angle grinder retaining bracket

Share

This was a "one day project" a few weeks ago. While working with the angle grinder, I had the idea to build some kind of cutting board for it.
After measuring the diameter of the tool, I constructed a bracket for it. During the print a board and two scantlings were connected with M8 screws.
Some grooves were made into the bottom of the board to sink the nuts. This way you can lay it on a table and fix it with clamps without destroying the table by making scratches.


The printed object was screwed together inserting one 608zz bearing on each side. Then the bracket was positioned between the two scantlings.
The correct position was marked and holes were drilled so that one can put a M8 bar through them and the bracket.
Double nuts at both sides fixed the whole construction.



To be sure not cutting the board, I inserted an endstop using a screw at the right position and height.



The cutting board is meant for cutting M8 bars, so I added two fixation clamps on both sides of the blade.
One has a slice at one side with a bigger block on top so that you can push it down.

I use a small bead at the side in parallel to the direction of the bars as ruler starting at the blade.
There are small holes at each interesting position so that I can put some spacer into them.
This spacer limits the correct lenght of the bar.



The construction can also be used to remove the burs from the bars. Because the endstop ends about 1 mm above the wooden board, one can start the angle grinder with a abrasive wheel inserted.
Simple hold the bars near the side of the blade and rotate them a few times. The result is ok.



With this DIY cutting board it is almost a pleasure to cut the bars into the right length.
