I figured there just may be a slim chance of having one or two more days left in the year peaking above the 65 degrees would I needed for one more day of fiberglassing. I had waited a little longer before cleaning up around the Batboat and putting things away for the winter.
One of those last warm days dawned on Saturday, October 11. I was checking with Weather.com every day and it finally predicted that the weekend was going to warm up so I made plans for the last fiberglassing of the year.
What I wanted to do was more transom work with what little polyester resin was remaining and start on the Shark, Whale, Manta-Ray and Barracuda Marine Repellent cans.
Anticipating this day, I added one more item to my arsenal; a stainless steel electric mixer spindle. I got this handy tip from Oops! at the iboats.com forum's Boat Restoration and Building section. These are used on a drill to blend fiberglass resin more efficiently with its hardening catalyst and also with thickening agents like wood flower and cabosil.
I found a myriad of them at the Salvation Army. This was the longest one they had and it was priced around $.55.
I didn't have more than 3 quarts of polyester resin left so I set out to fill in and smooth out the low areas of the transom inside the boat and also a part of the transom plywood that would hold standing water.
I organized all the tools and everything else I needed for the work that morning and had it all ready, however, condensation and morning dew doesn't dry up and disappear until after 12 noon. That gave me a lot of time to think things over.
As you can see, they are low spots in the fiberglass need to be filled it. If left the way they are, there will be air gaps between the hull and the new transom plywood after I laminate the plywood in. This is where the motor goes. Structural weak points.
The best way to fill in and smooth these out is with "Peanut Butter", a mixture of polyester resin, wood flower and cabosil, then grind it down flat after it sets. Called "peanut butter" because it has similar looks and consistency.
I forget what I used and how much of it but if I recall correctly it was one pint of polyester resin with a little more catalyst than needed, two handfuls of wood flower and one of cabosil.
First, I mixed the polyester resin with catalyst for one minute with the mixer then added the wood flower and cabosil until it was all blended in.
This was the first time I ever made this and was worried that the Peanut Butter would begin to harden before I could use it all up. The opposite happened because it took longer to set than without the thickeners.
The Peanut Butter I made was more like a thick pudding but it still worked great. With my spackling knife I glopped the mixture into all the uneven spots on the boat's transom area. Some of it had to be worked it back up after oozing down but in the warm sun it started to solidify enough so I quickly turned to the transom plywood.
Here is a potential problem area on the new transom ply I made. A shape had to be cut into it to allow room for the splashwell. This will be laminated into the Batboats transom which leans back about 15 degrees creating a pocket where water can collect and sit, eventually cause rot. The solution is to fill it all in at an angle.
I used a Lowe's paint stirring stick I found in their parking lot as a trowel on the thickened poly resin
It wasn't as thick as I needed it to be and, as a result, was difficult at first to get all the Peanut Butter to stay in place. However, as the minutes passed the mixture began to jell stiffer making it easier to keep its shape.
After I glopped as many layers on as I could I quickly spackled the rest of the mixture to the already curing areas inside the boat.
There were also several dowels that were loose in the ply so I pulled them out, filled the holes in with Peanut Butter and hammered them back in.
The dowels fill in where the later removed wood screws were used to clamp the two pieces of transom plywood together.
While I was waiting for all this resin to harden I grown down the already solid dowels flush to the plywood surface and took a break.
Thickened "Peanut Butter" polyester resin hardening in the warm sun
Every area I filled in had cured completely solid. Its time to grind it all down smooth so I can laminate 1.5 oz chopped mat strand cloth on it.
the grinder made everything nice and smooth
All low spots are completely filled in. Rough spots ground smooth. I cleaned the resin dust off the ply with a rag shirt soaked with Acetone and let it evaporate. Its ready for fiberglass cloth.
Here is one of the pattern shapes I cut weeks before. I am going to laminate this to the transom plywood to make it water proof. But first I need to cut out the spashwell area so I can lay that in easier. I mixed up a pint of resin and wetted on a thick layer with a paint brush to the ply so the fiberglass cloth will soak it in good.
fiberglass cloth roller
The picture above is the tool you'll need to work out all the air bubbles out of, and work resin into, the fiberglass cloth.
