A NEW DAY, a new module. Bright and early, Sam gathers our parts for the transporter plate assembly.
Conrad had quite a challenge tracking down the original 1701 parts!
Enterprise's bridge transporter was only in service from 2272 to 2278--all bridge transporters were gradually phased out in scheduled service upgrades. The module shells were easy enough to lay hands on, but the mechanics and buffers were lost--Conrad finally located them in
two different fleet scrapyards. They could be restored, but the mounting frame was too damaged to salvage. Fortunately, Willie whipped us up a new frame using the original dimensional specs. Our miniplates themselves are unavailable, having been reassigned to engineering duty on the T/T
U.S.S. Anaximander NCC-3804 in 2279, and they are still on her. (For those not in the know, the
Anaximander has a long and storied history, and is almost as famous in trucking circles as the
Enterprise was among the exploratory set.) Conrad found two new-old stock miniplate units in a warehouse 'way out in Tellarian space, which are the same model number and production run as the originals on 1701. Like I mentioned earlier, Conrad's OCD comes in useful sometimes. He's been like a bulldog making sure every possible scrap of materiel for this project is as authentic to as-flown as possible.
If you've never seen an NK
TopSide shipping crate in action, it really is a marvellous thing. It is designed specifically for bulky items, or stacks of smaller items, that require manual offloading. It has a self-contained small hydraulic pump, lift, and batteries that enable its contents to lift straight up by degrees out of the crate; revealing them at shoulder-level for unpacking in an ergonomically-optimal manner. Here is Sam activating the crate, (about 50% raised now,) giving us our first peek at the contents snuggled inside. A very nice but unusual way to ship odd old parts like these instead of just strapping them down to a pallet. Conrad must have really talked up their importance to the scrapyard--this is the next best thing to having them delivered gift-wrapped!
When the team arrives, they waste no time on this new challenge. Tomas and Eddie are unloading the
TopSide, Mike tackles the NOS miniplates, and Sam's cutting the tiedown straps on the new frame. It's not exactly a
simple jigsaw puzzle--we're reassembling a collection of very old, dusty, disused, and obsolete parts that involve very high currents and radioactive components that rip apart atom-by-atom anything it touches. So, a typically fun morning for Starfleet engineers! What could possibly go wrong?
So far, so good. Using the old blueprints, we found all parts present and accounted for, and the serial numbers confirm the unit was used on
Enterprise. Considering the state of the damaged frame, the components themselves were very straight, and we mounted them with hardly any correction needed. As far as possible so far, circuit continuity has checked out, so on we go! We install the inner and outer cove shells above the assembly in anticipation of installing the module shell around the frame.
Next, the miniplates bolt in. (As expected from NOS items, they fit perfectly and everything lines up.) More testing, double-checking, and finally hooking her up to a massive EPS lead and the little computer. As before, the computer will 'fool' the transporter into initiating a cycle, as well as running continuing diagnostics. The computer will instantly cut power at the first sign of an internal error. Malfunctioning transporters are
never a good thing. People think of transporters as safe and foolproof--but that's only because the systems are thoroughly engineered with multiple redundancies and fail-safes built-in to prevent alignment errors, buffer errors, sync errors, Heisenberg errors, stream errors, and so on. Nevertheless, firing one up for the first time is always a trepidacious experience even for the most hardened engineer. So we do what any good engineers would do...we break for lunch first!
After lunch, and here we see two electrical engineers doing what they do best. After sequentially and systematically going through a gradual power ramp-up, Tomas monitors the plasma stream as Sam slowly brings up the energizer. I'm amazed at how much power transporters draw: even initating an empty stream dims the lights in the entire building. This won't be an issue when we parallel it into the bridge batt/gen unit, but we may have to re-think our plan to have the energizer running continually on display. Maybe we'll have it cycle every ten minutes or so...we'll have to run the numbers and see.
At this point, it may be useful to talk about why bridge transporters were so briefly used on Starships, and why they haven't been used since.
The "Phase II" development plans had included accommodation for a single "mini-plate" on-bridge transporter, and from eight to sixteen similar transporters at strategic locations onboard ship, which would allow rapid delivery of parts, samples, equipment, etc. among labs, maintenance, engineering, stores, and so on. By the time of "Refit" development, the bridge module had been expanded, featuring
two independent plates and pattern buffers, with capability for site-to-site, vector, and stock retrieval modes on either plate.
Mini-transporters were an experiment in miniaturization. Transporters until that time took an entire room's worth of associated machinery. Sizing it down to fit on a bridge (or in a cabinet) involved not just reducing the size of the plates, but reducing the
plate resolution as well.
This meant that only inert, non-organic items with a relatively uniform molecular structure could be beamed. (Metallurgists discovered that the technique, as
Low-Resolution Reconstruction, actually was a tremendous benefit in tightly bonding certain alloys, and LRR is used in large-scale metallurgy to this day.)
Although miniplates were designed for easy transference of small items throughout a Starship, they proved troublesome to maintain, and tests demonstrated that repeated low-res beaming of the same item could result in molecular drifting, (like making a copy of a copy of a copy.)
Bridge transporters were rarely used in the field. Their small size was found to be inconvenient, for larger items could be vector-beamed directly to the bridge, and small items were usually accompanied by a technician when needed. In practice, actually, the primary use for the bridge transporter was discovered to be stock retrieval of foodstuffs during night watch shifts--a practice Starfleet Command deemed to be unacceptably wasteful of ship resources.
Alternative modules, including status boards, and gravity, cargo, or tractor beam control were designed to retrofit the existing module shells for certain Starship classes upon filing a request with Starfleet Operations. Enterprise's bridge transporter was replaced with status control boards in 2278.
Minitransporter technology along with LRR has developed over the years. The ability to use LRR with stored datafiles led to the development of the modern replicator, and rapid mat/demat of LRR shells was used in early Holodeck development.
With the mech in place and tested, the module shells can be fitted. Top tip from Mike: put the inner shell on
first, in case you have to tweak the frame slightly so that the plates fit flush to the shroud without unsightly gaps. Clamp the frame to the deck, then put on the outer shell.
With that, we'll call it a day. There's still some afternoon left, but we were here early, worked hard, and it's been a stresser. Tomorrow will be easier--viewscreens don't explode if you make a mistake. Ha!
