zan89 Posted March 7, 2015 Posted March 7, 2015 (edited) Hi!Because i didnt like slow procedure of making stars, i decided to build star plate from scratch. I bought 2 alu plate 20x20x2,5cm and alu 13mm x 5m stick. I cut the stick in pieces 42mm long, dril 110holes 13,2mm in diameter. I was driling bouth plates at same time.It was lot of polishing time of every piece.http://shrani.si/t/s/gX/5iyerO8/20150307211858.jpghttp://shrani.si/t/16/xB/3I1RfPSn/1/20150307211954.jpgMaterial cost me 65 euros..and lots of hours! :-) Edited March 7, 2015 by zan89 1
nater Posted March 8, 2015 Posted March 8, 2015 That is a pretty hefty surface area, what kind of press are you using?
zan89 Posted March 8, 2015 Author Posted March 8, 2015 Ill try with 10t press. If it is not gona work i will try then with 75t press.How much you think i will need to prees that good?I will use it end off the week.
Arthur Posted March 8, 2015 Posted March 8, 2015 I think you may need the big press for that, depending on whether or not you use a binder and which one you chose. With enough force per star most comps will compact without a binder, if the force isn't enough then you will need a binder and a little water. Don't use titanium flake or sponge or turnings in an alloy tool the tool will be damaged quickly.
zan89 Posted March 8, 2015 Author Posted March 8, 2015 I always use dextrin for binder and water/alcohol.
Bobosan Posted March 8, 2015 Posted March 8, 2015 Looks good, zan89. Lot of labor of love in that plate.
Mumbles Posted March 9, 2015 Posted March 9, 2015 Good luck. The 10t might work. It will deliver a force on the lower end of what I generally see recommended, but you never know until you try.
Carbon796 Posted March 9, 2015 Posted March 9, 2015 If the 10 ton press, puts out a true 10 tons of force. You would get approximately 856psi on the comp. Which should be fine, I've pretty much standardized all of my star/comet pressing to 500psi on the comp.
