On February 3rd Peter and I took a field trip to Mark Bayes place who generously let us use his massive workshop to paint the fiber-glass surfaces.
The first step was to prep the fuselage so I could paint the bottom. Using Frog Tape, another great tool of the trade, attached newspaper to the bottom edge of the fuselage on both sides to flop over and cover the sides (and top) of the fuselage to ensure no paint accidentally splatters on those surfaces. Also used wax paper to cover the tail area that is not being painted.
I then turned the fuselage onto its top and painted the entire bottom red. I worked the paint from front to back, ensuring no globs existed along the way to help ensure a smooth finish. The painted bottom can be seen in the featured image above.
The last task for the day was painting the floats, you guessed it red :). As I completed a floats paint job I hung it up to dry.
On January 16th I continued work on fiber-glassing the bottom of the fuselage. This day was focusing on applying fiber-glass all around the edge of the bottom of the fuselage as well as on the nose. This ensures the seams, spaces between where the bottom connects to the sides, are thoroughly covered.
Also fiber-glassing of the nose of the aircraft to help ensure water tightness there too, preventing the balsa from getting soaked since this will be in the water, partially, and leading the way.
On January 14th I continued with the fiber-glassing process. This time, seen above, I applied fiber-glass to the keel of the fuselage. The process was similar to before, this time cutting strips that would wrap over the keel and about equal parts on each side. This is done prior to the remainder of the bottom to ensure there is good coverage along the joints / corners where the keel is attached to the fuselage.
Afterwards I started wet sanding the wing tips. For this I used special sand paper that I dipped into a small bucket of warm water. This keeps the fine fiber-glass particles being sanded away from becoming airborne, you want to avoid breathing these in!
You can see the finished sanded product of one of the floats below:
On Dec. 18th I could really start to see things coming together as I worked on putting the bondages for all the control surfaces into place.
The first step was to ensure the hinges fit into the slots off the main surfaces (wing for ailerons and fin & stabilizer for the rudder & elevator respectively). Once confident of that and also checked with placement of the corresponding control surface attached as well along with their range of motion it was time to mix up a batch of glue.
Prior to gluing the hinges into the slots I prepped them by spreading Vaseline onto the hinge joints to ensure no glue gets into the join, which would prevent the hinges from working properly, don’t want that! I then applied glue into the slots as best I could as well as onto the hinge and then placed them into the slots.
Once that was done I applied glue to the other end of the hinges, seen above. I kept the container below to try and avoid making a mess from excess glue dripping from the hinge as I applied the glue. Before connecting the control surface I did my best to run glue into the slots on the ailerons, elevator & rudder pushing it in with the stick / using gravity to let it seep into the slots.
I then slid the control surface onto the hinge and confirmed all hinges were in place, movement was there and then left them to sit and dry. This concluded another building session and you can see the result below.
Note: I did one control surface at a time, applying glue to the hinges and connecting using the process above prior to moving on to the next control surface.
Been on a hiatus over Christmas which has allowed me to catch up on my blog posts. I am now all caught up and am hoping to get back to building this week! With luck I won’t get this far behind again, lol. Don’t hesitate to leave a comment and let me know you are out there 🙂
On Nov. 27th I started the process of covering the elevator and rudder for my Seamaster. This day consisted of covering the ends and trailing edges of the two control surfaces. This is done first in order to ensure the edges are properly covered and ensure there is no exposed balsa in the end.
In the next session on Dec. 5th I finished covering by cutting two rectangular pieces, one big enough to wrap around the elevator and the other around the rudder. The key here is to make sure it is big enough to cover the widest/longest part (the leading edge in this case) with enough to wrap around the surfaces beyond the trailing edge.
The covering process is similar for both. Starting with wrapping the covering around with the leading edge aligned somewhere in the middle you tack/iron down the covering to the leading edge.
Next you pick a side and iron the covering around the leading edge and to the side of the control surface making sure to work your way from the centre out to the three remaining edges. When ironing at the edges make sure it’s securily ironed at the edge itself and be careful not to have the excess covering touch (cut excess as you see fit). Once done the one side you can trim the excess covering along the edges before proceeding.
Next, flip the elevator or rudder over and repeat on the other side. Starting with rolling the iron over the leading edge and continuing to iron the covering to the other side of the surface starting at the centre of the leading edge out into the middle of the side and working your way out to the three remaining edges. Then trim excess covering. This process left me with covered control surfaces.
On Nov. 26th I covered the fin of my aircraft. This entailed cutting to pieces with some excess for each side of the fin. I ensured a straight edge was used along the bottom and top. I ironed along the top edge first and then worked my way across the surface and folded the one side around the front.
I incurred a few more wrinkles then I would have liked, but pick my battles I must, lol. You can still see bits of balsa sticking out at the bottom, but this will be covered when doing the top of the fuselage as it will be cut around the fin and will go up a bit as well as down each side, tapering off.
I do apologize that my last few posts haven’t been ‘as good’ as past ones but I have been playing catch-up while I’ve had some down time.
Please feel free to leave a comment to let me know you’re out there and even start a dialogue 🙂
On Nov 24th I finished covering the top of the stabilizer. Since I already had the center piece with the convex curve completed it was a matter of cutting two pieces of caution yellow covering (over-sized) for each part.
The process was completed similarly to the bottom in that I started by ironing down the straight edge along the middle of the stab and then working my way around the edges, as well as rounding the covering around the shaped leading edge. I then cut the excess off of the trailing edge and cleaned up any of the other edges as necessary.
Once that was done I used the heat gun to shrink the covering, making sure now to spend to much time in one spot and to keep moving with the air blowing towards the center. I needed to make sure that I didn’t heat up the glue of the covering creating the seal around the edges as well as making sure I didn’t heat a hole through the yellow covering or the orange covering that was previously applied. Hence, keep moving and checking to make sure surfaces are not getting to hot, pausing as necessary.
You can see the completed look in the pictures at the top and bottom of the post.
