I whipped out another half nut from one inch PVC for testing because the other one was from a fitting.
I decided to use this because one of them needs to wear more than the other. Far better it be the half nut than the lead screw that takes forever to make. I aslo experimented indexing with the lathe spider and a cutting tool turned sideways. I made a simple stop out of a 2X4 so each line would be the same. I put 4 exactly spaced lines in the bar end just to see how it would turn out. The line you see is the first line cut and re cut after all lines were cut to prove they are evenly spaced. These lines more than likely won't be used later. Worth IMG_20160626_3511.jpg IMG_20160626_26748.jpg IMG_20160626_43510.jpg |

Here is a project in between projects that is completed.
Yesterday it was 6 threads per inch, today is was 48 threads per inch. My Leupold sun shade wouldn't go on due to the rear site so I made a custom one that would. No it it not a trick or a fake it really does screw in and out with a nice snug fit. Worth IMG_20160628_44126.jpg IMG_20160628_59508.jpg IMG_20160628_813.jpg |

Now that is painted and ready to go into action it is absolutely worthless.
The pellet rifle is a brake barrel and it wont open up with the sun shade on. I knew this some time ago and forgot about it until I put it on and looked at it. It does look nice though. Worth IMG_20160628_31694.jpg Last edited by Worth1; June 28, 2016 at 02:20 PM. |

Speaking of pellet rifles and the dear ahem animals to which they might apply, I saw this story this morning of moose motorcycle encounter and had to share it. My browser wouldn't show me the video so I hope it works in yours - cycle dashcam of moose dodging... lucky rider!

When I see the deer in the garden I shoot a sheet of tin hanging from a tree next to it. The pellet whizzing by their head scares the devil out of them too. The more I think about people hunting with them the more cruel I feel it is. Worth |

Now for the treads and why I am showing pictures of them.
For some people their goals in life are different. Some want to sky dive or climb a mountain. Others want to go on an ocean voyage. For me ever since I was a little kid I wanted to be able to do stuff like this. I simply cannot express the excitement I have cutting these tiny little threads and having them match something someone else has made. Each thread is 0.02083 apart or the thickness of two razor blades. When I was little I would spend hours reading how to run and this stuff. When I got older I would spend hours reading the same thing. It is how I entertain myself as opposed to watching sports. The big cabinet I have in the garage I made and when it was finished my wife heard me cussing. What is it now, what is wrong? The darn cabinet came out 1/32th of an inch bigger than I planned. You have got to be kidding me she exclaimed. To ramble on some more here is a tail of how 1/32th of an inch can matter in wood working. When I worked running molding I ran everything down to plus or minus a thousands of and inch or so, yes you can do this as crazy as it may seem. Well the guy making face frames picked up some old material that was made in another shop before we got our molder. He used a wooden block as a spacer to space the face frames for a drawer bank and sent it off to have it put on by someone building cabinets. Then it got to the guy making and putting in the drawers. The top drawer wouldn't fit in any of them. There were 8 drawers which would make 7 of these over sized parts of the face frame. 7/32 is 1/32 under 1/4th of an inch so the gap was too small for the drawer to fit in. The kid didn't understand how this could be so I had to explain to him how inaccuracies can accumulate in to bigger inaccuracies. This is the reason for all of the crazy contraptions I am making. It really does matter on measurements even with wood working including framing houses and pouring foundations. You start with a small mistake and it turns into a nightmare the farther along you get. Some people get it and some people never will. Worth |

