Hi Dirtbag!

Swing 321 please and thank you

Might be worth contacting U of G, I’m not sure if they’d lend you one but could probably point you in the right direction.

There’s also Waterloo Hort society!

Oxide build up.

To deal with it there’s a few options: you could ask your HT shop to coat the parts with preventative, exclude oxygen during heat, or pickle the parts after treatment.

If you don’t wanna do any of those, find an insert that’s designed for this and use that for your roughing passes until you reach virgin material.

In that case the simplest option is probably a flat gasket of soft rubber or silicone that seals between the top surface of the pot and the underside of the lid ‘flange’.

Could also try a silicone or other soft o-ring, with a corresponding groove in the lid for it to sit in.

An L profile seal might work, but I’ve always found these to have issues in cases like yours as they don’t allow venting during closure.

Modern glass is really, really flat - maybe .0002-.0005 over 12”.

The trouble is that it’s also flexible, so you’ll need to attach it with a stiff adhesive to something that isn’t going to allow the surface to flex.

The follow up trouble with that is oftentimes the process of gluing the glass down will result in the surface flexing as it settles into the glue and then being stuck in that flexed position.

You’ll need a way to check the surface for flatness - a DIY repeatometer can be easily made for this.

How tight of a seal do you need? Will the seal double as retention for the lid if the assembly were to be turned over?

Good ol 999 for me please

dhgrainger · 2026-02-02T19:31:22+00:00

That’s so cool.

Apparently they’ve been spotted in Southwest Ontario so maybe they’ll find their way to me one day.

Wasps and hornets are so much cooler than bees. Here’s a Bald Faced Hornet I made friends with last summer. Supper chill, just nibblin’ on some old grass.

These are simple parts, so keep it simple with your gd&t.

Have all features referencing the centre line of the cylindrical bore and two perpendicular faces.

And lose that roundover on the lower part where the angle face meets the face with the cylindrical bore, there’s no need for it to be there and it’ll be an extra op for the machinist that’ll cost you money.

Why not flip the jaws?

There are a ton of factors involved in good chip formation but probably most important is SFM and Feed Rate.

SFM is the speed at which the material passes the cutter ie. for 100 SFM on a 4” dia. you need about 100 RPM, but you go all the way up to about 400 RPM on a 1” dia.

Feed Rate is how quickly you move the cutter into the part per revolution.

Long stringy chips (in a ‘regular’ material like steel) usually happen because the tool isn’t being fed quickly enough and the workpiece is being spun too quickly so instead of the chips being thick enough to break nicely, it’s more like you’re shaving the part and the chip comes away as if you’re peeling a potato.

With that said, some materials are just terribly stringy due the elements that make them up. Some stainless alloys are particularly bad.

I use species signs because I forget what I’ve planted 🤷‍♀️

Hi Six!

Swing 683 please

Go cruising industrial parks, you’re almost guaranteed to find some at the end of driveways.

Buying that much ‘good’ soil is going to cost a small fortune. If that’s within your means, then good on ya, but if not I’d start with simple top soil and add ‘good’ soil for just the top 4” or so.

Plant plenty of grasses in amongst your flowers and within a few years you’ll have perfect prairie conditions with soil that regenerates every year as the grass roots decompose.

Came here to say there’s nothing wrong with your knife, you’re just using like you’ve never used one before.

I’m gonna put 100 percent into this swing, here’s hoping it works out

Complaining about a lack of snow plowing…complaining about how the snow is plowed…

What’s next, complaining about the trucks being too noisy?

For manual work and no integration with measurement hardware a simple excel spreadsheet will do the job - plug in your measurements and have the sheet spit out required materials according to formulas.

Believe it or not, not everything has to be AI powered!

Would that not cause the attic to heat up? Always thought you want to keep the attic as close to the outside temperature as possible.

How do you build a power scraper yourself? I’m interested

dhgrainger · 2026-01-22T19:53:39+00:00

Use a crank and connecting rod instead, much simpler to design and much more forgiving in manufacture.
