Don't know if any of this is relevant to the discussion...these photos show the tissue seam used on my peanut S13...tissue attached using glustick...later doped after tissue applied to model.  Note:  The top photo shows the red tissue on the outside of the white...the bottom photo shows the white on the outside of the red...MY BAD!  Lesson...lighter color tissue to the inside of the seam...darker to the outside.  Be careful.  Smiley

Oh...seams have held up just fine so far.  Should add that tissue was spliced together and then applied to model...and spritzed...no problem with seam delaminating.

Hope I've contributed....

Looks good so far AK.  You are correct that overlapping templates are needed for complex curved or boxed joints.  When I've spliced tissue I've used full strength dope (no thinner).  I tape the pieces down over waxed paper, adjusting to get the edges flat with a consistent overlap.  Once I'm happy with alignment I'll apply dope along the seam using a fine brush, working from the center out to the edges of the joint line to reduce the chances of getting a pucker between the two pieces of tissue.  Let that dry, then flip the tissue over and paint another thin line of full-strength dope along the reverse side of the splice.

Haven't encountered any problems with spliced joints coming apart during tissue application, shrinking or doping.

Getting the overlapping tissue pieces had problems that I failed to see until now. A couple of pics should show what I mean.

The first pic represents a piece of tissue with the curved camo pattern in red. This will be the darker of the two pieces. The second pic shows the lighter color other piece of tissue with an overlap. The overlap is made by tracing the first outline on to the lighter tissue and then cutting that piece out with the overlap (the blue outline represents that).

Splicing Tissue Together

In the cook-up section, we had a discussion about how to get a camouflage pattern by splicing pieces of tissue together. Rather than clog up that discussion, I'll start it again here.

I began last night by joining two pieces of domestic tissue using dope. Here are some particulars.

1. I cut the tissue using the Xacto swivel blade designed to cut curved patterns. A sharp blade is important!

2. I placed the two pieces of tissue on top of each other and then put a piece of bond paper on top of that.

3. Hold the stack securely when cutting. I pinned the stack to the cutting board.

4. Then I painted a thin bead of dope along the curved edge. Waxed paper might help in avoiding stuck tissue.

5. You should be able to overlap the edges of the two pieces using an approx 1/16" overlap. Darker color on top. Pin this down securely.

6. Now apply a thin line of thinner along the doped edge. Avoid excess thinner as this may stain the tissue a little.

7. Let dry thoroughly.

8. Take care to note tissue grain direction before joining pieces. Also note if the tissue has a shiny and dull side.

Pictures show the slight dope overlap stains. Please disregard pin holes!! Pieces were about 3" square.
