Wow ,You make it look so easy. How long did it take to design the pattern using Alibre and then to convert it into a machining program?Jo
Fantastic pattern, Steve, and it looks to have a superb finish. Is shrinkage allowance built in, and is there a draw taper there as well? I'm not familiar with the engine, is there a link to find out more?Cheers, Hugh.
What tooling do you use to cut it, (HSS or carbide), and what feed/speed would you use to cut it. I want to set it up as a material in BobCad.
The finishing pass with a 1/16 bit must have taken a loooong time! It looks great, I will have to investigate this Ren board material.Lee
Steve,First off, it was good to talk to you in Zanesville in October. Maybe you remember.Some time ago, I bought the casting for the Deezil form Roger Schroeder. I started the build, and somewhere in the process, I ruined the casting. Since I had already accumulated some stock, and worked out procedures, and made some fixturing, I intended to get another casting and give it another try in the future. Sadly, in the meantime Roger Schroeder passed away.Anyway, good and interesting work on the patterns.--Tim
Thanks for that link, Steve, a thoroughly entertaining history of two terrible engines! I'm sure yours will will not carry on the weak genes of the line.I'm assuming that the patterns are for sand casting - are cores involved? I can't see any core prints there, although the runners are very well sized.Cheers, Hugh.
