Spanners Posted August 4, 2008 Share Posted August 4, 2008 HI all. I'm doing a reset on my tool head, and based on the Dillon manual, its states to raise the platform and screw the sizing die down until it douches the shell plate. With the handle allt he way down, it feels as if the press is camming over a little. With the die set as per the book, at the bottom of the stroke, its is a very mushy feel as press cams over... almost like a heap of flex also.. To get rid of this, the die has to be wound in approx another turn. I can't see this being of any issue, althoguh I thought I'd ask 1st Link to comment Share on other sites More sharing options...
warpspeed Posted August 5, 2008 Share Posted August 5, 2008 What caliber ? Never had to cam over a pistol dies and have yet to not cam over a rifle. Did that make sense ? Link to comment Share on other sites More sharing options...
HSMITH Posted August 5, 2008 Share Posted August 5, 2008 I ALWAYS set the sizing die up so that it cams over, but it should be pretty minimal, shouldn't feel like you are flexing the press. Back it out until it clears, raise the ram fully, screw it down until it touches, lower the ram and screw the die down about 1/16th of a turn. Raise the ram, repeat the 1/16th turn as necessary until you feel the toolhead go solid, at that point you are done. With the ram fully raised lock the die down.

Spanners Posted August 5, 2008 Author Share Posted August 5, 2008 Caliber doesn't matter in this instance as the press camming.... there is no NEED to do it for production, it more the issue of camming not being right? HSMITH- The manual states to have clearance, althoguh it doesn't feel right when running the press.... but screwing the die to the toolhead; that goes against he manual (no issues there) BUT it also takes any cam out of the equation, which I think is the right way (as per a single stange press setup) It just feels wrong! Dillon - anyone esle Link to comment Share on other sites More sharing options...
HSMITH Posted August 5, 2008 Share Posted August 5, 2008 It is my opinion that manuals are written for the densest customer a company can reasonably expect to have. That guy will set his press up to cam over HARD and flex the heck out of it if the manual says to have it touch. He will wreck the press in short order. Have a little clearance and the press will work OK for everyone. But, with pistol ammo I want the sizing die absolutely as low as it will go, as a side benefit I don't have OAL variations from full shell plate to partial shell plate, I don't have any use for the toolhead clamps, and my ammo is as consistent as it can be.

Spanners Posted August 18, 2008 Author Share Posted August 18, 2008 I've stripped my pres a few times, tried different calibers and toold head.. its still caming over at top of stroke... or flexing when loading. I've orderd a strong mount and will see how it des.. it never did it when I 1st got it, so hopefully its just the bench getting old. Link to comment Share on other sites More sharing options...
Front Man Posted August 18, 2008 Share Posted August 18, 2008 With the die set as per the book, at the bottom of the stroke, its is a very mushy feel as press cams over... Check your bell crank/bell crank stop. (My terminology) I'm on my third one in 3 years. And I don't shoot/reload much. The original crank lasted for years and I shot a lot back in the day. Maybe I'm getting stronger with age! FM Link to comment Share on other sites More sharing options...

Howard, if I understand your procedure the die is now set so that on the downstroke it goes farther past the point where it touches the shellplate? Do you do this for 1050s as well? I have always set them up as dillon states and I now have a newer die that does not size far enough. It came with my new 1050 and I was getting ready to contact dillon on this but I will try this setup and see if it adds enough stroke to take out that last little bit. I am surprised by how much their dies vary. Link to comment Share on other sites More sharing options...

redwoods Posted August 18, 2008 Share Posted August 18, 2008 What does camming over mean? I have a 550 and have no idea what camming over means. Thanks, Randy Link to comment Share on other sites More sharing options...
D.Hayden Posted August 18, 2008 Share Posted August 18, 2008 Look at post 3.. Howard describes it.. Basically.. after the die is touching the shellplate, the ram continues 'just a tad'.. Link to comment Share on other sites More sharing options...
larry cazes Posted August 18, 2008 Share Posted August 18, 2008 (edited) Larry,Careful! 1050 Shellplates = $$$..... Yup, in the past I have been concerned about damaging the shellplate. This is why Dillons instructions have always made sense and until now I have never had an issue with a die not sizing sufficiently. I guess there should be some small amount of spring to the shellplate and as long as the SP never bottoms out hard, no damage should occur?

Spanners Posted February 1, 2009 Author Share Posted February 1, 2009 Update from a new months ago.... Have strong mount.. no difference.. with the die not touching the shellplate, I get the cam over feel.. sigh... Maybe I should drilla nd tap the stop and put a bolt with lock nut on it to limit the travel a touch? Link to comment Share on other sites More sharing options...

Maybe I should drilla nd tap the stop and put a bolt with lock nut on it to limit the travel a touch? Check your shellplate. Make sure it's tight. Loose one can feel mushy with a cam over. I have mine set with just a little pressure. Not enough to feel any thru the handle, but enough to raise everything and take the slack out of the machine.
