Neither a pilot or a sailor. By day, I create computer models that are used to automate repetitive tasks. Years ago, someone gave my that nickname.

Additional note. I've used regular white glue for years and that's what Rob suggests. On another sit I found a recommendation for Aleene's® Quick Dry Tacky Glue™. It not only dries faster, but

Sorry I'm so slow with this reply Jim. You have shared some wonderful tips and techniques. I have already cleaned out nail polish bottle and filled it with glue! So clean and precise! Thanks so much,

Hi Jim... Good job. Thanks for sharing. Your project reinforces my desire to acquire a 3D printer. Now...looking forward to seeing what you do next. Cheers from San Diego. -Jim Coffee- ps: Why

The most challenging thing is that the long gear rack binds at both ends when moving slowly. Perhaps a slow gear motor is needed. Currently, I can’t hand crank it slow enough.

After plenty of trial and error I have a working prototype. To get it right, I had to fiddle with the design and print a few parts more than once.

Good job... Keep going! -Jim-

I am not familiar with those settings. I adjusted the design instead. Thanks for the suggestion. I will check it out.

I was initially concerned that the file format would not allow for adjustments. However I was able to alter the individual pieces as needed. Example: I made the rack 0.2 mm thinner in 2 directions. I

I've found that PLA is not the greatest with close tolerances and the design needs to be fiddled with a bit to get it right. In cura you can increase/decrease the size of the design quite

Hi Jim... So I think that I understand that you are able to load the file up into Fusion360. Keep in mind that I'm a neophyte with both Fusion360 and Cura. I just did a bit of poking around and find

Hi Gus... It's absolutely OK. That's what this forum is all about. Cheers -Jim-

Thanks Jim for those answers ! Since I have already decided to motorise the Politician, I will be asking you for other information as this proceeds, hope this is ok by you. Regards, Gus Keep Safe

It's supposed to look like this... but I can't get any of the interlocking parts to fit together, despite considerable sanding and filing. The tolerances in the original design are just not set up for

Thanks! I am often amused by combining two seemingly different things.

for starters, I am attempting to construct it as is. Once I figure it out, I will adapt it for other use as part of another project. Currently, the file is giving me fits! This has happened a

Good morning Gus... Yes, you are correct. The slip-ring is to avoid twisting cables. The reason that I've got ten leads is that I ordered three slip rings with 10 leads. You are correct...I only

Hi Jim, Are you constructing an automaton, or the mechanism as in the animation ? Gus

Hi Jim, The slip ring seems to be a method to transfer current to a rotating element, overcoming the twisting of the cables, is that so ? Ten cables go to the motor ? So many leads, merely for

I'm getting the Peddler assembled. There was a conversation recently about slip-rings. In the 1st image (lower center of the image) is a slip-ring assembly. First, let me explain what I am
