I don’t know what a speed square is. But I’m pretty sure I’m not the first one to come up with something like this.

Many new speed squares have a pencil hole at 3 1/2 for quick scribing width of a 2x4. I prefer the swanson brand speed squares for this reason they have notches on the small square for quick scribing and full pencil slots on the big square for beam work, extremely handy for metal fabrication to minimize use of a tap measure savings seconds while using one tool instead of 2. Efficiency! can you tell i was a framer? 4 different squares live on the fabrication table

Same, I’m gonna need to make a Scribe one for sheet metal, a Sharpie one, and a Pencil one.

Neat things I’m discovering with my Chinese inverter welder.
You can’t accidentally use the wrong polarity in Flux Core mode, it just won’t strike an arc.
Out of all the stick welders I’ve had, it strikes the best arc. I’m still figuring out the sweet spot for 3/32" rods without blowing holes in stuff. I can finally get some practice in for stick.
They’ve upgraded the model, I have the MIG140G and now they’re on the MIG140M. Mine lacks an LED display for my adjustments so it’s just figuring out the sweet spots.
Tolerates 50hz electricity apparently, I shouldn’t be surprised. Runs on 120vac or 240vac, it comes with the very Chinese 240v adapter that just daisy chains to the 120v plug. I’ve yet to trip the duty cycle shutoff.
Edit: The mod I did to run 10lb spools will work with the new model based on images of the product.

Since you are doing dc welding. This might be of interest:

I was looking at the el cheapo plasma cutter combo until it was pointed out how far it throws sparks, and i needed a safer place to do it.

Does anyone know if the ‘jumpstart’ small engine drill adapters have the one-way sprag bearing? I have a couple of small engines I need to do carb and fuel line work on and those adapters are 10 bucks. The engines dont have the jumpstart feature. Otherwise I am looking at having to make something from like a starter gear. Or killing myself trying to pull start them.

The few times I’ve drill started an engine I didn’t have a sprag clutch, wish I did though. It spun the chuck off of my power drill every time.
You can buy 1 way bearings on eBay for pretty cheap, I got some to make pedal starts for motorized bicycles.
I used needle roller bearings for reference.

They are in some (if not all) automotive starters. which are about the same price as the bearings that came up in my search. Somewhere around 20 bucks, but I can get the jumpstart thing for 10 bucks from lowes right now. But I guess autozone is open now too.
I am kind of surprised no one sells one. It must be a liability thing.

Just from a quick search I could only find the ones made for TroyBilt string trimmers and other small engines made for them.

that is all I can find too. I am just surprised. And that looks like it might break turning anything over larger then a 3hp engine, or I just have little faith in some tools…

You could always copy the old hand crank style engagement.
As the engine spins it’ll push it away.
Just realized you’d need to add a mirror image of it to the flywheel side. Dang.
Could just ride the lightning and chuck an impact socket on a drill.

well there is this one:
But it is 339.

You might be able to find a rubber wheel that chucks into your drill, and bump start the engine. It would need to run in reverse.
Or try this

I might try one of those if I can’t find one with a sprag in it. One video said sometimes the direction lever flies out of position from centripetal force which locks it, and you might not notice it.

Here’s another one where a guy used a sprag from a Chevy starter.
For a Counter Clockwise engine like a Honda.

I saw one like that. I might just get the racheting thing. I have motors that spin both ways. It will be the easiest. And probably cost the least overall unless the rachet locks and I end up in the hospital. Thanks for encouraging the Amazon to come to the door

Why not just use an air impact with a pin locked socket?

Unless i am missing something what is the problem ? in the early days of starting engines on wood gas i always used a standard socket 17 or 19 mm onto the nut on the crank i have never had it fly off although it did once stay stuck on the nut but came off the short extension bar i was using , maybe try using a worn socket so its not so tight on the nut .

Yeah, I couldn’t understand the problem either. Actually it was Dave that told me I could start my generator with a drill so I pulled off the recoil starter and cut down a 15/16 socket so that it just bit about half of the width of the nut. Welded the socket to a half inch drive extension and turn it with a 1/2 inch HF drill motor. Never had any problem. Thank God, because getting that generator to start on wood gas by pulling on it is a fools errand. Work yourself to death just using gasoline sometimes.
