Speaking of bolts . . .
I still have bad memories of 'galling' on some of the stainless steel fasteners when I did my extended swim platform on the Formula 330. It seems like the preferred solution to avoid galling is to use some anti-seize on the threads. Bolts/nuts are 316 stainless...
Speaking of pins and spacers . . . I made some adjustments to the 'pins' in order to make the installation easier and repeatable.
.
.
I ground the ends of the bolts to make them look/act more like pins. I also have them slightly loose to the have some play needed for the initial alignment...
@flashback , here is a diagram that I used to show the need for spacers to some folks on another forum ( some people . . . :rolleyes: ). Essentially, the beveled sides, as built, ended up being a 'tad' too wide for the transom. As such, the extension bracket would find itself off-center...
No there are (will be) spacers that are thicker than the nuts . . . The transoms of the boat & extension bracket do not come in contact. (the bevel sides interfere with the fit). Thus the hull & deck adhesive putty to fill the gap.
Installation Update . . .
I got the extension bracket aligned with the different (0.45") spacers. As such, I drilled the 'pilot' holes and put the 'installation guide pins' in at the 4 corners of the extension bracket. They will need a little bit of play in order to align with the matching...
The center stringer support is done. I do plan on putting in a floor of some sort to make for a decent storage area. The new stringer will play a role in supporting a floor.
I did another test fit and decided to go up a 'wee bit' on the spacers. (0.45" up from 0.35"). The thinner ones were...
The sun is shining so I'm doing some more glassing. I did the crossbar pieces over the past couple of days, and today I glassed the center stringer . . . 4 layers wet-on-wet.
.
.
With the sun out, temperatures in the boat are 80˚F, even though it is only 60˚F outside. To keep the coldness...
I took it @ 70. . . a while back I did a calculation of taking it earlier or waiting. There was about a 8-9 year break even point. Thereafter it is a gravy train.
I am glassing today . . . not quite warm enough, but I got a heater going and using 2.25% MEKP . . . seems to be working . . . but it is not quick. :ROFLMAO:
You wouldn't have tooling resin in a production piece. :unsure:
That (red) is the fiberglass (resin). Not sure what it is, but probably a VE resin. The VE resin I used on the extension bracket is more green in hue.
I am out of 40 grit disks, which was fine for today, as I can only do so much grinding in a day.
.
.
I'll be getting more 40 grit, because the underside of the swim deck needs some grinding . . . not the hole area, but where I want the contact points.
