Lathe Hack and old school tool use. - Page 8

Let me see, cat vs coyote, I bet the coyote had a tasty if a bit furry meal.

I can see that cat now, whiskers twitching, thinking "I got my teeth in it, did I bite off more than I can chew?"

The table of the tablesaw is now clean and has a coat of car polish to prevent re-rusting just in case moisture gets too high. I have to clean out the grooves for the miter which will take a piece of fine sand paper and a small wire brush. Next order of business is to clean the trunions, carriage, and arbor. The bearings are in excellent shape, much better than my old saw. I decided to do something about that so I ordered a pair of new bearings which will be put on the old tablesaw tomorrow.

As for worth with his bee powered flying wood lathe, I suspect he will give up on the idea of putting bees in those boxes in a hurry. In fact, a couple of drawers would make them into excellent storage space for lathe tools. If he puts 4 wheels under them, the lathe will be portable.

I used to dread mowing the lawn around the bee hives.
Make sure you buy bearings from the US or Japan NOT China.
Get the number on the bearing or size then go on line and order them.
There are several good suppliers.

Never mind you already ordered them.

The reason I brought it up was I read on line and saw a video about the NEW south bend lathes or at least one they discontinued.
But with everything you have to take it with a grain of salt.
The bearing was out on one that was practically new and it was made in China.
It was given to a guy.
Well did it run low on oil did someone run it without oil wrong oil who knows.
The other was a new one just like it the cross slide bolt stripped out.
Did he over tighten it, more than likely as this was a guy that knew nothing about lathes.
My new late drips a wee bit of oil out the head stock at the spindle bearing it is supposed to.
It means the bearing is getting oiled.
Another thing that bugs me is to see people on line see how deep and how fast of a cut they can make.
Why do this it is stupid.
I'm talking about frigging 1/4 inch at a time.

As best I can tell, one coyote set up in the niche behind the cat door and the other enticed Hoover out. Quick chomp on the neck and off into the woods.

Earlier they got two of my small boys. McKinley never came home. Colin made it back through the cat door with deep tooth marks, but dislocated a hip and had to be put down.

If I was half a hunter there would be dead coyotes in Georgia.

Our farm cats and coyotes seem to have a live and let live agreement, they can be hunting in the same field knowing the other is there and no problems.

Speaking of coyotes I spent least night figuring out a way to make my own falling block 22 Hornet rifle from scratch.

Made this male 1/4 20 TPI to Female 1/4 28 TPI adapter today for my dial indicator.
The wrench shoulders were done with a file.
Fits a 10 MM wrench.

Dropping a link here for gears and another link for calculator.
All this time I have been trying to figure something out and it was right in front of me all the time.

When I went from trying to find the pitch of my gears nothing ever came out right with an on line calculator or me doing it at home with a formula.
That is because I was trying to find American diametrical pitch.
When I went to metric module pitch everything fell into place.

Sometimes I make comments here for myself because I cant remember what I found or discovered.
This has been a long hard trip for me because I dont have a teacher and have to teach myself.
One of the problems is the metric and imperil charts and how things are done.
The other is people not using lead and pitch correctly.
Out of all the looking I found one gear site that sells gears that explains things.

The confounded DP imperial chart makes me have to do a bunch a math to figure out what the pitch or lead is on a worm shaft.
I need to start writing these formulas down before I forget them as I still cant find my books.

But the good news is after I found what I needed I was able to convert things to thread pitch on the lathe.
Then I looked at the charts the one engineer put up in one of the links at the beginning of the thread and found every one of them or something so close it didn't matter.

Here is what I have done.
On the lathe I have taken the middle idler gear and flipped it around so now it runs off the 91 tooth gear instead of the 86 tooth gear.

This allows me to be able to flip the bottom gear G from one gear to the other.
If I keep it running on the 91 tooth gear everything stays the same.
If I flip it around so it runs off the 86 tooth gear and F gear the top gear stays on the 91 I get more ratios.
By keeping the F top gear running this way or swapping out the F change gears, flipping the G bottom gear or changing it to the 60 tooth I have close to 690 different gear ratios I can run on the lathe.
Now here is what baffles me.
On the gear chart when running imperil threads it shows the F gear and the G gear running off the 86 tooth idler gear.
Why did they do this?
The middle idler gears do not change the ratio between the driving and driven gear no matter how many or what size as long as they are all in line.
As strange as that may seem.
Or at least what I have read I know the three gear set does it.

Saw blade lathe hack.
A rusty 100 tooth saw blade I found in the junk pile.
I dont throw much away I can make use of and this is an example.
I said this on another thread but here is is again.
If you have a lead screw with 10 treads per inch and you rotate it one time it is going to move 0.100 or 1/10th of an inch.
If you divide 100 by 1 you get one or in other words the screw will move 0.001 or one thousands of an inch.
So here is what I did, I made an arbor for the saw blade to fit on and put it in the spider on the back of the lathe with a stop pawl so it will stop on every tooth.
I then set the cutting tool up on the lathe to cut at a 90 and set the depth and locked the carriage down.
I then ran the top slide to the stops and did this 100 times rotating the blade one notch one tooth at a time.
Then I set it up to cut a longer line and cut ten lines like this.
Next I counted five from the last long line and cut one and then just counted to ten after that until I made a complete rotation.
Now I have sort lines representing 0.001 ten lines representing 0.010 and ten lines representing 0.005.
I have two of these to make for some big dials I am making.

Tried that link and the program didn't do me any good because I am too stupid to open it and run it.

Trying to ween myself from the easy way and re-learn math formulas for doing it by hand.

Right now I am trying to figure out a way to connect my rotary table to my lathe so I can use it to cut 360 lines in a disk to put in place of the graduations that are there.
The lines need to be about 1MM apart.

Worth1 · September 25, 2016

Well that was easy enough I already had the part made just so happens one of my spare cylinders I made only needed a few thousandths turned off of it.
It has zero clearance.
All I need to do now is support it to the lathe nice and solid.

If anyone is wondering about safety the lathe is unplugged and everything is in neutral.

Nothing if the pawl was up.
The big rotary table I dont even want to think about.

Even with the power on there would have to be several things to happen.
The power button would have to be turned on by twisting it.
The power start button would have to be pushed to energize the machine and the forward and reveres lever would have to be engaged.
I took the extra precaution of pulling the plug.
When I had the saw blade on it I did have it in low gear and turned the motor by hand to make the blade move.
