52mm Spindle Original clamp bracket
Description
Got sick of plastic tool mounts so I designed this bracket to attack the Aluminium original bracket to the MPCNC. Machifit ER11 Chuck CNC 500W Spindle Motor with 52mm Clamps Easy access to all screws even when all set up. this is so you can always check for tightness without disassembly. print the nut test Stl first as I found my nut in the workshop. if they aren't your size send me your dimensions and I'll whip up the correct size. Needed; I used a drill press to bore out the aluminium bracket holes with a 10 mm bit(might want to step up in drill size, 8 then 10 mm) to a depth of 5 mm. I don't know how long your screws are so you will need to measure your depth required. don't let these screws go out past the nut as there is very little clearance. the thickness of the plastic where the nuts go is 5 mm, so add 5 mm plus your nut thickness and that's how far your screw should measure past the aluminium bracket. 4 x 35 x 4 mm screws for the tool mount. side note, I'm going to remount the bracket so the spindle is higher to get more clearance on materiel. Update 05/04/2020; I don't know why Thingiverse won't show the Stl files in preview. Since using this bracket I've noticed a significant improvement in spindle cooling as well as surface quality on my relief carvings.