Air pockets are weak spots in lamination. The little ridges are key to working the resin in and bubbles out.
It was put to good use today because I had a lot of problems with the cloth not laying flat along the curves and edges of the splash well area but as the resin started to jell it worked out great.
I have two rollers, one that is big for the larger areas and a smaller one for tight spots. I think I used both on this day.
After the transom plywood was wet down with resin I laid the fiberglass cloth on top and quickly worked it down with the roller, alternately spreading more resin thickly on top. I didn't have enough mixed and hastily made a couple more pints to spread on while working out the bubbles, making sure that the fiberglass was saturated and laminating completely in contact with all curved surfaces.
By this time my hands were sticking to everything and strands of fiberglass were everywhere. Yep, I went without the gloves this time because they had become covered with sticky fiberglass strands making it impossible to do anything in them.
Later, I found the glass was easier to get off my skin than the gloves and didn't burn at all. Even got some in my wounded finger!
Top surface is now completely water proof. The other side gets fiberglassed next year when it is installed in the Batboat. I didn't have enough time or polyester resin left to do both sides. Ordering more would have taken five business days for delivery and by then who would know what the weather would be like?
While the finished fiberglass job was setting I began to grind the inside transom smooth and it turned out perfect!
I started clean up and also the task trying to get all the fiberglass strands off my hands, tools and everything else it stuck to, then took a break.
After admiring the way everything turned out so well I started to make the Marine Repellent cans but I will save that subject for later, along with my utility belt project, with its own blog section.
the real deals....compared with....my repellents shown here halfway through painting
With all of that day's progress and momentum it was disheartening after I tried to think a way around two major problems;  The amount of time it would take for a new polyester resin shipment to arrive if I ordered more so I can complete the hull's transom repair and  the unpredictable weather.
I knew the weather was going to be too cold so I didn't risk ordering more the weeks before. Today's work was done in Michigan unpredictable fall months. You'll never know how it is outside from one day to another.
Which would have come first? If I ordered four gallons would it arrive before or after the temp dropped below curing temp?
With regret and some frustration I realized again what I had known for more than a couple of weeks. I was through for the year.
If there were just three or four more days of good weather after the resin arrived I could be finished with the transom and may even have the stringers glassed in. If not, I would be stuck with expensive chemicals ($37+ per gallon) that may jell before I have the chance to use them next spring.
There is where I am at with the Batboat project.
It is completely snug under the tarp as I put plans away for the spring weather. All the plywood, tools, and nearly twice the amount of various fiberglass cloths needed is here and ready to go, too. :)
Boat Motor Rack plan and an example of a rack that I found online
The outdoor temperature had been dropping significantly at this point. Any further fiberglassing on the Batboat this year was out of the question. There was one last project I had left to work on; the Batboat outboard motor rack.
Someone posted plans for one of these a while back at the Fiberglassics site. I used that print out, a handful of wood screws I had salvaged from the Batboat fin, a bag of old nails, and some pallet and ply wood I've had for over 8 - 10 years.
I knew those nails, screws and wood I saved would come in handy some day.

Ready to get started!
This was one of the longest days I worked for the Batboat. It took more time than I thought it would to build this motor rack. I started out late in the afternoon and finished at dusk. It was very nippy and damp outside all that time. This needed to be done because I wanted to move the motor off of the porch and it was suppose to rain at any time that night.
The old plywood covered with red carpet pictured above came from a renovation I was hired for at the Midland Mall Sears store's "Tool Territory" back in the summer of 2000. High quality stuff so I asked if I could keep it.
I also joined the wood frame together for added strength rather than just nail it together
I have no idea where I got the wood that I built the frame out of but it is some kind of hard wood that is very difficult to saw through and nail into. 4 inch by 4 inch square by 5 foot long, or so. These used to be side supports for banded pallets and I got them for free, too. Must have brought those home from one of the many low paying temp service, slum sweat shops I used to work for long ago and prefer to keep those times a distant memory. At least I got some free, but high quality wood out of it all.
This stuff was heavy and did not cut easy at all. The result was an exceptionally solid rack.
