    Scott T - Revell Gato 1/72 Build

    Glued up the boat stand. Used a clamp from Harbor Freight.

    The flood holes were drilled with a brad point drill bit and hand drill. You can see the outline it leaves.
    You can only drill completely through on one hole. Then clean the other part of the opening with a Dremel (4000) tool with a guide point roto-zip bit.
    Since the hull was not glued together I could shove the bit up from the bottom \ inside hull and be able to see the material I was removing.
    Being able to slow the Dremel tool down in speed made it possible to use this bit.
    Some openings are great and then some are not so great.

    Cut the template up for the flood holes and folded over the edge. Taped down with scotch tape.
    Numbered the paper and hull with the same number 1 thru 12 I think.
    They fit well between the weld lines on the hull.
    Took a drill bit in a pin vise and drilled holes on the center marks.

    Cut the ends off with a saw from Hobby Lobby.
    If you take my friend with you to Hobby Lobby you can get his employee discount on purchases, there.
    If I remember right the model was around $90.00 and the discount made it around $70.00.
    Not sure how many years ago that was.

    This is where the drastic surgery on the hull takes place - opening the upper hull.
    Cut the vertical cuts with the saw. Then cut the horizontal cuts with an X-acto knife by dragging the back of the blade.
    It scrapes a curl of plastic with each pull. I tried to count the number of strokes and guess somewhere around sixty plus
    to break through the thick plastic. Not fast but kind of soothing to watch the curls come off.
    For the first (easy) part with the pins I let the knife follow the intersection of the curved and flat surface.
    I should have not cut the cross joint connection pin pocket off. We will see how strong it is after the glue dries.
    I had previously taped the hull and decks together and made a pencil mark that can just be seen in the picture to help
    judge what I wanted to cut out. All these steps can be found in other builders build logs. Nothing new under the Sun.

    I used the front piece I cut off and taped it to the rear for a guide. This worked well as a guide.

    For the middle section I leaned the blade against the flat vertical surface to guide the cuts.
    The blade wandered on me a little, but it looks pretty good. Stuck the pillow in the boat to
    help prop the hull while cutting.

    It took a while of figuring (reading others builders work) and getting the nerve to cut into the boat.
    Something has been accomplished here but not completed.
    The width of the opening is around 2 ¾” so I think I am good there.
    The building Journey continues after a long stop.

    Whoo-hoo! Way to go Scott. I am so glad to see you moving forward with the Gato and look forward to your style for putting this together! I am going to enjoy this sir!
    If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

      So I did a little scribing with the back tip of the knife blade. Makes a square slot instead of a v shaped slot.
      Clamped my deck on edge with mini bar clamps.

      Scribed lines on the sides with the limber holes. Cut the 4th hand\foot hole before gluing.
      Used the grinder for the top arc and saw and knife for the bottom notch.

      Made pins to connect side pieces from pieces of sprue. Used a drill and file to fit piece for hole size.
      Found the close pin worked to keep the support block from walking away on me.

      Used a compass to mark the center line on the bulkhead piece; then again to mark the cut out for the Water Tight Compartment.
      Used the back edge of the blade to scribe and cut through the crescent shape.
      I left a 1/4" for ballast space. Not sure what space other modelers used.

      Glued the hull together. Tape on the outside and mini bar clamp on the deck side. I used clothes pins in the flood holes for clamping.
      With the hull top open it made gluing easier. Did not glue the bulkheads as I want to remove and finish cutting them for the WTC support.

      Tools from the Dollar Tree. Each a dollar tape, knifes, and scrapers. Alot of knifes for a dollar. 13 x 3 = 39 blades.

          Previously opened the torpedo doors. Thinning the edges around the openings with a power tool and then the jewelers file.

          Glued the limber hole side pieces together\ sides to middle deck piece \ bow to middle deck \ sides to bow.

          It probably would have been easier to glue the bow and middle deck pieces together first and then glue on the side pieces
          followed by the cross bars.

            Scott, what is your plan for attaching the deck to the hull? Are you going to cut mid-line or have the deck open?

              The top of the hull is already gone with a little over 2 1/2" opening. I will take a measured picture next post. My plan is to have the bow
              attached to the upper deck like a z cut hull. I have seen Pictures of Gene Bergers model done similarly. I would post a picture but it is in
              the old computer that died.
              Tom thanks for posting RCSUBS as they have some amazing etched brass decks.

                that's where I got the photoetch for my Arkmodel Type VII. it's actually somewhat overwhelming how much PE you can add to your model.

                  I just reviewed your photos. I see what you have done. I look forward to your next step. You are doing really clean work Scott!

                    Using the retractable knife blade lets you mark close enough lines on the pattern for the door openings.

                    Used a saw to make a slot in the limber hole box to hold the back wall of the openings in the center of the hull.

                    Cut paper patterns to make floor surface in the openings. Later cut them in half to glue to back wall.

                    They were left a little long to have something to hold on to as I test fit the floor pieces.

                    I did not take a measured picture of the hull opening. Maybe later.

                      Scott, what is next on your to-do on this sub?

                        I am working at the front torpedo tubes and doors. I want the doors to open and look close to right.
                        You know how your exhaust diffuser took 5 months ...
                        Model work area was cleaned off so we could have a valentine dinner.
                        Some ship lap siding had to go on the wall. This has given time to think about the model some more.
                        Hope your shoulder heals and the doctors do an amazing job.

                          Scott,
                          This is your first sub correct?
                          If I may make a suggestion, do not get bogged down with fancy stuff. Get your sub working. Once that is under your belt, then go crazy! You might remember, I got my Gato running, then put lights on and other fun stuff, but it was running first.
                          If it is your desire to get the doors working, then go for it.
                          Peace,
                          Tom
