Hard to make up my mind... either Pink Floyd Dark Side of the Moon, Zeplin's first tour with Jethro Tull opening 69, but probably Crosby Stills and Nash with Joni Mitchel opening in 69.

Les' comment brings us back to the question expressed in another thread about "Why rubber tires and not cast resin." For me it is an esthetic choice going back to my youth and the models of the 60s. But this is another subject.

The one advantage that I see in the relm of 3D printing for the high end builders would be in the tooling of more accurate tires. Mr. Wingrove's process already requires several steps to tool the hard resin final mold and the level of detail will be much more accurate. I had considered scanning the old tire ash trays that were a marketing tool and abundant in many service stations here in the states back in the day. They appear to be 1:6 scale but have all the tread and sidewall details of full size tires. Thank you Noel for another thought provoking discussion.

I stand corrected, and rightly so. I lost my focus on the title of this thread (My wife calls it ‘playing the Devils idiot’) and I did not mean to minimize the skills, abilities, and pure dedication involved in hand fabrication of models. I am also a great fan of Mr. Wingrove and am inspired by his books on model building, and deeply respect the work of those who are so gifted. I hope only to aspire to a fraction of that ideal. So I grant you then that 3D printing is simply the act of producing kit parts from which we can build our models. I will however contend that the drafting aspect is still much more involved that just doing layout work. The 3D work we do in ‘Model Space’ and still contend are solid forms, can be used to provide dimensioned layout sheets as would be used for hand fabrication. However, we now have the technology available to have our models milled or print as a kit in any scale. 1:1500 through 1500:1 (as an example.) To date my only 3D printed kit has been in collaboration with Mad Mike on the 1965 Indy DOHC Ford, and yes we did digitally drill every hole for the bolts and linkage. Mike even went as far as to create all the hose fittings, linkage, bolts, nuts, and hex socket cap screws, some with holes for safety wire. The dilemma is that in order for Mike to print the model in 1:24/25 or even 1:43 he had to go back and fill all the holes and fuse/union all the nuts and bolts, etc. to the larger units. For the sake of argument then can we also say that any machine work which involves the digital programing of mills, lathes, and routers would take those operations out from under the heading of scratch building?

Thanks for your kind words. The miller is a Chris Etzel resin kit which had a assortment of metal castings and photo etched parts. He also used Top Queen/Willis Finecast wheels and tires for several of his kits. Yes, this is one of my favorite color schemes.

Or my modified Brum customized Bugatti type 57.

Any of my Etzel kits, especially the Miller Indy winner.

As I see it, the basis of our hobby is to create scale representations of our favorite, historic, or fantasy vehicles. To that end we use a vast variety of tools and materials to realize that vision. The selection is nearly limitless in scope, paper to plastics to metal. I think that most of us started off in our youth with commercial kits as a basis for our building and progressed to more sophisticated construction and detailing methods as our dedication to the hobby grew. CAD drafting and its associated 3D printing are just a couple of the newest tools and materials to become available to us. To those who believe that CAD drawing is “Just putting parts together” really have no concept of the amount of work that goes into our drawings. The CAD detailer creates every nut, bolt, screw, and complex shapes as 3D solids and surfaces within the CAD program. Just like any other discipline within the hobby, once the parts are shaped and ready for assembly we are all just putting together our kits be they machined metal, cast in resin, or printed in a plastic medium. Going beyond the basic assembly of our kits, all the detailing and finishing is Scratch building. Model On

Song Bird was Sky King's airplane's name.

Nah, that's the wood grain showing through. As Peter said, it was great to se how the 1:1 Sears Motor Buggy was designed and built. Something that most of us would never imagine, you captured so well. I especially like the tie down straps for when the top was down. If you don't mind, what CAD program are you using? Nice organic shapes to the top and the dimond tuck seat is deelightful . Thanks again for a fun ride.

As memory serves, most all British cars, until recently, ran on 6V systems. So it would make sense for Bentley to use two 6's to get their 12V.

Disguise your 1500HP 917 mill in the back of a lowly VW Ghia.

6 volt no doubt.

Morning has broken is one song but do wa diddy was by Leon Redbone.

Love It! Knockoffs and hubs with threads and all.

Are the Webers an linkage stock kit parts? The carbs look to be cast metal. ?

Fantasy is what modeling is all about, realizing your fondest dreams in scale.

Cool! Does it have any affect on the fragility (it's Italian you know) of the older decal sheets? +-?

interesting idea with the sun bleaching. Keep an eye on your reds they tend to bleach out faster than the other colors.

Thanks Ken, you confirmed my thoughts about the speed control and reverse action. If the center of the flywheel were dished a little you could achieve a true neutral with no additional wear on the friction wheel. Very cool, thanks again for taking us through this project.

Hi Ken, going back to your third reference pic I see now how the transmission of power gets transferred to the drive axle. It is the friction drive between the engine flywheel and the small spoked friction wheel. No gearbox required. Dash It All!

Outstanding, can't wait to see the transaxle/gearbox.

great work on the drive line and chains! Scale roller link chain can also be had at MFH and Micro-Mark railroad accessories. Not everyone wants to invest their time and big bucks in machining equipment just to join the "Real" world.

Fantastic eye for detail Ken, and skilled draftsmanship. Love the break mechanism, springs are bear in CAD. Thanks for sharing your project with us, looking forward to getting color on this cutie.

Son, you're gon'a drive me to drink'n if you don't stop driving that Hot... Rod... Lincoln!
