I usually hold the vacuum nozzle behind the box sinker (toothed kind rather than rotary Armeg) when sinking holes but I was wondering if this gadget offered any improvement in efficiency when minimising dust is a concern:
Is it likely to work better with a dust-prodcing Armeg than a chunk- producing toothed sinker?
Anyone else got one? I thought there was a discussion about making your own a while ago but I haven't managed to find it in Google groups archive.
