From www.richontools.com - based over in HK/China. Pretty cheap, cheap and efficient delivery - but the main reason I got from there is because they had the exact sizes I needed, couldn't find them anywhere in Aus.Where did you get your diamond hole saws from dude?
This video probably shows it best - the level can sit pretty much anywhere between top and bottom, and the slots are rotatable - but yeah I'd probably make them vertical to get maximum flow through.So talk to me about that unit bud, these vertical slots are in the correct position by design? > and if that's your skim, where is your DT level meant to sit on these?
