Batter Up Build Part 8 Contact Cement and Fins




After the fins are dry, the overhanging balsa was trimmed off.






Here's the fins ready for gluing.
I'll be using contact cement to glue the fins to the plastic bat handle.
If you've never used contact cement be ready for a quick grab!

Contact cement is applied to both surfaces being joined. In this model, the glue tabs on the fins and on the bat handle.
Wait for the glue to thoroughly dry on both parts being joined.

Even though the glue is dry to the touch, when both parts are joined, you'll get a bond that is hard to pull apart!
Be sure your fin is aligned before allowing both glued surfaces to touch.
This contact cement is pretty old and brown. When new it is a lighter yellow color.

Using the brush on the glue bottle cap, it was applied to the tab flap of the fins.
A wide line of glue was also brushed on the fin lines drawn on the bat handle.
Try to keep control of the cement, it'll want to go everywhere!

It does clean up easily so don't worry about any extra strings of glue on the surfaces.
