Lego Technic Parts made with JB-weld

[Boxerlego]

Well It has been some time since I shared something on the forums. I've been pretty busy but I've still been building. Check out the LEGO part I had to Custom make for my next project.

Looks like a strong bond! I have no idea what it could be used for though

[bonox]

i'm sure we'll find out soon enough :)

I'm going for option 2 or 3 though. As a general building technique, I disapprove because it's hard for people to follow you. I'm not against part mods, but it's much easier to cut down a soft axle for barman's engine extractors than to glue up a set that probably requires a jig to get accurate. For you to make something yourself, I do approve :)

I'll be curious to see where it goes that couldn't be achieved with a pair of 3 bladed propellers with holes cut out couldn't.

@Nalyd997: Its very Strong and its one stud thick. It uses will include everything that is LEGO. Think of it like a Super Bushing.

@Bonox: Hopefully I can finish what I'm building SOON, I have my new project mostly completed on the LEGO parts just need a few more things and it will be done. I agree as a general building technique I wouldn't approve either. JB weld can get messy, The First one I made everything was going perfect with the first three bushings but things started to get messy when I added the final four bushings on. My mistake there but I ended up salvaging everything except the bushings. I use one of my favorite LEGO parts to be main part to make this. This Wheel Hub here. The inexpensive common bushing is what make this idea promising.

I could have built this in LEGO but that means using rare and some what expensive hard to find parts that are prone to breaking because their half a stud thick and eventually be in the need of fixing in the end overall. So I decided to take things in this direction. Usually I'm puting JB a none LEGO object to bind with a LEGO part, First time ever I JB multiple LEGO Technic Bushings together like that.

Here is a look at my next part. Bearings! I've been working on this for awhile now so I got a couple of Ideas at the moments on how I want to make the bearings work. One method is by trying to fit regular Technic axle but because its a Metal Hole then a Metal Axle.

An LPE powered car? A skateboard? Who knows?

IGUS company has in offer XIROS plastic bearings... maybe try this... it will be nice to have something like this in regular LEGO offer

Those bearings look and sound awesome, plastic bearings that need no oil. I know these metal bearings here have grease packed in them. Plastic bearings would be incredible to see in regular LEGO. The potential uses for them would be interesting to see. What kind of uses would you like to see bearings be used for?

[Boxerlego]

Here is my next development with my custom JB LEGO part. In order to get this part where it is now I had to go through 3 phases in construction 6 in total. In the beginning I had to remove and reattach one of the bushings on the part because it didn't sit flush with the rest of them. Can you tell which on it is??? While this part is very needed I am going to continue to expand on this LEGO Technic pattern and uncover it mysteries. Right now the total number of bushings on this part is 13, I plan to add 6 more to complete the 3rd layer of bushings which brings the total number of bushings to 19.

Can I ask what do you need such specific part for? It is going to look like snowflake with next level

[darsedz]

something like that can be "replaced" by 2 of 44374

Sure, It Is going to be for my magnets but who knows maybe one day I will make some wings and helicopter is here.

I have several of those parts. Some of them are cracked. I believe that pearl style plastic makes them crack easy. Plus their half a stud thick.

No Jb-weld this time. Behold Clutch power like you never imagine.

I'm kind of scratching my head as to what's going on here. Could you post more details?

[Rockbrick]

I once used jb weld on an engine block core plug that was leaking coolant never on lego

I certainly can man, I already have 3/5 of the project competed. I'm going to get a poster board some time this week so I can take pictures of what I have got going now. Details as for the metal rod and the LEGO gear. The Metal Rod is measured in standard inches (not metric) 5/16 is it diameter. The closest measurement I can get (with out going over) to 8mm which is the size of the center hole for the bearings which is measured in metric. Now because the metal rod diameter is in inches this gives some free play for the metal rod to be inserted in the bearings. The way the lego gear is connected on the metal rod is done by clutch power through the 4 axle pins and centers the metal rod with the gear very well the only problem left to solve is the tilt of the gear. Once the gear is tilt is adjusted to mesh with the adjacent gears with out any rough/hard spots while its moving around then the finial thing left to do is JB weld the gear in place on the metal rod and now you have a metal rod that can fit with the LEGO system. I will make a new post and put some pictures up of this later. Currently the JB weld part is the step I haven't done yet.

Jb weld can be used on almost anything. Here is a link as to what Jb-weld can be used on. I find myself using Jb to fix things made of plastic most of the time. I just recently fix a plastic caster wheel on a small roller cabinet while ago.

JB LEGO Engine Mounts

Here is my latest idea JB idea. Purist brace yourselves for this one because it probably the most purist you can get with JB weld and LEGO. JB LEGO engine mounts. There are some things to over come with spacing. The engine blocks here are not spaced out properly for the crankshaft to fit in between because this was a spur of the moment idea and It was designed from this part down below which wasn't intended to be a Engine mount in the first place.

this looks like a part of the Large Hadron Collider, or maybe the drill of one of those tunnel boring vehicles.

[Sylvian]

Finally seeing what you are up to i dont see a reason to dissaprove, since what you are trying to build doesnt solely revolve about lego itself.

Sure does.

Thanks Sylvian. Here is a look at what I'm building. Its finally got to the point where my idea is taking form.

I'm building a 24 magnet pole rotor for my perpetual motion machine

The difficult part about this is that here on the rotor the axle is the center support while on my stator a metal hole bearing is there. So far I have came up with two option #1 is keep the LEGO axle and figure out a axle style of connection on the bearing with JB weld #2 is fit the metal hole with a properly sized metal rod and figure out how to mount the 24 magnet rotor on the metal rod. Both ideas pose there own problems however idea #2 poses the most risk to the JB LEGO part I made one while idea #1 poses the most chances of failure, putting JB welding inside a bearing hole with a LEGO bushing inside isn't the smartest idea for a ball bearing I need to find a idea that doesn't involve JB weld here.

[DrJB]

You've done a lot of work and that in itself is commendable. I must ask though, wouldn't a 3D printed part be a 'viable' alternative? I'm sure efferman can cook up one with as many bushings as you need.

[Boxerlego]

Thanks DrJB, for me 3d printed parts is not a good viable option. I have little to no experience about using them. 3D printed parts poses problems within itself to figure out and developing a 3d printed part will just still end up being a prototype for something better.

Today I figure this group of unique connections out with the metal bearing and rod. The bearing hole here is the same size as the hole on the end of portal hub. This could be the solution I've been looking for to connect the LEGO axle with the Bearing hole It fits like a charm.
