In spite of the challenges, I think you're doing a brilliant job. The Dolphin is my favorite aircraft and I'm looking forward to seeing yours completed.
Cheers,
Bud

Starting to take very nicely Squiffy, resin is not the easiest material to work with but you seem to be managing okay, looking forward to further updates.

...I would use the kits struts as templates only...

Hmmm... fitting the struts was going to be the next job. I've just left the paint on the lower wings drying so came to have a look on here whilst it did.

What is the problem with the kit struts?

he was just saying dont use the kit struts cuz resin is brittle and therefore the struts can be. many resin kit builders use other methods for struts and use the kits parts as a template to make the new parts. methods include use of brass strutz, contrail extruded strut material, squashing brass tube with a steel wire inserted then shaping with files. using wood as bamboo skewers or toothpick types to make struts.

Ah, I see. I'll see how I get on with the kit struts first...

IMHO brittleness of resin is not a problem for struts in 72nd scale. The kits are small and the load from the top wing is generally small. I admit that highly tightened structural rigging with stiff fishing line may be too dangerous. But if you ues an elastic thread as I do for rigging, nothing really happens. I have built some Choroszy resin kits (two Macchi M.5s, Lohner S30, Sopwith Dolphin), one Ardpol kit (Halberstadt Cl.IV), one TopGun (Friedrichshafen FF.49) and always used the kit struts. I encountered no problem with them. The key point is to have them straight. If they are pre-bent, then warming them up in hot water facititates bringing them back to correct geometry.

I do use structural rigging, which, in this case, has proved neccessary.

The 4 cabane struts are glued to the top rim of the cockpit and being that they are 4 seperate pieces do not offer much stability when fitting the top wings.

I didn't want to fit the interplane struts before adding the top wing as I could easily have misjudged the amount of (back) stagger needed so I glued the wing to the cabane struts to get the amount of stagger right.

Unfortunately, as there are no holes for any kind of positive location of the wing, it was twisted several degrees out of parallel to the lower wing but this was corrected by fitting 4 interplane struts (held in by tape) and pulling the wing round by tightening the rigging and gluing it in place. The struts were removed and replaced (glued in) one by one.

It all looks to be pretty well aligned now.

Very good work.

Looking very nice indeed, what I can see of the rigging it looks well done.

Outstanding Squiffy. Seems you are very good at correcting the alignment through your rigging process!
