Initial Cube and Wall Assembly Instructions

Tips

  • Make sure the Hex Bit is completely seated inside the screw and apply a small amount of force into the screw as you either tighten or loosen the screw.
    • Failure to do so may result in damaging the socket head cap inside walls, resulting in “rounding” the hole or “stripped”. This will cause the bit to not grab/bite correctly when inserted and will cause the screw to be very difficult to remove.
  • Caution must be used when screwing steel/stainless steel into aluminum. Aluminum is softer than these metals and will deform. If there is any resistance felt when screwing into aluminum, stop and back the screw out. Inspect the threads for any damage. Reposition the screw to be straight and try again. NEVER FORCE A SCREW INTO ALUMINUM.

  3. Place the plate onto the blank IdealVac wall and hand tighten with an allen key 8x 1/4-20 (3/8” length)
  4. This is the base for the 40K box. Set this aside to be ready to mount the 40K box.
  5. Next is mounting the 40K bar-stock to the bottom 40K plate. The hidden photos below will show the top and bottom orientation of the 40K bar stock and 40K plate.

    2. 40K Bottom plate 40K bottom plate orientation.webp
  6. Apply Apiezon N grease to the top corners of the 40K bottom plate where the 40K bar stock will sit.
  7. Mount the 40K bar stock onto the greased position and screw a 4-40 5/16” length screw with a Belleville disc spring as seen below. Make sure the corner of the bar stock lines up with the corner of the 40K bottom plate
  8. Repeat for all 40K bar stock

If building a 1K system, follow the 4K Box Assembly before moving to the step 10. If not do step 9.2-9.4.

  1. Only perform steps 9.2-9.4 below if using a single 4K plate
    2. Place three nylon spheres onto the three top cone locations of the 40K plate
    1. 40K with nylon spheres.webp
    3. Place 4K plate onto the three spheres
    1. FIXME insert photo of 4K box on 40K with spheres
    4. Screw a PEEK screw with 5 x spring washers into the center hole of the 4K plate into the 40K plate. Screw until the head of the PEEK screw is just below the surface of the 4K plate.
  2. Now we mount the 40K box frame onto the blank IdealVac wall and cube we prepared earlier.
  3. Mount the 4K plate or box onto the bottom 40K box.
  4. Place three nylon spheres onto the three top cone locations of the 40K plate
    1. 40K with nylon spheres.webp
  5. Place the 4K box or 4K plate onto the three spheres, making sure the balls line up with the square, cone, and oblong cone.
  6. Screw a PEEK screw with 5 x spring washers into the center hole of the 4K plate into the 40K plate. Screw until the head of the PEEK screw is just below the surface of the 4K plate.
    1. Peek 8-32 screw with 5x spring washers.webp
  7. Wipe down the top & bottom 40K walls & the 40K joining plate and attach the knobs onto the walls
    1. FIXME insert photo of top, bottom and 40K joining plate
  8. Apply greese to the 40K bar stock and attach the 40K to

4K Box Assembly

Building Instructions

  1. Start with cleaning all parts with isopropyl and a lint-free wipes
  2. Similar to the 40K assembly, use Apiezon N grease on the top corners of the 4K plate. See below for the bottom 4K plate orientation.
    1. Bottom 4K plate orientation.webp
  3. Mount the 4K bar stock onto the greased position and screw a 4-40 5/16” length screw with 2 x Belleville disc spring as seen below. The 4K bar stock must follow the orientation seen below. The holes must be orientated like the red arrows for the 4K walls to work.
    1. 4K bar stock.webp
  4. Use Apiezon N grease on the bottom corners of the top 4K plates. See below for the top 4K plate orientation.
    2. 4K top plate grease.webp
  5. Mount the top 4K plates onto the bar stock. Keep in mind the direction of the top 4K plates. This will determine the orientation of the 1K cooler and ultimately where the 1K mounting plate faces. These will use a 4-40 5/16” length screw with 1 x Belleville disc spring washer in the blue counter sunk holes. There are 4 of these.

  6. Screw in the feedthrough plates onto the top of the 4K plate. Each plate requires 8 4-40 5/16” screws.
  7. Clean the copper 4K bend plate and put Apiezon N grease on the bottom side of the bend plate where it will mate with the 4K plate. The copper 4K bend plate will be placed on top of the 4K box and align it’s holes to the 1K 8-32 heilcoil mounting holes.
