The middle piece must be now at 5mm distance from the edge of outer pieces.ĭo a center punch mark at 20mm from the left/right edge and 45mm from bottom edge at the front piece.ĭrill a ø5mm hole at the three pieces simultaneously.ĭisassembly and then at the back piece cut a M6 thread.Īt the front and middle piece increase the dia of the hole to 6mm. Using a M10 bolt/nut mount/align/center the three pieces and tighten the bolt/nut. Temporarily we will make the diameter of the holes where will be rest the shaft of roller ø10mm.Īt the piece of 75x30x8mm do a center punch mark at 15mm from the left/right edge and 10mm from bottom edge.įrom the 40x5mm flat bar cut 2 pieces 75mm each one.Īccording the plan we need 2 pieces 65mm but this extra length will help us later to do at once a straight and symmetrical cut, at the three pieces that slider consists.ĭo a center punch mark at 20mm from the left/right edge and 15mm from bottom edge at the first piece.Īlign and secure both of them at the vise and drill the hole at both simultaneously.Īfter you has finish the boring of the holes at ø10mm use a countersink or a ø16mm drill bit and clean up the edges of holes. Using a countersink clean up the edges of the holes.Īssemble main base - bearings - bushing bases.
Increase the center holes to ø10mm and then to ø16.5mm.
Increase the holes that will pass the four M6x45mm bolts to ø6mm. We will use it later.įrom a flat bar 8mm thick cut a piece 75x30mm and refine / smooth the edges by a file also do an orientation marck. Using an angle grinder with 1mm cutting disc, make the two cuts.ĭon't throw out the piece of wastage. Make a jig so to hold it the pieces in correct place aligned and do center punch marks using a Center Punch ø3mm at the points that must become the 5 holes. Using a vise you can drill them simultaneously. Using aniline paint the marks will be very clear and easy to view.Ī number punch mark at the pieces is useful as you will be able to use the same orientation at the whole of building process till to the final assembly avoiding the errors.ĭill the 5 holes at the two pieces of 40x40x5mm. Prepare/cut a piece of flat bar 120x8mm at 115mm and two of flat bar 40x5mm at 40mm.Ĭlean up the surfaces of pieces so to become smooth enough.
You can also modify the dimensions according to what you have from materials or to your needs. The cost of the materials is very small and you can make it with any leftovers that you may have.īasically I calculate my plan according on what I had available.
