Not An Engineer

State of the Workshop - April 2024

New toys and next steps.

It's no state of the workshop, but it's something!

I finally sat down to record an update on the weekend, but once I sate down to edit I realised I didn't have anything super exciting to talk about, because I was still in that inbetween; catchi...

We're still moving

Hey everyone, and welcome to all of you who've joined since the last video!

Apologies for the radio silence, have been scrambling to get things organised after being down that cyclo-rabbit-h...

I made a precision gearbox - with NO GEARS

This was one heck of a project, but I made it in the end. A (nearly) zero-backlash 4th axis for my home made milling machine.

A stitch in time

This photo does a great job of portraying the state of my brain after a week straight of editing. But it's so close; and I was right about the length, at 29 minutes, this one is more of a saga. Wi...

Get back in the booth!

It's finally done. What an undertaking; this project has really pushed the limits of my capabilities, and absolutely given the new machines in the shop a run for their money. Is there a machinists ...

It was back to the drawing board

I got right to the end of that first iteration of the cycloidal drive, only to realise it had some pretty critical design flaws, and it's form factor wasn't going to be very useful. Luckily things ...

State of the Workshop - March 2024

Today we're talkin' cycloids, change gears, and quick change tool posts.

Something came up...

Believe me when I say I had every intention of shooting the next workshop update video today. But when a listing for several thousand bolts pops up on marketplace for $300 (AUD), it's kind of a dro...

My god this thing is satisfying.

Got the two cycloidal disk's made yesterday. They're almost useable; but I've got a bit of tuning to do.

With both disk's installed on the camshaft in the housing, there's a bit of binding....

New beginnings

Hey everyone, and welcome to those of you who've joined over the past couple of days!

My housemate has just about finished moving out, and the shop is in an absolute state at the moment, so...

I've reached a TURNING point

Spin me up scotty, we're off to round town.

Back on the tools (for a moment)

Almost finished editing the lathe video, just waiting on the final say on the sponsored segment, and to add the animations, so while I wait to hear back, I thought I'd get a head start on that cycl...

End of an era

Picked up this beautiful old drill press on Friday (the pillar is actually solid round bar) from probably the last (at least that I know of) precision engineering workshop here in Marrickville.
...

State of the Workshop, February 2024 - Now in 4K!

Hey guys, here's where we're at: I got a haircut, we've got a new lathe, we're making progress on the tripteron and the cycloidal drive, the workshop is DOUBLING in size, and I'm dipping my toes in...

The World of CADmin.

Hey everyone! Definitely time for an update, so here's some snaps of what I've been working on. Unfortunately I've mostly been stuck on the computer, researching and planning for the next couple of...

State of the Workshop, Jan 2024

Happy New Year! (If you're not in Australia, this message will be arriving from the future) Here's to a whole 'nother year of just makin' stuff. Thanks to all of you for being here, I've really enj...

I need a straightedge, so I made three.

Have you seen the price of precision metrology equipment lately? Neither have I, I've been too busy rubbing these sticks together (And trying to animate the explanation of why).

Thanks for th...

Cross-roads

I've been rubbing these things for days now, and I'm finding that when working with such teeny tiny numbers, it's easy to lose perspective/develop a certain level of insanity.

So I put it to...

State of the Workshop - December 2023

Chattin' about straight edges, prop making, and some new gear in the workshop.

This is my life now + Q&A Announcement

I didn't believe all the stories about how time consuming scraping and lapping three reference surfaces together would take, but now I know. It doesn't help that I ran out of coarse diamond paste p...

Heard you guys like surface finish

Have been getting by with a HSS bit for the fly cutter for ages, but enough was enough. Knocked up a quick and dirty carbide insert holder today, and by Jove, I'm blown away.

Plus now I can...

Machine go brrrr

The trouble with the Whitworth three plates method is, obviously, you need three plates. While it does mean I'll eventually (hopefully) end up with three beautiful reference surfaces, for now it me...

Side projects on side projects.

Alongside working on the straight-edges, I've been putting together this I'd lapping arbour. The lap itself is based on robrenz's design; its expanded by a taper inside, and locked rotationally by ...

Improvise, adapt, overcome.

When the only car you've got access to is a zippy little hatchback, and the steel shop wants $3.90 a cut, you've got to think outside the box. I picked up the material and started making chips for ...

3D Printable Tool Racks

Hey everyone! Thanks heaps to all of you who've come aboard, I'm excited about the possibilities your support will enable. Here's a little bonus for anyone with a 3D printer and a milling machine o...

State of the Workshop - November 2023

Basically how I've learned CNC machining

Made a dangerous mistake while working on this part - okay, maybe more than just one ("When is this guy going to make some proper hold-down clamps?").

But the way I see it, if you're not havi...

Yeah, that's not going to work...

It's easy to get carried away with designing a project, and while I was definitely accounting for SOME tooling side quests (Stay tuned for those!), this one got me totally by surprise.

I also...
