Actually, putting the screws in from the top was a better solution.

Reading ahead, guide 6 - step 27 also tells you to cut the syringe plungers. This time it tells you to cut them flush with the white plastic end. I cut them just below, as step 29 tells you to. Hopefully both approaches are fine?

I also had trouble with this step. When you are doing this for the first time it is hard to know how much cement to apply. Filling about a third of the gap, while the needle is in the gap, turned out insufficient. It was then very hard to wick additional cement in to fill the gaps.

Filling two thirds of the gap was then too much. Cement squeezed out and started to melt my gloves :) I also then slightly damaged the underneath surface of the 6mm thick piece, which is now covered with the white layer.

I can see that with practice, this is not too hard, but its tricky to get it right the very first time. Perhaps the kit should include some additional large round pieces that are glued first, just to get the technique right. Just a thought.

I know it seems obvious (now) but we should probably note that the tape SHOULD NOT BE REMOVED until the glue is dry. The glue does not stick to the tap. Oh, and don't do this step late at night after a long day at work. You can add that to most of the instructions :)

This step says "place two nylon screws" as the previous step did. I presume it means add two nylon nuts? To hold the screws loosely in place? Otherwise they drop out when you pick it up.

When you open the cement it is sealed internally with some metal that says "cut this out". You can puncture it with a screwdriver and pop it out. Not sure how you cut it.

You also need a funnel to get the cement into the squeeze bottle. I didn't have one so I used a large syringe (not one from the kit).
