john stones 1 - Moderator Posted January 4, 2016 Author Share Posted January 4, 2016 Cheers lads, I think laminating's something I'll do more often, feels much stronger. I weighed it out of curiosity. John Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted January 4, 2016 Author Share Posted January 4, 2016 Set of ribs cut individually ala Peter block em together for spar slots though, no spars long enough in scrap box though, so it's first spend of new year John Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted January 5, 2016 Author Share Posted January 5, 2016 I can't get owt done for reading others blogs I read a thread on here about old balsa..here's a bit that came up on the Mary Rose (captain was building a Wot 4) I like to strip my own spars for cost and you get them pretty much the same strength.

john stones 1 - Moderator Posted January 5, 2016 Author Share Posted January 5, 2016 Slec balsa stripper and a set of main spars. and still plenty of sheet left. John Quote Link to comment Share on other sites More sharing options...
Biggles' Elder Brother - Moderator Posted January 5, 2016 Share Posted January 5, 2016 A very good investment a balsa stripper. Strip balsa cost silly money compared to how much you can make yourself with a balsa stripper from a piece of sheet. BEB Quote Link to comment Share on other sites More sharing options...

john stones 1 - Moderator Posted January 6, 2016 Author Share Posted January 6, 2016 Cheers lads Not much to show you yet, I've fettled all the ribs I cut ready to start building a wing, it will be built in a slightly different order to Peters method but we'll end up with the same wing, only alteration is a fuzz mounted u/c, and i'll build wing as one and cut the ailerons out. Made a dihedral template, as you can see it's upside down, best remember when I fit the rib John Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted January 6, 2016 Author Share Posted January 6, 2016 Made a start with the glue, pinned some thick balsa on the plan outline to keep it all square, then off we go. Ribs are a good fit so only pinned the l/e strip, inner rib glued in using dihedral template, will cut for the brace when dry, glue all ribs up then add top spar, and leave to dry.

Craig Thomas Posted January 6, 2016 Share Posted January 6, 2016 I'm glad someone has mentioned the dihadral. There is no mention of it on the plan. Other than an Ince index each wing tip I think I read. So the inner spars of each half of the wing, whet angel should they be glued to the spars at? They can't be 90 otherwise the wing will be straight ? Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted January 6, 2016 Share Posted January 6, 2016 You build one wing completely. You leave the other wing pinned down and do not aaadd R-1 . You then take the completed wing and prop up the tip two inches and jioin it to the wing that is still pinned down with the dihedral brace. Then add R-1 and complete the leading edge sheet.

Craig Thomas Posted January 6, 2016 Share Posted January 6, 2016 I need to read my posts before I post them. My typing is shocking. Thank you Peter for that explanation on how to get the correct angle. I did wonder as it has not been mentioned yet, or if it has I must have missed it. 👍 Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted January 6, 2016 Author Share Posted January 6, 2016 I'll be slotting brace in later Craig so angled mine. John Quote Link to comment Share on other sites More sharing options...
Craig Thomas Posted January 6, 2016 Share Posted January 6, 2016 How do you get on with your slec stripper John? Im not so sure on it? It's a bit of a pain to adjust the cut width. Remove all 3 must to add/remove spacers. I've only used mine a couple of time at the moment and maybe need more time to get used to it. But at the moment I would say only 3 pot of every 5 cuts and accurate at the moment. I keep catching my fingers on the white plastic nuts as I make a cut. DOH ..................

john stones 1 - Moderator Posted January 6, 2016 Author Share Posted January 6, 2016 Don't press on to hard and it cuts o.k, you have to go over a few times though, and yes the adjusting's a pain, I like the looks of the Kavan/master airscrew ones.

Craig Thomas Posted January 6, 2016 Share Posted January 6, 2016 Yeah, they were one ones I was looking at before I bought the slec one. Look so much simpler. Not used the slec one that much. Have stuck the guide rail to a long piece of mdf. Takes up precious space now. Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted January 6, 2016 Author Share Posted January 6, 2016 One panel progressing, tomorrow i'll add the webs and sheet before lifting from the board. John Quote Link to comment Share on other sites More sharing options...
Chris Barlow Posted January 7, 2016 Share Posted January 7, 2016 The Kavan stripper is very handy for cutting the odd strip or short length but for full lengths and lots of cuts I prefer the Slec one. I have recently treated myself to a Slec building jig so will be mounting the Ali channel for the balsa stripper to one edge of it. The grid of the jig is stuck to an over sized piece of 3/4 ply leaving loads of room for the stripper and saving space in the workshop too!

Peter Miller Posted January 7, 2016 Share Posted January 7, 2016 I had a SLEC one years ago. Didn't like it and it took up too much space. I prefer the Master/Kavan ones but you do have to be carefull at the end of the cut as there is a tendancy to swing the stripper at the last momentwhich makes the last inch or two a little wider.

Frank Skilbeck Posted January 7, 2016 Share Posted January 7, 2016 These are brilliant for strip wood, especially if a friend has one and cuts is for you I'm thinking of a Ballerina for my next build, how do we think it would go on an old Vega 50 twin which would just fly a Flair Magnatilla.

AVC Posted January 7, 2016 Share Posted January 7, 2016 Hi John This building goes really well. I like the way in which you've built the tail. I'll resume my building on Friday. I can only spend weekend nights on building now... Quote Link to comment Share on other sites More sharing options...

My OS FS40 Surpass turns an 11X6 prop at around 10,000 rpm. If your Vega twin does roughly the same it will be fine. Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted January 7, 2016 Author Share Posted January 7, 2016 Cheers AVC No work for me the weather's stopping me, Only bit about the Slec one I don't like is the blade adjusting, for cutting strip with the other type, cut so far then turn balsa over and end for end ?

Biggles' Elder Brother - Moderator Posted January 7, 2016 Share Posted January 7, 2016 Interestingly you are building the wing the way I would. With it "packed up" in key places, then add the le sheeting after removing from the board. I notice that Peter suggests a slightly different approach - he puts the le sheeting down first, then adds the spars etc and finally the ribs. If I understand correctly he then glues the sheeting up onto the ribs while the assembly is still on the board. (Please feel free to correct me if I have misunderstood that Peter!). So the sheeting is effectively his packing during assembly. Pondering now, whether to stick with what I know - ie the way you have done it - or branch out and try something new!
