== Collector Mounting ==
== Collector Mounting ==
Install the collector in the pallet rack behind the Shopbot. This will make the mounting of the motor easy and provide a framework for a sound enclosure, if necessary. The collector motor will be mounted on top of a piece of 3/4 plywood that is secured to the top shelf of the rack.

The approximate dimensions of the rack are 44" wide x 33" deep x 8.5' tall. Dimensions of the collector without the inlet tube are approximately 24"x34"x8'. (is this also true for the nano filter?)

3 phase motor is 99 pounds.
The collector is up and mounted. The joint between the blower housing and the cyclone needs to be caulked ( which may require dropping the cyclone a few inches).
== Ducting ==
== Ducting ==
An 8" main duct will begin at the collector and run parallel to the trusses and below towards the shopbot and across the shop towards the woodworking area.
Bill Penz: elbows with a center line radius of 2 to 2.5 diameter are preferred. For 6" duct, 12 to 15".
An 8" main duct will begin at the collector and run parallel to the trusses and below towards the shopbot and across the shop towards the woodworking area.
To reduce turbulence in the collector, first 5 feet should be straight with no fittings.

Put down drop blast gates as close to the main duct as possible.
Put down [[File:Blast_gate.doc]][[File:Blast_gate_front.svg]][[File:Blast_gate_back.svg]] as close to the main duct as possible.
Clearvue: Use SRD-35 or ASTN D3034 PVC or 24 gauge spiral duct or thicker.

Clearvue: If PVC is used, the pipe can be grounded with a wire run on the outside of the pipe, attached to a screw driven into the pipe every 5 feet. The screw running into the interior of the pipe will drain off any charge.

== To Do ==
Order 6" flexible hose for shopbot.
Upper table saw guard/collector from Shark Guard has a 4 month lead time. We need to find another supplier or fabricate one.
Buy or make a collector shoe for the shopbot. The shoe supplied with the shopbot has a very small inlet (3.5"?). It will probably work for the short term.
find 2 conductor cable and switches for the motor control. Power supply for the SSR (12-36v?).
Install ducting. Duct order should arrive 7/10.
Make hoods for chopsaw and planer.
