The mold section #1

So begins section one on making the mold.  For the mold I used isophalic resin due to it's strength and resilience.  The process begins with the buck having been sanded to a straight and flaw free condition before receiving 4 to 5 coats of wax.  At that point once the location of the dams (the areas where the mold will part) the area outside of the area to be covered is covered in tape to protect it for the next step.

Hot glue was then used to secure wood blocks to which foam strips are in turn glued to support the upcoming fiberglass layup.
If you look closely you will see small white buttons.  These are chair sliders and when the mold is made will produce "keys"  that will align the mold sections when they are assembled to form a complete mold


The area inside of the dams was then coated with "Part-all" before orange tooling gel-coat was applied followed by two layers of 3/4 oz fiberglass matt, two layers of 1 1/2 oz matt and finally two layers of 2 oz matt.  Additional 2 oz matt strips were placed at the joint from mold outer surface to strengthen.  


Next time....section TWO

Cheap work area expansion or the Taj Ma Tarp!

  Currently Gray Goats Rod and Custom works out of a modest 30 x 40 two car shop located on a piece of country property.  But this was not always the case.  The early years of the C buckets development took place in a VERY cramped single car garage.  The driveway was available on rain free days, but the southern sun can be brutal and I had to find an inexpensive solution.  Thus the Taj Ma Tarp was born.  A trip to Harbor Freight for a 12 x 12 tarp (I think it was 12x12 its been a while as I type this) with a stop at Home Depot for s couple lengths of electric conduit, a little rope and I was in business. Inside the garage door some screw in hooks I had laying around were screwed into the beam over the door to catch the grommets in the tarps edge.    Three equal length sections of conduit were cut and the ends compressed in a vice around a 16d nail with the head exposed.  This point is to go through the grommets on the corners of the tarp. Two...

Rear diagonals

I included this one just for fun, below are the main accomplishments for the day, rear diagonal braces. Oh and I set the body in place just for fun This was more challenging than it appears at first since the side rails are not at 90 degrees.  The bottom angle is 45 degrees, but the sides are not.  I just marked it and cut it close, then ground it to fit before tacking it in place.

Found treasure in Savanah

So my wife and I went on a long weekend to celebrate our anniversary and while cruising antique stores found this wheel.  I wanted something different/unique/cool for the C bucket and ran across this vintage boat wheel.   No idea yet what it was from, and I know I'll need to make an adaptor but the center is steel and the rim is mahogany.  Another project in the progress but it will be different :)
