Custom Fire Truck.

So "The Workshop" hosted another build-off last month.  This time the theme was Fire Trucks!  Here's my entry for the build.  Turned out nice and I learned some new tricks in the process.  Getting more comfortable in this "medium" and the cool part is I'm learning some neat things I can apply in my metals classes.  I leave bits and pieces of builds on my desk at school during the week and I've had a couple of students ask about them- some are interested in trying their own builds and it gives me an opportunity to not only show hands on working skills but also a LOT of different problem solving ideas.

My starter pic.  Wasn't really sure where I was going at this point so I kept my options open.



Eventually I decided I had to go with the Ford.  First step was to drop the front as low as it could go.



Then try and figure out how to make it loooonnngg.





Ended up combining a base with the overall body of the truck. 







Fenders.  This was tricky but they turned out pretty nice.  Wanted to completely enclose them- old fashioned skirt style- but that didn't work out.







"Water Tank".  Again, something new.  Forming the curve was a challenge.







Ladder time!  Most expensive part of the truck.  Had to buy a whole roll of wire.







Ladder mount and some more cleanup.  We added a friendly competition halfway through the build to see whose ladder was longest / tallest.  Mine missed by 1/4"...

Bolt is attached to the ladder pivot, the nut is attached to the base, allowing the ladder to swivel and raise.








Time to clean up the cab!







Paint and assembly.  Should have used some better paint, but this deeper red made me feel more "vintage" so I went with it.






Custom skirts made with chrome pin stripping tape.



Test fitting.



Details.

Ladder tilt.



Hose reel.







Cab detailing. Windshield wipers were a booger to do.





Single stack.


Ladder assembly.







Stock vs. Lowered.


Decals and more assembly.










Few more pics of it, then we can move on to the next project.









And there you have it, "ENGINE" 7.

W.I.P.

Work In Progress...  Been playing around with Sketchup and have managed to learn myself a few new tricks.  Gotta love Sketchucation and all of the cool rubys and plugins you add on to Sketchup.  A few months ago I downloaded and printed this engine from Thingiverse.



It works great, but I've wanted to design my own engine for a while now so here's where its at.  I thought it would be cool to make them "stackable" so this is my expandable air engine.  The idea being you print one, and it runs off of compressed air like the one above.  If you wanted, you could then print another long block that could be plugged in behind the first, but with the piston and valving running at a different timing- 180 degrees out, 90 degrees out, whatever.






Little hard to understand, but heres a shot of the rotary valve.



Still working on getting tolerances figured out but its close to actually running.





Getting closer.  At the rate I work on projects I might be done by June!  Of 2018...
