..It's starting to feel like a summer might actually happen here in the SW of WA.  We skipped the last Busselton meeting due to the long weekend, so it seemed like we hadn't caught up for over two months.  There was lots to catch up on.

Here are some links to things that where discussed:

BangGood has some cheap  2020 T-Slot lengths for sale:

They also have some cheap-ish screw shafts and supports:

There is quite a range to check out:  There should be some anti-backlash screw houses around as well:
