UP, What is the distance from the top of the ram to the bottom of the top plate with the ram in it's "up" position. I want to use this press for reloading as well. Tks ahead.

Here are the Dimensions from the bottom of the top plate to the top of the ram are.Originally Posted by 20nickels
Ram Up , Ram Down , Travel,
Swaging Mode 5.000" , 8.000" , 3",
Reloading Mode 3.500" , 9.500" , 6",
im in the process of designing a 3 column version of this press specifically for reloading high precision 50 bmg loads and swaging 50 bmg and 458 socom bullets...
this is a rough sketch thus far... will give details out when I verify this beefier press will work out ok....
once we get the ball rolling with this monster and Upnorth confirms the design we will try to get a group buy together possibly...
^^ I would likely be interested in a group buy pending the details of course. I'm interested as to how you arrived at the changes in the original design. Was there some play or flexing? I can see how the ram would run true (truer?) with more steel supporting it.
Trey came across the design some place else. Your question on the flexing issue, there has been nobody that has reported any flexing. He wanted to know if I could build a three post press with a heavier toggle if he deigned it. The price on this design is a unknown as of now ,pending a materials list and cost of labor and shipping.
I have not heard of any play or flexing as well. I arrived at this design based on a mixture of an italian made reloading press designed for sizing and reloading 50 bmg without even .001 of runout... I wanted to mix the high precision and very low tolerances/ thick metal design of that press with the swaging press on this board... allowing me to swage up to 800 gr 50 bmg bullets and even 600 gr subsonic 458 socom bullets.... Ive really only seen people using hyd. presses for such work, but Im a simple man, I would like reloading tools that dont rely on electricity to tun... kind of an off the grid mentality, lol...
it will indeed be a monster press!
Anyone who can design and build that press is hardly a "simple man".my hats off to you nice job!
You need a good sturdy table for that thing. How much does it weigh? Nice press!
nice looking press U.P. North
Doc.
That yeller press in the top pic looks like it would take out your hip walking by if you didn't see it sticking out in to the room, lol.
I'm sure UP's press is precise as is but overbuilding rarely hurts. To me more steel is only an issue when shipping and purchasing.
Looks like they have some sort of adapter in the ram. I think a LNL conversion bushing, if possible, would be a real time saver
UP North,
Will your press swage 50cal? I am interested in a press
for the 50 BMG.
Thank you Sir,
Barry
I guess I can see how a three pillar press might be sturdy where the force to drive the ram is on the base plate and not the top plate, but in UPNorth's original design, where the toggle force is transferred all the way up to the top plate, I don't think a third pillar will add anything. I note that in all the presses shown you are still only using two rods to guide the ram. The third would only serve to locate and strengthen the top plate. An issue that does not appear to matter in those presses that hang the toggle from the top plate. Am I missing something? Not to say that heavier material won't apply more force, but I just don't see the purpose of the third rod or pillar in this design.

"let's go. He ain't hittin' nothin'.".... "You IDIOT, he's hit everything he's aimed at!"
bfuller, yes His original design has 6" of travel, with the proper ram and top plate threads for using ch4d, rcbs, 50 bmg dies and adapters...
mightThor. Like you saidI think it will be a stronger design to keep the top plate and full sizing/seating dies more securely positioned, especially where the force for the ram movement is transferred to the top plate. To me it would make a more precise tool especially in this type of design. Not to say the original is bad, but at least Ill have piece of mind knowing the top plate is not gonna tweak or move now. The extra material on the baseplate will also help keep the ram located more precisely on its upward travel...The third would only serve to locate and strengthen the top plate.
This design utilizes the 3 colums as guides to support the guide plate...

This design makes more sense to me as far as what you were talking about. Three guide rods would certainly minimize any rotational misalignment that might occur on the ram. Still don't think it will alter the force on the top plate because that is all located at the die hole and where the two arms attach. Still, if you want it, build it. should be ubber strong.
"let's go. He ain't hittin' nothin'.".... "You IDIOT, he's hit everything he's aimed at!"
still messing with the design...
Might, no this will not have any effect on the amount of force transferred to the ram. that would take place at the toggle. I'm merely taking the original design, and beefing it up for higher precision.

I re-came across this thread...and I think this press just may become next year's Christmas wish list.
Come to think if it, it's rather amazing how much money and time I'm willing to invest to avoid buying commercial j-words...
howcome your not out walleye fishing ????? the kid called just befor noon and had 5 eyes a 2 pike . he is fishing the dead riverand im stuck in a shop down here... you guys in gods country have it made !!!!!!!!!
to treysoucie,
are you planning to build and sell some of those beautiful three post presses? if so, what do you figure the price will be? I'm not scared of the price, i've been swaging for 30 years and have learned to appreciate the beautiful machine work and tallent that goes into the tooling that this hobby demands.
what type of steel are they made of? if you don't plan on building any for sale, would it be possible to get a set of plans for them?
thanks,
luober
Is Tim aka up north still around. I cant reach him by pm.
