Week 06  This week the stbd lower main spar

The bits we received

And what we did with them

Exactly the same as week 2, but I had a problem.  The bottom and two sides were glued together, seemingly without problems.  They stayed straight and flat.  But when I came to put the tops to the spar in place the notches on one side didn't line up.  With the notches lined up at the rear of the spar, they were misaligned at the front.  See the picture below.

This had me puzzled, as the parts were unlikely to be wrong.  It all became clear when I looked at the bottom of the spar closely.  

You can see that the spar side at the top of the picture is pushed to the right, and the one at the bottom is pushed to the left.  This was what you call damned unlucky, but how to fix the problem.  I have simply enlarged the slots with a modelling knife so that the ribs will fit.

I am covering my model so I'm quite happy to leave the enlarged slots as they won't be seen.  If you are going to leave your model as an open frame model you could fill the gaps in with some plastic wood after you have fitted the ribs.

Here is the completed spar.

Hot tip of the week

If something doesn't fit, or seems wrong, don't panic.  Look closely at your parts and workmanship.  Work out where the problem is, and think about a solution.  There is often an easy way to rectify small mistakes.
