The test track is one of my 3x9 tabletops, with the left hand end 10cm or 8cm above the right hand end. The best ball bearings I have meet German standard DIN 620 precision rating P0 which is equivalent to ABEC 1.

Make the cars heavy enough to prevent stringlining and the magnetic couplers will pull apart, strengthen the coupling and you go back to strignlining. I have that but I need a really steep ramp to get the wagons through the last horizontal section so I've dropped back to 3 sections one way, 6 sections back, then 3 more to go straight down the ramp. The use of 3D printers makes it possible to produce LEGO compatible components in smaller quantities and without the need for complex and very expensive injection molds. To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average.

We design and 3D print LEGO compatible wheels and LEGO compatible rods to help further the LEGO train hobby. The photos of the scales have had the display area curves blown out so you can actually read the display in the video.

These wheels were connected to a modified 2x4 brick and their running characteristics are much worse then the 9V train wheels. Part 2878c02 has a metal axle that does not, and the wheels are easily removed from the axle after being removed from the housing.I can't find an existing thread, so while we can still sort of get the older metal axles I thought I should make sure the new ones really are improved. Here is a short video showing construction of a four wheel tank engine using all LEGO power function parts (motor, battery and IR receiver) and four medium wheels with o-rings. They built up a track with only curved tracks used and run the same train from the same battery, only with the wheels differing. At that time I found only the solution using modified train wheel holders from Legopold https://www. One bearing arrived in pieces, and just generally the Lego axles+wheels I have don't stick together very well so picking up a model generally means half the wheels fall off.

Before Ben Fleskes started to produce his BBB train wheels, this was the only and very expensive method to add some more steam engine realism to LEGO train models. If you use a self build Power Functions drive train you can power your locomotives right throught these train wheels. The wheel holder is mainly available in black but was also produced in grey and light bluish grey for some sets. The site is aimed at RC hobbyists but they'll happily sell bearings to anybody with a valid credit card.It makes testing rolling resistance very tedious as I have to find all the wheels and washers then reassemble the test vehicle after every test.
