Seeking knowledge at the well of Wisdom

I stand behind my numbers. Try it. Move Y .0174" in a cut and verify that .010" has been removed from the face.
The "I edited" (#8 above) post was just to get you to re-read my previous reply (#7 above), in the case you had read #7 immediately after I posted it (before I saw my mistake and edited it).

I have a different solution than @MyLilMule because I answered your question as I understood it (35°). He'll have to speak for himself, or not.

Any further discussion of this is likely to confuse me.

Okay I will try the .0174. After all I am going to be taking .010 at a time 10 times. 5 times per side. The .050 is not critical as I am removing material to be refilled with Moglice. My measurement tells me I have .012 of wear from OEM. Devitt recommends at least a .062 replacement for the Moglice to be successful. I am going to try to document as much of the repair as I can with pictures and or short videos because there is very little information on it on the Internet. My main reason for asking for help is to have a clear understanding of how to determine how much? I have done quite a bit of reading on the subject of triangles and rectangles and most of the information is not user friendly to the end user like me. I had an engineer working for me that would write a book on how to turn on a light switch just so he could show off his Word Porn. . The people trying to run the machines he was writing about had been hanging doors /tires and bumpers on cars and trucks for most of their careers.

In my original post I asked for a simple "Dumbed down math explanation. I like Simple.

Assuming your V way is 90 degrees, the math is simple trigonometry. I'm curious, however, why not use a traditional endmill and nod the head to 45 degrees so you can cut both sides in one setup?

Regardless, assuming the cutting side of the endmill is in plane with the existing side of the V way, you would need to move the saddle .014" to take .010" off the V way surface. For a right triangle at 45 degrees, the length of the hypotenuse can be found by multiplying the length of either leg (they are equal) by the square root of 2 (1.4142...). In your case, one leg is going to be .010", so the hypotenuse is 0.014" - which will be how far to move the saddle. I included a cad drawing that proves the math.

I believe there are plenty of examples of lathe v ways that aren't 90 degrees, so that's a good initial caveat on your part and worth the OP checking.

A few photos of the part and the end mill posed in it would help us nail this...

I will take some pictures of the rough setup and post them today. I was up till 5 am this morning because of the continual storm warnings we were under. It is not unusual for us to be under Tornado watches here in Tornado Alley but actual alerts to take cover will keep you awake. I was here in 1979 when the tornado hit. Google Terrible Tuesday and you will understand why.

Yike! Our hurricanes are slow moving...

Weldingrod1 here are the pictures you requested. The set up on the mill is just the first mockup to make sure it is in the right location on the table. As we all know nothing good happens when you run out of stroke. I've learned a good practice run is priceless before you actually start removing material. The table has plenty of X-axis travel and plenty of Y-axis travel to get the job done but if I put the job on the wrong place on the table you will think I am swatting mosquitoes but in reality, I will be slapping myself all day. The picture of the lathe is the one the saddle will be going on .

Those are sure weird! That straight section next to the V way really complicates things!
Is your cutter long enough for the full width, or are you going to have to trig your way down?
You may need to grind the end flat. The surface speed will go to zero on the point.

I'm in Nebraska, also considered part of Tornado Alley. Just had verification of the fact as a tornado ripped though the area. Made sticks out of some houses, collapsed an industrial building & knocked a train off the tracks. Really dark sky even though it was daytime.

Larry, I hope there was only material damage and no loss of life or serious injury. When I say I was here during the 1979 storm It was Jet Black even though it was daylight when it struck. I will never forget that day. It struck on the southwest side of town and traveled east. It took a path of 3 miles wide and 8 miles long. Total destruction. I will not go into detail here what it looked like, but it was like nothing I had ever saw. 47 lives and hundreds of injuries. My memory wants to describe it here but best thing if someone wants to see is to Google "Terrible Tuesday" Myself after the first day of the media skumbags repeatedly displaying pictures of the devastation it becomes sad to me that everyone including someone with a You Tube channel is trying to make money off of repeatedly displaying the wreckage of the victims' lives. My opinion they belong in the same class as Buzzards. Thanks for your response and may God be with you and those others who were there.
