The wood fixture was only used for the finishing pass and engraving for the top. The rest was just held in the billet by leaving a .020" layer around all sides.
Damn that’s pretty smart! I used to work P&D in the aerospace industry mostly designing tooling and working out new programs in vericut. I like your approach! Nice work!
@KingJalopy@lemm.ee thanks. The fixture wasn’t initially planned for, but the last pass on the roughing cut for the front went too deep and thinned the tabs holding it in the billet a little too much for comfort. So I just used the cad file to make a negative that I cut into the wood. The Scaling Banana™ fits quite snuggly into the fixture, the grey silicone was just to keep it from lifting out during machining.
I didn’t even consider tabs when I first looked at it. We were discouraged from doing that at my job simply because too many button pushers worked there and could easily mess stuff up lol. We generally had them only roughing and the finish was always an actually machinist lol.
@KingJalopy@lemm.ee I’m not an actual machinist, just self taught. Also my machine isn’t particularly nice/precise. It’s an 90s bridgeport with a 3 axis cnc kit. So I try and use whatever tricks I can to make it all work out.
Bro rocking a bridgeport makes you more of a real machinist than most people lol there is no shame in that there is a ton of skill in being able to make stuff like that with nothing more than a Bridgeport.
