Draper 1200W Router Kit

I'm going to build this bloody electric ukulele if it kills me! I'm serious about this! And if you don't believe me, here's the proof... I've just bought a router. I opted for a budget Draper 1200W Router Kit. I know nothing about routers, so this is a real journey of discovery for me. There's a video at the bottom of me unboxing my new toy and here are a load of pictures of me checking it out and putting it together.

Draper 1200W Router Kit
Stock number 90088; Part number PT1201VK 

Here's a shot of the "Pivot Rod Trammel" attached to one of the rods
I think you use this as a guide for doing curved routes

The supplied router bits. From left to right...
4.0mm radius Roman Ogee bit (with bearing)
12 x 25mm Straight Bit
12.7mm x 90 degree Grooving Bit
6.3mm radius Cove Bit
6 x 25mm Straight Bit
9.5 x 32mm radius Rounding Bit (with bearing)
And at the bottom is a spare collet. One was fitted.

Here are all the loose bits. I've fitted the rods into the parallel guide fence
Top right are template follower and pivot rod trammel
Bottom are collet, 2 x nuts for guide fence, 2 x screws and spanner

OH BUGGER!!!! The bloody dust extraction port is damaged!
I've filed a claim with the seller... hmmm...
The top and bottom parts are meant to fit together with hooks
at each end. The fit isn't good and someone's forced it
causing the port to crack by the fitted nut! AAAGGGHHH!

I've fitted the 16-18mm template follower here using the two screws
that hold the dust extraction port in place. I think the two nuts
pictured are supplied in case you don't want to use the extraction port. 

I haven't figured out what these are for... yet...
My first hunch is that these are spare and relate to raising and lowering
the router bit? Any hints welcome.

And finally, here's the great unboxing I mentioned. It's just a bit of fun!

Seeing as I haven't actually used my router yet, I'm not going to be giving it a Triple-B rating. I'll maybe do a follow-up later.
