Now you are ready to install everything, but! if you want to save a few dollars and make you setup a little bit user friendly you can build your own custom fork clamp bracket instead of using the existing 54 mm clamp. I build my own bracket due to I wanted to make it a littlr bit easier to install and to not wait until the existing bracket will be delivered from China. I can share my CAD model if you want to replicate my bracket design. The existing 54 mm bracket should work fine, it just needs more effort to be installed due to different screws orientation and spent some time to find appropriate angle for the bracket.
So if you want to build you own bracket you need to find a piece of 1/2" thick aluminum plate. Then mark the bracket contour using the CAD model
Mill 54 mm diameter hole in the plate. It is the most critical part of the work. The hole diameter tolerance should be within +0.2 mm -0.0 mm tolerance zone. The rest of the work is not so sensitive to precision.
Mill radial area of the outside shape of the bracket
It is a good practice to apply chamfers on bracket edges.
Apply chamfers on opposite sides too
Proceed with milling outside contour of the bracket. Drill 6.8 mm diameter hole in the bracket before you completely will have cut the bracket from the plate and tap this hole with M8 thread
Mill the bracket out of the plate completely
Predrill the clamping screws holes for 1/4-20 tread.
Finish chamfering the part edges
Cut the bracket on two half and finish each half individually.
Ground the split faces and drill out clearance holes for 1/4-20 screws in one half oft the bracket
Ground the split faces and tap holes for 1/4-20 screws in opposite half of the bracket
