Wow, that was fast! Wish I could also become that fast with FreeCAD.
-bearings- all 3 are 6201-2RS (32x12x10, DxdxB);
-bolts- both are Eyebolts DIN 444 - not sure, which type (B or C), but dim. are: lenght from the center of the hole(d=12H9), to the end of the thread(M12) is 47 mm (they are cutted, the actual lenght is bigger, don't remember exactly); the non-threaded lenght is around 25 mm from the center of the hole(d=12H9); the width between the flats is 14 mm; the sphere head is D=25 mm in diameter.
-rec. profile- 60x40x3(2,8 measured) - L= 60 mm. Its common S235JR electro-welded profile, not very precise.
-the washers used as distances are DIN 433 - M12 (precise distances from suitable pipe should be perfect
-the cylinder pin is DIN 7 - 12m6 x 60;
-there are some DIN 988 - 12x18x0,1 added to the distance stacks, so to create the needed gap for the band saw thickness and also to create minimum clearance with the vertical bearing (the outer raceways should not touch);
-the washers between the profile and the bearings are hardened (its something like DIN6340; dim.: 13x23,5x2,5; dxDxh) and relatively flat compared with the DIN125A under the nuts.
- for the pin I have "axis fixation washers", those which are easy to mount and hard to remove
The hand-made technology I used is:
-the band saw cut-out is made by first drilling a 7 mm through hole on a drilling machine hand stand, then draw tangent lines from the hole, perpendicular to the base side of the profile and with hand metal saw cut along till the holes. The cut-out height is around 17 mm from the center of the 7 mm hole to the bottom side of the profile ;
-as Walter nicely modeled already, there should be one 12 mm base hole for the eyebolts, and instead of a long hole, I made one 13 mm hole for positional compensation and ease of mounting of the second eyebolt (don't drill through the weld! there is no point
-needless to say that the band saw should be centered, and so the supporting parts too;
-because the non-threaded cylindrical surface of the eyebolts has the same outer diameter as the M12 thread (11,85 mm), I used piece of 0,1 mm filler blade to compensate the resulting gap with the bearings
Need to check my drafts for the other parts and their dimensions. Once again, nice work Walter!
