    the material of the drive wheel it´s a "tecnyl" , its a nylon composite ... but you made with aluminium with a tree o-ring insert in surface

    in more days i adapted a automatic pump with compressed air , the power of the machine its a 120 tons .. ( the púmp generate a 700 bar pression )

    bandsaw





    the bandsaw its made fron scrath , step by step , the only pieces are buy its a gear worn box and the motor eletrical and the phase converter . the more pieces are made by me !

    Roberto aqui un Colombiano que también monta mucho en Motos...

    I need to upload the pictures of the few belt sanders I have made so we can share ideas..

    I have two suggestions from your video...

    First you thumb is not design for that kind of motion or load, I bet it get tired fast plus you can develop early arthritis in the long term too.


    For you actuator lever I see three options..

    * maybe you can uses a Clutch lever maybe even a bicycle one since they are so much smaller to take care of the adjustment, your fingers can deal with the motion no problem, no different than a front brake or a clutch....

    Option two, adapt a motorcycle Throttle so you can hold to the grip of the grinder but also adjusted at the same time..

    And 3th maybe the perfect one, is a bicycle company call "SRAM" that makes a gear selector system call "GRipshifts" is basically a twist grip but with detents (10 at the most) that way you can have a stable grip to hold and then the other half (About 50mm long) of the handle can have the adjuster lock (you can readjusted all you want by twisting the grip) so you hand will not get as tired..

    Also when I'm sanding, polishing tubes or anything is concentric, I spin them on a "Chuck" (Old wasted lathe jaw for the big diameter pipes, drill press, even a hand drill held by my knees) this way I get a very homogeneous diameter and finish with out any humps, etc..

    Is easy to see that you have the skills but is always better to work "Smarter not harder"

    Again congratulations, I like the application and the simple easy to understand structure, thanks for sharing.

    Wowsers, very nicely done, again easy to understand the functions for a new operator (I know you are the one that uses it, but is nice that the machine makes sense when you look at it) and also very precise.
