I was born in NJ, my wife in San Francisco.? I lived in NJ, Florida, and California.? She lived in California and New Mexico.? We had a business in California for 39 years.

After we sold our house in California, the travel restrictions kicked in and we couldn't leave the usa. So, a while in Illinois with friends and then in Alabama with another friend.? We had to leave Illinois, they wouldn't let us renew our California car tag, register it there, or even sell the car to our friends, so we went to Alabama where they didn't care what we did with the car.

Since then due to the SMO we couldn't spend long periods home so we lived in Istanbul Turkiye, Cape Town South Africa, and Yerevan Armenia.? Now after appearing on RT News and a few magazine articles, magic happened and we're legal to stay here.

Tip cutting a long small diameter shaft

 

If ever need to cut a long small diameter shaft. A follower works or a roller box .
Like roller box but do use a follower rest too.?
If point the end of hex or square shafts a box or roller box will work great.
A box type is easy to make in shop too.
?
Here is a roller box?
?
Box Tool can use for watch size shaft in small. This easy way to cut under 1/32" dia?
?
If need to do step shaft in more 4 pcs
You look at this . This box type
