Miter Saw Dust Adapter

I have been looking for a vacuum adapter to use with my 10" Craftsman miter saw. Shown below is the miter saw with a home made adapter using a PVC pipe fitting.
Craftsman Miter Saw
Adapter made of 1 1/4 PVC fitting and slip nut.


The adapter is made from a 1 1/4 inch PVC pipe fitting purchased at HD. Three holes have been drilled and tapped around the edge about 1/8" in for 8-32 machine screws. A slip nut which can be found with the sink fittings will hold the hose tightly.

Dust Separators

A dust separator, DS, is a device to remove particles from the vacuum air stream without filters. The Dyson vacuum cleaner is an example of this process, using cyclonic airflow for separation. Cyclonic airflow works like a washing machine spin cycle, except instead of throwing water out it throws dust. For this discussion we will examine two devices available to the woodworking shop: The Dust Deputy and the Thein baffle.

Miter Saw Cabinet

Basic compound miter saw cabinet without vac.

Well, I have some cabinet grade plywood left from wall cabinet building, so why not a CMS, compound miter saw, cabinet with wings. Here are two designs I found on the web

Since I have a small shop, Mike's smaller design seems best; however, I like the full wings on the other design. The first part of this project will be to build the basic cabinet, a design that could also be used for other tools, such as, the drill press, band saw, etc. The wings will be added later.

Specification:
  1. Same floor space as present metal stand, 24" x 20".
  2. Two fixed and two locking 3" casters
  3. Draw for tool accessories
  4. Internal duplex power outlet
  5. Extension arms both sides with fence, ruler, and stop.
  6. Removable saw platform to accommodate 10" and 12" fixed and sliding saws
  7. Built in vacuum/dust separator with autoswitch
Note: See post on dust separators
