Section drilling - with one bit and No measuring

[PatrickR]

@rherrell made me two step bits. One each for Bock #6 and #5. I have not tried the #5 yet but will soon and report back here.
This worked perfectly. One hole to drill with no measuring, for what used to take 3 different bits with one having a fairly tight tolerance for depth. Simply drill through the blank and stop when the largest portion of the bit goes deep enough to burry the housing flange. Then run the tap all the way through. Sooooo much faster. Thanks to Rick for the usual high quality work and attention to detail! Shown here on a Beaufort mandrel.

I made some measurement errors on the #5 and had Rick make me a corrected #5 bit.
works great! The #5 requires an additional drilling to make clearance for the converter. 2 bits to do what did take 4.

Need to get him measurements for the Jowo sections now…

Great investment!

I plan on getting ones for jowo but not until I have made the mandrels. It will be awhile.

I did a time study.
Going from raw rod to ready to turn and shape on a mandrel = 13 min. This was working at my normal speed, getting and replacing tools etc. I didn't do anything to artificially lower the time. Doing them in batches would definitely reduce the time spent for each.
Ive never kept track of the time it took using multiple bits.
