Yeah, That’s what I meant... it is only for aesthetics, since brass is not hard enough to retain an edge... but it is beautiful to use as bolsters or guards...

There’s a technique called dambrascus, and it consists in heating the steel to a yellow color, then submerge it into a crucible with molten brass. The liquid brass enters through the pores of the steel and bonds with it... I read this in a book, but never tried... if you give it a shot, please make a review... cheers!

Well, thats odd, here the video seems to be ok.. I’ll try with another vid. I’ll check that 0C8C2EB2-F00C-4850-B5AE-0C7996EA9708.MOV

Hello everyone! My name is Andre, I’m naturally from Brazil. I am finishing my kynion style pneumatic hammer but I’m having a low bpm problem and I don’t know what is the main cause, since I have a 250L compressor running with 15bar.. this is the compressor. My piston is kinda big, but I don’t think that it would be a problem to this compressor... it has 115mm on its base, and the arm diameter is 45mm ( don’t know if this is the right word) Ive based myself on crickets air circuit plans, but with only one roller valve ( maybe this is the problem) (This is not the pilot valve I’m using, it’s just to use as example) All of the main connections and the pilot valve are 1/2”, only the roller valve and it’s connections are 1/4”. Here is the video of the hammer running... I’m hopping that someone will be able to help me! Thank you!! EA206319-0C77-4302-88C0-722A26E5780E.MOV
