Recumbent Tike – Improvements II

If you let an engineer build something and use it, it will get tweaked over time. Now that the new seat is on the trike and I have been riding more, there are some more changes to make: Rear fender Headlight and mount Cyclemeter for my phone and Apple watch along with speed and cadence […]

Ring Roller Dies for forming a curved V shape

For the Path Light project I needed to make curved corner pieces for the roof. The roof panels are roughly triangular and the corners have a roughly 1/4×1/4 angle of “12 oz” copper to cover the corner. The twist is that the roof panels are not straight but instead somewhat concave giving the roof a […]

D-Bot – 3D printer upgrades

About 2 years ago I built the D-Bot  which is a core-xy style 3d printer. What this means is I have a printer with a relatively large build volume of roughly 300mm^3 and a fairly rigid mechanical structure.  My efforts on this design can be seen starting at: http://bronkalla.com/blog/2017/03/12/new-3d-printer-project/ To the basic printer design, I made […]

Isla in her crib

So now the project is complete. The crib is delivered and Isla seems to enjoy it. However at 3 weeks old, she still seems almost lost in it.

Crib – Mattress frame

The mattress needs to be height adjustable. With this design there are 3 heights available. High, low and floor. The frame is made of 3/4×3/4 ” 14 gauge steel tubing. It is sized to fit about 3/4″ inside of the wood frame. The frame is supported at the corners, however the screw and nut locations […]

3D Printing Nylon

One of my goals when building the printer was to be able to print nylon and other high temp materials. For the trike, I wanted to print some parts for the chain idlers in nylon. So I ordered some Taulman Bridge nylon filament in Black.  This is supposed to be one of the easier nylon […]

Recumbent trike – idlers and longer ride

The trike is now mostly done, but the drive train was giving me grief. The idlers were not working out and I replaced the rear cassette due to the chain skipping.  The previous owner of the components had beat the bike more than I initially thought with damage to the cassette and outer crank chain […]

3D printer Improvements – Bed leveling and Thermocouple Amp

3 point bed leveling was needed. I really should have done this from the beginning. 4 point is way too hard to do and results in warped plates. 3 point gives nice control and no warping problems. The right side of the heated bed has the single screw. I now have it set up with […]

3D Printing parts for the Printer

At this point the printer isl making more parts for itself. Teal (my wife) compared it to Frankenstein adding his own parts after he had an arm attached. One of the first part sets was to make a case and mount for the display. The case turned out quite well, but the design of the […]

3D Printer is Running!

The printer is now running It is roughly assembled (as you can see) and now it is time for fine tuning and making parts for itself. I love it when a tool is at the state where it can help finish its own build or rebuild making parts. Cases for the boards, cable retainers, cable […]
