Belugawrx Posted June 22, 2018 Posted June 22, 2018 Wow Pico your just whetting our appetite, arent you... Inlaid cherry door rails ..oh my ..hehehe Love watching a good scratch.. Cheers
Jason Sheer Posted June 23, 2018 Posted June 23, 2018 Those seats are looking sharp! Not much ribbing at all in those prints! How is shapeways to deal with since they do a gradual price bump for the materials every so often? Is that the powdered sintered material?
Pico Posted June 23, 2018 Author Posted June 23, 2018 Jason, The powdered sintered material is the strong white flexible material; which is a low resolution material and it's very "layered". It is not suited for detailed items, I have used it on bodies, but I don't use it now because of the difficulty of finishing it . I now use a local 3d printer to make my bodies - see my " The supersonic has landed" discussion thread. The material used in the door panels and seat is Shapeway's smooth detailed material. The cost of those items is $32.80. It has very little layering and is easily sanded to a smooth finish.
Jason Sheer Posted June 24, 2018 Posted June 24, 2018 Pico, Thanks for letting me know about the shapeways process. Again, excellent build and looking forward to seeing the rest of the pieces in this puzzle!
Pico Posted July 16, 2018 Author Posted July 16, 2018 Because the windshield frame is so thin, I've decided to cast it in white metal. Mastering proved to be difficult, plastic was too floppy, brass did not work well, so I decided to use Ave's Apoxy Sclupt, an epxoy putty. Covered the cowl area with thin plastic so the material wouldn't stick and put a glob on. It's very slow setting at room temperature, about 6 hours, so I put it in a dehydrator. Usually takes 45 minutes there. Sanded it to shape and detailed with half rounds and small turned knobs. I did not cut all the way through, to retain strength. That will be done in the metal.
Pico Posted August 11, 2018 Author Posted August 11, 2018 It has taken several weeks to make the centrifugal caster and molds but it has worked well. This is britannia metal, a lead free white metal that I cast in a silicon mold material called Mold Max 60; that will withstand temperatures up to 560 degrees. I pour the metal about 400 degrees.
Pico Posted August 11, 2018 Author Posted August 11, 2018 A decent result. I'll solder brass rods to the windshield frame to glue into the body.
Spex84 Posted August 12, 2018 Posted August 12, 2018 Fantastic stuff! I'm impressed by the windshield frame, it really sets off the curves of the car. Watching this project progress has been very inspirational.
ismaelg Posted August 12, 2018 Posted August 12, 2018 Gorgeous! I see the benefit of doing it in metal. That piece in resin would be too fragile. And besides, it looks beautiful!
Pico Posted August 12, 2018 Author Posted August 12, 2018 I took photos of the centrifugal caster as I was making it and will post a tutorial about it in the "general" discussion soon.
Gramps46 Posted August 12, 2018 Posted August 12, 2018 Beautiful work Pico. I am looking forward to the tutorial. Gary
Spex84 Posted August 12, 2018 Posted August 12, 2018 Brilliant. I'm looking forward to seeing more details on the centrifugal caster, too. I was going to ask about it, then thought "nah, I'll just google it" but it would help to see exactly how you achieved these impressive results!
Pico Posted August 12, 2018 Author Posted August 12, 2018 I have added a tutorial " Building and using a centrifugal caster" in the general section.
Pico Posted August 26, 2018 Author Posted August 26, 2018 Work continues. I have put a wad of Ave's Apoxy on the model, let it set and am carving it to be a top cover. 3d printed seat and interior door panels are in place.
Gramps46 Posted August 26, 2018 Posted August 26, 2018 Looking real good Pico, keep the photos coming please.
Pico Posted August 26, 2018 Author Posted August 26, 2018 I might be able to finish this thing some day...
shaunmza Posted August 31, 2018 Posted August 31, 2018 This is not a subject I would normally be interested in but your skill and mixture of techniques amazes me to no end. Manually forming and shaping with 3d printing and brass, even casting metal. Thanks for sharing your build process!
mecklm Posted August 31, 2018 Posted August 31, 2018 I don't remember seeing anyone ask yet, so, is that a Bizzarrini body in the background? Another one you carved out of thin air in your spare time? Looking forward to your build of that one! Oh, as everyone else has commented, it's mesmerizing seeing you create such a homogenous car out of such disparate materials. And you get the fit and proportions just right. Thanks for sharing! Mike
Pico Posted September 25, 2018 Author Posted September 25, 2018 After a several week break and massive workbench top cleaning, I'm at it again. Here carving the transmission hump from epoxy putty.
Italianhorses Posted September 25, 2018 Posted September 25, 2018 Brilliant work. Might be wrong, but looking at the pictures, bottom front of the rear wheel flares/arches, is not quite correct shape. Real car has them slanted going down almost at 45-50 degree angle, yours seem more square-ish.
Pico Posted September 25, 2018 Author Posted September 25, 2018 Each of these cars are a bit different. The car I am modelling is a long wheel base car, because it "flows" better. The shorter wheelbase are tighter and fender shapes are different.
Ace-Garageguy Posted September 25, 2018 Posted September 25, 2018 Stunning craftsmanship in a variety of materials, and impressive tenacity...as always. Beautiful work, sir. I had never noticed the swirly-doodles (that's a highly technical styling term) in the centers of the fenders do not in fact line up with the axle centerlines until I saw the reference photo directly above. Most interesting.
