Dennis Mulhair Posted October 3, 2014 Share Posted October 3, 2014 Well its day 2 and I thought I had better make a start before I get so far behind I won’t know what I’m doing. It was a good idea starting a day behind Danny as I can have his blog open whilst I’m putting things together. Pictures 1&2 are self explanatory but 3 is my attempt at getting the fin post central. I also took Danny’s advice on laminating the fin post from 2 pieces of 1/8 balsa. I will fit the second laminate tomorrow when everything is dry and solid. By the look of picture 4 it seems to of been a success. I look forward to your comments. Well that’s all Folks!! Be sure to follow the next exciting installment.

Dennis Mulhair Posted October 3, 2014 Author Share Posted October 3, 2014 Not sure if the above is correct but I could only add these pictures by pasting them into the body of the blog. I did create an album but could not move them across Dennis Quote Link to comment Share on other sites More sharing options...
Terry Walters Posted October 3, 2014 Share Posted October 3, 2014 Hi Dennis, Best of luck with your build - nice and neat from the pics in your album. You can put the pics in the blog now they are uploaded to your album so the hard works done. Click here and it will tell you how.

Terry Walters Posted October 3, 2014 Share Posted October 3, 2014 Well great minds think alike Dennis! Have a read of the link I put in above and you can do it properly. Enjoy your build! Terry Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted October 3, 2014 Share Posted October 3, 2014 I think it looks good Dennis but am not sure, mine looks bigger it took me a while to learn how to post pic's but the thread Terry highlighted worked for me.

Nev Posted October 3, 2014 Share Posted October 3, 2014 Looks good so far Dennis. For me this build will be a case of little and as often as you can. Adding photos is pretty easy once you have them in your album, look out for the camera icon. Edited By Nev on 03/10/2014 21:12:07 Quote Link to comment Share on other sites More sharing options...

Dennis Mulhair Posted October 10, 2014 Author Share Posted October 10, 2014 Hi All, Its been rather slow progress and I had no problems with the fin but that is where the joy ends! My main reason behind joining this build was to get help and assistance with something I have never completed before. Seeing that I had all the plans, cowls and canopy it was just too good to be true. Well it seems like I don't have the same plan as the rest of you! My equipment was ordered back in the late 90's and is a Chipmunk 1 and does not have all the extra drawings for the Mk2. See the enclosed photo's and compare to Danny's rudder posted on his blog on the 8/10/14 @ 15:05. Is it possible to get the missing dimensions to keep in line with everyone else? I am also having issues around the rudder build. Again from my pictures the ribs from the wood pack are too small and seem to taper from 3/8" to 1/8" between the lower one and the top one. Yet the fin post tapers from 7/8" at the bottom to 9/16" at the top. Are these ribs too thin? Is it best to make new ones of the same thickness of the 1/4" sheet at the front of the rudder? I think that's it so far! And finally it seems I can copy the pictures from my album across into this blog using Internet Explorer and not Firefox.

Danny Fenton Posted October 10, 2014 Share Posted October 10, 2014 Hi Dennis, ooo an original Nexus plan. it does look like it has been updated. I would suggest that you make the 1/4 rudder leading edge exactly the same shape as the fin rear post, split it lengthways and remove 1/32 from each side (rudder core will make this back up) And then make triangular ribs that taper from the leading edge to the trailing edge in a straight line. It might be easier. And don't worry we have all had issues with the thickness of the rudder, it will be the same when it comes to the elevators, don't trust the plan implicitly (I know that goes against the grain).... Try using this pic to help work out the shape. If you place an X on your plan by measuring a 30 degree angle up from the rudder horizontal line formed by the underside of the aerodynamic balance. place your rudder core over the plan and rotate about the X, until the distance from the existing outline to the position of the the rotated core is 16.5mm as shown, then draw around the rudder core you will have a new curve, its very close indeed. Hope that kind of makes sense?? Cheers Danny Quote Link to comment Share on other sites More sharing options...
Dennis Mulhair Posted October 10, 2014 Author Share Posted October 10, 2014 Thanks Danny, building has recommenced Dennis. Quote Link to comment Share on other sites More sharing options...
kc Posted October 10, 2014 Share Posted October 10, 2014 So everyone else is building from the Traplet plans but Dennis M is building from the Nexus ( now MyHobbyStores) plan! Same designer, same wingspan but different plan services, so is the construction exactly the same? Presumably if bought in the 1990's then Dennis M is using the Nexus/MyHobbyStores canopy and cowl but the modern Traplet lasercut parts? Will it all fit?

Dennis Mulhair Posted October 10, 2014 Author Share Posted October 10, 2014 KC, Looks like I'm going to find out very soon. Will keep you updated but you will probably know by the amount of requests for help I post!! Good fun this building lark. Up till now its only been model Loco's that I have made. Better keep up my flying practice as I'm still on a trainer!!! Dennis Quote Link to comment Share on other sites More sharing options...
kc Posted October 10, 2014 Share Posted October 10, 2014 I would suggest looking carefully to see that the cowl seems like it would fit over the precut engine bulkhead etc. There could be various thicknesses of fibreglass used by different manufacturers, maybe different attachment points etc. Quite easy to modify a bulkhead at an early stage, much more difficult later. Horrible job to hack a nice cowl around to fit! Canopies are usually trimmed to fit so that might be OK. Presumably you would just follow how the laser cut parts fit even if the plan differs so that wont present a problem. Good luck! Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted October 10, 2014 Share Posted October 10, 2014 So far i can only see one line that differs from the later drawing and thats the additional mkii rudder outline. Why would the rest of the plan differ?Havent seen it so cannot say for certain, but would seem odd to me.CheersDanny Quote Link to comment Share on other sites More sharing options...
kc Posted October 10, 2014 Share Posted October 10, 2014 Usually plans sold to rival publishers are changed in some way ( for copyright reasons I suppose). So I expected it to be a new drawing with changes. If not then no problem. Quote Link to comment Share on other sites More sharing options...
Dennis Mulhair Posted November 5, 2014 Author Share Posted November 5, 2014 Well folks its been a while since I have posted anything but I have finally got a rudder & fin in a condition that I think will be OK! Danny, when you you glue in the hindges or have you done that already? Now on to the the tail plane. Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted November 5, 2014 Share Posted November 5, 2014 Hi Dennis I glued the fin part of the hinge but not the rudder. Not sure I have done right though as the rudder part will have to be covered before fitting so access to the hinge for gluing may be awkward. However you will not get access to the nuts to assemble the hinges the other way, and you don't want the fins glass work to get into the hinges.....

Dennis Mulhair Posted November 16, 2014 Author Share Posted November 16, 2014 Hi All, Finally managed to make a start on the tailplane. I followed Danny's initial build on page 4 & 5 of the "Poor Mans Spitty" blog. I've completed the bottom sheet stage, the next is the hindges and elevator. I think its straight and if its not its not fat out. If there is a discrepancy could I cleare it by damping the sheeting down and clamping it straight? Danny what do you think?
