Tim1877 Posted September 20, 2017 Posted September 20, 2017 What size press would I need to press 4x4 star plates 3/8 to 1/2 in stars?
OldMarine Posted September 20, 2017 Posted September 20, 2017 You can use a 1 ton arbor press for those but I'd recommend getting a 2 ton since they aren't much more and you can eventually press ¾" BP rockets on it as well as comet pumps.

OldMarine Posted September 20, 2017 Posted September 20, 2017 (edited) I bought mine off Ebay but it is nearly identical to the Harbor Freight model. I haven't finished modifying mine but it's an easy job. I just haven't got around to it. I have it sitting on some metal plates and it's braced against a ceiling joist which gives me plenty of pressing power for what I've been using it for right now. Here's the thread on mine and the advice I received:http://www.amateurpyro.com/forums/topic/12222-2-ton-arbor-press/One other note: Caleb sells a 1 ton with the modifications already made. Even if you decide to get the 2 ton a look at his will give you the gist of what you'll need to do.http://www.woodysrocks.com/store/p142/1_Ton_Arbor_Press.html Edited September 20, 2017 by OldMarine
MrB Posted September 21, 2017 Posted September 21, 2017 Now, full disclosure. I don't use, and never have, an arbor press. That said... Would a 1 ton press actually be sufficient for 4x1/2"? We are looking at almost 0.8 in2. I suck at force to pressure conversion, but it "feels" low to me.
OldMarine Posted September 21, 2017 Posted September 21, 2017 Caleb made his small plates to be used on a 1 ton arbor press and I've actually had success pressing with the little ¾" model I got from him.
starxplor Posted September 21, 2017 Posted September 21, 2017 The plate I also got from Caleb works perfectly in my 1T press. Stars come out well compacted and burn cleanly once dry.
MrB Posted September 21, 2017 Posted September 21, 2017 As long as it works, who am i to argue against it.
starxplor Posted September 21, 2017 Posted September 21, 2017 I would not suggest trying it with a plate the size of a sheet of letter/A4 paper, but the small 'handheld' size plates seem to work.
