Added an Oneida Dust Deputy to my extraction system. Tried a metal bucket ash filter available in regular construction shops but the filter needs frequent cleaning. Shaking the filter bucket as per manual didn`t help. This is why I decided to convert it to a cyclone separator.

Large centre hole was cut and ground with corundum cutting and grinding disks found in IBS/E storage case. Drilling those outer mounting holes bent the thin sheet metal a little but nothing too serious I hope. Wooden square part was cut with Stepcraft from 4,3mm multi-layer birch plywood.

Here is the static electricity dissipating system as I understood from the owner`s manual. Aluminum tape and a wire connected to a round metal plate that is supposed to lie on the floor.

Three metal rings are there so smaller buckets could be attached to them for easier cleaning and dust collecting. Don`t have those buckets yet.

Few connection possibilities:
1. Vacuum cleaner is connected by an accessory power tool connecting adapter and regular household plumbing connectors (this is same for following options too). IBS/E dust extraction hose is also connected to the cyclone via regular household plumbing connectors. Hose from the Stepcraft is pretty small so might need additional bleed air inflow.

2. Original ash filter hose (it has a metal inner surface) can be connected with a regular household plumbing connector for some general cleaning.

3. Finally a Timberduc PUR 531 SE-AS flame-retardant and antistatic suction and blast hose for the wood industry connects to a cyclone without any additional adapters. Stumbled upon this hose by a chance as I was looking for a suitable gasket material.

Yet to be tested in operation. Made first tests with a house vacuum cleaner and some dust. Seemed to work ok.
