I bought a compressed air filter with a 40 Micron Element from Ebay for ~$14 delivered and connected it up. Then after turning the base off my first project I noticed a few fine sawdust fibres in the bowl, so lucky I did, thanks for the heads up guys
Another problem has come up though. After turning up the base I took the piece off only to find a big black ring from probably minor slipping
They sanded out Ok, but has anyone else had the problem?
Is there a simple solution?Neil____________________________________________Every day presents an opportunity to learn something new

Haven't had that problem yet Neil but I suspect it would be due to the type of rubber you used for the seal. I used EVA foam for the 2 of my three chucks that I use most and the 3rd one has a rubber seal from an old vacuum cleaner which is very similar to EVA foam - no problems yet - touch wood!!!

Could well be the rubber I used, it couldn't be those catches I have. Do you use a clear colour, or any colour you can get?
Gawdelpus has suggested putting some baking paper over the rubber too, certainly worth a try, but replacing the rubber is easy too.Neil____________________________________________Every day presents an opportunity to learn something new

What ever seal you use as long as its closed cell foam leaking wont be an issue. As for dust and foreign bodies being sucked into the vac pump. The simplest way I am aware of the to fit a small container say .5 to 1L in the line before the pump. So it can act as a settling point, much like your cyclone dust extractor. Most Pneumatic suppliers will have one as this is a standard method of particle removal. Much better than a filter as it can be cleaned more readily with a quick washout.
