Slide rules? LOL! I haven't seen one of those in years .....
Bike builders that have machine tools/shops

Log, log, 12" engineering nerd stick indicator on campus, lol with horn rim glasses! My last rule was imported from China & sold by Layfette Radio, catalog sales. Leather case, plastic over bamboo construction, kind' pricey in those days, post Vietnam 1970 education experience. Money was tight.

KOOL ! FOG, was that will take some time, LOL. Will be worth it when done, you are biting off more then i would chew.
Yes i had mechanical drafting, and architectural drafting, but long ago back in the 50's ............Curt

I have somewhere my Dad's drafting tools, as well as his Beret that he used while enlisted in the Navy WWII. Charts I have for boating, but they are old so changes make them not but probably wall hangings. My Garman 45 GPS I may clean the leaked battery acid off the battery connectors and put new wires in, but it was from the 90's and only used 8 satellites. You may look for apps that allow cell phone to operate navigation without and cell coverage. I had it working marginally, but on the open ocean water it has to be better, no buildings or trees!
MT GPS tech is amazing with the advent of continuous contact & updated real time availability & I too used those 8 satellites in Central and S. America as well as offshore & the waits for repositioning in relation to those eight seemed an eternity at critical times for coordinate updates and global/regional communications, but it beat the alternatives when they worked. When it really matters one needs reliable backup gear and traditional navigation training to find your way. Lost and alone is more than a cliché when it's happening to you, lol.

I was back in the shop for a few minutes to check my machined and tapped bolt circle. It confirms my measurements for the out put drive sprocket of the Sportsman Flyer Reduction System. This is the first one. The 42T receiver sprocket is going to be steel next.
Pat' design and geometry are not in question. I just prefer 4140 PH to 7075 T6.

Hey Rick, I bought a Versalog while I was in electronics tech school in the early 70s and still have it along with the book.
I seen one in a pawn shop back in the early 80s that looked in good shape and went ahead and bought so I still have two
of them. We couldn't get along without one in the electronics courses! They were expensive in those days and at the time
we were living in Phoenix. I went back to the area in the early 80s and the area had really changed. You mentioned
Lafayette Radio and I spent a lot of time shopping in the Phoenix store. I really miss the old Radio Shack and Lafayette
stores.
Allied and Lafayette catalogs were dog eared & worn from my constant reference & wishes searches. Trying to compare apples to apples value and performance wise before spending each dime & yes I too miss the stores....but the catalogs more.

I've owned the Garmin's over the years & confess each died of unknown causes, but just in time to upgrade with a more current model, lol. Mine were used often and in offshore marine environments not friendly to electronics or anything else except to gratify one's soul.
Dying in storage not that uncommon with electronics but that doesn't alter the facts of nuisance & expense, does it?

I remember the old-old-Radio Shack catalogs when I was in eight grade and a freshman in high school. The
catalogs were thick paper back booklets with tons of products from different company's and the only problem
was, I couldn't afford the products. I wish I would have kept the catalogs and at the time I thought they'd be
coming forever. How naive I was at the time! I remember ordering two CB walkie-talkies from the Kleins store
in Chicago. A friend and I got a kick out of using them to see how far we could communicate using them when
our only transportation was single-speed bicycles.
Then, in high school I ordered a Lafayette HE-50b CBtube base radio and used it for awhile. I loaned it to a friend after I could afford a International Executive 50
CB tube base radio so we could communicate since our old telephone lines were not working (pole lines)
before buried phone lines were put in out in the country. Allied Radio also had good catalogs at the time but
all of that has changed now. I forgot to mention, the slide rules were called, "Post Versalogs" which came in
a real nice heavy leather carrying case. Two of my fellow students couldn't afford the Posts and bought the
aluminum ones. After they had taken tests they had to go to the restroom and wash off the aluminum stains
from using them. The Posts always needed talcum powder on them since they were bamboo and would stick
on you at the wrong time taking the tests. You didn't have to worry about batteries going down!
Changing the subject, I found a decent kickstand that works for supporting that bike on Ebay and so far
no problems with it. I can't use a double that is center mounted on this bike like the 49cc bike.

The stock one would have worked if a fella would have heated it with a torch to bend it in to make the bike
sit closer to vertical. The weight of the engine was too much for the welded mount which didn't have any
adjustment and I don't know how it was built inside to repair it since it was welded to the frame.
Hi Rick, mine was a Aldi purchase when a Cub Scout Master assured the Aldi manager they would sell. It was $50. As Patrick McManus said "Never sniff a gift fish" The next one will be that cheap. The one that died, did not fail me when I recorded GPS coordinates of a deceased Badger, and sent to the DNR for their data base.
Jeez! Slide Rules? I started my Tool and Die apprenticeship in 1969. The Summer of Love "if you could get it " My mathematics tests were intentionally long hand. But in 1970 I purchased my first Casio calculator.
Asking price was $100. Pretty stiff on apprentice wages.

I guess a Garmin GPS can be called a tool so they will fit this thread, we have a group of guys that my son and I hunt with every year on Cedar Creek WMA in middle Ga. It's 40k acres so a GPS is a must, we all have the Garmin with walkie talkies function, when each Hunter reaches his stand or blind he keys his device and it sends his coordinance to the group. It's a built in safety feature.
My first calculator after getting out of tech school was a "Texas Instruments Scientific" calculator. I had problems with it a monthJeez! Slide Rules? I started my Tool and Die apprenticeship in 1969. The Summer of Love "if you could get it

after I got it and sent it back for servicing. When I got it back a few weeks later it started acting up again so it went into the
burning pile so back to the Post.
That's handy! I've seen the walkie talkies advertised and wondered about them, good to check out!
Latest progress in upgrading my Sportsman Flyer Reduction Drive and Pat please indulge an Old Fart.
Something to take note of.
Quality steel chain sprockets made by Martin and marketed by Motion Industries are very high quality.
And Motion, is now my go to source these days
My mistake and this is worth noting. I ordered a
13B40 and it was hub'd which I turned off in my Logan.
I then ordered a 35B42 input sprocket and it had a 1/2" wide hub too and welded on.
I am loath to turn that hub off and find the sprocket had potato chipped from released stress.
With a little effort cause I ain't never been here before.
Hubless sprockets are "A"s So an 35A42 is on order.
The photo is the 13B40 drilled and reamed to the hole pattern of the Reduction Drive.

Next comes countersinking for 1/4-28 flathead Torx drive screws. Pat uses 1 /4-28 Low heads which have pretty good grip, but if I recall only have 1/8 Allen Hex drive. The flat heads as we all know hold more firmly the object it is captivating.. Flat heads also because of the greater head contact resist release. I am living empirical evidence of the pain of getting flat heads to release. Today several elements of the weld fixture I have been building (not my design), assembled with 5/16-18 flat heads needs to come apart for modification. Normally it takes a specialty punch to break the friction of a flat head. But all new tooling I didn't want to bugger the screw heads. I didn't Candy Cane the Allen Wrench but that may be because their physical strength is better than twenty years or more ago.
Sorry for the song and dance.
But flat head with torx drive is where I am going.

Hope the full image works for you Steve. No great revelations, but Y'all like pictures as well as I.
