Also remember that the thickness of these webs will affect the spacing of the WAFs as they slide into each other for wing attachment.

This all makes perfect sense, but, I have read, re-read, and re-re-read this portion of the plans and this detail is not specified anywhere. Thank God for builders forums, eh?

> This all makes perfect sense, but.. Yep, draw it out full scale to ensure that your inner and outer WAFS will intersect properly. It may be that the short webs serve to provide both proper spacing and load spread about the bolts. My outer caps were slightly oversize (only a 1/16" or so) and I had a devil of a time getting their WAFS to slide inside the innner ones.

KR>new KR builder - spar question
Hello, Ok, so I've wanted to build a KR-1 since October, 1974 (yes, I still have the magazine) and I just now got around to ordering the plans. They have arrived and I am carefully reading the assembly instructions, trying to visualize this project. Step 4.2.10 includes this note: "the front spars have web full length only on the aft face. The aft spars have web full length only on the forward face." Huh? The accompanying drawings make no indication of this, and, if indeed this is the case, where does the web stop? Do other builders do this? Or, is this, like Monnett's "weight saving" spar holes in the Sonerii, advice best ignored? Should the web be full length of the spar on both faces? Thanks in advance. I'm sure I will have many more questions in the comming months and years. Keith C. Krumwiede Rosedale, IN

keith what you read is correct. You get a full web on the rear face of the forward spar and a full web on the forward face of the rear spar (outer wings). You also get a web on the front face of the front spar for the first 12" only. and you get a web on the back of the rear spar for 12" only. You don't need that extra web it only adds weight Mike Turner - Original Message - From: red-bri...@juno.com To: kr...@mylist.net Sent: Wednesday, August 20, 2003 11:57 AM Subject: KR>new KR builder - spar question Hello, Ok, so I've wanted to build a KR-1 since October, 1974 (yes, I still have the magazine) and I just now got around to ordering the plans.

Thanks, Mike. The plans did not make this clear. Were I already building, I'd be starting on effort no. 2. (I know. I wouldn't be the first.) I've already learned a great deal from this and other KR sites. Keith C. Krumwiede
KR>new KR builder - spar question
Keith, you need to read the plans and manual very carefully and then read them again. It's the little things that'll get you. For example be carefull to run the grain of the plywood vertical not horz. for the spars. It makes a difference!
