A brief,general,overview of assymbly and construction of my AHEG grinder.
I designed and built the first prototype of this grinder about 4 or 5 years ago and have used it extensively in the construction of my knives ever since. This is one of my most valued tools,I would not want to build folding knives without it.
My good friend and fellow knifemaker Paolo Ghio wanted to build his own AHEG,I told him I would help him. This one incorporates some changes to my original design,mainly,a wider apron for the tool rests to sit on and wider tool rests,not to mention a beautiful paint job.
Its going to take a while to post this WIP,I will describe what each series of photos shows and will undoubtedly leave out some pertinent information so,please ask questions!
This grinder has 4 grinding stations,the 4"drive wheel,left and right corners and the flat platen. I use Bader small wheels and used the Bader small wheel holders as my basis of design for my small wheel holders. While the machine is running I can grind three different radiuses and a flat. I can change the small wheels if desired for even more versatility. This is the machine that I grind my bread slicing knife blades on,the serrations and the bevels.
On my first prototype I bought the tracking/tensioning assembly and the drive wheel from Beaumont Metal Works but we had to build this tracking/tensioning assembly because Beaumont is temporarily out of stock. We bought the motor,variable phase converter,and small wheels but built everything else in my and Paolo's shop.
1st photo shows the base plate with all the holes drilled and tapped.
2nd photo shows the variable phase converter being installed. The bracket that it is mounted on is part of the belt guard off of a riding mower.
3rd photo shows the power cord coming through its hole in the base plate.
4th photo shows the motor,sitting on the baseplate before it's installation from the bottom side of the baseplate. This is a C face motor so the mounting bolts go through the base plate and into the face of the motor. The washers provide spacing between the motor face and base plate.
5th photo shows the motor shaft protruding through the base plate and the bolts that hold it in place. That motor is 2 hp 3460 rpm 240 volt 3phase.
