Took me a bit longer than I anticipated, but I have a pretty good excuse for being slower than most on things. LOL! Seriously, it was so much fun. KenH & I were talking, as we both love building things. He has been a trusted source to bounce ideas from when I was second guessing. Thanks Ken!
Materials in. Used a combination of 1018 cold roll, and billet aluminum, most of which being 2024-t3(my favorite flavor).
I designed this with plans in my minds eye. This was the start. It's a cast iron housing from an old HF 4x36, if you can believe it. I am a pack rat, as most home builders are, and NEVER throw out big chunks of iron, steel......pretty much anything! I then drilled 5 inline holes and mounted this 7/8"x5"x12" 1018 steel plate. I wanted the grinder to have a solid base with considerable mass!
My mini mill was invaluable throughout this build! Before I had the mill, I was planning a build with tube steel. And nothing wrong with that. They are great! But having the ability to machine steel & aluminum billet bar stock takes things to the next level.
And of course keeping my fluids up with all this "hard work"! Keeping a supply of Yuengling Lager- America's oldest, (and best) brewery. I am sorry to those left wanting of the pleasure. LOL!
I spent time really designing in the small details of this build. I used roller & thrust bearings in the tension arm riser pivot .
And the tracking assembly I am very proud of. Uses both the standard hinge adjustment, and also the slotted attachment point, to "cant" the wheel.
I also went with a 12" platen. Don't really see the need, as I have my surface grinder, but I figured "why not?". Eventually I will also have a more compact platen.
Lastly, I debated with motor placement. Originally, I planned to use a hardwood board to bolt the grinder to, with the motor bolted down behind, but at the same surface level. Towards the end of the build, I realized I could utilize a plate bolted to the back of the cast iron base(to provide a level surface, square to the assembly).
And now I have a grinder to be proud of! It came out exactly as I wanted, & I could not be more pleased.
And with the contact wheel & SGA ready to go. You can also see my trick 45 degree attachment for the contact wheel.
Oh yeah, the motor is a 1.5hp Dayton & it is run on a Lapond VFD. Also, some might wonder why I didn't make it horizontal. Because I did not want it to be. I converted my 1x30 to a 1x42 horizontal/vertical. And I don't run the SGA horizontal because I prefer it at the 45 degree. I wanted this grinder to be solid! Look close; the 45 degree was carefully designed to work with the SGA-SPECIFICALLY!
And here is a crappy video. Was simply attempting to show how smooth & quiet this thing runs. And man does it ever! Purrs like a kitten... But can also ROAR like a lion!!
