My Harley Knucklehead Design In Plastic

[draw-tech]

Hi all
I Designed this model engine a couple of years ago, This is about a 1/4 scale, working model, made totally from bar stock.

I have started to machine the real motor, but decided to make it in plastic first.

If any machinists out there, you may want to check out my free download of the complete motor.

A very nice looking engine Jack. Doing it in plastic first is a great use of your printer.

Is that all ABS or did you wind up trying one of the exotic filaments?

Hi Eaglezsoar
Yea it fun, but it got me itchy to start machining the real one. I have well over a year in the design of that motor. If you log on to that site, http://www.homemodelenginemachinist.com/forum.php
check out Stephens knucklehead build in work in progress. Give a good idea of it's size. (This guy is good)

Hi IMBoring25

All ABS, waiting for some of the t-glase to come. I want to be able to see inside at all the moving parts, next as soon as i perfect my hot end, polycarbonite !!!!!!
