Thanks for clearing that up and I'm happy Jeff and Merlin are still friends.

Graham,

I just got your e-mail and I sent you one back. If you happen to check out my thread today before you ship the canopies please apply the aluminum frame as you suggested. I'm not very good at that type of work so I would greatly appreciate you doing it. Let me know if I owe you anything for the aluminum and extra trouble. Also e-mail or post here if I caught you before you shipped them. I would hate to have to ship them back so you could do it.

Thanks,

Barry

Since I received my prop adapter and can now cut the hole in the crank the size I need it. I've decided to build my radial engine while I'm not doing anything and just waiting on pearts again. It's a WASP Radial by Williams Brothers for $116.00. It is the closest thing to looking real that I could find. It might even fool some people because it is 3-D with exhaust, spark plugs and ingition wires. It will all depend on how good a paint job I do. I'm going to paint it to look loke some of the radials out on the market for $4000.00 plus dollars. It won't sound the same but it will sure look the same but it will have 9 cylinders.

Here is a picture before I build it,

I had a good day today and for once everything went easy. I got as far as I could in 4 hours building the engine. Heres what I've got done so far. It should really look good when it's all painted up. They even sent a decal like the real engines with a serial number on it. Sorry it's blurred but my camera isn't the greatest. I'm going to use an airbrush to give it an aged look on the cylinders and crank. I'm not sure on the colors yet. Any suggestions for a F4U-7 engine.

I got my heavy duty 4-40 ball links and threaded rods today so when I'm done with the engine I can get back on the throttle and choke. I'm still quite aways away from finishing the engine but I am just going to stick with it until it's done. It weighs about 5 lb's so far. I'm going to replace the plactic pushrods with the same diameter aluminum tubing. I think it will look much better that way. Plus I have to paint the 16 spark plugs and wire them up. I'm debating on painting it or not. The insturctions say it is correct the way it is. I think flat black and gray might look more realistic. Then maybe add some rust.

Radial looks great, but I agree; too clean looking! Nothing a little rust and flat black misting can't solve. Good luck.

Gibbs,
2 items,
The engine should be set back in the cowl quite a ways, look at some corsairs from a 3/4 front view to get the idea,
and 2 the colors as molded are correct. Gloss gray Crankcase with Gloss Black cylinders. the weathering should look like oil staining and chipped paint to be authentic. Pushrod tubes, unless you're doing a pristine show airplane, should be painted the same color as the cylinders.

Have fun It'll be great!

Bob,

I re-did my throttle linkage and will do the same for the choke. Heres a couple pic's. Is this what you had in mind. There 4-40 rods and ball links with washers on the top bigger than the plastic ball link. No way they are coming off now. I will use new nuts when I finally finish it up. This is just for setting end points and testing the engine. The 2 4-40 rods are wrapped tighly with copper wire and then ssoldered together. I tried to pull them apart and they are solid. I have done this method before when I wanted adjustment on both ends but on smaller planes.

The dummy engine cost $116.00 plus shipping. I am very particular about the scale looks of the things on this plane. The paint job I decided to be a new engine versus an old one. The whole plane is going to look like it just came off the production line. They all were new once in their lives. Here is the dummy engine with the paint and one set of pushrod covers installed for the pic only. The one spark plug still has to have the white paint applied but I am done with it for now and moving on to the construction again. I am going to make a wiring harness for it and make it look as real as I can. I got my plywood ribs and after I finish with the choke linkage I am going to get on that wing. What would you suggest to do to have 2 threaded ends without using an all threaded rod which is weaker than solid rod with a silver solder and copper wire wrapped splice in the middle? I have done this as I said before and vibration hasn't effected it yet. Plus I spliced the rods wher I can keep an eye on them for fatigue.

