Any ideas for a very rigid, hard coating that can be applied by conventional methods? the coating would also need to be fairly high in viscosity to avoid saturating the core material. The application is a propeller blade 7" long by 1" wide and .040" thick. To put the loads in perspective each...
I am having a hard time getting my head around this concept and if it would even work and was hoping a sharper mind could help. I have seen it work by driving the sun but can it work by driving the ring. In this example (see attachment) the drive is in yellow. A propeller is attached to the...
Good day Gentlemen,
I need some help selecting a grade of hot work steel or other variety that will survive in this environment.
Application- Nozzle for extruding abrasive plastics at high temperatures. Nozzle measures 3mm long X 1.5mm in diameter with a through hole starting at .75mm then...
I hope I am not braking any rules by linking to my original post but think this may have been a better place for it. Please take a look

I appreciate you taking the time to read this and will attempt to keep it short. Engine Tips is my go-to when I'm stumped and I'm about stumped
I am designing a miniature planetary reduction unit based off of the friction drive concept. The unit will be driven by a <35w electric motor via the...
A need in my particular field of interest exists for a tuned pipe/muffler (for IC engines) that has very low thermal conductivity, mild to moderate strength, good thermal tolerance (1600deg.F) and be relativly easy to manufacture. Typically aluminum, steels or carbon fiber w/ a BMI matrix are...
I will apologize for my ignorance in advance.
I am interested in locating a high strength, high impact tolerant, shaft material 8-10mm in diameter, preferably precision ground to fit bearing. This will be used in a fixture to conduct destructive testing.
test example-
-8mm shaft
-about 6" in...
I need to come up with a horsepower gain/loss percentage for changing density altitude. This piston engine is operated from 500-3000' DA, produces approx. 3000hp from 520 c.i., has forced induction of approx. 45psi manilfold pressure, consumes around 16 gpm of methanol @ 10,000 rpm.
A fairly...
The vibrations created primarily from the power pulses on single cylinder 2- stroke engines (or any single cylinder) present a problem in my application at idle and low rpm mainly. Soft engine mounts have been created to combat the vibrations with some success. Although the harmonic dampers that...
New member here. Like to first start by saying hello and also to mention how excited I am about finding this web board and I have high hopes for this knowledge pool to steer me in the right direction. I am developing a electronic engine management/fuel injection system to use in our 30-40% (of...
