    Like a hot knife through butter

    Wonder if one could use one of these in cutting the Bronco Type XXIII.

    Bob showed something similar in one of his recent YT videos.

    Might be OK for a short cut, but a long cut like the XXIII? I’d say no.

      My approach in cutting the Bronco would be:

      Put the hull on the keel ans secure it in place (e.g. with pieces of wood that are hot-glued to the base plate. Then you make two identical templates of the cut out of wood and position them correctly left and right of the hull. Then use a cutting wire (0,25 mm) and make the cut using the templates as guides.

        Nice idea about the box or trough that hold the hull snugly with the top of the two side walls at the level of the hull cut.

          Carefully using a razor saw, just under a horizontal molded weld line can provide very good results. Tedious, yes, but quite satisfactory end result. I also used this method on my 1:72 Gato. A tiny bit of sanding and CA build up on any kerf booger and you're golden!

            I hear Dave Merriman uses his laser vision to cut hulls...or a Dremel wheel, I forget...

              I have Pfrozen's Beam Cure which is excellent - especially when UV-curing putty and resin applied to seams. The light will easily penetrate a 3mm thick hull.

              I passed on their next product, the Sonic Sabre which is designed to cut through small resin supports, not plastic. Nice for miniatures, but I have other hand tools that do the same job for a lot less.
              YMMV.

                You better watch that. David doesn’t like his secret superpowers being talked about.

                  Id mark the cutting line with a pen and a ruler and use a japan saw/razor saw. Heat/ that vibro-blade etc ruins the styrene hull in my experience. A sharp hobby knife along a steel ruler might work, too.

                    If I had to make that cut I would use one of these... They're made by various manufacturers I have a Dremel- I use it for everything... It does plunge cuts and will follow a straight line almost all by itself... Fiberglass, plastic and wood no problem...

                      Well, Logan and I just checked, and our ultrasonic knife sliced through the styrene hull of a skipjack kit like butter, leaving the tiniest kerf and a perfectly straight line. I video'd the process and it will be included in my next update video posting this weekend, but until then, take my word for it, this is DEFINITELY the way to cut a hull....

                          How do you think this would work cutting a fiberglass hull?
                          Now if you'll excuse me, I'm going to go on an overnight drunk, and in 10 days I'm going to set out to find the shark that ate my friend and destroy it. Anyone who wants to tag along is more than welcome.

                            Bob, can you post a picture of the product and where you got it? I hope it’s not the one on Amazon for 1200 bucks.