I finished up the choke linkage and started on the right wing tip panel. Before I could glue anything in place I had to add the dowels for keeping the wing in line. Don only had the bolt in the wing tube to do this. David put in dowels with back up blocks so I just did the same. I used Polplar dowels and Poplar back up blocks that I had laying around. I drilled both of the plywood #11 ribs so the wing would line up correctly. There wouldn't have been any way to do this once it was built. The reason there a little burned is the blade in my table saw is getting real dull. It's time to replace it after 5 years. I got my moneys worth. Tomorrow I'll start to glue the ribs in place to the bottom spars. Heres what the blocks with the dowls look like. I hate to say it but this thing is getting heavier by the day. But it's better to be safe than sorry. It needed the blocks and dowels.

dont glue in your wing tubes and just tack the end ribs , wait till you have all three panels then final glue everything this is where two inc meters comes in handy

Thanks for the good news that came to late. The ribs are already glued in place on the right wing tip panel. I did line everything up before gluing anything in place. I inserted the wing tube thru a couple ribs of the tip panel and then did a test fit of the tube and dowels with the center section rib # 11. All line up well so I glued the ribs in place. Plus I don't use CA glue and you can't tack glue with Elmers carpenters glue. You can have that finger covering CA but I'll stick to what I like best. I like to be able to adjust things after the glue is applied such as if they are a true 90 degrees.

I've got the right wing panel almost framed up. I still need to put on the leading and tailing elde. Then when everything is good and dry I'll slide in the wing tube and epoxy it in place. I had to get one of my plywood rib # 11's really wet and straightne it out. It was bowed badly. By tomorrow it should be straight being clamped between two pieces of hardwood that spans it's length and height. Here is the wing tip panel and the rib before I started to straighten it. I'm also making a ring to go around the front of the firewall that I will router to make the round front on the Corsairs where the cooling flaps open and close on. I have 1/2 done and the second half is drying. I need to do it in two halves so I can use my bandsaw and cut it out in the middle to make it look like a ring so it won't interfere with anything thats inside the ring, IE engine and misc things. It will be about 1" wide all the way around except for the cowl hold downs and the custom exhaust spots.

Braydan,

Is that being built from a kit that your completely bashing to get what you want or scratch built. It looks great. Keep posting pictures and explanations here. I'm always looking for ideas and ways to make my Corsair look more realistic. Whats the wing span on that baby? What size engine are you using in it? Post some pics of the engine when it's done.

Thanks,

Barry

Brayden,

I read your post again and forget the questions about size and kit. It's going to be hard with TF's scale lines to make it look true scale but I'm wishing you luck. Keep me posted on your build.

Barry

are you sure that your plans are scale i was talking to another builder who said taylors plans were too far off to be true to scale hes drawing his own set to get it exact to 25%

Vern,

Who are you talking too? You need to state you you are addressing so readers know who and what your directing your posts to. Mine is not a plan by Taylor, it is designed and drawn by Don Smith. It is as close as I could find to true scale for a 1/4 scale Corsair. Then every builder expects to have to modify and bash it a bit to make it as close as possible. Anyway I finished my cooling ring for the firewall and epoxied it in place and then sanded it by hand until it was the proper shape to resemble the front of the Corsair if the Cowling was off. Here it is.

rack,

I don't know. I haven't built the center section yet and even if I did it would have to off enough that I would see it. Remember were not building real full scale aircraft here. Just big boy toy's.

Who we need here is Luke below is a some pics of the plans and a 3 veiw the tips are a out but might be an easy fix being there huge blocks of balsa but the gull part of the wing (IF this was the part of the wing you was refering ) i cant realy tell but i am no expert and my 3 veiws might not be the best and need to be blown up to 1/4 scale to tell better.

Winston,

Thats how I built mine if you go back and look at the tip or ribs 16 and 17. I notched out the bottom spar at #16 as I did and you did on your TF Giant to get the washout correct. I'm cutting up my cowling now so I can make cooling flaps to go with my cooling ring. I don't need this expensive engine overheating and burning up.
