star plate 13mm x 110pins

[zan89]

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.

Material cost me 65 euros..and lots of hours! :-)

That is a pretty hefty surface area, what kind of press are you using?

[zan89]

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.

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.

I always use dextrin for binder and water/alcohol.

Looks good, zan89. Lot of labor of love in that plate.

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.

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.

Thanks for info.
