If you've never used contact cement before -
You apply the glue to both parts and let it dry. When the dried glue touches the other glued part, it grabs and holds strong.
There is a good reason why it is called "contact" cement.
A ring of contact cement is brushed on the pencil line.
Contact cement is applied to the edge of the support ring and allowed to dry.
Center the ring inside the pencil line and press into the hull.
Here the lower edge of the support ring is set and glued in place.
Apply contact cement to the upper edge of the support ring and inside the pencil line in the upper half.
Fit, press and join the two hull halves together adhering the support ring in place.
Held up to a light you can see the ring inside the round hull.
Run liquid plastic cement inside the overlapping joint.
Dip and push the brush into the seam as best as you can.
The contact cement won't damage the plastic, will it?
ReplyDeleteHi Bill,
DeleteIt doesn't really melt or distort the plastic. Weird stuff, amazing how it grabs after drying.
Centuri used to include it in kits that had vacu-form wraps, even up to the Saturn V.
Bill,
DeleteI should add, I wouldn't recommend contact cement for wraps like on the Saturn V. Spray adhesive allows for repositioning. Contact cement grabs and won't let go.
Thanks Chris, you read my mind. I was gonna use it on one of my Saturns.
DeleteBill,
DeleteI was surprised Centuri wanted to use contact cement on the Saturn V wraps. With the "instant grab" your chances of a good alignment after wrapping it around the tube is small. Once you adhere two pieces covered with contact cement, you can't lift it!