Here I am going to show a way to use the height gauge, a combination square with center head and a flat surface to get the center of a circle.
I need to drill four holes evenly spaced dead center of the slots already in this four jaw chuck. They need to be flush or just below the surface of the chuck so I will have to do what they call counter drill the holes. I have already measured that and I have plenty of metal left over to do it. I need to do this so I can mount it to the rotary table. The height gauge has a carbide scribe on the end to etch little lines as you move it across the surface. You run the gauge down to the flat surface and zero it. You then measure the height of the object this being the chuck. This was 6.294. You dived 6.294 by 2 and get 3.147. You set the compound square up on the slots like you see in the pictuer. This sets the chuck where you want it to make the marks at 3.147 exactly in between the slots already there 90 degrees apart. I could have just used the center head but this was more fun and accurate. IMG_20160629_34372.jpg Worth Last edited by Worth1; June 29, 2016 at 04:29 PM. |

Here is the next installment after the lines are marked I need to be able to center the chuck on the rotary table to do this I had to clean and true up the center hole of the chuck.
The rotary table has a true hole to do this but I am going to have to make a tapered pin that fits in it and the hole and in the chuck. This way when I turn the table it will be concentric and I can use the 4 jaws on the chuck to make things eccentric if I want. The applications for this device are endless. Everything from cutting gear teeth, drilling evenly spaced holes, cutting groves for O rings, spokes for a hub and what I intend to do is make another indexing plate I can mount to the lathe to make dials to make an X Y table for the drill press. You can even use it to cut flutes in something or make other tooling.

With your understanding of precision/accuracy while working with metal, wood, plastic,...
I am very surprised at the fact of you being not so precise while adding tomato food to your plants and pushing their limits. Just kidding. How is Fred doing?

Worth, I think you have genius in there. I truly think you have to have a precise mind to understand it all.

Nothing like making stuff. As a kid made an ice boat with lawnmower engine and hand carved propeller. Also made a mortorcycle from a bicycle and a lawn boy engine. More model planes than I can count, Made my own fireworks, real stuff with colors and such. Model hot air baloons, Got bored.with rockets and made my own rocket engines, used to be able to get saltpeter at the drugstore. Carbon arc lamp in the basement, that was a mess, somehow didnt electrocute myself or go blind. A small blast furnace to make steel, well tried anyway. Always making something. Didnt matter that steel was free I just wanted to try and make some. That was all as a kid. Been making stuff since I can remember, when I'm not making it I'm thinking about it. Mrs N just shakes her head. Now I make hydroponic stuff, lasers and maple equipment. Seems like I do stuff for a.reason now, back then I did it just because. |

This is all the stuff they taught folks in school but didn't apply it to anything so it was worthless education for most folks. I had to turn around and teach myself out of desperation. Here is the project just about completed at least so much as I can show what this thing does in action. I still need to get some longer machine screws but it does work.'Also the factory dimple in the thing is right where I need to drill the fourth hole. Now that I can mount it I will have no problem fixing that. You will also see the taper pin I had to made and I still need to get to the part the goes in the chuck. I just had it this morning and I cant seem to find it now. There sill needs to be clamps made and some more stuff but here it is. What I have done is drilled 8 equally spaced holes in the pipe. When I got to the first hole the bit went right in again. There are also dividing plates for this thing so I can index all sorts of combinations with it. Here is what I did I divided 360 into 8 that gives 45. Now all you have to do is drill a hole on zero go to 45 and drill another. Then it is 90, 135, 180, 225, 270, 315, rotate it another 45 degrees and you are back to zero a full 360 degrees. 360 divided by 5 is 72 so you would do the same thing. Anything that goes into 360 evenly is easy but you can still do others this way too. Worth |

Nematode I see a pasta drying rack in tbe future and many more things.
There has been a super duper garlic press in the back of mind for years. One that really works. That is not walnut oil it is a walnut oil can. Then I remembered you dont need to oil cast iron when you drill it. Worth Here the critter is in action.

Here is what 1 degree 25 minutes and 50 seconds look like on the lathe compound protractor.
I have fooled with this thing for some time now to get it this way by using a MT 2 taper and a dial indicator to prove it. I would say the protractor is pretty darn close as this angle is really close to 1 1/2 degrees. Worth IMG_20160701_43984.jpg |
