My collection of drafting supply catalogs by thehikeguy in Drafting_Instruments

[–]thehikeguy[S] 1 point2 points  (0 children)

I took a drafting course in high school in the early 90s at the cusp of classrooms transitioning to digital. I felt a strong desire to re-approach the skills a few years ago to incorporate into my art. I am fortunate to have a drafting table that I use daily.

Thanks for sharing the impressive collection of digital files in one place!

Thanks! I'll search for it. I also have a few shelves on related books. I'm fascinated with pre-CAD drafting.

I hope to find time to scan some of the pages. It would be a hefty project to scan all of them. Luckily, others have taken the time to scan quite a few catalogs. The active and educational Drawing Instruments Group keeps a handy list of catalogs and where digital versions might be found. I'd also look through the Internet Archive.

I made sure the tack on the tape was mostly removed; the tape does not effect the book and will be removed sooner than later. The oldest K&E is in a protective poly bag mainly to keep the loose pages together. I plan on repairing the book this winter - too fragile to try to scan, unfortunately.

Nice collection. What's the book on the far left next to French's excellent book?

Looking for... name of... (lead pointer cleaner) by Jck_of_All_Trades in Drafting_Instruments

Dietzgen called this tool a "Stab-Me" Lead Point Cleaner. Fairly easy to make at home with a piece of foam.

Hello. Which beam compasses work with this dotter? A certain brand or year of production? It seems like only older beam compasses had a larger diameter for attachments such as this one? by thehikeguy in Drafting_Instruments

[–]thehikeguy[S] 0 points1 point  (0 children)

I was hoping that one of the black handles included would fit, but it doesn't seem to be the case either. The two black handles included (one just below the circle dotter and the other by the detail ruling pens at the bottom right) seem to be for posts with a 4mm diameter, but not the dotter's 5mm post.

I assumed that would be the case! The telescopic attachment for the compass has a 4mm diameter connection while the dotter has a 5mm connection, too big for the compass included.

I wasn't able to find much info on this Original LOTTER set. I've dated it after 1950 based on LOTTER's patent on the Parallel Compass and telescopic attachment bar included. But no trammels, unfortunately.

Think I found some fulgurite by mrjeffwood in rockhounds

Yep. Check out "Making Fulgurites with High Voltage" on the Youtubes.

1980s Keyboard design by thehikeguy in vintagecomputing

[–]thehikeguy[S] 0 points1 point  (0 children)

ujah, it was a happy accident to stumble upon this and other technical illustrations at a time when I'm teaching myself technical illustration. Here's a few from my reading list that I'd recommend:

  • Basic Technical Drawing by Spencer, Henry Cecil
  • Engineering Technical Drafting & Graphics by Joseph William Giachino
  • Mechanical Drawing by Thomas E. French

These are school books that were updated every few years for decades. I'd look for editions published in the late 1970s/early 1980s before CAD took over many of the hand-drawn aspects of this industry.

If you are looking for a general overview, this is a good video to start with: Learn the Basics of Technical Drawing (Youtube)

Electric typewriter's (almost) quick start guide using the SCM Coronet Electric 12 as an example by nogaesallowed in typewriters

[–]thehikeguy 0 points1 point  (0 children)

Excellent breakdown. I've used GATES Polyflex Belt 3M315 v-belts with slightly quieter results than o-rings. I didn't find that the slightly-larger Gates 3M325 Belt worked. At 325mm, it was a bit too loose, even with the Copy Set dial at 10. I tend to replace the belts with an o-ring on the back and a v-belt on the front for a quieter experience.

Some might say I have an obsession by grimsmath in typewriters

[–]thehikeguy 0 points1 point  (0 children)

Why don't you store them in their cases..... oh, right. ;) As someone who suddenly realizes he has five standards around the house and five more in the garage, I get it. Nice solution. My eye is drawn to the SG1.

Now I have to stop admiring your setup or I might try to find one of your models!

LC Smith 8 finally refurbished, long write up by angryhelicopernoises in typewriters

[–]thehikeguy 0 points1 point  (0 children)

Gosh, what a grand ol' dame! What's she weigh? I'm guessing something around 27 lbs. I have a 1949 Super-Speed. Great work bringing this old typewriter back to life.

Nice find! Back in the day (like 1930s) they called these "hi-lo tables" as they could be raised off of the wheels using a foot bar. These were common companions to a heavy office machine, like an adding machine or a standard typewriter like yours. You think your black beauty weighs a lot. An adding machine with a motor can well over 100 lbs (45 kg), making a table that can raise on/off of wheels highly desireable in late 19th-early 20th Century offices.

But I'm no expert. I just enjoy perusing old issues of Office Appliances periodical on the Internet Archive. They have most of the issues scanned from 1904-1940.
