The center port would be twice the width of the side ports, 0.188", which gibes with the slider opening of .375", so the opening would just span the center port and one side port.
Ouch... that hurts Sorry about the extra divot there. That's never fun. But it looks super besides that!So, what's the deal with the brass bearing surface? I've not seen that before. It's new to me. Wouldn't it be similar to just use a brass D-valve sliding on the steel cylinder? I'd like to understand the reasoning for doing it this way. It looks like some extra work. Though it does look really cool! Kim
How about filling it in with JBWeld?Vince
