S45 Construction - what happens when you use too much polyurethane glue

Picture #4 shows what happens when you use too much polyurethane glue. The squeezeout is unsightly. I used Gorilla Glue to attach the sides because it is flexible and it only needs to be spread on one side of the joint. It is much lighter than epoxy.

I used CA glue for the planking. First, kicker was sprayed on the plank. Then the plank was placed on the boat starting at one end. Thin CA was dribbled along the joint, and the plank was pressed against the next one. The pressing seemed to kick off the glue, which gave off smoke as it bonded. I continued this from back to front, one frame at a time, until the whole plank was attached.

Also shown is the hardwood chainplate support. I doubled it for strength. If I was thinking, I would have doubled on top, so it would help support the deck.

Dave, here are two photo's of how I aligned the keel tubes and rudder tube in my CPM hull.

With the pop of the starting gun, all hands flew into action. Rudders strained to tack sharply and get on the favored side of the racing course; sails were trimmed tight as a drum to eke every last iota of speed out of the wind; waves slammed into bows and washed clear over the decks. And as the fleet raced toward the first turning mark, the atmosphere intensified and nervous fingers grabbed the toggle switches for additional maneuvering.

Toggle switches?

Model yacht racing, or 'RC' racing (for 'radio controlled') is what gets many boaters through the winter. It keeps the adrenaline flowing from the thrill of competition, albeit on a small scale. But, like boating, it offers camaraderie and fun that's easily accessible to anyone with working fingers and enough charged up AA batteries for an afternoon of sailing.

Thinking small is easier on the bank account as well. The outlay for a ready-to-sail RC boat is usually in the hundreds of dollars, not thousands. Access to the water is as simple to find as a quiet pond at a local park. Some cities have even built special yacht racing ponds, such as San Diego, because it's such an eye-catching attraction.

'Model racing is less of a commitment in terms of time as well as money,' said Dick Rutledge, a BoatU.S. member from Houston who is also the national vice president of the American Model Yacht Association (AMYA), the all-volunteer organization which sanctions classes of RC boats and all official races. 'I can have my model loaded and on the water in 20 minutes.'

Rutledge and his wife Nancy are avid racers on Lake Conroe in Texas and compete in their full-sized 'people boat,' a Ranger 22. One day at the dock, one of their Ranger class friends was playing with a model yacht and handed the control box to Rutledge. 'I was hooked,' he said, and now travels throughout the U.S. to compete in the Star 45 and 36/600 class races. His wife is a top competitor as well. The Rutledges also belong to the Houston Model Yacht Club, one of 120 in the U.S. that organize local races."

The Fundamentals of Fiberglass - Fibre Glast Developments

The Fundamentals of Fiberglass - Fibre Glast Developments: "Worksheet For Estimating Materials

1) Begin by calculating the surface area of the project. Estimate irregular shapes by measuring the approximate sized rectangles necessary to contain the tapered areas. Multiply the length times the width for each rectangle, and then add all of individual rectangles together to get the total surface area of the part. If the calculation is in square feet, divide by 9 to get square yards.

2) Make a list of each type of reinforcement being considered for the lamination. Multiply the square yards calculated above times the ounce weight of the fabric. This is the total weight of one layer of that material. It is also the amount of resin required to saturate it. When this is known for two or three different types of materials, it is possible to calculate the weight and cost of a laminate constructed from any combination of these fabrics. To convert the ounce weight to pounds, divide by 16. Those inexperienced in saturating fiberglass tend to use far too much resin. A well saturated laminate is uniformly translucent, without milky appearing dry spots, but for the sake of weight and cost, has little excess resin in it."

The Fundamentals of Fiberglass - Fibre Glass Developments: "Estimating Material Weights And Cost

Accurate material estimates are necessary for two reasons.First, they obviously are needed for proper ordering, material stocking, and bidding of projects. More importantly though, estimates offer the opportunity to calculate the weight or cost of the part using a variety of laminating schedules before beginning to build.

Unlike estimating coverage when painting, resin usage will vary depending on the type of reinforcement being used. The heavier the fabric, the more resin it will take to wet it out. A good hand laminate consists of about 50% fabric and 50% resin by weight. For example, if an application requires 3 sq yds of a 4 oz/sq yd fabric (total fabric weight = 12 ounces), 12 oz of resin will also be needed. However, if 3 yards of 10 oz/sq yd fabric is chosen (total fabric weight = 30 ounces), 30 oz. of resin will be needed.

Glass mat requires a minimum of 2 ounces of resin for each ounce of mat. Therefore, it the application calls for 20 sq feet of 1-1/2 oz/sq ft mat, it will require a minimum of 60 ounces of resin. Remember that mat is specified in ounces per square foot, where fabrics are specified in ounces per square yard. 1-1/2 oz/ sq ft chopped mat actually weighs 13.5 oz/ sq yd!

Since there are so many possible combinations of materials, one should calculate the weight and cost of a single layer using a variety of reinforcements. These can then be added or subtracted form the theoretical laminate until the design properties are achieved."

The Big Day!! Star 45 Launch

From: John Whiteford


G'day ,
Great morning yesterday when we launched Oribi tho for the first time for some time the weather was overcast and the wind fickle. However all went well and she looked pretty good and some good comments from the few members there. Had a couple of nice gusts which pushed her along and she went well, so looking forward to next time. Took heaps of photos and attach the best here. Must qualify the CHRISTENING!! The phial in Julia's hand contains red wine which she rubbed over the bow with her finger....not allowed to take alcohol into this park!! So I drank the rest last night!!!!! Also please note the cap in PROUD OWNERS. I got quite a few comments re this!!! and stirred them up!!! I was wondering if any of these should be placed on the Star45 website and where. If you think so would you be kind enough to copy them there for me please Don. Also thanks for the advice on the bow bumper and will sort something out along that idea.
Kind regards,
John
