i got a cased set of 3/4" drive sockets very cheap at Harbor Freight a few years ago.
the reason they were cheap is that the 18" breaker bar was broken
i just used an adapter and used a 1/2" breaker bar as a go around for a long time.
this time my 1/2" breaker bars were too long, 1/2" ratchet didn't have enough leverage, and my wrenches were too small for a 1-7/8"nut.
i have the socket in 3/4" drive and need to tighten 3 nuts......
Sure i could buy a new breaker bar.
i coulda welded one together from 3/4" stock, but that's waaaaay too easy
i decided to do the next more difficult thing, repair the old piece of crud.
i extracted the cross pin and removed the drive end.
here is the break
as a temporary measure to restore use of the breaker bar, i decided to make a new drive head from scrap 7075
and put humpty dumpty back together once more.
it wasn't difficult,
i had some scrap knurled roller sections of 38mm 7075, begging to be repurposed
here is the chance to shine (until a steel replica is made )
cut off the broken side of the breaker bar and turned a 21mm OD to a length of 2"
i mounted the 38mm section and parted to length of 4"
i bored the section to 20.9mm ID to 2" deep
i mounted the section in the Bridgeport vise and milled the fork end of the section to depth and width
i press fit the handle into the section
i remounted the assembly into the Bridgeport vise and drilled for a crosspin for the retention of the head,
as well drill the bore for the retention for the articulating square drive end.
i counter bored said bores
i pushed a 3/16" roll pin in to retain the head
i re-used the OEM pin to retain the drive end and peened the ends of the pins
here are some pics
i'll be making a permanent replacement, but this show went on
i was able to continue the job
thanks for reading!
