How long is it taking you to filter, and what sort of quantity are you looking at?
The biggest revelation for me lately, that seems to be working, is bigger filter bags.
I've got two half pillow cases, suspended in 45 gallon drum. Good oil, I can get 30 litres through each, as fast as I can tip it. They will hold about 40 litres, but the rate at which it goes through slows down after the first 30.
Basically, in a matter of minutes, I can have a 60 litres in the drum, and another 80 that will drain down in a day or so.
Then I put 25 litres through a J cloth, twice, which takes minutes, and settle this with 10% petrol. The final two passes through a J cloth takes minutes, before it goes in the tank.
I could do twice the amount in very little more time, and make it a lot more efficient, but I've no real desire to.
I know I'm not exactly being very technical with the J cloths, I works, just about. It's not quite fltered well enough, I don't think. Something I may do something about in time.
What I would say is, 10m doesn't sound enough to me, I'd say 5 at a minimum, but others may disagree.
Which part of your operation is taking the time? If it's getting it through the 1 mic, I'd be inclined to investigate a very big 1 mic filter bag. I'm sure the filter bag makers would stitch one up for you. Rumour has it, filterbagman on Ebay stitches them up in his garden shed, and is a very tidy sort of a chap.
There is a member here who sells the nylon filterbags, (can't remember who, diysurgeon?) they seem to be gaining a reputation, although I have not used them myself. Maybe give him a try and see if he can get you a larger bag.
I've tried loads of variations of filtering setup. For my money bigger bags, 40 litres upwards, will be a part of any future setups.
