That undercarriage business is one of the things that makes whiffery so much fun; challenging us to come up with solutions to problems, and learning new skills in the process. We definitely have to do that far more often than regular modelers.

I did 'Technical Drawing' when I was at school, and got top marks for it when I took my exam in 77. Myself and a couple of others used to fly through previous test papers managing to complete several during each class, correctly too I may add. So looking at drawings and working out ways to measure angles is something that I know how to do.

I helped a guy on Britmodeller who had both plan and side elevation drawings for an S-61N sponson which he could not get to look right. I taught him how to work out the correct size. That did get the old grey cells a bit of a workout in trying to give the instructions in writing. Worked though.
So finding out the angle for the undercarriage is really fairly easy.

Co-ordinate geometry is a very handy bit of knowledge to have in this field, that's for sure. 

Anyway, back to the undercarriage.

I have been fettling the recesses for the top of the main Legs.



You can just make out that there is now a rectangular slot where there used to be a round hole. I used a chisel with a 2mm wide blade, backed up by a scalpel. I have yet to determine how I am going to make sure that the legs are at the correct angle as can be seen in the picture below.



With that tread on the tyre compared to what was provided in the kit, I opted to get a pair of wheels from the KP Tempest as replacements. I will get them cleaned up and painted tomorrow I hope.

One advantage to the type of glue I have used to glue the canopy in place is that it can easily be removed.

There was dust on the inside of the canopy which was bugging me as it was rather obvious so I felt I had no option but to remove the canopy and get rid of the dust.

Much better,



and it only took a few minutes to do as well

It's annoying isn't it.  When you first notice its there you think "ahh, that's OK.  I can live with that.  It doesn't really show much." but then it starts to get to you, becoming a little more irritating each time you look at it or think about it and it starts nagging at you, gnawing away at your confidence in your build, that voice in the back of your head becoming louder and louder until "ALL RIGHT, I'LL PULL THE BLOODY THING OFF OK.  Geez, gimme a break will you".

Or is that just me?

It's probably not just you, but it's certainly not me.

Tonight I have painted all the tyres and added more glue around the canopy after finding there was a hole. So not much achieved today, but every step is nearer the end.

That canopy glue is interesting. It doesn't seem to have shrunk much. Once set, is it rubbery like white glue or hard like superglue?

White glue based as far as I know. If it had gone hard like superglue I would not have been able to remove it to get rid of the dust. Way too dangerous if it was like that as I would most likely brake the canopy and it's the only one I can find, sprues and part built parts of the kit were all over the room.

I am finally finding a use for two items I have had for some time, a set of 'Helping Hands' and a jig for setting wings etc level.



I had been thinking of trying to hold the aircraft the right way up and adding the undercarriage legs with the tyres on them 'on the ground' as it were. Way too difficult when you think about it to achieve, let alone adding glue at any point!

So I realised that if the aircraft was upside down then I could hold the axle of the undercarriage leg in the helping hands which are poseable so I could set them at just the right angle. Next thing was to cut a guide at the correct angle.

So some scrap card was found, in this case, it was from a large serving spoon, it does the job though.



I labelled the card so that I would hold it the correct way around and set up the undercarriage leg which was good enough at the first go



At the moment I am making sure that the superglue goes off before I remove the clamp and set the other leg. I might change the way I set the model up for that as I want to ensure I have a matching angle for both legs.

Another guide, attached to the first, across the underside of the model?

I should have but that was beyond the information I had for the angle of the legs in relation to the centreline.

Looks not bad though



Until you look at it from head-on though   



No prizes for guessing what I am doing tomorrow   

Gondor

While trying to sort out the leg it sort of expectedly fell off 

Not too bad a thing in a way as I was able to clean up the socket so that the leg could be attached at the correct angle. That sentence reminds me of an episode of the TV series "Your Life In Their Hands" which was about Surgeons, the episode I am thinking of when of a hip replacement. BIG drills and Mallets!

Anyway, with the leg free I was able to apply some glue to strengthen the leg near the top of the part where it goes around the wheel as the plastic was flexing a bit more than I liked and was probably going to break if nothing was done.

The end result is below.



Much, much better I think. Of course, now that the legs are glued in I find that I have a set of drawings that look to be almost 1/72 when printed on a sheet of A3 paper
