For some time now, there has been some interest in performing chemistry experiments and the like at RevSpace, with PeterC having amassed a decent amount of glassware and chemicals over the past 2 years. Unfortunately, whereas we have stockpiled quite a fun assortment of chemicals, we are still missing a lot of glassware, equipment and above all a safe environment to do proper chemistry in. Project FumeHood will change this.

This project aims to provide a complete environment to safely do a very wide variety of chemistry experiments by:
* Providing a safe fume cupboard, made from chemically inert materials, to do the experiments in
* Providing within the fume cupboard all the amenities you expect in a proper chemistry lab: electric outlets, gas connections, water connections, vacuum takeoff and of course air extraction through a carbon filter
* Providing dedicated, safe storage for glassware and chemicals
* Buying, as part of the project, a wide assortment of compatible glassware
* Buying a few necessary chemicals
* Buying, separately, a hot plate stirrer

The fume hood will be located in the Werkplaats, right next to the exit, facing the lounge.

€26.01 over budget

== Fume Hood construction ==

Some fume hood construction details:
* Table height: 90cm
* Cupboard inside height: 95cm
* Width: 110cm
* Outside depth: 61cm
* Compartmentalized storage underneath fume cupboard, with doors
* Special mini-compartment with safe for extremely hazardous chemical storage
* Inside of fume cupboard is lined with glass fiber
* <s>Glass fiber is reinforced with aramid fiber bands for explosion-proofness</s>
* Table is toughened glass, for easy cleaning and chemical resistance
* <s>Two</s>Three steel bars run along the back and top with holes tapped with M8 threads every 10cm; lab stand-style rods can screw into these
* Polycabonate sheet single slide-up door with glove holes, on spring-loaded linear guides and with simple up/down retaining latches
* Main skeleton out of wood
* Connections on the inside:
** 2x230V IP44 PVC outlets
** 2x barbed hose connectors for water (to water mains or circulating pump)
** 2x barbed hose connector for bunsen gas/argon
** 2x special (?) connector for vacuum take-off/pressurized air
* Soviet army style cylindrical carbon filter on the exhaust, followed by a 450m3/h or more fan
* Table has a 4cm lip to contain spills.
* <s>Fire door. No automatic fire suppression.</s>

== Glassware ==

We will be ordering the following glassware, all 29/32:
* Rods, clips and connectors for latticebuilding
* 600mm Leibig condenser
* 400mm Vigureaux fractional distillation column
* 500mm Dimroth condenser
* Thermometer stopper
* Vacuum takeoff
* Parallel neck adapter
* 75 deg adapter (distillation setups, etc.)
* Glass stoppers
* Soxhlet extractor (+possibly joint)
* 50, 100, 250 and 500ml roundbottom flasks
* Keck clips
* A 500ml drop funnel (which we'll abuse as a separatory funnel as well)
* Waste bottles (soda lime glass) + caps
* Reaction plates and crucibles

== What are we going to do with the fume hood? ==

Of course, we're not building a big, expensive project like this just for the fun of construction. We do intend on doing a fair amount of cool chemistry. A nonexhaustive list of the projects thought up so far:

* Making a lithium-ion battery (also involves project Smeltoven)
* Gold, palladium and platinum recovery from computer components using the cyanide pathway (also involves project Smeltoven)
* Chip decapping
* Making sodium and/or potassium metal using the new Nurdrage method
* Playing with project DIY solid-state stirrer
* Anodizing aluminum (and doing it right this time!)
* Making sodium silicide (for hydrogen production)
* Demonstration project: glowsticks (TCPO method)
* Demonstration project: copper salt crystal growth
* Demonstration project: basic electrolysis
* Demonstration project: Clock reaction
* Making aerogels
* Synthesizing organic and inorganic dyes

== Construction ==

[[File:fumehood_construction1.jpg|400px]]

Done:
* Create the main fume hood frame
* Clad the back and sides with sheet wood to square everything
* Make the table support
* Install extendable feet
* Get a bunch more 44x44mm wooden beams
** For mounting the drawer guides
** For mounting the inner paneling
** For supporting the roof?
* Make a roof
* Size the inner paneling, do not mount yet
* Undercoat all the inner wood surfaces
* Make the latticework
** Make logically spaced 10mm holes in tube stock, corresponding holes in paneling
** De-plate nuts and weld them onto the stock
** [Partially done] Make a bunch of additional smaller holes to bolt onto paneling
** put everything together with countersunk bolts in the wood and nuts on the steel
** immobilize nuts (either with self-locking nuts or locking fluid)
* Create a steel support plate for the fluid connections
* Undercoat all the exposed wood
* Install a lip at the front of the table
* Line the inside of the fume hood with polyester resin-impregnated glass fiber. This needs to be done in sections, laying the fume hood flat on whatever side is being worked on, otherwise we're going to get droop
* trim off any protruding glass fiber bits, repair bad bits
* very accurately record the positions of all the holes, we won't be able to see them through the gelcoat!
* gelcoat all the glass fibered surfaces. Don't forget the pigment paste!
* drill out all the holes previously covered
* Make a decision on how many drawers we want, how large, if we want cabinets
* Install the fluid connections
* Build and install drawers
* Prime and paint the extraction fan
* Mount the extraction fan
* Mount steel straightening frame to front of fumehood
* Buy (RU58) and install the window
* Mount stiffening bar and lifting handles for the window
* Install a noise dampener on the fan outlet (outside)
* PeterC buy that glassware dude! I want to cook!
* Make faceplates for the drawers
* Decide on what size latticework we want and cut threads on sized pieces of stainless steel
* Install the filter
* <s>Possibly install anti-tipping legs</s>
* Finish the outside and prime whatever hasn't been primed yet
* Make mounting holes for the electric outlets
* <s>Amfi will decorate the outside</s>
* <s>Straighten the outlet/switches</s>

Still to do:
* Polish and paint the window frame
* Make pegs for the window to rest on in OPEN position
* Make a door for the cabinet, also maybe shelves?
* Put anti-slip liners or... whatever in the drawers
