Today started out frosty again but I got out there and did a session of grinding, got my fabric cut and commenced to laying up 8 plys. When closing out I sure wish I had cut some release film even if this stuff does not work well with VE resin. Still is better than working open fibers. Oh well, I do have 10 yards of peel ply on the way. But I am done for the day.
Next step will be fitting and shaping the core for the pad. Maybe by mid week I can be building that step.Regards,

I got a good step done today. With some final prep I got the pad cores bonded in place and started the final shaping of them.Here are the wood cores set in place.
This shot has the cores bonded in place, I used screws through the hull as well as weight to hold them. It took me some time to accept using screws but they allowed me accurate and repeatable placement.
The back of them is cut to allow the fiberglass to bond to the bottom of the hull,
And then the filler pieces will be bonded in place which will need minimal glasswork over them.
At the front end I am using a Microballon blend to build up the shape. This is just the first application. This gives me a more durable structure should the skin get breached, this reduces the chance for water to get in the core.
I did start final shaping of the cores but did not have my camera at hand so those pics later.Regards,

I am thinking the pad is going right to the transom but my approach allows for it to be short. I just have not made that decision yet and today might be when that needs to be decided.

Well, My CVX-20 Sprint now has a PadVee hull. It has been a long day, I still need to clean up but that will be after dinner.
Tomorrow, Friday I am taking a day off and my wife and I are going for a flight in a B-17. I need a day away.
Saturday I will be back to this. I will pull some of the peel ply. Shape the small bits of core at the stern and hopefully glass that area. I will also build a new transom water pickup since the previous one is no longer suitable.
There is some detail filling that needs to be done but unfortunately I might have to quit the work on this and get the hull upright and start reassembling the boat. For me time and materials are running out.Regards,
Charlie North

I am feeling the time crunch of customer deadlines looming. I have a big vintage car race meet late in the year which will eat most of my summer getting work done for.
As much as I want to finish this properly I will soon run the boat and get a baseline on handling and performance. I am hoping to get the shape of the reworked area as close as I can but I have run myself low on VE resin, I expect I have enough to mix a bunch of filler there are other areas I wanted to do glass work such as the underside of where the engine well was removed. Nice to get that done while the hull is upside down. By the time I restock this boat needs to float.
All trough this project I have been wishing I could mount this hull on my rotisserie but the way the hull extends aft of the structural transom make that impractical. At least my Superboat will have the benefit of the rotisserie when that hull gets worked on.Regards,
Charlie North

Wow , that's almost getting done. I didn't think you would do a full length pad , that will work well. I thought a delta pad,maybe 5 feet from the stern.

This pad should be better all around. Ultimate top speed is not my goal, wrong boat for that. But good rough water and moderately good speed is what I want.

Sure, that will work very well. I think the speed may surprise.

I am hoping or call it expecting that to be so. I have a bit more power now as well.

Nice work,but I think my old slow CVX20 will have to stay slow before I tear into something like that.
If I knew it was going to last this long I would have taken better care of it.

Chris, If the pad was done without removing the keel it would not be a bad job. The rough shaping of the wood core was not time consuming. I really wish I had chosen to infuse the core layup but I did not have a thin VE resin and had no intention to do this in the MAS epoxy.
Need to see just how this performs to see what the value really is.Regards,

Frustration today, This morning was below freezing so it was not an early start. Once I was working on this I got my prep work done, mixed my first batch of filler, got that spread, going for my next batch and discovered the bottom two inches of resin in the gallon can is jelly. Seal was broken on this can just last week. WTF?
There is no way I can get more resin here with the holiday since I only had three more days to make my goal.
Well my work is about 80% done, I knew I could not make it to 100% but I expected to get the fairing done.
Oh well, rest of today and tomorrow will be final sanding on what I can and the boat goes upright to be rigged.Regards,
Charlie North

What's the latest on this cool project? Adding a pad, going from a ProV 150 to an excel, very interesting to say the least!!!!!
