Looks good and some super photo's. The close up of the blade must be the 400 grit wheel? The lines on the blade tip will leave scratches if that's the 1000 grit. I would also break the sharp corners of the blade and make a 20 mm 40 mm radius tooo. That design is a copy of Stefan Gottswinter lapper? Also my friends in Austria have a lapper the designed with a special wheel with 2 diamond surfaces on one side, theirs also has a vacuum too as the powered carbide grit is dangerous.
Yay! I’m on the right track!
Yes, the closeup is 400 grit diamond. The 1000 grit cleans those up better. I knocked my jig together pretty quick; I wasn’t sure if I was barking up the right tree at all. Now that I know I’m in the right neighborhood, I think I’ll do another more careful version with more radii (such as the tighter ones you suggest, more for the finishing stages, right?)
Thanks for the safety tip on the carbide and diamond dust extraction. I did notice later in the evening at bedtime I could taste grinder dust
I will rig up a shop vac dust extractor for my setup and wear a respirator.
Slowly getting better manipulating the scraper. I keep devolving to using my arms, recognizing it when they get tired and my back starts hurting. Trying really hard to use body strokes for this roughing and early phase scraping as described in your videos and the Machine Tool Reconditioning book.
Latest progress below. Still roughing and a bit heavy on the canode blue I think. Working on finding the balance between not printing and over printing.
Thanks for your replies here, it’s extremely motivating to hear from you!
