An update. I got so many things going on, things that I have to do I feel like im going to go crazy!!!
I got my one digital caliper in the mail. This is the better one. The other one hasnt come yet! OMG I order that how long ago! Harborfreight.com sucks @#$! Anyways,... this thing is nice! I was measuring the thickness of hair! I noticed that one end of a hair is thicker than the other:) Cool!
And of course,.... it never fails. Something always ends up broken in the mail. They seriously need to rethink their efforts. I mean seriously.
So nice! It's good up to .005 but I actuall think its goo up to .0005! A little "5" shows up here and there after all the numbers when measuring stuff.
Got my Gentec small torch!
OMg it was like xmas opening this thing up. It's got fine tuning knobs for O2 and gas. Comes with like 5 tips numbering from 3 - 7. I know theres a #2 tip but after using the #3 tip I cant imagine using a #2. The flame would be so damn small.
Comes with 8' of hose.
The Gentec next to the MAPP torch.
This right here is the MAPP torch tip. I think its a #7 size tip. Which is the biggest tip the Gentec came with.
This is the #7 tip for the Gentec.
Side by side.
Now this is the smallest Gentec tip. Its a #3 tip.
This is the #3 tip in action. I have it maxed out. I usually use this tip with a lot less gas/O2. Because waving it around while polishing will blow out the flame when you push to much gas/O2 through such a small tip. The flame it mush smaller when you use less gas/O2 than what you see in the pics. But its still hot enough to do a smashing job at flame polishing.
Here I am destroying a piece of aluminum with the #7 tip. so cool.
Look at it glow man,... geez. Now this is a bit different than melting I think. When I destroyed this piece,... I dont think I had the flame as hot as it should of been to melt it. I think I had it just below what it should of been. It's still melted but its like it more or less destroyed the aluminum. From slowly heating it and then continuously heating it,... it like ruined the aluminum or something. This piece had an after glow where another pieces I flamed,... didn't. The piece that didn't melted a lot faster.
This is the piece that didnt have that after glow to it. From what I heard,... aluminum doesnt really get red hot. It does but not really. It's just melts right away. Thats what this piece did. It just looks melted. there the other piece looks weird. I dont know.
some pieces that fell off while melting it. the two on the left hit the floor and the one on the right almost set my table on fire.
My new baby.
Time for some flame polishing. I put the 3# tip back on for the flame polishing. I also made this little handle thing I use to pick up and turn the acrylic. Now the acrylic doesnt really get hot at all when flame polishing! thats exactly what you want! Its perfect.
Ok heres the before.
Here's the after. This is actually stage one of the polishing process. I actually had to flipp them after they cooled to do it again. They came out great.
This is what I got done before running out of O2. Melting the aluminum and farting around on video used up a lot of O2. No sanding here.
Ok,... back the the tube jig. I attached the aluminum arm things.
I am not liking this jig. It's not the way it's suppose to be. I have a better idea.
As you can see it's off. After you drill all 4 holes doing the same method shown here. If you were to drill a 5th hole,... it should align perfectly with the very first hole. The angle is off by a bit. maybe 43 or 44 degrees instead of 45. Im going to scrap this jig and make the other one.
Time to work on the drill press. I have to reverse it. I was going to initially wire two foot switches but thats going to be a pain in the arse. So Im going to wire one foot swtich and a center off switch too. Going to do both drill presses but im going to start with the smaller one first. I have to get this motor off.
I have to take this thing off.
I have to disconnect this swtich.
Done. This thing is heavy as hell! Cant imagine how heavy the other one is!
This is a capacitor start - induction run motor. It has two windings, the started winding and the running winding. When you flip the swtich, the running winding always has power which means the magnetic fields are always turning. When you flip the switch on the starter winding gets power but when the rotor reaches a certain speed the centrifugal switch turns it off. The starter winding is obviously only for starting the rotation of the rotor. The started winding is power by a capacitor. The started winding is what determines direction. Without it the rotor would not start turning on its own. It needs a push. This is because the running winding creates two magnetic fields moving evenly in opposite directions. Kind of like a game of "Tug of War". Each team perfectly equal in strength pulling on a rope. The start winding is an extra person plaes on only one side of the rope. The extra person enables the one team to pull the rop towards them. Get it? once the rotor starts moving it will become attached to the magnetic field moving in that direction. The other magnetic field wont be able to stop the rotation at that point. It does slow it down a tiny bit but not a lot.
This is the centrifugal swtich or part of it.
When the rotor is spinning fast enough it pulls outward pulling this black disc up towards the rotor.
When its not turning,... the disc moves away from the rotor and pushes down on the actual switch attached to the inside of the rear cover.
This is the rotor.
This is the stator. A bad pic by the way. The cam focused through the stator. DOH!
This is the starter winding attached the the wire from the capacitor. Starter winding from what read is usually only one wire and is usually of a thinner gauge too.
This is the running winding. It usually has two or more wires. The gauge is usually thicker too. Reason being because it's always powered. Wher ethe starter winding only has power momentarily.
Heres all three wires(one starter and two running) all connected the the negative.
Ok,... here's the deal. This is where the process of powering the start winding starts. The white wires is from teh on/off switch. The positive wire. Because the running winding always has power it connected right to this wire. The red wire goes the to the centrifugal switch.
Here's the red wire. Whenteh motor is off,... the centrifuge pushes down on this closing the circuit. Thw power from the res passes through,...
And makes it's way to this white wire that,....
Makes it way up into the capacitor compartment so that it can power the capacitor. From here,...
Another white wire comes down and is attached to the starter winding:) SO I need to switch this starter winding wire with,....
With the starter winding wire attached here. When I do that the rotor should change directions. I want to wire in a triple throw switch. Forward - Off - Reverse. when you want to switch directions you have to let the rotor come to a complete stop. If you dont the rotor will keep spinning in the same direction is was regardless of where the switch is, forward or reverse. Cool beans?!?!
I have to order some switches now. Peace. Oh I made another video. I'm just waiting for REVVER to approve it. I uploaded this video the other day and when I came home it was listed as an error. REVVER sucks.
