For this part of the build we will be using:
2 x V-Slot 20 x 80mm (Length: 750mm) 52 x Spring Washers
2 x V-Slot 20 x 80mm (Length: 705mm)
2 x V-Slot 20 x 60mm (Length: 500mm)
72 x M5 Tee Nuts
64 x Low Profile Screws M5x10mm
68 x Standard Washers
8 x Universal L Brackets (Triple)
4 x 5-Hole 90 Degree Joining Plate
4 x Low Profile Screws M5 x15mm
2 x V-Slot 20 x 80mm (Length: 750mm)
52 x Spring Washers
For the spoilboard (please note we do not provide the spoilboard with our kits):
4 x Universal L Brackets (Double)
8 x Low Profile Screws M5x10mm
8 x Woodworking screws
We recommend laying out all parts in the base build and dropping down required hardware to help assure that all tee nuts are installed before assembling.
Please note that this build deviates from the standard Ox build in the fact that it had two V-Slot 20mm x 80mm table supports. This was to achieve a more rigid and stable machine. Assembly is essentially the same.
Start by adding any required tee nuts for work surface holding. We chose to place two tee nuts along each of the two top side and the top most slots on each of the support beams.
The parts required to mount each end bracket (two required each support beam, eight in total):
- 6 x Low Profile Screws M5x10mm (total 48)
- 6 x Spring Washers (total 48)
- 6 x Standard Washers (total 48)
- 1 x Universal L Bracket (Triple) (total 8)
- 6 x Tee Nuts (total 48)
Drop a spring washer, then a standard washer onto the M5x10mm low profile screws before putting each screw stack into the triple universal L bracket holes, ensuring you insert the stack into the adjustment side of the universal bracket (the side with holes closest to the edge of the bracket). Mounting this way allows you to adjust the final length of the inner braces to fit exactly into the other parts of the frame.
Place a triple universal L bracket on each side of the table supports, using a M5x10mm low profile screw, spring washer and standard washer stack, with one tee nut installed into the V-Slot linear rail.
We find it easier to pre-assemble the end connectors and then slide the completed assembly onto the end table braces. Some find it faster to install the tee nuts into the base slots and put in the screw and washer stack when in place, it’s really what works best for you!
Install a spring washer onto each of the M5x10mm low profile screws,
followed by a standard washer.
Mount the screw and washer stack onto the triple universal L bracket with a tee nut.
Rinse and repeat for the remaining brackets (a total of 8 triple universal L brackets on our build).
Installing the Nameplate (Optional) – please note this is part for the Robert Hummel plate set and does not come standard with our standard. Parts required:
- 4 x Low Profile Screws M5x10mm
- 4 of Small Washers
- 4 x Tee Nuts
Install small washers into the name plate holes.
Add a M5x10mm low profile screw to each,
followed by a tee nut.
This build log shows the installation of the Robert Hummel end caps. Our standard kits come with 5-Hole 90 Degree Joining Plates that serve the same purpose.
End parts using Robert Hummel end caps(per pair of end plates, there are two pairs per build):
- 14 x Low Profile Screws M5x15mm (total 28)
- 4 x Spring Washers (total 8)
- 12 x Standard Washers (total 24)
2 x Small Washers (total 4)
10 x Tee Nuts (total 20)
End parts using 5-Hole 90 Degree Joining Plates:
- 4 x 5-Hole 90 Degree Joining Plates
- 4 x Low Profile Screws M5x15mm (total 28)
- 4 x Spring Washers (total 8)
- 20 x Standard Washers (total 24)
- 16 x Low Profile Screws M5x10mm
- 12 x Tee Nuts (total 20)
Place spring washers on the four M5x15mm low profile screws (these will thread into the 20mm x 80mm main axis V-Slot linear rail ends).
Place standard washers onto all screws apart from the two top M5x15mm screws. These will have a small washer for extra belt clearance.
Drop the M5x10mm low profile screws into the holes pictured.
Add tee nuts then repeat the above steps for the remaining two brackets.
Lay out the assembled parts on a flat surface.
Slide the name plate onto the front two base support beams, making sure the shorter of the two is on the top.
Slide the front two end caps into place.
Slide the rear two end caps onto the rear base supports, ensuring the shorter of the two is on the top.
Slide each of the long base support beams onto the front and rear beams.
Add any required tee nuts to the front and rear supports. We used two on the top slot, both front and back for extra spoilboard mounts. You may require extras for an additional mounting needs such as bolts for a vacuum bed, for jig holding etc.
Slide the gantry side into place. We recommend using some masking tape to hold the carriage in place to stop it sliding around in the next few steps.
We recommend getting a friend (or roping in the girlfriend like I did) to help carefully lower the side rails into place.
Install the last eight M5x15mm screw and washer stacks, checking the smaller washer is on the top hole and clear of the belt slots.
Optional extra: Add adjustable rubber feet.
