Hi RPFers !

For my first prop building, i choose something easy to assemble but something i instantly wanted when I saw ALIENS recently for the first time.

To start, you'll have to pick up all the parts needed for the assembly, and it will be the most difficult thing since the Motion Tracker was made with 80's parts.

The motion trackers were made by Terry Reed. The basic shell of the tracker is a power drill casing, dressed with mostly photographic accessories.

Here is a list of what you will need :

- A KANGO 426 drill

I couldn't find one unfortunately, but you could find a nice replacement option in the Aliens Legacy forum, made by a member there :

Re: ALIENS - Motion Tracker build tutorial

I also wanted to give you some advices about how to search the parts...

It was a good chase, but through all the web, and in foreign languages...
I have found the main parts in Germany and in england.

So, you will have to use google translate, and search on the different ebay websites..
For instance, "remote control" is called "Fernauslöser" in german...
Or a "slide viewer" is called "Diabetrachter" in german too !

(Good luck for your chase ;) )

Re: ALIENS - Motion Tracker build tutorial

Now, the construction part :
(Sorry if some pictures are missing... I have lost a lot of pictures due to an iCloud pb... :unsure)

Once you will found the Kango drill, you will have to dissasemble it... and it is really painful !

First, remove all the screws and the inner parts, but be careful of the amount of greese inside...

IMG_1567.jpg


IMG_1568.jpg


IMG_1572.jpg


IMG_1574.jpg


IMG_1575.jpg


IMG_1580.jpg


IMG_1583.jpg


IMG_1584.jpg


IMG_1585.jpg


IMG_1589.jpg




Then, you will have to cut the drill extension with a Dremel

IMG_1592.jpg


IMG_1593.jpg


And sand the rest

IMG_1596.jpg


You will also have to, using a dremel tool, cut this part, following the lines :

IMG_1598.jpg


IMG_1644.jpg


Then, insert a thin grid inside (I took the front grid of an old speaker) :

IMG_1657.jpg


IMG_1817.jpg


Then, you will have to fix the metal disc on the front of the drill case, with a hole drilled in the middle and four holes, forming a square...
Then, you will have to mark the holes with a pencil on the drill, and drill them. Here is the final result :

IMG_1725.jpg


After this step, you would have to widen the upper hole, on the previous picture, with a drill, in order to insert the AV cables

Then, you will have to focus on the bottom of the drill, in order to insert a rotative switch :

IMG_1665.jpg


After my researches, I discovered on this board that it could be a release valve, from the sphygmomanometer... Since I don't found the correct one, I used a guitar switch !

IMG_1668.jpg


IMG_1669.jpg


Then, you will have to fix the swivels on the handle of the drill :

IMG_1688.jpg


IMG_1689.jpg


Here is the final result with the sling, after painting :

IMG_1829.jpg


To finish, you will have to drill a hole on the right side of the lower part of the drill, in order to insert the female jack wire in which you will connect the male jack wire located on the HAMA slide viewer :

IMG_1835.jpg


The female jack wire I used was really thin, but if you use an other method, you will have to cut some parts inside the drill.

And you will be done with the Drill case !!!

Then, it's up to you concerning the order... But I started with the HAMA slide viewer and the vivitar flash, Its parts will go up and down the HAMA slide viewer :

First, remove all the screws :

IMG_1599.jpg


IMG_1605.jpg


IMG_1606.jpg


IMG_1607.jpg


IMG_1608.jpg


IMG_1610.jpg


IMG_1611.jpg


Then cutting the rest :

IMG_1612.jpg


IMG_1613.jpg


IMG_1615.jpg


IMG_1619.jpg


IMG_1621.jpg


IMG_1622.jpg


IMG_1623.jpg


Then, remove the electronics inside, in order to keep only the buttons and the leds :

IMG_1624.jpg


IMG_1625.jpg


IMG_1627.jpg


Then, keep this sheet of paper and glue it on the top of the HAMA viewer, then, glue the vivitar part on it :

IMG_1617.jpg


IMG_1618.jpg


Here is the final result on the two sides :

IMG_1815.jpg


IMG_1816.jpg


Then, on the the HAMA slide viewer, insert your male Jack wire, on the upper side of the viewer :

IMG_1713.jpg


You will have to find a piece of plastic that you will placed above the jack, in order to create a straight edge. If you don't do this, when you will insert your viewer on the Drill, it will bend.

