Bert's Vacuum Bag & Other Documents Here, Thanks to Oneula

I had the Oneula Bert Berger vacuum bag/forming, sandwich construction and other miscellaneous Berger files saved too. Oneula saved them as MS Word files. It is easy to convert Word files to PDF Files. The new forum format allows PDF attachments. I converted the Berger files to PDF and attached them to this post. I did the same with Oneula’s Barnfield files too. Anybody should be able to download them from this thread now. “Onward Thru the Fog.”
