Elmer's 36 Reversing Wobbler - 2x - Imperial - Mike's 2nd engine
mikehinz:
Wellll, here's my start on my 2nd engine! It's a Elmer's 36 Reversing Oscillator at 2x from the original scale and done in all imperial measure. I selected this as I thought it represented a reasonable next step to further my machining technique. Plus I wanted to really learn Fusion 360 and this gave me a good reason to do so. The original drawings are not that clear in certain respects and I wanted to scale it up without making a bunch of mistakes while cutting metal. So, over the last couple of months I've been slowly drawing the engine, making lots of mistakes, and redrawing numerous times, but I think I've gotten something close finally.
To start this, you'll note some raw stock with an engine hidden in there somewhere! Also, I've attached a few renderings and screenshots that i did in Fusion, just to prove that i actually drew it! Finally, I've attached a single 2D drawing of one of the first components that I'll build, that being the base. My thinking is that I'd upload 2d drawings as I go along so you can see what I'm attempting to make and then have some pix of the actual machining process of whatever part(s) I'm working on. Does that sound reasonable and interesting enough?
Also, I do have one issue in the Fusion model. I've managed to make a joint between the cylinder and the column and rotate it so as to prove the air passages all matched and the rotation angle was correct, but so far, I've NOT managed to animate the entire engine. The failing is my current lack of understanding of joints and animation within Fusion. I'll be working on that as I go. I'm kind of certain that I've got everything correct so that the engine will run, but there could be some small dimensional error that would prevent that from happening. I'd LOVE to run this engine virtually and hopefully I will soon!
Any suggestions or comments on this project are greatly appreciated!
Thanks. Mike

I'll be interested in how you get along with Fusion 360 and animation.
An area I'm particularly interested in is animating cams.

Carl, I'll certainly keep this thread updated with any successes or more likely failures, with Fusion 360. I'd done various 2D CAD projects over the years and I must say that 3D is/was very hard for me to grasp, but now that i can do at least the basics, I fully understand why the industry has transited almost entirely to 3D. I find that now I scrap very little as my mistakes are now much more 'virtual' than they used to be.
Later this afternoon, I hope to get some of the stock cut to basic size and to start taking to exact size on the mill. Even more hopefully I hope to remember to take a few pix of the process!
Mike.

Already off to a great start Mike and the drawings look good too!! More importantly, you already understand the basic rule here...if there ain't a picture of it, it didn't happen :lolb:
