Grinder Build: Finally Up and Running
Sorry for disappearing for so long, but I've been working on my 2x72" belt grinder for what seems like an eternity. I finally got to chew up some steel and try it out. It's amazing how fast a blaze 60 chews through 5/32" stock.
240V single phase VFD in NEMA 4 enclosure 2 hp, 3 phase WEG motor Operator control panel w/ tachometer (and SFM) display Classy 8 Ball Work in Process - Checking drive wheel and tracking. VFD Enclosure Revving up that motor. Chomping some stainless Now to get some practice on this machine and get back to the fun.

Very nice! I built one from free plans I got from http://www.shankcustomknives.com/my-workshop.html
I did not build such a cool speed controller! Again Very Nice Job! Steve |

Nice Grinder. How do you keep the belt tensioned? A compression spring in the vertical post maybe? Do you press down on the 8 ball to change belts?
Im asking because i am planning some ideas for mine, and i like the simplicity of this. Cheers __________________ R Rogers Knives |

Yes, exactly. A 30# spring inside the vertical receiver that pushes up on the tracking pillar. I got the idea from Alaskabearhawk on YouTube. He has several grinder vids and explains how he did his platen and large diameter contact wheel.
I also rigged a 4" crowned caster wheel into a drive wheel by pressing the roller bearings out and pressing a bushing in for the 7/8" keyed shaft of the motor. Works really well and has no problems with the RPMs. Good luck and post some pics of your build if you get a chance. Dan Last edited by DanCom; 04-30-2014 at 11:22 PM. Reason: typos |

Excellent, I am still in the ideas/planning stage at the moment.
Most of my drawings so far are looking very similar to this. I might pick up some SHS and have a play around tonight. Cheers __________________ R Rogers Knives |

Seemus,
I have quite a bit of detail in my blog page. Shows cut sizes and what not. Get your ideas flowing from there: http://dcknives.blogspot.ca/p/2-x-72-belt-grinder.html Maybe some of the other ideas on that page may be of interest. It is kind of still a work in progress still but I am updating is a few times a week. Cheers! Dan __________________ "Don't believe everything you know." -- bumper sticker |

Happy to help if you need more info. I just realised you are down in Tasmania. Sorry about the Imperial units mate! In Canada we're supposed to be metric since 1974, but I am an old fart from the building trades and cannot shake the inches and pounds.

Thanks for the help all good with the imperial mate. The mill where i completed my apprenticship was built in the 30's, I can work in both In fact i would say half of Tasmania is still Imperial ...although i am building mine metric. Thanks for the inspiration with this very well made machine.

D I Y - Small Wheel Attachment Kit
I got around to building a small wheel set for my DIY belt grinder. Works pretty slick as long as I don't rev it too much.
All the gory details on how I did it are in my blog page: http://dcknives.blogspot.ca/p/small-...for-bg272.html Cheers! Dan |

Dan ,
There is only one issue I see with your VFD Enclosure it is not vented and does not have a filter for fresh air ! this will cause the controller to overheat in the future possibly . __________________ R.