Cutting the support sections
That was also the first time I used the table saw since I cut the tip of my finger off. I double checked and made sure everything was safe every time I turned it on and was extra cautious while cutting. I'm glad to say that as a result there were no more accidents.
Plywood has been cut to shape and ready to be nailed to the rack
The plywood was 1/2 inch thick and instead of just nailing it to the rack, I joined it by removing 1/2 inch into the frame, same as the height of the ply, then nailed it in. I figured this would give the rack more stability and strength.
Diagonal and bottom width supports are nailed in place.
This surely will hold much more weight than that of the 125+ pound motor I have
I'd like to make this a movable rack and looking around a week or two later I found four lawnmower wheels in the shed but the 125+ pound motor may wreck them. They are plastic.
As of this writing I'm still looking for a small kids bike with inflated tires to add to this. I can't see paying $30 or more for new casters considering everything else I used was free. Until then, the motor still is leaning on the porch.
The two above photos show the finished product, sans wheels. It was dusk and the camera's flash was needed.
Freezing cold out, too, but I kept on working until I was done. Rain began to fall as I nailed in the last two stubborn nails. This project had to be finished that evening or I may not be able to finish it until who knows when because Michigan winter had finally arrived.
We can't get enough of boats that have fins and eyes.
This Cool Picture Of The Week is of a restored Vali IV.
Manufactured in Coldwater, Michigan briefly in the late 1950s there are less than 15 known to exist. Not much is known about the short lived Vali company except they made only one boat design with different variations.
No, Woodflower and Funnoodles are not recipe ingredients. I'm using them on the Batboat.
On October 5th, I drove back from Bay City where I found swimming pool foam Funnoodles clearance priced at $1 each. I stuffed all fifteen in the back seat. Holy blind spot!
These are commonly used for foam flotation in fiberglass boat restoration. The material is the same used in aircraft wings and will not absorb water. They do chemically break down and shed to foam flakes if exposed to UV rays for too long but since they'll go under the boat's deck that will never happen.
An example I found on my hard drive of someones Funnoodle placement between the deck and hull. These keep the boat afloat if there is an accident on the water.
Each is around 5 foot tall, easy to cut and will fit perfectly under the deck of my boat.
I found two types of them. Ten are the standard, funtastic noodles and five Monster sized, both for ages 5+.
Friday, the day before this, UPS delivered two 2 1/2 lb. tubs (5 qts. volume) of Wood Flower to my door. Basically, this is expensive, fine saw dust at $9.50 per tub.
It is most commonly used to thicken fiberglass resin to a peanut-butter like consistency for filling inside corners, fixing holes and setting stringers to the hull, to name a few. Wood flour makes a great, coarse fiberglass structural putty, too. This and cabosil are indispensable in fiberglass boat restoration.
I have all the things I need now to install the transom, stringers and deck except for warm weather. Fiberglass resin needs consistent temperatures at least around 65 degrees to properly solidify. A garage and a space heater sure would come in handy right now.
The weather was cold and damp since the day I had the Batboat in the river, however, the weather report for today was good so I got up early to grind out most of the remaining fiberglass that anchored the stringers to the hull.
Perhaps I would have a few good, warm days until snowfall that will let me glass in the stringers, I hoped.
The old stinger fiberglass needed to be ground down a little bit to clean up what was left of dirt, rot and mold which the old, saturated foam floatation left behind so new fiberglass resin can stick and set to the hull better.
I put on the sloppy t-shirt, baggy sweat pants, overalls, Tyvek suit, and respirator again and commenced grinding with a 60 grit flapper disc.
It was damp and breezy but those layers kept me warm.
I removed all the original fiberglass foundations of the stringers except for two spots. I left those in so one stringer can brace the rest in place while I properly fiberglass them in. When the resin is set I'll grind down the remaining old glass and laminate in the last stringer.
After maybe two hours I felt light rain sprinkling down so I got out of the boat, began tidying up around the drive way, tarped the vessel, and put all the tools and equipment away for the day.
Geesh! What a disappointment. I was only a little more than half way finished!
Several hours later the sun was out and clouds mostly gone. Go figure.
Winter snow will soon be here. I will have to put most of my plans on hold until the warm weather breaks in June 2009.
