Re: Formula 15 Renovation
Cheers. I’m about 13 hours into wet sanding it with 400 grit. Another 3 hours or so then onto 600 grit and I’ll rub down all the last of the orange peel then the fun begins. 1200grit and polish.
Hopefully get it knocked over this week and onto fitout next weekend.

Re: Formula 15 Renovation
What an achievement Ducky. I'm still a bit concerned about the the balance with that big 115 on the back, but keep us posted.
Cheers, Col.
Re: Formula 15 Renovation
I am in awe of all the work you have done, your boat is looking very nice. It may be a bit of an excitement machine to drive, love to hear how it goes.

Re: Formula 15 Renovation
I am very keen to see how it goes. Lots of thought has gone into the placement of weight to offset the motor @174kg.
The previous motor was 113kg and the boat sat pretty well with electric motor and agm up front. 25l fuel and ~25kg battery plus outboard up back.
This will be setup as 100l fuel on centreline/forward. Battery on centre line. Nothing up the back except for the outboard. And 16kg lithium + motorguide + anchor winch up the front.

Re: Formula 15 Renovation
Well done, looks awesome. 50 hours of sanding is crazy, what an absolute grind that would have been.

Re: Formula 15 Renovation
It sucked man.
I weighed up the risk v reward of power tools at the beginning vs the risk of rub throughs. I hand sanded way more than I would if I were to do it again. Could probably do it in sub 30 hours if I were to do it again by using the orbital and 1/3rd sheet sander a hell of a lot more. I just really don’t ever want to hahaha

Bloke who did the gelcoat “here I’ll show you how to wet dry cos you really don’t want to rub through this ****. Here’s 600 grit. Rub wipe rinse repeat. In the bad spots use 400”
A day later I’m wet rubbing. Started at 600. Spent 20 mins in a small spot on the transom. Went through 2 sheets. Still plenty of orange peel left. Gave it the arse. Went to 400. Spent the rest of the night doing that. Was painful but made progress
Next day spent a whole day with 320grit on the top of the gunnel and inside and rubbed until the smallest bit of peel was left thinking that was a good idea to progress to 600 for final removal. Tested that out. Was a **** idea. Took way too long.
Next day i grabbed the orbital and 240 grit and skimmed the whole boat taking off the worst of the peel. Then decided to finish the concave angle to 600 with no peel to work out how far I need to push it. That took hours by hand but I finally learnt how to finish it. Once it was done I smashed out the 1/3rd sheet with 180 on all the flats because it gave a flatter smoother finish than the orbital.
I think the well took about 10 hours by hand because I couldn’t get power tools in there.
There was a shitload of rework because as the finish got smoother you could see more dimples etc when lit up sideways.
If I were to do it again I’d hit it with the orbital all over with 180-240. Then 1/3rd sheet up to 600 and hand sand once all that was done. Not to mention I’d be a lot more brutal with the belt sander getting the transom dead flat prior to gelcoat. It has a couple minor high and low spots due to the clamps when bogging in the new transom timber. Barely noticeable but a pain if you’re blocking.
The joys of learning how to do something eh. I reckon I’m up to about 200 man hours just straight up wasted on **** done in inefficient ways because I didn’t know any better at the time. Or on work just thrown in the bin because the end result looked **** due to the above. Not that I’m in a rush to do another one but god damn it would be a helluva lot quicker.
Also I’ll leave you with a little teaser of the ridiculously over engineered hose clamp I’ve drawn up and got cnc’d on berleypro’s new 5 axis.
