Since I already had metal chips and shavings all over the lathe and mill I thought I'd knock out another small project on my want list.
When I use my rotary table on the mill, I usually remove the vise so I have some made up T-bolts that I made eight years ago when I purchased the mill. However, during a recent smaller project I didn't need to remove the vise and therefore I thought I'd make up another pair of T-bolts.
I grabbed a 5" length of 1" stock from my drop drawer and began taking it down to size.
After getting the two major dimensions to size I began cutting the steps for the T-nuts. I plunged them as I moved along the length of the bar by staying .010" from my final dimensions in both axis to allow for a clean up pass to bring me to the final dimensions.
T-bar stock ready to cut off a couple of 1.1" lengths for the T-nuts.
Cut the heads off a couple of 1/2" grade 8 bolts then thought I'd practice some single point threading on the other end. I needed 1/2"-13 threads.
Threads done.
Nut fits on nicely.
Parts ready for drilling and tapping of the T-nuts.
Setup the two T-nuts in the mill vise. The left T-nut is up against the work stop.
Once one is drilled and chamfered, I swapped them around to do the other rather than re-index on the next part. Using a work stop makes for quick component swaps when repeating processes.
Parts cleaned and ready for the final step, welding.
