CUSTOMER SPOTLIGHT
CUSTOMER SPOTLIGHT This month we're featuring a project by Joe Geisler, who sent us these photos of the Panther Pup 4 cylinder model gas engine he's building. The cylinder heads were machined from Speedy Metals cast iron. The homemade piston rings are also cast iron. The pistons and connecting rods are aluminum, and the crankshaft is 4140. The engine block is cast bronze, and the rocker arms are brass. He says, "All parts are machined in a home shop."

DID YOU KNOW?
DID YOU KNOW...? ...that researchers have uncovered the secret to stronger metals?
Metallurgists have developed many techniques for reducing the size of the crystalline grains that make up a metal's structure, because the smaller the grains, the stronger the metal. Now, researchers have discovered a "'novel pathway' by which [metal] grains were forming down to the nanometer scale. The new pathway, which they call nano-twinning assisted recrystallization, is a variation of a known phenomenon in metals called twinning, a particular kind of defect in which part of the crystalline structure flips its orientation. It's a 'mirror symmetry flip, and you end up getting these stripey patterns where the metal flips its orientation and flips back again, like a herringbone pattern'". The higher the rate of these impacts, the tinier the grains. When they tried this process with copper, they increased its strength tenfold! The best part? Their findings can be applied right away to real-world metal production. Learn more in the full article here.
