Track what about the prop makes it mechanical (i.e., lights, electronics, motors, etc.) and create a list of materials needed.
Design a technical drawing or instructional manual (brief) that contains the measurements and dimensions per material used to create the prop. If the prop is more complex and requires detailed computer attention, use CAD.
Create another brief with the assembled pieces and list the measurements of the combined pieces (the finished prop).
Begin configuring the different materials used, based off the brief.
Assemble all of the measured and cut pieces together to create your mechanical prop.
Ensure that the mechanical prop moves, rotates or lights up properly before securing its final touches with shellac, gloss, carvings, silver-plating or any other finishing touches needed.
Track which prop(s) need to be re-created for safety reasons, and construct a list of materials needed.
Follow Step 2 above.
Create another brief with the assembled pieces and list the measurements of the combined pieces (the finished prop).
Carefully mold the original props in a soft foam or rubber. If the prop is not too complex, the mold may be directly fabricated from a safe and soft material. Note that more careful attention to detail needs to be paid when constructing a stunt body (a created person used to fill in dangerous or violent scenes).
Secure the completion and functionality of the prop before implementing its final touches with characteristics like carvings or designs.
Track which prop(s) are featured more significantly than others and need special attention, then construct a list of materials needed.
Follow Step 2 above.
Create another brief with the assembled pieces and list the measurements of the combined pieces (the finished prop).
Begin configuring the different materials used based off the brief. Create duplicates (backup) of this/these items.
Ensure that the hero prop accurately resembles the designated item.
Track which material(s) are needed to best resemble the piece of art (i.e., foam may be better suited for unfinished granite, whereas a finished or slicker lightweight material looks more like bronze). Construct a list of materials needed.
Follow Step 2 above.
Create another brief with the assembled pieces and list the measurements of the combined pieces (the finished prop).
Begin configuring the different materials used based off the brief.
Ensure that the statue accurately resembles the designated item before putting on its finishing touches and glazes.
