We live in truly amazing times!
A lot of younger folks take it for granted, but I keep on being amused by how modern technology advances make our lives easier. Not long ago I had a rare wind wing bracket broken on my '39 Fordor. I couldn't find that part anywhere and it was impossible to repair it. A friend told to have it made. I did some investigation and it turned out to be doable and not very expensive. 3D model cost me about $7 and manufacturing of the part - about $60. The most amazing part of this ordeal was that the manufacturer is located 3000 miles from me - I found a site where people post different parts needed to be manufactured (no matter how big or small, what material, quantity etc.) and interested factories, workshops or individuals reply and fulfill the task. My request was answered by an individual living in Siberia, we negotiated, I sent the model files, the part was manufactured, I paid and the part was shipped to me. The quality is very good and I'm completely satisfied.
P.S. I totally agree with Louis CK when he spoke how everything's amazing and nobody's happy. https://youtu.be/kBLkX2VaQs4 |

Re: We live in truly amazing times!
That's pretty cool and a bit of an eye-opener. I never knew that type of service was available.

I would mention the method but don't think it would be useful to you in Russia.

Re: We live in truly amazing times!
A friend of mine is in the specialty electronics field. Occasionally, he will need components for a short run project and puts out international RFQ's and has had components done all over the world.
I really don't know the details, but it seems to be a common practice for specialty manufacturing these days. And, I don't think you have to worry about the language barrier; most of the guys in the business speak excellent English. |

Re: We live in truly amazing times!
I would think the modeling would be the time consuming part, the run time on the machine is somewhat automatic once the file is loaded. If you or a friend can program and/or use CAD/CAM programs it shouldn't be too difficult. If you have to farm it out that might be a cost issue. I built a lot of programs when I was still working for 3D type milling machines, and some of the program files can take a bit of time to build and check out!

Re: We live in truly amazing times!
I am going to look into both sides of this:
1. Having the original handle scanned, to make to create a 3D electronic file. Then the cost of having it 3D printed, with a metal (not sure what is actually available for the printers) stronger than pot metal. 2. The cost of casting a new one (with a better metal), using the original, for the mold. 3. Once the 3D electronic file is created, I could even have one cut (water jet) from a billet of aluminum. Bottom line, is there are a few options available, just a matter of cost. |

Re: We live in truly amazing times!
Several things to keep in mind here.
1. 3D modeling/3D printing is a tool. As with any tool it may be right or wrong to do the job, and you need some level of skill to use it properly, more to get its full potential. 2. 3D modeling and printing DO NOT LIKE COMPOUND curves. The difficulty in mathematically describing a compound curve and the computer power required is amazing. 3. There are some direct printed 3D aluminum printers out there. Strength should be as good or better than most casting. Most of the time 3d printed steel, stainless, or bronze is done by a sintering process by mixing metal powders with a plastic binder, then heating until the copper/bronze is melted and the plastic burned out. Makes nice jewelry but strength will be a HUGE issue. 4. A 3D print done in PLA or wax can be used as the model for investment castings. Compensation for shrinkage can be done at the time of printing. Often with a lot of time savings. Parts with compound curves can be roughed and shrinkage compensated with 3D, then hand finished, and used a pattern for a urethane or silicone rubber mold, then wax poured in for an investment casting. A huge time savings in constructing patterns by hand. I did this with our 1933-34 and 1935-36 trunk hinges and the many door hinge casting we make. 5. For a $0.00 3D modeling software (huge learning curve, poor documentation) consider FREECAD www.freecad.org. |

Re: We live in truly amazing times!
In a/p aircraft mechanics' school, our instructor displayed a complex rocker arm that he was required to fabricate with only a hand hacksaw and files. It was a required project for his pre ww2 schooling. Newc
