I am trying to do things on my cell phone and make mistakes.

This made me run out at this time of night to snap a photo of my jars of bolts.
Notice there are still some baby food jars.
So long ago it seems…
Today the boy said to me I should take it easy.
he’s scared I will fall off a ladder trying to cut down trees.
Im in a battle with the False Acacia trees that are over running my yard.
( dam invasive tree )
FYI:
In 1960 when this house was built there was not a stick of wood growing around here.
NOT a single tree…
Acid rain killed everything, even grass was hard to grow.
What a difference 60 years can make.

Good information. I have seen people use it as nozzles. The youtube guy for the glass was just cutting up a grinding wheel, and supposedly used that, but that doesn’t mean it didn’t fall apart after the use either. plus they do let it cool all the way back down, so it might liquify a little and reform. I don’t trust everything I see on youtube. but it is pretty similar to the melting aluminum in a microwave. I will have to go back and see what they used for that. I was thinking they just used the microwave crisping foil, but that could be wrong.

Apparently reading and rereading on this a bit more… silicon carbide is used as a susceptor, for metal melting apparently they also use a magnetite/graphite (magnetite works better at higher temps) and graphite paste painted on the crucible. Should I just try an old motor magnet and coat/paint that with graphite to heat it up? I’m not finding much for SiC except grinding wheels, dressing stones and sandblasting media.
I did find one something that used the blasting media mixed with waterglass as the susceptor for the kiln. but waterglass isn’t cheap but it is
Apparently glass will melt on it’s own in a microwave but it works a lot better if you preheat it. 
so maybe just graphite would work.
Honestly, if you wanted a quick way to make a handful of char to prime your gasifier, or you need a carbon rod for an arc furnace. i’m guessing you could get this to work. Im not sure what you do with the off-gases… but …

I thought this might interest some. This is the auger I use for planting. I start my plants in cell trays and when they put on leaves I move them to 8 oz styrofoam cups. When they are well established I put them in the ground. This auger makes a perfect size hole for the plant. If you are planting tomatoes then it lets you quickly go deep enough to cover a good length of vine. I have other augers as well, but this one is the best I’ve used.

Hi Folks,
I like to make cardboard models before I cut and weld. I just think it makes everything easier. The little triangular piece of wood in the picture has a hole drilled through it and a pencil in the hole. It allows me to make a projected line on the cardboard. When i made the curved hopper tube I projected the curvature of the bent pipe I scrapped from something else. Then I wanted to make two 45° turns in the pipe instead of one 90°. When you make a 90° turn you cut the pipe at 45°, and the two cut pieces add up to 90°. Simple. So if you want to make a 45° turn you just set your mitre saw at 22.5° and cut. Ask me any questions.

I’m intrigued by the pencil triangle dohicky, but i dont get how that would work.

Okay, Let’s imagine I wanted a silhouette of this vice jaw. It doesn’t touch the cardboard all the way around.
Not perfect, but the pencil/triangle quickly gives me most of the lines I need without guessing. It will be fairly easy to rough in the remaining lines.

That! Is a very good idea

Rindert, didn’t old Speed Squares have a hole for a pencil? Or maybe that’s something my grandpa did for drafting.

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

Now i get it. And im gonna have to make one, or three.

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.
