So, I’m not sure I’m really much of a machinist with never having run a CNC, mill or lathe. I do have a couple basic machinist and blacksmithing books though and I have a grasp of the basics to a minor degree.
That said, I have a problem that I think can be solved with a push broach or whatever you want to call it. I bought a replacement stump jumper for my brush hog awhile back and it doesn’t exactly fit. It has tapered groves for splines on the shaft to fit in like this \_/ and the problem is they are too narrow. A family friend took it to two of the machinists he knows and neither was able to solve the problem. I don’t see why one couldn’t fashion a push broach and holder and just scrape the grooves wider one at a time. There’s 12 grooves to widen and I want to say it’s a 1.25” hole in the middle of them.
I’ve never attempted anything like this however, so I’m looking for some input, otherwise I’m just going to take my best guess based on my limited knowledge and hope for the best.
