My apologies for not posting last Monday, unfortunately a loved one was involved in an accident and we didn’t leave the emergency room untill 9pm. All’s well and they’re on the mend so let’s get back to normal.
Last year, coincidently about this time, I shared with you my designs for replacement axles for the HO Bachmann 4-8-4. You can find the post here. This week I’ve updated the 3D printed model to include the main drive gear.
The gear is less likely to split than the axles, but sometimes it does, so a set with everything in makes sense.
All the parts are joined on a 3D printed continuous bar so they’re all one part; this makes them cheaper to print, but the bar doesn’t actually touch the parts so there’s nothing to be cut off or trimmed as with injection molded parts. This is one of the many things which makes 3D printing great.
The parts are also available separately and they can all be found in my Shapeways Shop or via the links below.
This coming weekend, 1st to 3rd March 2019, is the N Trak convention in Bournemouth, England and again it’s at The Trouville Hotel. You can read a bit more about the 2017 convention here and the 2014 convention here. I’ll be there over the weekend if you’re in the area and want to come by and say hello.
