    FREE! 3d Printed Parts and FREE! Wide Radius Curves+Wheels

    Same here. Even though I am fully-proficient in CAD and have a printer, I do not want to make track pieces or other elements where a small-scale manufacturer has a viable product available. It’s not just worth it if you care about where you use your time and about the quality of the product.

    FREE! 3d Printed Parts and FREE! Wide Radius Curves+Wheels

    Indeed, I have bought Tamiya spray paints and I will use them to achieve DBG and Black surface coats. Regarding the color of the resin, the issue is mainly that e.g. green and black behave quite differently when printing. I have figured out that with Anycubic black, you can achieve very tight fit between parts by offsetting with 0.15 mm. With green, that figure must be at around 0.25-0.3 mm. The vertical tolerances are more complex. You just need to experiment to get everything right. At the moment, most of my parts come out right from the machine without any or with very little post-processing. I am indeed trying printing connecting rods with The SLA. I’m experimenting with the UP Challenger’s 1:48 scale versions. They have integrated ball bearings. The ball bearings should distribute the load quite evenly and the rods are reasonably stiff anyways. I don’t see why this wouldn’t work. I have steel axles and ball bearings everywhere so the setup is very tight. It shouldn't vibrate at all, which reduces the stress on the rods.

    FREE! 3d Printed Parts and FREE! Wide Radius Curves+Wheels

    Hi, I have been 3D printing parts with my SLA printer for a while. E.g. wheels and connecting rods. You see images on my Flickr account below. However, I do not intend to reduce the usage of Bricktracks and BrickTrainDepot and other manufacturers for the following reasons: (1) It takes a lot of effort to get the manufacturing tolerances exactly right so that the parts clutch together. Eg with SLA, it’s down to the color of the resin which offset value you need to use (2) SLA printers use resin which is brittle and not as strong as ABS plastic that the commercial printing services have (3) Designing a part is a lot of work to get exactly right from design and functional aspects. I do respect and value the quality of the design work that’s been put into the available products from BT and BTD etc. and I want to support the businesses as they keep this hobby developing.

    Trixbrix slip switches

    Thanks - this will be useful!

    Bluebrick Layout Software

    Indeed, this is a smart move. Thanks a lot.

    Bluebrick Layout Software

    Hi, I just started using the software. Good first impression, I got stuff done with almost non-absent learning curve. However, how do you draw Lego Grand Curves? Those wide radius curves using only straights?

    Just discovered that Lego trains are beyond my reach

    Do the following: - select stores arbitrarily - create carts - open the carts, and review the parts and their prices individually After the analysis, you may find some ridiculously expensive parts. Eliminate them and repeat the cycle above. If there are some expensive but unavoidable parts that you want to have, better strategy might be to buy them separately from stores selling them only at good prices, and get the remaining parts though BrickLink’s automated buying. As said, a target price for a large, 1:48 scale steam engine’s parts of high quality should be $250-300. I think I paid that much recently for Union Pacific Challenger with mostly new conditioned visible parts.

    I’d do exactly that. Your bill of materials is 2x what it based on my experience (4 steam locomotives with BrickLink parts) should cost. Go through the parts list manually. It might also be that the rare/expensive parts have such limited supply that you end up paying premium from all other parts as well!

    Lego Train Suspension

    Very interesting, good job! I also would have wanted to have suspension in my Big Boy and Challenger, but could figure it out. It would have limited both engines to two XL engines at max, and/or had limited structural rigidity. Have you would a way install the boiler panels yet? The Big Boys boiler diameter is 107 inches or 7.1 studs in 1:48.

    Totally new to this

    It’s good to be aware of the costs. The bill of materials for the Challenger comes at: - parts 280 EUR (I live in Europe as well and use the German, Polish, Hungarian etc BrickLink stores a lot) - motors (3 x XL) ~50 EUR - FX Brick controller, lights and speaker ~120 EUR - wheels (I’m using 3D printed which are expensive) 50++ EUR - the pushrods are valvegear on top - stickers If you choose to build an 8-stud wide 1:48 scale big locomotive, it will cost you. With the plan, you also get the stickers so I consider it indeed good value for money.

    Hi, another easy way to get started is to buy a plan from BrickTrainDepot.com. You can get the instructions in pdf and xml-file of the required parts that’s easy to upload to BrickLink where you can purchase the parts. If you are uncertain, I’m happy to help. After inspecting plans from great designers, you can soon start making your own designs. I’m indeed constructing my own Union Pacific Challenger on “Month 11” in the LEGO hobby. So you can make the learning curve pretty fast by inspecting and adapting. The LEGO train community is also very helpful and approachable

    Best place to buy MOC trains?

    I don’t see BrickTrainDepot.com been suggested. It’s an obvious pick for high-quality plans. Recommend.

    MOC: Big Boy X4023

    Sounds great! Your next challenge will be to transfer all that torque to the driving wheels without breaking the gears or dislocating any driveline component.

    MOC: Big Boy X4023

    You will be traction-limited with your Big Boy; the engine is somewhat prone to gear slippage under heavy load. Therefore, even distribution of power to two sets of drivers is better.

    MOC: Big Boy X4023

    Please notice that the motors don’t necessarily have to be placed where the power output from the engine is. It is possible to have the motors placed in more convenient locations of your choice and output the power elsewhere. See picture below. However, this limits the number of motors you can pack into the boiler and works better with L motors which are 4 studs wide (XL is 5).
