Theres always HSS blanks. Get a good grind on them, learned that in trade school. Watch your speed & feed. Carbide seems to work on the higher HP production machines, flooded with coolant. Hobby machines may have a problem pushing carbide, Needs a lighter chip load. What kind of material...

Nice work George! Looks like it came out of a Sears tool catalog! John

Well, not a "W", not castings, or even I.C. Another one of Chucks great "Air Engines". But...it is Green. See these threads: https://www.homemodelenginemachinist.com/threads/john-deere-engine.1720/ Chuck Fellows John Deere engine John

That's an interesting concept. Never seen one of those before. Not familiar with the "Wig wag" engines. Looks like I'm on a short hiatus at the moment, my CAD computer has crashed it's hard drive & spring has come where I will be spending more time outside. I'm exploring alternatives to the...

You really have nothing to lose, & on the "Cheap". Nice thinking! Looks like you have a winner.. john

The greatest architecture, machines, everyday things were conceived on paper. Or burlap, or a piece of bark.. Marks in the dirt.. I still play with my old Dietzgen (Sp?) set of drafting tools. When I was in "tech school" (in the 80's, pre-CAD), I was in the Tool & Die program, drafting...

There has to be a lot of work in those patterns, Good luck with the pour. Though you may not need it, your other castings look pretty darn good. John

I think you're doing just fine Ved, you have some very good skills that only get better as we go. Congratulations to "Grasshopper" & yourself for the build of the "Swashplate" engine. Posted here: https://www.homemodelenginemachinist.com/threads/vedersteins-swashplate-engine-finished.34094/...

Nice job! That looks (& runs) pretty nicely. John

Beautiful castings! It looks like all your time & efforts have been rewarded. Looking forward to this! John

Pretty slick! Never seen a model like that one. John

Welcome aboard! From "just down the road". John

Very nice! John

Here is yet another alternative to a built up flywheel. (I hadn't added the barring holes/slots) This type was mostly used on very large engines I believe.

Hi Jeremy! Welcome to the forum! Nice looking parts you have there! You'll find yourself very welcome here, some really helpful folks. (...They like LOTS of pictures of your projects). Some pretty incredible talent. Don't be afraid to ask questions, it's a GREAT community. John

That's coming along very nicely! Nice work! John

Hello Greg, I think you're doing a pretty good job with all this. I know from my experience, I liked to see only one view of the part as it was presented to the machine spindle, (I.E.=how many operations can be completed in the least amount of set-up's). Make as many pages as you think it takes...

I always enjoy following your posts Ved. Interesting designs for sure, keep 'em coming. & thanks as always for freely sharing your plans (& frustrations). John

Thanks very much for all the info & links in response to my question. I know I can visit the website & see the features & how they say "It's GREAT"...I kind of got a chuckle when I was comparing the versions & between the versions, they were listed as "Excellent, Great, & basic". Compared to...

I apologize if this has been asked before but... Does Alibre allow you to create detailed views? I thought someone mentioned that it can't. Geez.. with old school 2D AutoCad you could create a viewport (remember Model space/Paperspace?) How does it create BOM's? Are they "parametrically"...
