Introduction: Router Milling Machine
A little under a year ago I first used a mill, for those of you who don't know what that is as I told my mom: "It's kinda like a drill that you can move around and use it to cut stuff," and though it is the best and most fun tool I have ever used the only one I have access to is 25 minutes away. Since it is so far away I only get to use once or twice a month if even that. I decided I wanted to somehow get one so I checked craigslist for a small one I could use for little wood projects and.... 700 dollars!! I could build one for under $70! And I did.
Also, Sorry if the instructable seems incomplete it was written late at night for a contest deadline and will be updated tommorow throughout the day
Step 1: Things Needed
- An I-beam
- Three Scissor Jacks
- Various pieces of metal
- MIG and SMAW (stick) welders
- Horizontal bandsaw
- Drill w/ drill bits
- Bench and hand grinders
Step 2: Specific Metal Pieces
The specific metal pieces are:
- A 50 in. I-beam cut at the 18 in. mark
- A 15 in. x 4 in. x 1/4 in. plate
- A 23 in. 90° piece
- An 18 in. circular pipe
- A 2 in. square tube
- Three 1 ft. x 1.5 in. x 1/4 in. pieces
- Two 4 in. circular pipes
- two 3 in. square tubes
*I found everything around my workshop so anything can be swapped.
Step 3: Weld
First, Weld the shorter I-beam piece a half inch above the bottom of the longer I-beam then weld the 18 in. circular pipe to the I-beam at the top.
Next, weld a 4 in. circular metal pipe to a 4 in. square metal pipe and do that again.
Then put the pieces on the inside edge of the "knee" and weld the square part to a scissor jack so that it slides.
After that, weld a jack to the "base" I-beam right next to the "knee"
Next, weld the top of that scissor jack to the bottom of the 2nd scissor jack
Then weld two 1 ft. pieces to a 5 in. x 1.5 ft. rectangle with enough space in the middle for another 1 ft piece
After that weld the bottom of the third jack to the piece that was just welded and then slide a 1 ft. piece between the two other ones and weld the top of the 3rd scissor jack onto that piece.
Next weld the top of the 2nd scissor jack to the 1 ft. piece
Step 4: More Welding
This step of welding is mostly to stabilize the mill.
First, weld the 90° piece onto the bottom of the base I-beam.
Then weld the 2 in. square tube onto the front bottom of the 18 in. I-beam
Step 5: Mount the Router
This step is pretty easy, just drill a two holes on the top metal pipe spaced apart 2.5 in. Next, put the bracket on and put bolt through the hole and screw a nut on the other side. Then put the router in the bracket and put another bolt in the other hole