IMG_1716.jpg


IMG_1717.jpg


Then, drill a hole on the back, at the upper part of the HAMA viewer, in order to insert an AV cable there :

IMG_1659.jpg


And drill a hole on the front lower part of the Kango drill case, approximately at this location :

IMG_1822.jpg


You could find on the Kango drill, a sort of rubber part, located on the Kango wire, to give a nice finish :

IMG_1662.jpg


IMG_1663.jpg


And place the cable :

IMG_1828.jpg


And you will be done with the VIVITAR and the HAMA viewer !!

Then, I recommend to go with the HAMA remote, the HAMA self timer box, and the JoBo minilight, located on the upper part of the Kango drill case :

Take the HAMA selftimer box, and screw it on the left side of the upper kango drill part :

IMG_1643.jpg


IMG_1644.jpg


Then, take the HAMA remote control, and screw it on the right side of the upper part of the drill :

IMG_1647.jpg


IMG_1648.jpg


(Keep the remote cable apart)

Take your minilight and disassemble it :

IMG_1650.jpg


IMG_1652.jpg


Then, drill a hole in the kango drill :

IMG_1655.jpg


And use the hole already drilled in the JoBo minilight, and place it in front of the kango hole, then, screw them together :

IMG_1655.jpg


IMG_1656.jpg


And you will be done with this three parts and with the upper part of the drill !

Concerning the lower part of the drill, you can start with the MATCHBOX power unit :

IMG_1673.jpg


So, remove the screws, and with a flat screwdriver, remove the plastic cap :

IMG_1674.jpg


IMG_1679.jpg


Then, cut the box from 2,5cm, starting from the front of the box (where you will glue the CASIO panel).

IMG_1682.jpg


IMG_1685.jpg


You will have to screw it later on the lower part and left side of the drill case :

IMG_1691.jpg


(Final result with the calculator panel)
IMG_1806.jpg


IMG_1833.jpg


Then, you will have to fix the HAMA selftimer, on the left side and lower part of the drill

IMG_1631.jpg


Remove the screws at the back

IMG_1632.jpg


IMG_1636.jpg


IMG_1638.jpg


And fix it to the lateral panel :

IMG_1642.jpg


And it's should be finished with the main work !

Before putting the whole thing together, you will have to primer the parts with a sandable black paint, and slightly sanding it with a wet sandpaper.

Then, you will have to airbrush the parts in Brown Bess... Concerning the amount of thinning, for five volumes of Brown Bess, don't use more than 2 volumes of thinning.

IMG_1692.jpg


IMG_1693.jpg



Once the paint is dry, you will have to reassemble all the parts, and gluing the Olympus panel on the front part of the handle :

IMG_1696.jpg


Concerning the display of the Motion Tracker, it was made of a piece of MDF, aluminum strips and green hot glue.

IMG_1718.jpg



And the final result !!!!

IMG_1805.jpg


IMG_1806.jpg


IMG_1808.jpg


IMG_1809.jpg


IMG_1810.jpg


IMG_1811.jpg


IMG_1812.jpg


IMG_1813.jpg


IMG_1814.jpg

Marry me? That is great work. Wow.

That was a marathon of scrolling. Love to see properly detailed builds. Great job, looks fantastic.

Thank you for your comments and for the rep guys !

Sorry about the size of the pictures, I thought they would be shorter :unsure

You say this is your first build? Beautiful work!

Yes it is !
But when I see all I still have to learn here, I think I will wait some times for the next one ! :)

You had a lot of luck, I spent almost four months to spot all the parts !
Yes, the casing was very clean, but unfortunately, the guy who sold it to me knew what it was and the value of it.

Thanks for the kind words !

I hope you will find all the part for building it !

Great build! It's nice to see detailed pics also. Your finished tracker looks very nice. :thumbsup

I have a tutorial that has been up on my site for many years as well.

Motion Tracker Assembly Guide

That kango is nasty after you open it up!

Yeah, disassembling the Kango was the hardest part !

An absolutely gorgeous build. Not only that but the base really sets it off.

For the record, I have absolutly no desire to tackle something like this.

Thanks, the base was made with found parts... I were inspired by the scene when Hudson let fall his Tracker on the ground to rescue Newt !

Thanks for reading it, I am very honored ! :)
