HEBCO Grinder refurbishment
Hi All This grinder was acquired by the previous owner for scrapping and he already scrapped the copper from the motor The grinder was not in good shape as per the pictures below. The motor was missing but the end casings were there. Most of the bits were there but rusted bent or broken. It stood in my yard for a while while my workshop was built, and the project bubbled up to the top of the pile. The first hurdle was getting the arbour nuts off the arbour as they were severely rusted on. Lots of beatings happened to no avail. Lots of rust products were tried to no avail. I let is stand for a while then hit it with MAPP gas and a big rattle gun and it came free for both nuts. Then i had to remove a bearing from one journal so i could feed in two new drive belts and reassemble the drive belts on the arbour pulley. I had a spare motor that came off a floor drill but i was told that it was 110 volt but on closer inspection it was actually a dual voltage motor 110 240 so I had it rebuilt and wired to a 3 pin plug and cord. Next i had to design and build a mount for the motor as that was missing however when i tried to fit the motor in the stand it was obvious the belts were too short. So disassemble the bearing buy and fit two new longer belts and reassemble the arbour. The motor mount was fabricated but i had mounted it a little too low but a nice set of machinery feet solved that problem. i ordered an emergency on off switch and wired that up in the original hole but it sticks out a little. I bought a new wire and grinding wheel fitted and tested the build so far, it worked fine. It seems that when this grinder was made that end shields and eye shields were not required so i had to fabricate them. This required me to use the plasma cutter and MIG to cut and fit them. The eye shields fell off a display stand and they work well as your hands fit in the Great Australian Bight. The last hurdle was to weld the cast iron tool rest back together. It has been 40 years since i last welded cast iron, not a lot of cast iron on the helicopters i worked on. I practiced on a broken vice and when i felt brave enough i welded the tool rest back together. It is not perfect so i painted it black to hide it. It now stands finished in my welding bay. Regards Steve

Great save!
My favourite type of grinder- big! A bit easier to use when you just have to lean your body-weight on the job, into the wheel.
Probably super sell-able, now it has a 240v motor.
