Tell you clearly: no! Unless someone does the same thing as you, if you want to see your problem, you should send your own design as a document. The fixture design of online valve rocker arm shaft bracket is all boring fixtures with 20 holes (in fact, boring machines should be used for more than 30 holes). Decent design is copying the graduation thesis of a guy from Zhejiang University. I reward 100 points, and no one can answer. If you want to drill 20 holes, you can borrow them from me. It is better to rely on others than on yourself. It's also very fast to find a teacher to check the information (in fact, I still have many questions = =! I can't help it I will hand in the photos soon. At least it's almost finished now, alas ... I'm going to wash and sleep. By the way, I despise the brush marks on the convex surface (doesn't it count that I type so many words = =? )
