    Wife says from box of random cut offs she bought when we visited the rock and gem show in Vernon few months ago as she wanted some flavors of rocks that are harder to find local to us. But from what I remember were all cut offs of rocks found in BC So the top right one and black one are from...

    Homemade cabbing machine from scrap.

    Not sure which one you mean lol I'm bad with names of stuff. I looked a few of those grinder heads but the smaller versions as they seem to come up semi cheap. I figured they would make goods standalone roughing machine. Those motors are basicly same as the one I used and I have few more...

    Homemade cabbing machine from scrap.

    Ye that's why you would have to probly press shaft out of arbor and then press back in a longer one. It would probly require rebalancing tho depending on how they machined the arbor to begin with. 3 phase machine would be neat also offers lots of RPM options. The wife couldn't wait for splash...

    Homemade cabbing machine from scrap.

    Ye the motor I used was 1/2 HP seems more then strong enough. I have few 1/3 motors but the RPM was 3450 and didn't want to make big pulley for them to be right speed and all the other motors I got are 3 phase or just overkill for what it is. But wouldn't have to worry about stalling it with a...

I did look into pressing a shaft out of a 1725 rpm motor and replacing with longer shaft then getting rid of OEM bearings and end plates and machining up new motor ends...

    Homemade cabbing machine from scrap.

    The motor I have came off furnace blower and I think think .002 run out won't effect anything as the cabbing wheels I don't think are very precise. Nice that would be fine I have a large diamond blade I found at dump in metal pile that still has lots of life I'll probly make a arbor for and...

    Homemade cabbing machine from scrap.

    I would recommend stainless if you can I just used piece of 1" shaft stock I scavenged off something so I'm hoping it doesn't come back and bit me if it rusts everything into shaft. Ye the wife wants slabbing saw eventually and flat lap so those are on the menu to build sometime aswell. The...
