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!

New from Old / Re: Resurrection of a CFEI 100 KVA Induction Furnace

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

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.

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)
