Default Drive Adapters

When I made the last set of gas spuds, I broken 3 of the cheap 1/4” hex x 3/8” square socket drive adapters. Today during a quick job, I needed another drive, to drive a 3/8” socket off of a 3/4” drill chuck, so I needed another adapter. Realizing the problems I had before, I decided to make better adapters.

I used a Harbor Freight 3/8” dr x 6” impact extension, cut it down to the required length, then with the hex 5C collet block, The right sized collet, a 1/2” carbide end mill and about 10 minutes of mill work, I had 2 adapters. I was about to clean up and said, maybe some day I will need a 1/2” version, so another Harbor Freight impact extension (1/2” dr x 6”) gave ups its original form, to aid in the shop work needing to be done.

Not a super hard or technical job, but a good job for a quiet Sunday morning.

Nice idea. Might have to pick up some extensions next time I’m in the store.

Ted,

they are basically to hold the square drive socket that holds the tap, when I power tap on the lathe

Why is it, that I seem to spend about 50% of my shop machining time, making tooling, so I can do the other 50% of the machining??

My short stint as an aircraft machinist included building tooling. I rather enjoyed that part of the job, kind of an engineering/fabrication/machinist gig. When there were actual machinist jobs, modifying jet engine parts for upgrades, the management was happy.

When there wasn't any work, I had to go looking for tooling jobs to keep me busy. That lasted about a month until the engine shop manager stopped me in the hall and asked me why there was ~35 hours a week on his tooling account. When I showed him the tooling I had made for them, he said any further tooling jobs would have to be personally approved by him.

It didn't take a CPA to figure out ~35 hours/week is one too many people on the payroll. Put in my notice and headed back to familiar territory. A week after I left, they laid off 30 people so I would have been one of those.

They have some nice tools and methods for doing things I had never been exposed to. It was time well spent; other than having to work three jobs to pay the bills since they were paying me less than half what I was usually making. A nice little side road tour to recharge the batteries

How did the machining go ?

Did the material act very hard ? or tough but machinable ?
Hard outer shell with a soft nougat center ?

I did the job on the small Rockwell milling machine, used a 1/2” carbide end mill, at about 1200 rpms and hand feed the table, at a table speed based on the sound of the cut. The job went well, the end mill was one I’d been using to open up the CDCO sourced AXA blocks, to accept either 5/8” or 3/4” shank lathe tools, not super sharp, but not dull either. It machined fine.

My friend and mentor, who by the way has almost completely, recovered from his stroke, built a micro-midget back in the day. He used 2-foot Craftsman extensions for his torsion bar suspension. He made them adjustable so that, he could jack the weight of the car.

Every Saturday night, he would wipe the track with the competition. I was a push-car driver there for a number of years.
