In this Instructable I will instruct you on how to take a street cone and turn it into an awesome cyclone to use with your shop vac.

THINGS YOU WILL NEED::

street cone

if you dont have one here is a link to get one on Amazon for 25 buckshttp://www.amazon.com/Mutual-Traffic-Reflective-He...

a 5 gallon bucket with a good lid

one 8 foot 2x4 pine

3 feet of 2inch pvc

2 pieces of plywood around 10 inches square

40 3/4 inch screws

6 1 drywall screws

16 2 inch drywall screws

a 10 nch round piece of plexiglass

Step 1: Cutting the Plywood Circles

The first thing is to cut 2 10 inch plywood circles using a bandsaw or jigsaw ,or scroll saw after the 2 circles are cut you will need to cut the center out to a 4 1/2 inch hole with the saw table angled to 10 deg.

In this step you will want to cut a 4 1/4 inch hole in the bucket lid to match the hole in the plywood and after this step you will sandwich the bucket lid between the plywood and drill a few screws to keep them together.

Then you can test fit the lid over the cone, it should fit it nice and tight around 5 inches from the top of the cone.

Step 2: Cutting the 2x4 and Ripping It to 2x2s

Noiw you will want to cut the 2x4 down to 24 inches and then using a table saw rip the 2x4s in to 2x2s

You will need 8 2x2s

Step 3: Getting the Angle

Now that you have the boards cut that support the cone you will want to place the cone on the bucket upside down on the bucket to measure the angle.

Using a angle finder to find the angle of the side of the cone mine is 10 deg your cone might vary

next you will measure the height of the board , mine is at 19 inches from long point to short point again yours may vary.

Step 4: Cutting Support Boards

In this step you will want to cut the angles on the supports

set your chopsaw to 10 deg

cutoff the end of your board

and then measure over 19 inches and mark your angle then cut on the line

also you will want to cut a chamfer on the cone side inner edge to accomidate the curve in the cone

Step 5: Attaching the Supports

in this step you will attach the supports to the cone

set one support block in place and screw a 2 inch screw thru the plywood into the support and then do this for 7 of them leaving one of the coner ones out for later

after those are screwed in turn the cone over and mount it to the bucket

now screw a screw thru the foot of the cone into the support to mount the other side

Step 6: Cutting a Hole in the Side of the Cone

in this step you will be cutting a hole to fit 2 inch pvcin the side

i didnt have a hole saw so i used a baseball bat that i cut the end off and sharpened as a hole saw

so i pushed the bat and twisted it till it cut a clean hole

you can also use a sharp knife to cut the hole

you want the hole in the corner so that the pvc will go in at the angle to run the dust around the inside smooth

Step 7: Cutting the Pvc

in this step you will cut a piece of 2 inch pvc to 12 inches long

the next step is to push the pipe in the hole and mark on the inside where the cone touches the pipe and thats where you cut for the inlet shape

leave the tip for a spot to mount the pipe as in the pictures

Step 8: Making the Pipe Fit Your Shop Vac Hose

in this step you will need a propane torch or heat gun

you will want to heat the end of the pipe till its flexible enough to stretch over your shop vac hose if it dont go heat it up longer and spin it as it heats in the flame

but you dont want to burn it as much as i was low on propane

(disclaimer ) be careful not to burn your self I warned you

you can also make other fittings in this manor

Step 9: Cutting the Plexiglas Top

cutting the Plexiglas top

i used a piece of 1/4 inch plexi glass i had on hand

i made a wooden template to mach the hole in the cone

i hot glued the plexi to the template and using my pattern bit on my router table i carefully routed it out

after the outer dia matched the pattern i did the same to the 2 inch hole in the center for the pvc

Step 10: Making the Inlet Pipe Fit the Shop Vac Hose

this step is the same as the other step in this step you will need a propane torch or heat gun

you will want to heat the end of the pipe till its flexible enough to stretch over your shop vac hose if it dont go heat it up longer and spin it as it heats in the flame but you dont want to burn it as much as i was low on propane (disclaimer ) be careful not to burn your self I warned you you can also make other fittings in this manor
