RickK's 170 rebuild

[RickK]

I think it is ready
Everything is faired down to 180 grit. (Still on the first sheet of everything)


I used an air DA to sand the hullsides (Imron) with 220 grit.








I did find some dings in the hull that I filled and will have to fair those spots but otherwise it's ready for primer.

I know, I know, you're saying to yourself "Rick it looks the same as it has for the past month or so" - I can say that at 50 feet it looks the same but at 5 feet it looks and feels good.

Looking great Rick! Fantastic job!
I will be focusing on my center console tonight. Prepping it for paint. I have given up on trying to do gelcoat repairs. It's just not possible without coating the hole thing...
I will put polyurethane paint on it.
 

Keep up the good work!

Nice Rick!  That's got to be a great feeling!

[RickK]

Thanks Lars and Craig - it'll feel better once it's primed.  Man was it hot out there in the afternoon - smmmooookin' hot.

Nice work Rick.......hope to start on the fairing out and hull prep on my 196 soon. Ever decide on the paint?......so many options.

I have not finalized the top coat.
I have purchased the epoxy primer so I'll do this first and then worry about the topcoat.  I would love to find some kind of paint that is ok for use under the waterline for a few days.  While working on the Imron yesterday I was tempted to go back with that above the waterline. It has held up really well for the past 15 years.
Still on the fence though.

Washed the boat down early this morning along with the console. I planned on trying to prime the bottom today.  They dried pretty quick and then it rained all of a sudden   So much for priming.
So I came back out a little while later and glued together a few pieces of epoxy lamination scraps I had together and then cut them into 2"Hx3"Wx 7/16"T "pads" that I mounted on the lower portion of the transom to mount my FF transducer so I'm not drilling into my new transom core.
I drilled a hole in the middle and lightly drilled into the transom skin and put a pretty short screw in to hold the 5min epoxy until it hardened. I scruffed up the area under each of the pads.


You can get the idea of the mounting here - and that is with the transducer about 1/4" proud of the bottom


I put one on each side in case I have to move it to the other side for some reason.  I also mounted them in 10" from where the chine starts in case I need 9" tabs in the future.


I'll put the screws a little later today, mix up some thickened epoxy and fill the holes.  Maybe tomorrow will be a priming day?

Nice touch with the pads

[RickK]

Thanks Craig.

I used a countersink bit and made the holes bigger and then dug out any resin left from the bit. I ground out enough around the pads and also cleaned them up with a 2" drill mounted round sandpaper (60 grit - Harbor Freight).


On this pic you can see the screw holes from where the transducer had been mounted.


I can never mix a tiny portion of epoxy - the measuring cups don't usually go into small enough increments. The pumps (and I have them) would have pumped too much also for this. I only needed about a quarter in size, maybe a half dollar size, to fill the holes and pack it in good.  The smallest I could mix was 3 oz. then added cabosil and figured I would try a fillet to help secure them and also make it look better.  I ended up with about half or more of what I mixed 




I'll take a dowel tomorrow and wrap some sandpaper around it and smooth the fillets down a bit so the pads look like they were planned instead of last minute, like they were.
Hopefully the weather will leave me alone tomorrow,

Awesome work, as usual! I am looking forward to seeing her in primer (probably not as much as you though...

As far as paint, have you looked into the EMC paints at all? I'm not just bring it up because I bought it, especially since I haven't put any on yet... Just going off of the TDS, it seems to be a pretty awesome product.

[larsli68]

Looking great Rick!
Great idea with the pads. 
I hope the weather cooperates better soon. We have stormy weather here. It is supposed to last all week. I don't know what is up with the weather anymore...

[RickK]

Thanks Carl and Lars.
I am ready to prime, have the air hose out and ready and the primer is stirred.  Storms are popping up all around me so I don't know....
It'll take maybe 10 mins max to spray it but it needs to cure for at least an hour, I assume without rain getting to it 

[Callyb]

You might already be done, but I want you to know I am pulling for ya!

[RickK]

Thanks Carl 
The pads came out well




The storms gave me a break and I was able to get the first coat of primer on  
I wasn't happy with the way the HVLP gun was working, more pulsing instead of a steady spray.  I played with everything and it seems that it wasn't going to work right.  I'm using a 1.8 tip per paint mfr instructions. I put the 2.5 back on and tried it and it seems to spray better - I didn't notice this when I sprayed the gelcoat with Duratec.  I'll have to do a little researching I guess before the next coat.














One thing for sure is I have a lot of pinholes to fill 

[Callyb]

Looks nice. I'm glad the weather cooperated with you. I'm sure you'll get the gun issue figured out before long. I'm working on my boat today too, hopefully I'll have some pics to post up later.
