I found a video on YouTube by Accu-Slice of modifications he made to his 8L lathe stand. He glued a liner into his chip tray to keep coolant away from the walls. He also put a removable tube that directs the coolant right down into the coolant tank to help alleviate splashing. I’m trying some variants of what he did. As a quick and dirty experiment I sealed the outside two rows of drain holes with some rtv.
I also attempted to seal up the the drip tray with rtv.
The last addition I made was an easily removable 3D printed tube to direct the returning coolant low in the sump to help reduce splashing.
After I’ve used the lathe for a while I will report back on the effectiveness of these modifications.
