2011 updated 13/01/2012 December 2011 - Last week of December and the workshop is "still running hot". Part of the catching up while Bill has been away working.
More balance weights, getting good at casting these things now.
Hardware for linkages in and hooked up and working.
Wing sections and elevators in various
stages of putting together. The balance weights need to be finished off,
before mounting on the elevators.
Wing sections glued and clamped while the resin is curing.
Taking the wing in its jig outside in the bright light on a good sunny spring day.
Bill checking clearances and finishes before the elevator can be assembled. Bill has been away working in Joburg. He is back, so the "fun work" has started again. The left wing nearly there. It is sitting in its jig, as it is becoming quite heavy to move around by an individual. Also, so it can be pushed outside for some workshop space. The dark green part, is the main spar section, made up of many layers of cloth and is extremely strong. The control linkages are
assembled Bill demonstrating
where the flap will fit in. Pieter and Bill cutting this front section off the foam core of the right wing with the "hot knife". It requires a steady hand and accurate
co-ordination following the jig cutting line, Going well...... .......3/4 the way through. ....and this is the cut face left after removing this front section of the wing core foam. Man that hot knife works well!! Buttering the surfaces to be join with
"micro". Cling film is used on the table to make Joining the surfaces and using weighted bags to hold the section on the right against the other section. Bill and Pieter nailing a straight edge to the table to keep the foam cores aligned. They have been checked for alignment and straightness. Mean while, Pieter had started setting up the jig supports and has mixed the "micro" to glue these right hand wing sections together. Pieter has buttered the joint surfaces
with "micro". Bill is clamping the plank straight edges,
to hold the wing October 2011 - Both Bill and Pieter are multitasking these past months. Bill squeezing out the excess resin
through the peel ply after Pieter helping wet out the peel ply with resin. July 2011 - Both Bill and Pieter have been busy. The metal plate has been roughed out and is still in progress. The underside of the engine for measuring the mounting and cutting profiles. The engine mount stand has been made and is portable for future moving and testing. Bill is busy with the winglets seen on the bench. February 2011 - Its been a
busy time during January and February. The main spar has many layers to
put down, and is now completed. Then the decision for an engine has
been made, so other ideas and decisions can be made and the budgets
planned.
The spar coming along. On the right is Pieters canard coming along.
Pieter was also busy with his canard and has finished the layers and started the filling.
Some of the fibres are visible which will be bonded to the ends.
Nearly there. The spar completed and Bill is happy with the outcome. The wings are next and this one is being set up in the jig and held in position for joining.
Bill has decided this is the engine for his plane and is busy loading up after purchasing it. What on earth is it? A 13B Mazda rotary, which is fuel injected and turbo charged. There are a lot of parts which come
standard for a motorcar which are not needed. The side with the spark plugs. This is a wooden template for the
plate which will become part of Bill has been busy cleaning the starter. The standard injector body with part of the inlet manifold. The cast iron exhaust manifold which the turbo bolts too. The turbo and wastegate body. The standard alternator which comes with the engine. The inspection and stripping process
will take some time. The wings
