UPDATED 11th March 2020: Added straight-through Y pattern, optional flow arrows. Having a european-built caravan in Australia, I found it very difficult to get the 28mm diameter sink and drain pipe plumbing these are fitted with. I tried…
The wonderful EMCO Unimat 3 lathe, for all its extensive set of attachments never had anything resembling a back gear nor did it have the analog of the slow speed pulley bracket available for the earlier Unimat SL. This pulley set is an…
This is my first "thing" uploaded here. It's a replacement clip for a foldable camping table. The table is comprised of a number of aluminium slats held together by elastic, which folds up concertina-style and fits in the carry bag along…
The securing knob on my Ryobi Pro Cut II whipper snipper head literally wore out. This is the head type where short lengths of line are cut and pushed through the side of the head and are held by ratchet cam pawls. This knob works very…
Coming up to the 50th anniversary of the first moon landing, I've been amazed by the efforts of Marc, Mike, Ken and Carl in getting an AGC operational, all made possible by Jimmie saving the AGC way back when. If you haven't seen it,…
TL,DR:* This is purely experimental. Try as I might, I can't get an acceptably fine print from my cheap FDM printer. An SLA (resin) printer should do a lot better but alas, I do not have one. Your own custom font IBM Selectric 'golfball'!…
The C&C 355mm-square (14") mesh grid panels are ideal for small animal enclosures such as guinea pigs, but affixing water bottles and the like to these grids can be a bit awkward if you want something more secure than the usual piece of…
I have a bare 8-slot MDB Systems Qbus backplane which I am building into a rack mounted PDP-11 using a modern server power supply and a discarded rack-mount General Robotics LSI-11 box (which came with no contents except the rusted power…
There are any number of shower hooks on Thingiverse, so why did I create a new one? This design is for shower recesses that are either edge-less glass panels or glass with an extruded aluminium top edge. It's fully customizable. Two nubs…
I installed a mains powerboard in a caravan and had to cut a hole through a vestibule benchtop. The largest (electric drill) hole cutter saw I had was 50mm and was just enough for the power plug to go through, so I needed to have a filler…
A fun little tribute to one of the most popular and influential range of computers in history. Key fob size is 60mm long x 30mm wide x 4mm thick (2-3/8" x 1-1/8" x 5/32"). This thing didn't take long to create. I already had the DXF's…
There have been a few Unimat boring head designs over the years. For instance the Compact Micrometer Boring Head' by GA Harding described in Model Engineer 4th June 1982 and 'A Small Boring Head for the Unimat 3' by BR Davies in Model…
As an option. the venerable Myford ML7 lathe can be fitted with an engineering handwheel on the right-hand end of the leadscrew, a very useful improvement. With the carriage lever engaged, one turn of the leadscrew moves the carriage one…
If you are into vintage computing then you may find this little jig useful. It facilitates the cutting of sharp, straight cuts across 1" wide 8-level ASCII Teletype paper tape. This makes it easier to trim, splice or join sections of…
Here is my attempt at replicating the pushbutton insert for the IBM SYSTEM/360 and System/370 mainframe computers that were popular during the mid-1960s to late 1970s. These machines had operator consoles with numerous switches, lights…
Having recently completed building an ESR Meter (capacitor tester) from a kit (Altronics #K2574 https://www.altronics.com.au/p/k2574-esr-meter-kit ) I wanted the batteries to be accessible from underneath, without having to unscrew the…
This is a much revised version of my Qbus PDP-11/03 LED mount (Thing# 2829191). After opening up the PDP-11/05 console and finding out that it used three 6-LED mounts for the address and data LEDs and one 1-LED mount for the run (btw I…
This is my attempt at the chad collection box for the venerable ASR 33 teletype. I have not printed this (my tty has its original) but there was some discussion on the cctalk and greenkeys lists in the past about making new ones, but to…
This simple clamp allows the Unimat 3 milling column spindle to be locked from rotating, thus allowing the placement of a digital indicator or dial indicator in the Jacobs chuck. Using the leadscrew handwheel, cross slide and vertical…
Here is my replica of the DEC fascia panel clip for the H960 equipment rack, a common 19" rack frame used for their PDP-11 series of minicomputers. To cover empty spaces in the rack there were two panel sizes, 5-14" high and 10-1/2" high.…
I have been modifying modern server rack slides for DEC PDP-11 equipment for some time now, and recently hit a problem when it came to racking up a 3-1/2" (2RU) high PDP-11/03. The computer chassis width only has a clearance of about…
The old DEC VAXstation VSXXX-AA mouse designed by Hawley used a XY tracking arrangement of two roller wheels with their axes canted at about a 10 degree angle, one for vertical and the other for horizontal. This not very popular design…
There are any number of headphone holders here on Thingiverse, and perhaps I didn't look hard enough but I wanted one with a large flat back panel so it could be stuck on with double-sided adhesive tape rather than a clip-on or screw-on…
Having a dozen or so DEC PDP-9 black plastic fascia panels dating from 1968 or so (and no PDP-9 minicomputer to use them on) I designed this clip so they may be used on my DEC H960 PDP-11 racks. This 5-1/4" high (3RU) panel normally…
