my experience is in drilling tools however, can you tell us what kind of connection BX , RX , hammer union? Considering the amount of time it takes to develop a weld procedure it may be better to continue searching for 5L material.

Has anyone seen these aluminum drop hitches? Thoughts? Looks like fatigue waiting to happen, am I wrong? https://www.trimaxlocks.com/shop/tow-hitches/adjustable-tow-hitches/razor-xtr-locks/aluminum-12-adjustable-hitch/ https://www.weigh-safe.com/product/weigh-safe-drop-hitch/

It is .01 inch(.025 mm) thick and it is C26000 brass alloy.

I'm looking for an equation or way to calculate time versus temperature in annealing. The goal is to use the shortest time possible(flash annealing).

Nace 0175 is a material spec not a coating spec, the hardness should be done before coating. You should be able to be within hardness range with 4140.

sorry, i need to clarify. We are getting cracks from the quenching itself. From the thermal expansion and contraction of the quenching process. Delta T is 1650F.

I'm new to FEA but i am doing an analysis on stresses induced during heat treat quenching. I have been using a load on the entire volume of the part and have a temperature constraint on all the surfaces of the part. I adjust the load until i get the correct delta T. I'm not sure the...

What are you dehydrating? Instant coffee is sprayed into a vertical tube with hot air, some products are dehydrated in a vacuum so that there is no heat.

Kawasaki was one of the engines i considered. They have a single cylinder water cooled and they do have twins that are fuel injected. I'm also looking at a two cylinder kohler diesel that has good fuel consumption, weight is a bit heavy though. Now i need to find a engine dynamometer in...

How would you guys approach this problem? Does anyone have fuel consumption data for engines in this size range?

I'm buiding my version of the "Edison 2" my conservative calculations tell me i need a 15HP net. I'm looking for the most fuel efficient engine possible in that range. Most motorcycle, ATV, snowmobile, engines are built and tuned for power not economy. But i have considered an ATV engine.

Is there an engine that is in the 20HP range that is already fuel injected? I'm looking for a fuel efficient engine.

I'm looking for a electronic fuel injection conversion kit for a 20hp single cylinder engine. Does anyone know where i can buy something like this?

We have a weld assembly that falls under API8C, it is load tested then MT'd. If it fails the MT it is weld repaired because it is welded it has to be reload tested. This goes round and round causing fatigue, what should we do? Has anyone else encountered this situation?

I spoke with a research engineer at Southwest Research Institute, he didn't recommend using straight vegetable oil because the combustion causes contamination in the lubrication, he called it polymerization. In addition to that palm oil is much thicker than most vegetable oils. I would...

That's great advice, I'll look in the ASTM A182 that our metalurgist gave me.

I have a similiar problem. I need either a min or max hardness for austenitic stainless steel and cannot find it in API6A. The only suggestion i have had is to use the same hardness that is used for the rings. What do i put on the drawings?

Does it sound like a tapping? We have a similiar engine and it does the same thing, it has alot of hours on it and i think it is normal.

Have you considered moving to Houston? The oil industry is still booming.

2nd Battalion/8th Cav. Regiment 1st Cav. Division, but I've moved on since then. Now I'm an engineer in the petroleum industry.
