow...
gonna run 4 fingers.. 2 6", and 2 3".... cutting all that now... gonna run 3/8-16 bolts on the "squish" plate....
gonna run 4 fingers.. 2 6", and 2 3".... cutting all that now... gonna run 3/8-16 bolts on the "squish" plate....
so here are the pieces and parts for the build basically... other than squish hardware...
obviously the posts will be cut down, etc.... not sure if i'll need 2 or 3 springs per side.. no big either way...
here you can see the washers that I'm gonna weld to the ends of the tubes to ride on the springs... i figure this will work good and allow for any misalignment.. i'll carbide out the washer to a nice loose fit....
also the notches i'm gonna run at the ends of the top plate to tie into the tubes...
which leads me to needing my belt sander running good for a bunch of upcoming work...
more LAB™ upgrades coming shortly...
my poor Grizzly belt sander.... best $50 i ever spent... it was basically new...
I've beat the snot out of this thing.... I don't even use the disc... at one point, the deck had fallen off the post and was laying on the motor and i didn't even realize it.... still runs great tho...
decided the other day to order a couple fresh belts as this one is pretty worn and I knew I had work coming up...... hopefully they'll be here in a day or 2....
so i started looking over it today and decided to build an actual proper shelf/table for it when it's in an upright position.... it also can act as a backstop for the horo position... which is awesome if your lazy.. just lay plate steel up there and come back in 10 minutes...
as with alot of Grizzly accessories the one it's set up with is pathetic... single thumb screw, 3/4" wide, etc...
gonna drill/tap the other side, fabricate my own that's much wider, stout, etc...
well, I was glad I gave it a once over.. the belt is in tatters...
looks like it could fail any time.... it deserves some maintenance luv, certainly earned it's keep... 
so I go to Grizzly and order a belt... while i was there I checked into, and ordered the top graphite mat that runs under the belt... $11.... mine is completely worn out in the center and definitely affects how true long sanding can be.. i have to take precautions currently...
so expect a bit of this project thrown in over the next week or 2....

still prepping those parts.. did weld up the washer/tube pieces tho...
the big nuisance is I have to shave the vertical piece in the "T" bar, to less than 3/8" of the fingers for a good squish... my kingdom for some 5/16 flat bar right now.. so I'm kind of poking along patiently, trying to get the sander to hog some material, fitting stuff up. the new 24 grits should be here saturday..
but I did mock up and cut the plates for the sander platform.. 3/8 x 6" x 9" top... and 3/16 on the side mount plates....
it will tilt up/down 45 degrees... 4 bolts, 2 fixed, 2 pivot...
part of why I'm pushing this project along, is that I want to get a good repeatable way to do the finger points on the brake....

had the sanding belts show today, so i was able to shave that T plate down good...... here it is tacked up for burning in tomorrow...
here's the lone bolt the machine had....
me, set up on the other side with matching plate...
drill/tap... set up the 45...
tack in main plate....
tomorrow, i'll burn all that in...
that's the way the sander will stay, no side disc stuff, exposed V belt..
and for clarification, the V-belt was what I was referring to being in tatters..... new one should be here in the next day or 2...

got the sander shelf done, it's awesome...
for the lazily inclined........ #autofeedFTW
#Kaibomb
which helped make the squish bars.... the idea being it would be nice if the squish plates helped with the load by being tight to the "T" bar at the top...
tomorrow I'll clamp that whole sammich together and drill the holes to be tapped..

Looks like that will hog some metal for sure.
found the lathe belt, back up and running.... 
it was upstairs under my desk/feet, when I was researching pulleys...
my drill rig... decided on 6 bolts... drill all 3 plates up to tap size.. than take apart and oversize first 2 plates...
you'll have to excuse the mismatched bolts, I'm gonna pick up some flanged stuff.... but the proof of concept works killa...
tomorrow I'll burn in that top round guide... and see about the tubes and posts...
I still need to point the smooshies, but that should be much easier now with the sander table.. I also could conceivably shorten them up a bit too...

oh, just a couple other notes for my remembrance/sanity...
found a 8" x 2" scrap of 3/8" strip steel, gonna add that to the top of the "T", before putting that ring/retainer on.. why not, reason I kept all these scraps around.. easy peezy, burn it..... this thing should bend 3/8", no issue...
also on the actual press.... got a slick hand pump handle storage deal gonna happen soon... still working on the on/off knob potential solutions...... but I'm actually content with just the air handle hose routing/hanging at this point...

ready to do the posts and weld the tubes to the "T" tomorrow......
obviously the posts will be trimmed down after... just need to figure a good way to line it all up...
I'm really thinking I may bore the 7/8" holes in the lower plate for the posts.. sink em part way thru and plug weld em... more work, but a little more controllable..
oh, the other thing I'm going to do is when I get to doing the smoosh points, I'm gonna cut one of the 6" wide's down to 4" and 2".. that way there will be a 6", 4", 2" and 2 3" ones...

proof of concept junk.... please excuse the grainy arse vids, need to work on that...
3/16 x 3" to about 145 degrees..
1/4" x 3" wide to 90 degrees....
I'd imagine it'll do 4" or maybe 5" wide......
bit disappointed, IT DID NOT LIKE 3/8"...
I tried a piece of 2" wide and got it about 35 degrees and said, fug ya...
and it was strictly in the jack.. even hand pumping it... my junk is fine... I didn't push it to bypass point, but... i'm sure it would do 1" wide tho....
I'm confident tho it would bend whatever width 3/16's I want to tho.. 12" wide, etc..
here's how i mocked up the tubes.. spacers, etc...
decided to drill a 5/8 hole where I needed to weld the 7/8 rod to.... that way, my nice machined end would hopefully give me a near vertical post...
tomorrow I need to finish the fingers.... it works out well on the new table.. by the looks of the SWAG pics, it looks like I wanted them more than 45 degrees..... i did not want them to a point.. it's about 1/8" wide at the tip... think the angle is like 55 to 60 degrees... other than 90/45, just set it and clamp...
#freakeyeKaibomb
I'm very pleased.... it all seems to have come together and works very well, smooth.. thankfully..
a big plus is it's all separate.. I can make a single upper press if I want and slide it right on those posts... and loading/unloading it is easier...
the one thing that did not work out optimally was the height... in those vids, the ram is running in the lower 1/2 of it's stroke... basically i need to run it down 2 to 3" to engage... i can just throw spacers in if i want, but I think I may actually drill 4 dedicated brake pin holes in the tower legs for the press brake.. I'll see.. it's not the end of the world.... but when I went to do the 3/8", I wondered if I would get better power at the beginning of the stroke...
oh, one other project i'll be working on in The LAB™ over the next few weeks is an actual decent table for the bandsaw in it's upright position.. 1/4" or 3/8".... the sheetmetal thing it came with is pathetic... I'd really like to start using it that way now that I got a reasonable TPI blade in there...
tomorrow the press gets the handle holder installed too...
3/16 x 3" to about 145 degrees..
1/4" x 3" wide to 90 degrees....
