    Angle grinder pipe sander attachment. - quick mount -

    Hi

    Made an attachment to my angle grinder.
    Its for sanding pipes and curved edges. For smoothening welds, rust & paint removing...

    Wanted to keep it simple as possible.
    Later im going to update it with dust guard and removable backing plate, for using it like regular belt sander.

    Ring under the "locking plate" leans to the spring washer.
    Body is made from two 3mm thick plates.
    This gives more strenght, but also adjust wheels to the same level.

    Slide to the tension system, is made from 2mm sheet and 4mm plate. Shape of the casing (2mm) gives support to the actual slide (4mm) from all sides.

    Can be used with 20 and 40mm wide belts.
    Belts are bought, wheels (52mm with 16mm hole, M16 nut locks the drive wheel ) from the skateboard.

    Video shows the making and use.


    Can be mounted/ unmounted within 10 seconds.

    Plans:

    Here's simplified plans from it.

    I designed this to be used with 520mm and 533mm long belts

    Those are 1-2 euros each, so i didn't found reason to make my own.

    White washers are made from nylon, and shaped to cone.

    Reason for those is to keep spring centered, this allows it to move without touching the sides.

    This gives better operation to it.

    Parts of the slide are sprayed with silicone spray for better slide.

    8mm axle has 20mm long M8 thread at the end.


    Thickness of the disc guards locking fingers was 3mm, so i made locking plate from 3mm plate.

    Because i had no big enough hole saw ( 42 mm needed ), i marked the needed diameter with compass.

    And made biggest hole that i could to remove most of the material ( i had 32mm ), and used rotary tool and tungsten carbide cutter to remove rest. I finished the shape with hand files. This was actually somewhat simple task, and took only an hour to finish.

    Mounting "fingers" wasn't located symmetrically, so i used fit, mark and file more method, instead trying to accurately measure or mark the locations.

    Is this angle grinder mod #11? I've lost count among these previous builds of yours. If you haven't already, you might find more ideas here: Homemade Tools: angle grinder - HomemadeTools.net

    This activity of creating numerous modifications for a single tool is akin to an artist doing a study. But instead of for a bowl of fruit, it's for an angle grinder.

    If you really get bored, you can always make an angle grinder dragster:

    Thank you very much. Im happy if you liked the video, i had to skip some parts to keep it in reasonable lenght.. Editing is a tricky task, its easy to ruin whole video with wrong editing.

    I think its just "another".
    Battlebot with tuned angle grinder would be one option too..

    HA HA! Way cool. That's the Certified Builders Association of New Zealand. Very clever KIWIs...(I'm married to one, me, an expat Yank, and we live in AUS...go figure...
    Seriously, many thanks to all for the daily inspiration. Cheers

    I actually understand just how difficult it is to do a decent video edit which is why I appreciate well done videos.

    As might be expected this thread created interest in your press design. I've been looking that over for inspiration but I think you missed one part on the bill of materials list. That is the plate the Hydraulic Ram passed through on the sled. Either that or I missed it.
