I'm nearing the end of building a Pentz/Clear Vue style dust system. (my thanks to Bill for his work, and CV for the bought parts which have been of excellent quality) It's running. Boy do these systems move some air!!!
The non standard layout (blower mounted in a loft, cyclone projecting through the floor) permits the use of a std 572mm dia X 851mm deep 55gal open top steel drum for chip collection - in place of the usual trash can size. The plan is to use poly bags for chip disposal. There's build photos on this UK forum here - two batches, one near the start, and another towards the end of topic: http://thewoodhaven.co.uk/phpBB3/vie...php?f=3&t=2048
Finding an off the shelf source for small quantities of polyethylene drum liner bags is proving difficult in Ireland (it's a very small market) - no problem if you can order 2,000 and can wait four weeks for them. The ideal item is probably a circular bottomed drum liner in heavy 125 micron (?) polyethylene, but so far they can't be found in small quantities off the shelf. An option is possibly a gusset bottomed 900mm wide (when flattened, that'd give circumference of 1790mm) bag, but it's again proving difficult to find these in a suitable size.
Can anybody suggest a standard bag that would suit, and name the application they are used in? This might help the search over here.
Are liners like this available off the shelf in the US on a mail order cash sale basis? (I'm sure they are)
Experience based input on the pros and cons of bag types, and on how to handle them/what to look out for when using them for dust disposal would be appreciated. I'm presuming they work well provided the drum lid is well sealed so they don't get sucked up into the cyclone (I have clip on lids with built in seals and full circle clamping rings), but don't know if the lids will seal well enough if I use an oversize bag that requires folding of the polythene to fit it in.
The thinking is to use clears bags, and fit a perspex window in the side/top section of the drum, plus another in the lid for shining a light through so that the level can be checked. Is this likely to work?
Thanks
