    Hi Guys

    As a Newbie I've been lurking around for a bit - but now I finally jump in:
    For the last couple of weeks I've experimenting with WS RTV moldings for for Tunnelportals and retaining walls. Seems to work outfine; but I was wondering if any of you have any experience with other RTV rubber than the one for Woodland Scenic ? Preferably something cheaper :)

    Regards from Scroodge KING_MEMPHIS

    molds

    I'm not sure what RTV stuff is, but if you, say, have a tunnel portal, and you want more of them, I used stuff from Hobby Lobby. Half a dozen or so coats and Voila! I think I got a half pint jar and have made several mold. Still have some left (if it hasn't dried up on me)

    Smooooth-ooon - sounds reeaally nice ! :-D

    Thanks for the welcome, Mikey. It's a great forum here.

    And thanks for the usefull links. Especially the Polytek- instructionvideo is great. It's fine to read about the process - but it's even finer to see it performed live. Though it seemed to be targeted to industrial purpose rather than making tunnelportals in Z-scale ;-)
    Well, if I downscale the process - it will probably work.

    Fine Hydrocal Castings by C. C. Crow - Availability and Price List - Model Railroad Structure Kits and Masonry Castings
    Hope this might help
