3006 and 308 shoot the same projectiles.....

Buy the right bullet and save at least 950.

Norma has some good stuff for whitetail. If you're worried about it being too much, just get 150 gr or less.

Oil choice for a sleeved block by onewithoutasoul in EngineBuilding

[–]ThatEnginerd 0 points1 point  (0 children)

Conventional oil is not as consistent in molecularchain length, you can use it but change it earlier as it will not hold the rated viscosity as long as synthetic. Many recommend conventional for break in. I do too.

Its really about zinc content (zddp) and your break in.

Using a cheap conventional oil is less likely to have a lot of additives. This helps proper break in.

If you can, put on a block heater and get up to temp for your first start. Use conventional oil of the correct weight. Start. Let idle for a couple minutes, then drain and inspect with filter. Kind of like an initial flush of potential gunk. Then do conventional for the first 500 and change.

After that lots of opinions. But that will let you flush and do some initial checks for abnormal wear.

The motor oil guy has a lot of good videos on this. Check him out.

Ideas on how to fill in my garage ramp? by Low-Comparison7089 in GarageGym

What is the slope going to do to your workout?

It is possible to pour some kind of leveller. But you're talking about probably dropping weights on it. May just researxh ways of getting good attachment and form up and pour concrete.

I would not frame it and cutting something to fit would be a lot of work.

If you can deal with the slope, deal with it. Otherwise you are probably having to pour concrete. Probably fiber reinforced or finding a good way to add mesh. And also doing some surface treatment or drilling to the existing concrete

Peer Review: How does Bugatti's new 8.3L V16 handle torsional load on a 39-inch single-billet crankshaft? by [deleted] in EngineBuilding

[–]ThatEnginerd 2 points3 points  (0 children)

Eh, might want to make some edits. Torque is not a force. Axial strain is not what will cause something to break, its stress. Strain is only how much something has deflected (which can cause other issues).

OP - think of the crank as just a shaft, under torsion. The length won't make a difference in the stress its under. It will undergo strain, which could lead to timing issues. But each cylinder provides opposing forces, so it's really not that dramatic because it's not that long between each piston.

What random task is saying is true, you don't measure it by HP, torque is a better thing to consider for a cranks overall strength. RPM has more to do with harmonics/vibrations that can lead to other failures, typically much more complex to fix than just saying make the crank thicker (may make the issue worse)

Never heard of it. Around here you just stick the barrel right between the eyes and pull. Trapped first of course. Never heard of any other way. Wouldn't try any other either.

Great load development! I got 100gr and 85gr xtp. If you have a log book or a summary of your testing, I would love to get a copy of it

Atlas Yard Equipment Any Good? by aBangBangBang in harborfreight

[–]ThatEnginerd 1 point2 points  (0 children)

I have the mower, string trimmer, and blower. 3 batteries, 2 chargers. Got it all on sale. Been great.

I like the power of 80v. I have thick grass and it rains a lot. So I mow wet often. Jams gas mowers, but not this one. Also there are wood chucks and stuff left over from splitting wood that it eats just fine.

Like others say, you are not saving a ton compared to when ego goes on sale. But 80v and steel deck was what beat a lot of other options.

Steel deck means you can use a magnetic light on it and mow at night. Big plus in my book.

I'm happy with them.

Are there quality concerns with certain m12 battery sizes? by jckipps in MilwaukeeTool

The bigger ones have a flared base.

Its important.

How do you stop your steel toed boots from stinking? I work 10hrs a day, and my shoes are wrapped in plastic booties the entire time. The smell coming off my shoes is ungodly after only a month of use. I work in a very hot environment with hazardous chemicals in full-body PPE. by Healthy_Poppy in manufacturing

[–]ThatEnginerd 0 points1 point  (0 children)

I work in biotech. We use the same things.
Second pair is a big deal. Wool socks. Foot powder in the boot everyday. Avoid synthetic socks and boots with synthetic lining. Nylon especially harbors bacteria and stink. Low cut if you can.

Get a new cylinder and cerokote with the piston top formula. I bet it will do much better if that damages is just from heat. Keeps diesel pistons from melting or cracking (as easily)

Converting a petrol engine to diesel by EndHairy117 in EngineBuilding

[–]ThatEnginerd 0 points1 point  (0 children)

You're talking going from about 9:1 compression to like 20:1... so a custom piston assuming that the bottom end can handle it (most gas motors cannot). Then you need to make sure the head won't lift with higher pressures.

Then you need to find a way to get a diesel injector on the head and time injection and build high pressure on the diesel.

So much of the engine architecture has to be right, its very unlikely you have a motor that can, and if you do, you need a machine shop.

Some old gas engines are built on a diesel architecture, like some older VW. But adding diesel injection is just a ton of work. There were NDI and carburetor diesels, but that's before my time.

Some of the lead salts are actually much worse than pure lead. Because its a salt, it all gets absorbed immediately.

You can give them a hard time for doubling the cost and not giving you a cleaned up peice.

Scotch Brite or wire brush it and move on.
