Rossbotics Angle Dresser

[Tek12h]

Recently, I’ve been looking for a grinding wheel dresser to dress some angles. I’ve came across the ever so popular radius/angle dresser, however that seemed too big for my needs. I did a little google search with some keywords and behold a DIY popped up. I understand this angle dresser is not meant for super accurate angle dressing as the commercially available ones are. I’m totally fine with angle block setup for accuracy, it will be great for what I’m doing. So all the Credit and Thanks goes to Rossbotics, he did all he hard work

This tool was a gem to complete, and is quite the handy little dresser.
I made a few changes to suit my needs. It’s a bit longer and wider, maybe 1/8” wider and about 1.5” longer.
The threads were changed as well, he called for 3/8-16LH threads and I went for 7/16-20LH. Mainly because that’s the Size tap I had that was close as well as I had a die to make it quick.

I used some 4140 for the body, 1018 for the base, pivot brackets, and screw retainer, 303 for the screw and handle knob, and 2024 AL for the knob.

I did not get any pictures of the work on any of the smaller brackets as. They were simple drilling operations, I used stock to size and then cleaned it up on grinder.




Starting work on the upper body portion.




Cutting slot in lower body.




Body complete, testing fit




Lathe work is next, starting on the screw first.





The knob, tapered and threaded. Used a die for 10-24 threads.




Finally the hand wheel. Knurls didn’t turn out too well, should’ve went deeper.





Final assembly before grinding.





Grinding begins!




Final assembly, ready for use.




This was a fun project that will definitely get use in my shop. Thanks for checking it out and Thanks to Rossbotics for the clever idea and sharing it with us!
