Made a start on the jeep spring pivot bolts. I can buy these from RFJP but the postage is high and I would prefer to learn some new skills.

This is a learning project for me, it involves turning, thread cutting, the use of a dividing head and thread tapping for the zerk grease fitting. I chose 4140 chrome moly alloy because it's a strong material, is easy to obtain and is relatively easy to machine in the tempered state .

First step is: turning the stock down to 9/16" ( .5625") and threading the ends to the correct N.F. thread pitch. I prefer the old HSS type single point tools that you grind to shape yourself on a bench grinder . The modern carbide insert tools, well, there are endless types and it is a never ending process finding the correct type to suit .
