Project Logs / Summer of swerve
« Last post by WeldingRod on Today at 03:02:15 PM »
Just so there are project posts ;-)

I've been working with my First Robotics kids a lot...  basically ran the program out of my garage during Covid.
This summer they wanted to try swerve drive.   After seeing a bunch of top teams running them, I bought in.  We reviewed a bunch of designs and settled on Nick Coussens' "2021 Winter Swerve" design, the end results of about a decade of improvement.
I had to -really- up my game on 3d printing and cnc routing to get bearing class fits right off the machines.
The black parts are carbon fiber filled ABS.  Lots of learning there too...
3d printed 3mm pitch belt pulleys!

One thing that comes out of these rather excellent threads is that I find out about things I never knew I needed - I've had one of those rain gauges since you mentioned it, alongside my existing 'weather station' on my bedside table.

Now I don't even need to get out of bed to see if it is raining or not :-)

Good news, Andrew. I think that you now can be fairly certain that the foundry is water tight, to all but downpours of biblical proportions, that is  :clap:

Oh dear, do you need to borrow a dehumidifier to stop the rust? I have a decently large 'contractor' one.

Thanks for the offer, but I have a small domestic one, and that seems to have worked wonders overnight. A couple more days and I'll be happy that it's all dried out. Maybe there'll be a little moisture left in the lagging, but that can sort itself out over time.

Strange. If you email them to me Iíll see if I can upload them to the thread.

I am not sure what is happening but when I try to load pictures I get an error code "HTTP error 500"

You may recall the problems that I had with the roof of my foundry - lots of leaks, lots of repair attempts etc, it ground on like a cracked record.


Well today we had an absolute deluge in a short space of time. My rain gauge has recorded 43.4 mm in the last 24 hours but a lot of that happened in about 20 minutes.

Hearing how poor old Graham (Seadog) has suffered with his workshop roof leaking badly I thought I'd better go out and see how the foundry was fairing.

Delighted to say just a minor (tolerable) damp patch in one corner, so it looks like the big issues are solved - fingers crossed)

You were lucky, Andrew. I had to don my oilskins to put a tarpaulin over the roof of my workshop, which is now wetter inside than out  :(
