Hey Folks! Lets make our own Lead Screw End support for our DIY CNCs! I’ll let images do all the talking since therez nothing much to write about xD.
So this was my situation : I was having Bearings with ID=10mm , OD=19mm and same kind Flange type bearing with Flange dia=21mm along with a 20mm Shaft End Support. Using those bearings one could easily convert a ‘Shaft End Support’ into a ‘Lead Screw End Support’. Lets see how.
1) 20mm Shaft End Support Block :
2) Normal + Flange type Bearings :
3) Paper Tape :
4) Small Hammer
Step 1 : Stack the normal bearing over the flange type bearing. Start ‘rolling’ the paper tape over it. Keep on checking the Outer diameter after each full/half revolution. It must not go beyond the Shaft end support’s ID which is 20mm in our case.
Step 2 : Once the Outer diameter barely reaches 20mm its time to cut the tape. Trim the excess tape.
Step 3 : Its time to put the bearing stack into Shaft end support’s 20mm slot. Apply pressure using thumbs to force it in. When its mid-way inside u’ll need a small hammer to force it completely in. If it still wont go inside then a peel of a small section of the paper tape and try again. When its completely inside the slot lock it using Shaft end support’s lock screws.
And thats it! We’r Done!
