Étape 1 - Table Build-Top deck 1

Tools

1/2" Socket

Parts

2x 1000mm 4080 extrusion

4x 300mm 4040 extrusion

40x t-nuts

22x M8x20 bolts

22x M8 Washers

12x Corner Brackets

Steps

1. Slide 6 t nuts into the top side of the 1000mm extrusion. (repeat for other beam)
2. For the 300mm beams, 2 pairs of 2 will be identical, one "I" shaped, and one "C" shaped.
3. For the C-shaped beam, Slide two t-nuts into one rail. Attach the corner brackets at the ends, ensuring the bracket is flush with the beams end. *Always use the side of the bracket with a flat face (non-lipped) first. This ensures you can get a tool onto the 2nd bolt without being blocked.
4. For the I-Beams, repeat the same steps for the C-beam, but on both sides.
5. Repeat so you have 2 I-beams and 2-C beams.
6. *Optional* Add bolts to all remaining bracket holes and loosely attach t-nuts. (as seen in the right two beams in image 3)

Parts

Assemblies from previous step

Steps

1. If you have already attached the bolts/and t-nuts from the optional step - Slide beams into the upper channel (as seen in image 1) Otherwise, thread the nuts into the channel and attach LOOSELY with bolts.
2. Repeat for the bottom rail.
3. Secure the C beams in place with the socket wrench, but leave the I-beams LOOSE as they will need to be shifted later.

2. Secure corner plate to rale with accompanying 6 bolt/washer combos.
3. Add 2 additional bolt/washer/t-nut combos to the 2 remaining vertical holes. Keep these very loose as we'll slide them into another assembly later.

3. Slide 2 nuts into each beam. position these rails on the outside/facing away from each other (see image 6 for orientation)
4. Secure the barrel brackets to the beams as seen in image 5.
5. Secure corner brackets to slotted t-nuts so the open hole is facing down. Keep these loose as there final position will be determined later.

2. Loosely attach the assembly to the table with bolts/washers.
3. Place the barrel into the support structure, aligning the flat notches on the barrel to the bracket.
4. Slide the barrel towards the end of the table until the threads CLEAR the table face.
5. Leave these connections loose as it will be moved into its final position later.

2. Secure the supports with bolts/washer/lock nuts.

Étape 12 - Motor shaft coupling

Tools

Mallet

Parts

1 1/8" Shaft

1/4" key

1 1/8" coupling

Étape 13 - Motor mechanical install

Tools

1/2" socket wrench

Parts

Motor Assembly

Table

4x m8x20 Bolts

4x washers

Spider coupling

Steps

1. Position the motor on the table, sliding the t-nuts from the previous steps into position.
2. Loosely secure the motor to the table.
3. Insert the spider into one of the couplings.
4. Making use of the loose bolts, move the barrel and motor together until they are meshed at the couplings with the spider in between.

Étape 14 - Heat Shield bend and install

Tools

1/2" socket

Metal break

Digital angle gauge

Parts

Perforated shield

6x M8x16 bolts/washers

Steps

1. Identify the small cut notches on the sheet metal that indicate where the bends should go.
2. Using the break, fix the sheet metal in position (figure 2) and bend the sheet at a 45 degree angle.
3. Flip and repeat for all 4 bends.
4. Position the shield in place and secure the back row with 4 bolts/washers and the pre-installed t-nuts.
5. attach the front of the shield with only the left two bolts. (the other two will be utilized for securing the electronic box later)

Étape 15 - Hopper Bend and install

Tools

Metal break

Digital angle gauge or square edge

vice

Rivet gun or hex wrench set

Parts

2x pre-cut hopper sheets

6x rivets or M4 nut/bolt combo

Steps

1. Using the break, fold the perforated sheet on the designated lines to 90 degrees. Both bends should be inward, so that the triangle flap and short flap face each other.
2. The bottom of the hopper sheets need to be flared out so it can fit around the barrel. *We found this easier to do in the vice because you can visually inspect the angle
3. Place the bent hopper half in a vice, and slowly press on the rectangular face until the top of sheet is parallel with the floor/table. (image 3)
4. Repeat for the other sheet.
5. Nest the two pieces so the triangular face is captured by the lip on the other sheet. Secure in place with either bolts/nuts or rivets
6. Place the hopper over the barrel.
