Special Project--Accuracy


1 stars
I know nothing of the accuracy of Catapults or Trebuchets, or even if someone out there can help. We're shooting a television show involving stunts that damage a house and we would LOVE a trebuchet or catapult to hurl something. The question is--how accurate can they be? AND is there a one available in the Denver area anytime soon? Any thoughts? email me at

The show's called Disaster House. It's a fun/crazy show for sure!

These two questions must be answered:
When will the engine of distruction be needed?
and
What do you intend on hurling?

If you have enough time (say one week) you could hire local unemployed carpenters and builders to do the job.
Add a beer bonus if they finish on time.
We have enough plans floating around that you could buy and adapt to your needs.
Do you use set engineers? Tell them what you need.

After the filming is over, you will have a trebuchet or catapult to rent out to the next guy.
(We get requests like this all the time.)

Or, you could hire my firm, Evil Genius Labs for only Five Million USD. Conditions to include owning the rights to your DIY Network and flinging flaming pianos.
We use only Craftsman Tools.

Sorry, we are not available until March of 2012.

Best wishes for a great season,

Walker

PS, both catapults and trebuchetti are reasonably accurate after being zeroed in by incremental adjustment.
They can not be expected to be able to sniper shoot a house without walking the shots in. Unless it's at very close range.
2nd attached photo below is from a 10-Lb pumpkin at 300 feet. Yes the car was the target, hit on the 2nd shot.

Accuracy can be a good as needed, given video set-up and editing control.

Most types of catapults can be very accurate. If you don't mind shooting from close range (edited into long range) you could punch holes through a bulls-eye, knock out single struts or beams, target a window, knock out a chimney, whatever.

Figure out what you want to do first, in fair detail.
Punch holes in a wall? Point specific hits? Slo-mo shots? Total demolition? (Fire?)

Figure out how the shot will be set up.
All close up? Long range/wide angle? Point of impact close-up?

Figure out how much time you want to put towards the catapult itself.
History review? Build sequence? (On a DIY show?) Operation details?

Take those and other factors into consideration then select the catapult that best fits the time schedule, costs, transportation issues, etc.

Myself, I'd go for a Ballista style of machine, launching bowling balls.
You could get high-energy shots easily with good targeting ability. High angled shots would be tricky but I suspect you don't need those.

There are good sized trebuchets (or at least one that I know of) in the Denver area. Look up the Aurora Jack o Launch to see an example.

Wiki Syntax
Bold text     __text__
Italic text     2 single quotes (').     ''text''
Underlined text     ===text===
Colored text
~~#FFEE33:text~~ or ~~yellow:text~~. Will display using the indicated HTML color or color name. Color name can contain two colors separated by a comma. In this case, the first color would be the foreground and the second one the background.
Deleted text     2 dashes "-".     --text--
Headings
!heading1, !!heading2, !!!heading3
Show/Hide
!+, !!- show/hide heading section. + (shown) or - (hidden) by default.
Autonumbered Headings
!#, !!#, !+#, !-# ...
Table of contents
{toc}, {maketoc} prints out a table of contents for the current page based on structures (toc) or ! headings (maketoc)
Horizontal rule     ----
Text box     ^Box content^
Centered text     ::text::
Dynamic variables
%Name% Inserts an editable variable
External links
use square brackets for an external link: [URL], [URL|link_description],[URL|link_description|relation] or [URL|description|relation|nocache] (that last prevents the local Wiki from caching the linked page; relation can be used to insert rel attribute for the link - useful e.g. for shadowbox).
For an external Wiki, use ExternalWikiName:PageName or ((External Wiki Name: Page Name))
Square Brackets
Use [[foo] to show [foo].
Wiki References
((page)) or ((page|description)) for wiki references
Lists
* for bullet lists, # for numbered lists, ;Word:definition for definiton lists
Indentation
+, ++ Creates an indentation for each plus (useful in list to continue at the same level)
Tables
||row1-col1|row1-col2|row1-col3||row2-col1|row2-col2|row2-col3||
Title bar     -=Title=-
Monospace font     -+Code sample+-
Line break
%%% (very useful especially in tables)
Multi-page pages
Use ...page... to separate pages
Non parsed sections
~np~ data ~/np~ Prevents wiki parsing of the enclosed data.
Preformated sections
~pp~ data ~/pp~ Displays preformated text/code; no Wiki processing is done inside these sections (as with np), and the spacing is fixed (no word wrapping is done). ~pre~ data ~/pre~ also displayes preformatted text with fixed spacing, but wiki processing still occurs on the text.
Comments
~tc~ Tiki Comment ~/tc~ makes a Tiki comment. It will be completely removed from the display, but saved in the file for future reference. ~hc~ HTML Comment ~/hc~ makes an HTML comment. It will be inserted as a comment in the output HTML; these are not normally displayed in browsers, but can be seen using "View Source" or similar.
Block Preformatting
Indent text with any number of spaces to turn it into a monospaced block that still follows other Wiki formatting instructions. It will be indended with the same number of spaces that you used. Note that this mode does not preserve exact spacing and line breaks; use ~pp~...~/pp~ for that.
Direction
{r2l}, {l2r}, {rm}, {lm}Insert resp. right-to-left and left-to-right text direction DIV (up to end of text) and markers for langages as arabic or hebrew.
Special characters
~hs~ hard space, ~c~ ©, ~amp~ &, ~lt~ <, ~gt~ >, ~ldq~ “, ~rdq~ ”, ~lsq~ ‘, ~rsq~ ’, ~--~ —, ~bs~ \, numeric between ~ for html numeric characters entity

Because the Wiki paragraph formatting feature is off, each line will be presented as you write it. This means that if you want paragraphs to be wrapped properly, a paragraph should be all together on one line.

Plugins

Note that plugin arguments can be enclosed with double quotes ("); this allows them to contain , or = or >.
