Items Needed100 CD Spindle (cake box). I used one with 4 little keeper tabs.
Panduit Tak-Tape Container - ( link) - This is what I had on hand.[gal_img]1198[/gal_img]Kids restaurant drink cup. I get these when I go to Max & Erma's or Red Robin.
- 3" PVC Schedule 40 Pipe
- 4 CD/DVDs - Use some blanks or used discs - they are cheap.
- 4 2x2 Lego (or mega Block) Slopes (or mega Block)
- 4 2x3 Lego (or mega Block) Slopes
- Bench Grinder (a dremel would work)
- Drill press (or drill)
- Hobby Knife (xacto knife)
- Angle Cutters (GW snips)
- Circle cutter (optional)
- Various drill bits (9/16, 1/
Step 1Drill a hole in the center of the door stop. This should accommodate the CD spindle post. I used a 9/16 bit and rounded it slightly to fit on. A snug fit is better than a loose fit.
Step 2Drill a hole in the bottom of the drink cup. Again, the same diameter as the CD spindle post. A snug fit is better than a loose fit.
Step 3Place the used CDs as spacers in the bottom of the spindle. We are trying to raise the base to the same height as the outer lip. It took a mix of CDs and Clear protectors to match the height for me (2 CDs and 2 spacers worked for me). Once you know how many you need, glue them put glue on the spindle base, then drop a CD on. Hold it till try. Then glue between each CD/Spacer till done.
Step 4[gal_img]1202[/gal_img]Cut the top of the CD Spindle to the desired Height. I left mine a little higher so that the turret add-on I am making will be able to sit on it. It should protrude no less than ½" above the Door stop. I measured the height by placing the cup and top ring on the spindle and marking form there - (note - if you do not want to cut out the center of the Panduit container and just stack it under the cup, take that into consideration in the height. That just didn't look right to me).
Step 5Next we cut out the center of the Tak-tape container (if this is the way you are going). Measure the height of the take tape container - mines was .888 - or about 7/8" of an inch. You now need to measure this far down from the lip of your cup and measure the diameter. My cup was about 2.86 inches at this point - about 2 7/8". Unfortunatley you will not find a hole cutter bit this size. You can use a hole cutter scribing tool instead, or free hand the circle and cut it with a hobby knife (which is what I did with ok results).
Step 6Secure the Take tape container and the drink cup to the CD spindle. Since both of these are a flexible plastic, glue does not work really well. I would recommend using some green stuff to patch in the gaps and secure them to the base.
Step 7Glue the Door stop to the bottom of the Drink cup. Pretty easy, it should just glue in place to the spindle/cup.
Step 8[gal_img]1203[/gal_img]Create your pipes I cut 1" lengths of the Hose and put a ½" long piece of the Brass tube in each end.[gal_img]1204[/gal_img]You need to mark the hole locations on the Base and on the sides of the tak-tape container. Drill these to the proper diameter. Put the tubes in place and glue.
Step 9Create the Panels for the sides of the Observation post. This was made from a 2-1/2" long piece of PVC pipe. Using a chop-saw I cut the PVC pipe in half - resulting in two half circles (not two rings), and then in half again.[gal_img]1192[/gal_img]
I used the PVC pipe because the radius of the pipe is close to that of the cup. I failed at attempts to use Plasticard for this step. I then cut the resulting pieces at a slight taper to one edge. It may be easier to mark the taper and use a grinding wheel.[gal_img]1194[/gal_img]For the notches and rounded corner, I used the grinding wheel. I finished the edges (breaking the edge) with a Hobby Knife.[gal_img]1195[/gal_img]
Step 10Glue the Panels onto the Drink Cup. I set the widest edge of the panel on the top and centered them on the retaining clips on the bottom of the CD spindle. I gave them a ¼" overhang over the top of the cup. I Glued them then wrapped the whole unit in rubber bands overnight to set.
Create the Feet. These are two lego pieces glued together. I cut the lego nubs off with my GW Definition: Games WorkshopSnips and flattened the surface with a hobby Knife. I then Glued the 2x2 slope to the 2x3 slope as shown in the picture. I let the 2x2 slightly overhang the back of the 2x3 so that I would have more surface area to glue to the CD Spindle. Once dry, I then glued these feet to the retaining clips of the CD Spindle Base. You could attempt to round out the back of the 2x3 lego to match the radius of the spindle - or just fill the resulting gaps with green stuff (which is what I did).
