    Daniel, nice craftsmanship and very inventive! Yes! That is what I was thinking: to trim down some other board and attach the salvage remnant to a Crowb board. Did you tap and thread the holes, or drill a pilot and let the screw grip? Or small small screws/bolts with nuts? Knowing exactly what screws yu use would be a great help. Thanks!

    Another possibility for you, are these anodized screw-together metal tubes (made in China). $20 each they are advertised on Ebay as for "Wista", but I modify mine to fit Plaubel Peco Jr. Nicely made and not too expensive, either. Come in three different lengths, your choice. I have quite a few of these, I keep reordering them as I need them. I lined this tube set with flocking paper from Edmund Scientific.

    Shown ^^: 360mm F11 Kern-Arau dialyte on Plaubel Peco Jr board (No; It's not heavy at all. A lightweight set).

    You can also see how I trimmed down the original Wista board (also $20) with my power scroll saw and attached that to the Plaubel board, again using teeny tiny modeling brass screws from the local hobby shop.

    I bought an assortment of sizes, these are all usuable depending on what you are fabricating. Google "hobby modeling screws" and there are plenty of sources.
    I use a mini drill press to drill the holes through the cone and the board, then use nuts and screws to hold it all together. I even use some stuff I bought at the local Home Depot in the hardware department. It's not that critical. Flat back spray krylon (sprayed onto a cardboard and applied by brush) is your friend.

    Daniel,

    Thanks for the additional detail. I love improvising and using found materials, so this approach appeals to me greatly.

    I’m now trying to determine how long of a tube I can use and have another thread posing the problem.

    Many thanks,
    Paul
