I dont post much, but I cant help to say...keep up the good work. It inspires me to attempt something of this size and compexity. As I'm sure it does others. To me the Byron corsair is about the truest scale looking of all the ones out there.

Well, it has been a while since I have touched the Corsair. I sheeted the horizontal stab, glued on the lite ply trailing edge and the end caps. I need to put the stab tips in location and sand the airfoil to shape. The rear fuse section has not been cleaned, so I will do that today.

Thanks Peter

I am on holidays right now, so I have some time between finishing my kitchen, and other chores. Besides it has been so hot here, 30's so the basement is the place to be. The P-47 is just siting until I go to another contest in a couple of weeks, besides, I would love to fly the Corsair this year even in primer

Horizontal stab is shaped and sanded. need to work on the control surfaces next.
PS, thats my new tiled counter top in the picture

did it myself.

yeah tell me about chores!

We are about to start building a new house, land settlement occured on Tues and we are now going through all the options with the builder, every time we come up with a bright idea they go KA-CHING $$$, KA_CHING $$$

Anyway will be all good in the end and I will have a 9m x 6m x 3m high shed plus a 3x6m gabled awning off one end so bucket loads of workshop room.

You did a bloody good job of the tiling there, want to pop over and do ours? I'll even thrown on some beers and a barbie!

Wer'e actually have a coolish winter for a change, down to about 8C overnight which is cold for us, days creeping up to about 18 - 20C though today is overcast and a few showers so don't think it will get that warm.

Next week the logan Club are hosting one of our Southern Cross Warbird events so will take the P51 out to that. Was hoping to have the big Seafury going for that but made a mess of the new spinner by dropping it on the concrete and putting a huge dent in it that ruined it.

so a new one is on it's way from Roy Vallincourt and I will get him to do the machining for screws and the prop openings as I am not set up for that sort of work. For an extra $50 is it well worth it.

cheers
PEter

Your winters sound very familiar to our summers

Was playing with the stab attatchment. The instructions call for it to be butt glued to the fuselage, and a piece of 1/8th ply attaches the two sides together at the rear. A hole is cut in the fuselage for the plywood to be one continuos piece. Earlier discussions on this thread have me concerned with the overall strength, with just a butt joint.
Here is my plan.
I drilled a small pilot hole on the plywood endcaps ensuring they were exactly the same, transfered this hole onto the fuse root attachment. I am currently using a small rod to see how it works...............perfect.
My plan is to enlarge this hole, melt out some foam and use a 1/4 inch dowel, 10 in long to support the front of the stabilizer on both sides. When I permanently glue it on I will use some expanding glue (gorilla) which should give more strength and piece of mind. I have not heard of any real issues with the Byron method, I just think it could use some beefing up.

Craig.

Craig,
well at the momenht it is bucketing down and coldish so I am goofing off on the PC instead of downstairs

As for your stab, my thoughts are that butt joint is a failure waiting to happen. I really do think 1/4 dowell is a bit on the light sode as well. For mine I would be getting some carbon fiber tubing about same size as arrow shaft. Very light and mega strong.

Suitable light ply support on inside of fuz to distribute the load as well.

cheers
Peter

Even though I used a stronger and thicker plywood rear spa. My stab cracked along the butt joint and was only held on by the plywood after about 8 flights. I used carbon rod about arrow shaft size at the front . I glued it in with aero-poxy. It went all the way through and was glued to the former near the front of the stab. I also drilled a few holes through the fuse in to the stab along the butt joint. This allowed the aero-poxy which I joined the stab with on my second attempt to push into each side and lock the two pieces together. Solid as a rock since then.
Good Luck
Paul

Thanks Paul for the information. I figure if I do it right the first time, should eleaviate any issues down the road.

More work on the tail this afternoon.
Enlarged the hole on the fuselage and horizontal stab pieces for a 5/16th short dowel. Slid the tail on and man she is snug

you can see the dowel on the inside in picture #3, and there is room to rienforce.
Marked out and cut the 1/8th by 3/4 plywood rear spar location. I have it inserted, with the tail and man is she solid.
I also cut out all the tail feather pieces today so I hope to start putting those together soon.

Craig.

Craig, as Paul said arrow shaft is the way to go. IF you made up some ply plates for the inside to the correct shape and had them in there loose till after you glued the stab and shafts in place you can then very easily epoxy them where they need to be. I've seem similar technique used for fitting wing joining tubes on a large mossie.

Looks like it is going to rain here again so will stay home and do panel lines on the P47

cheers
PEter

That is my exact plan, to rienforce the piece after she is all glued in, lessen the stress on the glass wall.

Yes, When I start, I find it hard to stop.

Constructed the rudder, placed it on to have a look. Emphanage is slowly taken shape.

now that is really starting to look like a coarsair, excellent work mate.

I spent most of the day marking out panel lines and then corecting for "best fit" giventhe scale limitations of the kit. Pretty happy with it so far, got one side of the fuz and the bottom done, about 25% through other side. Once done I will attack the stabs, elevators and then the wing.

cheers
Peter

Did some pin hole filling. Gave the tail section a shot of primer, the pin holes just poped right out. Filled them with some spot putty and will wet sand a bit later. Figured I would get most of the filling done prior to perminently installing the tail section.

One piece of advice I will give you, even though I am sure you know it. Try to save every gram of weight in the tail, this plane more than any other I have,was grossly affected by tail weight. The shortness of the nose and the possible weight of the glass fuse and stab components at the rear, contribute to a sutuation where saving even a few grams by getting all extra primer and putty off, lightening holes in the sheet of the stab and rudder and carefull application of glue will save you a bunch. Like you can see earlier in my cowl, I added three and some pounds of steel BB's right in the cowl lip to get mine to balance. Anything you can cut or sand off no matter how insignificant it may seem will definitely make a difference on this plane.
good luck
Paul

Paul gives excellent advice here. My Byron Corsair required 6 pounds of lead in the nose to balance! Even at 31 pounds it was one of the best flying warbirds I've ever owned.
