3 Wire thread measurement
#11
Didn't Tom already do a video showing how to use thread wires? 17428
My memory isn't so good anymore so maybe I saw it somewhere else.

I did use the three wire system in my video on cutting external threads, but I didn't do one specifically on the three wire system.

I'll add it to the list.

Good, my memory isn't quite as bad as I thought. Smiley-dancenana

I use wires all the time. If im on a shaft above an inch or so, I use rubber bands or o rings to hold the wires in place while i measure over them. On something small i usally use a piece of dum dum and stick the wires into it so i only have to hold the one end and dont drop the wires. I have used wires to measure double lead threads also.

Welcome aboard eightball. I've used rubber bands in the past, but normally end up launching the wires across the room with them. It's probably just my clutziness. Big Grin

Thanks Tom, I hope you saw on one of the other forums that I am now cancer free. A colostimy is a small price to pay to see my granddaughter grow up. I posted once b4 a test shaft i made to make a #4 double lead left hand acme nut. Being a 1/2 inch lead i had to be very creative on how i held my wires. If i dropped them they went into the river. This was an automatic discharge valve that is literally over the edge of a river. I used o rings on the wires and a couple of rubber bands to hold a 1/4 tool steel over the top two wires to span the gap so i could mic over the wires.Fortunantly both threads were the same pitch diameter. I made the test piece about a thou bigger than the actual valve stem. the nut fit like a glove. I have made several ends for hydraulic cylinders at work measuring over wires held on by o rings. The other machinist at work borrow my test plugs all the time. Kinda funny when they used to laugh at me for making myself additional work. Guess i get the last laugh huh?

I sorta thought we might have had something in common, I had a prostatectomy and subsequent radiation 12 or so years ago.
We just gotta hang in!

I was actually banned from that forum (along with most everyone here) for promoting my instructional videos, so I didn't get the news. Congratulations on beating the odds, it must feel good to have a new lease on life.

Hate to here that Tom, I like your no nonsence approach to machining. Kind of ironic, i found this site watching a Doubleboost video on the other forum. To tell ya the truth its not as active there as it once was.Glad i found my way here.

Steve, I had rectal cancer. Went through radiation and kemo 5 days a week for a month to try and shrink the tumor. Fortunantly it never got in my lymph nodes and all my margins were clear. I have a permanant colostimy, but by god I have A future now. I dont mean to hijack the thread , im just new here. Try to post a pic of my method of measuring over wires but couldnt get it to work. Not sure what im doing wrong.
