LEGO Techniques - Spin Doctor

A few weeks ago you may remember I picked up both a generation I AND generation II Ninjago spinner in my LEGO Finds. The seemingly divine intervention was a good chance to crack open some ratty spinners and see what made them tick.

The generation I spinner is an easy start. There are three tiny screws on the bottom. This allows the top piece to come off as well as reveals a chunky drop-forged metal piece. It even has a part number on it. I'm not a scrapper and only a fair tinkerer so I'm not sure what kind of metal it is. It isn't magnetic but it's much heavier than I would expect for aluminum. The surface is somewhat dull, but then again it's for weight, not show. The interwebs suggest it could be zinc. At under $1/lb, this 1oz weight would be worth about 6c. No point buying out the entire world stock of Ninjago Spinners for scrapping. It doesn't really taste like a zinc tablet though. Stainless?

The central fig stand was a little harder to figure out. It has a compression clip that goes through a hole in the bottom portion. I chewed the tabs up a little bit before I tried pulling from the top side. A good solid pliers grip on the upright portion, a little twist, and *BAM* my elbow hits the wall. The stand has no part number on it but the ring does.

Piece of cake, let's tackle the second spinner. The design of this one is different. Where the gen. I has a tapered bottom, this is flat with a protrusion only at the pivot point. The attachment method is also different. Instead of mechanical fastening, it's designed to rely on snaps. Ugh, how to pry that apart?

The fig stand can come out first thing. That gives a little more of a sturdy central portion to leverage against. Oh look, this one has a part number on it! Same design and everything. I'll assume it's the same part as the first one.

At first I tried pushing through the bottom holes to release the pressure on the snaps. This didn't work very well. After that I gently pried a flathead jeweler's screwdriver between the two shells and s-l-o-w-l-y used some leverage. There was some plastic cracking but the snap released soon enough. The other two were no easier.

Once these are apart, you can get the metal weight out. This one is a different design but has no part number in it, just a mold position stamp. The ring is a slightly different design from gen. I but still noticeable. The little nubs on the ends are too small to fit in a minifig arm, but too big to be used in any of the expected mini-pin places.

Since Bricklink has not been interested in these types of pieces for their catalog, look for these in the BrickOwl catalog soon!

LEGO Techniques - Duplo Plane Biopsy

For a fun little diversion this week I decided to dissemble the Duplo airplane from last week.  Appearances were that it was composed of 7 separate pieces.  I wanted to see what was really inside as well as play with some of those parts.  Could they be used exclusive of the airplane?

This assembly is held together with 9 screws.  A little jeweler's screwdriver has a narrow enough shank but still offers enough grip.  The screws aren't exactly tightened to a high torque anyway; just snug.  The grey base is clipped to the undercarriage so a little finesse is needed to separate them.

The undercarriage:

 The nose piece has a little hole which goes over one of the screw channels.  The hole is about 4.9mm, just a touch too big to get any good clutch on a stud.  It does have a part number molded in though!

The grey base is still attached with two screws.

Remove the two screws and the base is free.

The windshield can be removed from the fuselage.  It clips ever so slightly into the windshield hole in the front of the plane.  A little more finesse here and it slides right off.

 Two more screws remove a back panel from the plane.

The tail is now loose.  Those little nubs are larger than a system stud but too small to clip into Duplo studs.

The tail cone can now slide off too.

We are left with the main fuselage, stripped of all parts.

Total count, 8 pieces assembled as one.  Also 13 screws, all the same size.

Unfortunately none of these parts have any hidden gems for working with system.  Some of the holes in parts (such as the rubber cones) that pass over the screw channels can have bars and axles put through them.  I suppose they could be used for sculpting a Bionicle or Constraction type figure.  The windshield might have some fun uses for a large building or maybe a better Invisible Jet?  If my kids didn't want this thing back together so quickly, I might try doing just that.

I've tried adding these types of parts to the Bricklink catalog before but they were denied.  Expect to see these in the Brick Owl catalog in the very near future!

LEGO Techniques - DUPLO Figure Breakdown

Maybe you don't get to play with DUPLO much but I do.  I am a proud LEGOpapa of three little kidlets.  We've had DUPLO around our house for at least 7 years, more if you count my small collection from my childhood.  So I was looking at a newer DUPLO figure the other day and realized that there could be quite a few parts in there.

The first thing I noticed was a small round rod that seemed to be running through the hips.  Just push this... okay, not JUST... apply some good force with a blunt metal object and the pin will slowly slide it.  Turns out it's a 2.75L bar but a little thinner on the end thirds.  So any old clip will grip the middle but slide on the ends.  However, the bar ends are thin enough to be compatible with Modulex.

After you remove the bar, the legs will pop right off.  Then the hips slide out.  The hips hold the arms in place so those are then freed.  The difference in the DUPLO fig from a minifig is that the DUPLO figs arms are ambidextrous.  That bar goes through holes in the legs, hips, and torso.

After that the hair needs to be addressed.  The hair has a 5mm rod with a pinch clip at the end.  This goes through the head and connects into the torso.  By carefully mangling the tip, you can get it to release and come off the torso.  It then slides right out through the head.

DUPLO fig, now dismembered into eight pieces.
