Will post full reviews of both systems later, but just wanted to drop a note.

The Nova Vacuum Adaptor gets a thumbs down. It works in conjunction with the handwheel. Didn’t work with a shop vac, didn’t work with my vacuum pump. I spent all kinds of time making custom fittings for it. Still no go. The bearing is just too leaky. Maybe if I slathered the whole thing with some grease, but I am tired of messing with this thing.

The Hold Fast Universal Vacuum Adaptor gets a hearty thumbs up. I installed it, trimmed the headstock tube, and had over 25” of vacuum in about 15 minutes setup time.

Good to know. I’ve been eye’ing these things and am generally a Nova fan. The OneWay also looks somewhat good, but then, it should for the price. You don’t say, but what kind of vacuum pump are you using?

-- Lathes have a weird vortex around them; I lose all track of time when close enough.

Yeah I am a fan of Teknatool products but this system was not well thought out. Info on their website was limited and the instructions were abysmal. It was not clear if it should be used with a shopvac or a vacuum pump. I rigged it with both and barely got 8PSI either way. Checking the website today I see that they are no longer producing this system. The handwheel is great, and should have been standard equipment.

I am using a 2.5cmf single stage vacuum pump from Harbor Freight. I was thinking about picking up a Gast but got tired of waiting for a deal and had a 30% off Harbor Freight coupon so I pulled the trigger. With my level of production (hobbyist) it has been working fine.

When I get a minute I’ll post pictures and a review of the HoldFast adaptor and setup. The bearing adaptor fits right inside the Nova Handwheel so the handwheel is still usable while the adaptor is installed. List price is about $60, wish I had passed on the Nova adaptor and saved myself $40.
