Alasdair Ryan Posted January 24, 2014 Posted January 24, 2014 (edited) My custom driving ring parts are now available to buy on my Bricklink store. --------------------------------------------------------------------------------------------------------------------------------------------------------------------- For my CAD course I had the opportunely to make a project which I choose to make some driving rings which were based on modified lego parts. I am happy to announce that they are now on there way to a 3D printer (nylon). I hope to have them in around 10 days time when I will test them out. If successful I am would be happy to get more made for others how would be interested in a set. Edited February 20, 2014 by Alasdair Ryan Quote
lukeandahalf Posted January 24, 2014 Posted January 24, 2014 Great work Alasdair! Inventor has always appealed to me, but I'm a 2D kinda guy... Autocad is as far as I've gotten. Quote
tibivi Posted January 24, 2014 Posted January 24, 2014 Nice work! Always nice when you can combine your studies with your hobby :p Tibivi Quote

allanp Posted January 24, 2014 Posted January 24, 2014 Looks great. May I suggest that you make the longer, thinner part fit quite snug inside the 16t gear so there isn't any slop? The reason for this is that it will need to be held concentric to the centre shaft as much as possible as you will have a loose fit between the 16t gear and the shaft and a second loose fit between the new inner and outer parts so that they can all rotate independently. Two loose fits will make the outer part pretty wobbly as it is but should still work ok I think. Quote
aol000xw Posted January 24, 2014 Posted January 24, 2014 Nylon is strong and low friction, I am eager to see the results Quote

Jeroen vW Posted January 24, 2014 Posted January 24, 2014 interested pending price I have always loooved custom parts. Quote
Alasdair Ryan Posted January 24, 2014 Author Posted January 24, 2014 (edited) I can tell you the price will be about £10 Uk pounds (inc postage) - 12 Euros? It will be slightly more if you are in the states or another far away place. Very cheep! Edited January 24, 2014 by Alasdair Ryan Quote
TinkerBrick Posted January 24, 2014 Posted January 24, 2014 +1) I would give it a try. Curiously awaiting your testing results (hopefully a small video?). Quote

Could you explain how this works? I'm not getting it just from looking at the pictures. Thanks! Take a look at Jovel's video. Quote
ritztoys Posted January 24, 2014 Posted January 24, 2014 Those parts look very helpful, count me in............ interesting. Quote
Hrafn Posted January 24, 2014 Posted January 24, 2014 (edited) Defiantly. Take a look at Jovel's video. Thanks! Since you didn't mention turntables in your title, I didn't put the two together - I thought you'd somehow found a way to make driving rings for gearboxes that could select between three different gears, and I didn't see how that was possible with those parts. Looks interesting, good luck! Edited January 24, 2014 by Hrafn Quote
Junpei Posted January 24, 2014 Posted January 24, 2014 Totally awesome! Can't wait to see them in action. After seeing what Hrafn said, i wonder if they could be used for gearboxes... TLH Quote
Doc_Brown Posted January 25, 2014 Posted January 25, 2014 Sweet! I would be interested in getting those parts, only I live far far far far far away. Quote

TLH I am not too sure if they could or not,but you could always get a set to test your ideas out... Sweet! I would be interested in getting those parts, only I live far far far far far away. I would not think postage would be any more than £10..... Quote
BobSmithHello55 Posted January 25, 2014 Posted January 25, 2014 Very interesting! It is cool to have that kind of gear instead of the regular 16 tooth. Quote
Alasdair Ryan Posted January 25, 2014 Author Posted January 25, 2014 (edited) I am pleased that some of you are interested in trying out these custom parts along with me. I do like to stick to lego made parts as much as possible but this I had to try and make because it can allow to you to pass a forth function though a turntable. With this part we can make mini excavators with a blade and expandable tracks while keeping it compact,or using it in cranes. You can now have all the motors in the lower half.

DrJB Posted January 25, 2014 Posted January 25, 2014 (edited) ... pass a fourth function though a turntable .... Nicely done ... but ... 3rd or 4th? I see only three functions going through the turntable. besides the turntable itself, of course. Edited January 25, 2014 by DrJB Quote
Alasdair Ryan Posted February 4, 2014 Author Posted February 4, 2014 (edited) I got the parts today and here is a picture. It does work,but the parts out of the box were a bit too tight and a bit short in length. In order for me to get it reprinted I will need at lest two people willing to spend £10 inc shipping.

SNIPE Posted February 4, 2014 Posted February 4, 2014 (edited) How do you move the light grey inner clutch ring from one 16 tooth idler gear to the other? Edited February 4, 2014 by SNIPE Quote
