500x magnification, it says.

At 30x, a human hair looks like a 16 gauge wire.

OK so here's what I did. Using the millimeter sides of these rulers, I put one under the "microscope" and the other one on the screen, as shown, and then another pic looking straight down at it.

I count six millimeters on the ruler for every one on the screen.

That's 6x.


But I figured out the problem:

Years ago my trailer cord burned out.

Shop put new air-lines and a electical cord but the fittings were off and it was made in China and he said damn chinaman sweatshop goons cant measure correctly..

He put new fittings resealed it and they worked just fine the month or two before I quit
 
My projector took a shit, and this 65" TV was half what I paid for the projector, and you don't have to turn the lights off to see it.

So now I'm building another little crane for my shop, for the sole purpose of lifting the box off of the TV. 🤓

I had a lot of design requirements.

1. I didn't want to go up into the attic to frame up support for a pulley on the ceiling. It's freakin' cold up there. So that means a crane boom off the wall.

2. If I decide to get another projector, I still wanta be able to use the screen. So the crane has to be able to swing fljat against the wall, behind the projector screen which is 5" from the wall.

3. Gotta be able to lift the TV itself because I don't have anyone to help me lift it up where I'm gonna put it. Sarah is too female, my dad's too old, and my neighbor Jimmy is too dumb.

But the TV box only weighs about as much as a gallon of milk, even with the wood I added inside to spread out the lifting force from the hook.


I have already hung from the crane boom myself, holding onto it at the reinforced joint halfway down the boom where the gusset attaches.

The boom itself is just a 1x4 split into two 1x2's.

Here's the spool part. All I gotta do at this point is screw it to the post below the crane. But I'm gonna polyurethane it first.

Not that it needs to be pretty, but because it'll be easier to keep clean.

The only lathe I have is my grandpa's and it's old and just uses little pointy things to hold the workpiece.

To make this spool, from a piece of a 4x4, I had to literally invent a type of power tool I've never seen or heard of before but probably already exists somewhere..

Cross-sliding drill press vise. Router bit. Temporary axle holder. All I had to do was slowly rotate the wood and let the router bit eat it into a cylinder, moving the vise sideways incrementally.

Then sandpaper. Then put it back in the drill press all sanded smooth as if the router bit made it that clean... 😁

Them dowel ends, the center one pins it to the axle. The other 4 hold the two halves of the spool together.

Before I made the cylinder, first I cut the 4x4 into two 2x4's along the stress line where it looked like it would eventually split. Then I glued it back together, minus the internal stresses.


To attach the end of the rope, I removed the center pin and fed the rope through.. I twisted the dowel til it pinched the rope inside the spool. Holding it tight like that, I drilled a 2nd hole for the rope.

Now with the rope fed through the center of the spool, I gotta twist it & pinch the rope in order for the holes to line up to insert the oak peg.

Oh yeah I shoulda mentioned, raising the box off the TV is so I can watch it.

Lowering the box back down over the TV is to protect it from all the airborne sawdust every time I so much as LOOK at the palm sander.
 
The thrust bearings between the spool and the support brackets...

Discs from the side of an antifreeze jug. 😅

It works. They're really slick. Two discs per side.

Axle bearings are just oak through holes in oak, and a shitload of parrafin wax. I didn't have anything the right size to make bushings out of.

Crank handle can be squeezed down tight on the oak dowel, but I don't think I'll need to. It's pretty tight and I don't anticipate having to crank on it very hard.

Kinda like car engine main bearings, except it's wood and there's nothing but candle wax for lubrication. 😅

Maybe I'll invent a heated grease gun that injects molten wax into zerk fittings. 🤔

I picked up a car battery with it.

But I gotta make a brake or a ratchet mechanism and some way to swivel the crane from the ground.

I've been messing with a notebook, rulers and a compass trying to figure out a good shape for a one-way disc brake, like a ratchet.
 
Could you use the mechanism from a ratchet strap somehow?
I want to make it entirely out of wood if I can.


I've got an idea for how to lock the finished ratchet disc onto the 1" oak dowel without using glue. I want the axle dowel to be replaceable.

I'm thinking I'll tap it onto the dowel and drill a 3/8" hole right at the edge of the 1" circle, so the drill bit eats a 3/16" radius half-circle into the dowel and the inside of the hole in the disc. Then I just tap a dowel in there and it's locked like a keyed shaft.

I've got that sketched in my notebook. Theoretically I could make a splined shaft that way.
 
Found this online. Somebody's decorative kids toy made of balsa, basswood or fiber board..

It's distressing to look at because it's got an odd number of teeth.

I'm gonna replicate this but with 8 teeth so it clicks every 1/8th of a turn.

No complicated measuring of odd degrees.

Draw a plus + sign, then an X on top and you've got an 8 point star. Place it inside a circle, measure half an inch inward from the perimeter towards the center, and for the curves I'm pretty sure the same radius of the outside circle is correct, if you offset the center.

I'll figure it out when I get home.

The workpiece is ready to mark & cut but I gotta figure it out on paper first.

I think I have more geometry tools than an art teacher. 🤓


I've never measured a CD or DVD but it would be cool if it happens to be 5".

Sarah has like 5 copies of "Dirty Dancing" and 3 copies of "Pretty Woman" and a whole bunch of stupid tinker bell Disney movies I can use 😁

So here's what AI thought I was gonna make when I told it to simply "make it a wood cutout"


Imagine_122284041854212595.webp

That would be the strongest way to do it but I ain't gonna do anything that precise. All those perfectly straight cuts, sanding them perfect, while staying in the right specs to line up seamlessly like that... Nah.. 😅

So here's what I got after I retook the photo, making sure the pencil lines I'd erased were erased better so it wouldn't confuse the AI, and it gave me this:

The flipper thing that will catch the pinwheel teeth.

Osage Orange wood.

6 mm tool steel pin, inside a 6 mm brass tube that's 7 mm outside diameter. I didn't have a 7 mm drill bit but I found a letter sized bit that was close enough.

No oil, no slop, & no friction.
