Crow T. Robot / Re: Crow has a problem. Down there.
« on: November 03, 2015, 12:14:30 PM »
Thanks, Ron--that thread and have been helpful, but I still feel like this area could be covered in more detail. It's funny, as there are some very exhaustive, detailed pics of Crow's many different parts (neck, shoulders, pin, etc.), and how other members have done them. But his "business end"--arguably one of his most important and technically involved aspects--has so little. It's possible (probably, even) that I'm just being obtuse, but if anyone could share even a diagram (cross-section?), that would be great.

And what are the variations everyone has done? Does everyone use one hand to work the mouth and the other to turn head/move eyes? Are there other ways? Some of the pics on the site are helpful, though a few are intriguing/baffling (see attachments).

Come one, gang--let's shine a light on Crow', area.

Crow T. Robot / Crow has a problem. Down there.

I feel like I have a pretty good handle on Crow's eye mechanism in his head, but I wonder if you all could share pictures, diagrams, concepts, etc. for how it all comes together...down there.

I'm wondering about specifics--how much pipe below the bottom Floralier? How does the "popsicle stick" mechanism work? Where exactly did you put it, and what's it made from? And, well...just about anything you'd care to pass on.

I'm very close to finishing my Art--this is really the last major hurdle. Share with me, won't you?

Hi Ron, I know it's a very old post, but is there a chance you could reload the pictures you posted on the first page of this thread? Many of them have gone away. I would especially love to see anything you have regarding connecting the grabby hand to the "guitar pick" wrist joint. Thanks!

Finally was able to get the remaining parts necessary to finish my Art--woohoo! But I'm wondering how the cylindrical wrist-end of the grabby hand is connected to the "guitar pick" wrist joint. I'm guessing drilling through the cylinder is involved, but haven't seen this specified anywhere. How did you all do it? (High-res pix greatly appreciated)...   :)

I figured out my problem--the leather I initially used as a hinge was really thin (maybe 1mm, if that). I got a MUCH thicker piece of leather (maybe 3mm), and now that jaw goes nowhere but up & down.

Intriguing--I can't quite visualize what you did, though. Which part of the plastic base, and where did you screw it in place, exactly? Could you post pictures? I will try to do the same for mine, sometime this weekend. Thanks!

I'm okay with being a little bit off--as you say, it is "100% screen-accurate." But mine is ridiculous. I'll check the placement of the elastic cord, to see if it's perfectly centered. Any other tips to keep that jaw non-wonky?

I'm having trouble keeping Crow's jaw in a stable, up-and-down path. I'm using the leather hinge and elastic cord looped through two small holes in the "e" and two small holes in the lower pin, knotted on the inside. But when I pull the string to make his mouth open, the lower jaw often goes nutso--left, right, sometimes even tilting a little sideways. It's sheer luck if it manages to go back into place when closed. I'm obviously doing something wrong, but can't see how to fix it. Ideas, hints, suggestions welcome!

Yes, that's the size I've been able to find. So the "1/4" is a typo, then, and should be "1/2"...?

Thanks Ron! I will probably be going with a "Bob Stand" down the road a bit.

I also had a question about the section between the floralier and the bowling pin--elsewhere you posted a picture of the whole assembly, and one of the pieces is described as "3/4" to 1/4" CPVC T with T removed." But for the life of me, I can't find a T that's 3/4" to 1/4" anywhere. Is it possible you meant 3/4" to 1/2"...? If not, where did you find the 3/4" to 1/4" T?

Crow T. Robot / CPVC lengths?

Ron, I've seen your very helpful picture of the various sizes of CPVC used for Crow, and how they fit into each other. But I can't seem to find their lengths anywhere. I figure everyone's mileage may vary slightly from build to build, but a ballpark idea of what I should pick up at the hardware store would be greatly appreciated. I don't want to shell out for way more than I'll need if I can avoid it. Thanks!

For those who have worked with both: besides the desire for accuracy, is there a practical difference between 38mm and 40mm ping-pong balls? (And don't say "Yeah, 2mm," wiseacre). Finding the older 38mm balls is considerably harder & pricier, and I'm just wondering if they're worth the extra time & expense--in other words, does using 40mm balls lead to difficulties in construction with other parts?

P.S. I have a HUGE box of of old fragile 38mm and new 40mm Ping-Pong Balls in case I want to recreate opening Captain Kangaroo skit with Servo and Crow like in episode 403_City Limits

1984gojifan, would you be willing to part with some of those 38mm balls...? :-)

From others' comments, I've come to the conclusion that using an actual Schwarz Bros. soapdish is less than ideal, so I'll be using one of Bob's vacuformed parts (unless I can get a lead on the Elusive Randy of Lil' Monsters (is his last name Denby, I wonder?)...

Bot Building - General Discussion / Randy at Lil' Monsters?
« on: April 17, 2015, 07:35:17 AM »
I keep seeing tantalizing references to "Randy at Lil' Monsters" and the amazing bot parts he makes, but for the life of me I can find any way of locating this fine fellow. Most references are a couple years old, so maybe he's not in the biz anymore, but there are one or two posts that suggest otherwise.

Can anyone point me in the right direction, if in fact Randy is still active in the bot part world?
