    Nice one Martin. That's truly amazing!

    I should also add that both sides of the balsa need a good wetting, especially if it’s thicker than 1/8”. I did manage to make a rolled tube from 1/8 balsa, so it’s a versatile method for creating complex shapes. Edited By Bob Jennings 1 on 08/08/2019 00:04:37

    Hi Chris, it’s really simple. I’d wear a mask and gloves... brush ammonia onto the balsa, leave it for 10 minutes and you’ll see how pliable the wood fibres become. The bending can be enhanced by carefully assessing the best grain direction. Hold the piece in place until the balsa dries and it will have ‘set’ in shape. An additional coat of ammonia will allow further distortion. It is amazing how the balsa returns to its original rigidity once the ammonia has evaporated off. Try it, it saves hours of planking.

    Sweet! Stop teasing... I need to focus on my Nimrod and the Sabre... and...

    It's been a while since the last post. More glueing and pinning to get the Nose section to a near enough state prior to starting the tail section. I want to get all the big bits done together and then glass the whole lot once i'm sure the fuselage will fit together. I'm leaving the structure open here so I have access to the formers when I install the bracing tubes across the holes you can see inside. Just got to ammonia some more balsa to fit the upper cockpit area. It may need a sub-former the support the curve. Another addition to the plan!

    More power to your elbow Pete. I'll be following with glee!

    I'm with you on the sheeting route. With the Nimrod nose section nearly done, I have a good idea of the amount of stress a sheet of balsa can take with ammonia persuasion. It should be a doddle and end up a bit lighter overall. I'm not sure how much weight the planked glue joints add but, like you say, it'll be an interesting challenge.

    Not sure how I can change that!

    The big question is... Working airbrakes? Jettisonable tanks?   Edited By Bob Jennings 1 on 30/07/2019 18:16:03 Edited By Bob Jennings 1 on 30/07/2019 18:16:57

    A better shot of the chamfer holding the edge in place, no glue.
