john: the discussion has been about the M15. a quote below from jerryM dave scobie M15 #288 - SCRED visit Scred's www-site: http://www.freewebs.com/m15-named-sced quoting jerryM- jerry@jerrymontgomery.org I think this is all documented in the archives. I originally tooled the 15 for an exact fit for the PP35. vA few years later Thetford dropped the 35, replacing it with the 135. I bought all the 35's that I could find in the pipeline, and when they ran out I retooled the mold to fit the 135. I have fit 135's to the 35 bases using a hair dryer, and others have done it using hot water. In both cases patience and a beer in hand are helpful. jerry --- On Tue, 4/21/09, John Ledger <johnledger@aoi.org> wrote: Does anyone know if this method works for a M15?
