So with our 3d makerspace open I'll post a long-term project where I try to model a very special and kind of rare tractor. This is me trying to get to grips with freeform modelling and sharing my findings along the way. All pictures will be loaded to this gallery: https://www.behance.net/gallery/101740501/Developing-a-Bungartz-T7-Model-for-3d-printing Subject: A very small oldtimer Tractor of German origin, originally made by Bungartz & Peschke, this particular one was probably built in 1965. I'll try to model the T7 variant, which I have direct access to as my father owns one. These tractors are pretty rare, despite being exported all over europe and even US models available. It is believed only 2800 Bungartz tractors were made, including all models and markets. All Bungartz models are very small, some offerings made to be small enough to pass simple barn doors by having a width of as little as 0,7m! The tractors were intended and usually used in wineyards and on steeper fields. They also were marketed for use in greenhouses. For these purposes the tractors have some special features that are worth noting: adjustable track width of the rear wheels via fixed axle adaptors or even via adjustable adaptors as special option. This allows for very narrow width were needed and for trespassing along a steep hill by pulling out the lower wheel to prevent tipping over. 90° steering angle (!!!). This allows for a very small turning radius, ideal for indoor jobs in greenhouses and the likes. individual manual brakes for the rear wheels to assist turning on steep hills and allowing the inner wheel to stand still while turning the tractor around it! This is quite a sight. I have copies of the user manual and spares catalogue for the tractor and for its engine, a Hatz Diesel AKD 10 Z. Our example has a fixed axle and is 0,9m wide, which should be standard for the T7. Here's a teaser of how small this tractor is. To the left is an already small Porsche Junior Diesel, but the bicycle puts it really to scale: Tools Fusion360 will be my main tool. I want to get to grips with it and especially the sculpting environment. Blender may see some use. Maybe I will try doing parts in both, to see what I get the most of. Intention I plan to build a full 1:24 model of this tractor over time. This is the long-term goal. The main goal is to learn freeform modelling and combining of software with the intent of doing a complex model instead of parts only. This is not a real tutorial, as I may go wrong at any given point, lose interest or hit a wall. But I encourage everyone interested to follow along to learn as well and share their knowledge and ideas. Please shout at me if you see me doing something stupid. I might have an advantage regarding strictly regular geometric patterns, but with freeform modelling there may very well be some of you around here knowing far more than I do. I plan to do a full 3d model of the tractor in 1:1 scale, no matter how the parts are produced later. Most parts should be 3d printable in the end. I will offer to print these on demand, should I succeed. I don't expect too much interest, knowing this is a very nieche corner of our hobby. I plan to do a 1:87 (H0) print as a gift for my dad to add to his model railway layout. The first steps have already been made. I'll share these in the following posts along with more pictures.
