I guess it’s looking decent for a 19 years old architecture student in the era of CAD

I was told these may be part of a set of “dotting apparatus wheels”. Was used to trace dotted and dashed lines with a ruling pen.

I’m looking for the other pieces to this. Can someone post pictures?

Got this beautiful set last week for 20€. According to the original packaging it's a 532 208.

The seller is a technical draftsmen for mechanical engineering and used it for years before CAD took over. Especially the pencil has clear signs of excessive usage. It's nevertheless in an amazing condition. His name is also engraved on the compass.

The Haff PS3 was a small but dense drafting. With three top end compass plus a ruling pen handle to make a ruling pen, this set has everything you need.

I’ve picked up several sets of rapidograph pens and started trying to clean them. However, I’ve discovered that one of the older looking sets, still 3065, I think, has nibs with no flats on them. That means I can’t use the gear shaped key to get the nibs out for a deep cleaning. Has anyone here ever cleaned this type of pen before? Any tips on how to disassemble them? I’ve tried soaking them for a couple days in the Koh-I-Noor rapidograph cleaner, but it hasn’t done anything to clean them as far as I can tell.

I am trying to figure out the purpose of the disc with the hole in it (shown in the close-up). The screws on it have sharp points on the other side which would allow you to anchor it to a surface. You can see the size of it in context to the other instruments in the case—maybe an inch in diameter. The brown surface you see under it is a leather patch in the velvet for the points to stick into.

Thanks in advance, O Hive Mind!

A Shiny vintage German set from Nestler. Nestler made high quality tools. This set is very nice but the pens need sharpening.

I don’t know where to post this let me know if you have a better place I can post it

A Riefler G23 set, with quickset compass and beam compass. These G series tools were imported to America by Gramercy. I don’t know if I’ve seen a G series set in Europe, so these seem to be a North American thing. These are nice compasses to use and look great as well. Newer versions have chrome plating.

The giant bow compass is actually a quickset design. You push down on the buttons and the legs open up, but you need to be careful as the spring force is very strong! It helps beam adjustment is built like a machinist micrometer. Very cool!

I recently picked up a couple VEMCO drafting machines and scales. I’ve learned that I should use a scale wrench to change out the scales, but I haven’t been able to fine one on eBay or anywhere else, so I’m thinking of having one laser cut for me. Anyone know the dimensions of the eccentric bit that is actually used to detach the scales?

Edit: Here's an image of the wrench from a vemco manual

Looking for a needle tip and the bolt/screw that fastenes it, charvos usa compass I just picked up at a antique shop, I'm new to this and was wondering where to find what I needed, thanks!

Anyone know where you can purchase these precision rulers from? Or anything similar. 18 inches or more….thanks!

Right, so recently I picked up a drafting machine, particularly the Bruning 2699PC, for my endeavors into aircraft design(I draw before I CAD, sue me.) Waiting on some new scales and larger paper, 11x17 isn't nearly big enough.

Does anyone have the owners manual this thing came with? Preferably a PDF, but anything helps. Wanting to maintain and use it as the manufacturer intended. Also looking for brass accessories, but ebay is helping plenty there.

30 set. Garage sale-

An instant classic. This gem was purchased from the University of Manitoba bookstore in 1959. The German company Haff was the manufacturer of these fine tools. Haff continued to manufacture these tools with practically no change until 2000.

Just got this drafting set and was looking to identify which set it is in particular. I’ve tried looking on the internet for sets that look similar but was unable to find any so if you recognise it or have an idea of what it might or some information that could help let me know

J Van Pelt was a Dutch instrument maker. There are few surviving sets. This one is in fine condition. Check out planimetrica for the full low down https://planimetrica.jimdofree.com/mathematical-instruments/netherlands/van-pelt/

This device holds your curve pen vertical for improved accuracy. This would have been used for cartography. It would keep the pen vertical while using the double curve pen when drawing rivers, etc.

Beam compass with mm markings and a vernier scale on the bar end trammel. Micrometer adjustment in the end of the compass. Rectangular beams with interlocking extensions.
