Re: 1967 IMP Aztec -- Thoughts and suggestions for Rebuild maybe repower

I know it has been a little while since posting here last and sorry for the delay here guys. Seems that whenever i get off of work it rains and prevents me from the real work.

in between the rain and transmission repair i was able to get some grinding done on the transom. I forgot to ask the oh so important question before i began of when do you know you have done enough grinding? It seems i have found that answer out as you can see in the below picture, just above the BIG hole there is now a new smaller hole :mad: Had to try to be the perfectionist. once the transom was out there was a lip around the inside that took a lot of work grinding down.

As if the hole was not enough, my tyvek suit failed, then my respirator failed and i got a lung full of fine fiberglass dust, and my goggles kept fogging up and when i tried to wipe it off i forgot to take the grinder off the transom and the end result was another hole. now i have reason to the sand the entire outside transom and use that as an excuse for the admiral to allow painting the hull.

So i found a good deal on Tyvek suits if anyone is interested. I got some from Uline.com for 7$ apiece, one right by my house here, but you have to buy them in a 5 pack. They have a hood that zips up to your chin, and booties. I got tired of fighting with fogging goggles and then they do not fit right with the respirator on so i got a full faced one for 52.00 and found that grainger is not carrying the particulate/organic vapoer combo cartridges anymore so they are clearing out what they have. a box of 4 is 10.00 instead of 53.00 for a pair. SCORE! 1 box already here waiting for the other. THe mask comes in today and today i grind the rest down.

now the pics.

I know not all that impressive or interesting, but WOW how dirty.........

Guys, as they have said before on here make sure you have a GOOD WORKING respirator and cartridges. I took me about a week to stop the coughing and get the resin taste out of my mouth.

was able to get some more gringing done yesterday finally. the new respirator is GREAT and so are the tyvek suits. I was able to get one of the stringers and the lip where the deck will sit ground down about 99% when my small angle grinder went out, then switched to the 7" and the gears stripped out. off to HF today to get another 4 1/2 grinder for 12.99 so i can get more done today.

I hope to have all the grinding done within the next 2 days so that the remaining week /weekend i can get the transom and stringer cut, sealed and hopefully installed. I will get pictures up later as it was to dark when i finished last night.

Re: 1967 IMP Aztec -- Thoughts and suggestions for Rebuild maybe repower

yesterday was able to get some more grinding done, stbd side stringer completely gone and area for tabbing has been completed, same side also ground down where the floor will tab to the hull as well as where the transom will. Port side, stringer completely gone and most of it ground down as well.

Today hope to get the area where the stringer will be tabbed as well as the floor to the hull. Still have alot to grind out of the old engine compartment as well. Hopefully will have all of the grinding done by thursday night as long as the rain stays away, and i do not damage another grinder.

i was going to post pictures but when i looked a them you could not see any difference. maybe once i have the grinding done where you can see the difference.

One question i have, under the stringers there is a gray material that i assume they used to bed in the stringers with. SOme of it is soft most is hard. do i need to grind out all of that as well so i am down to the glass mat and just make sure that the whole area is smooth once it is all out?

Re: 1967 IMP Aztec -- Thoughts and suggestions for Rebuild maybe repower

Ok, so i am still working on the grinding, alost done. Have to wait on all the rain that rolls through for a few hours every day and of course only after work or on the weekends. I did get the template fro the transom done and starting on the stringer template as well since i would not work with power tools in the rain,

I do have a question regarding foam. when i pulled the floor there was none present under the floor, not really a surprise as there were no bulkheads left eihter. The isssue is was there foam at one time, but more importantly is whether or not it is REQUIRED to have it in there now by USCG regs, then how much of it do i need?

You could always go this route: http://picasaweb.google.com/pacerdude/EntireDeckReplacement89Celebrity224se#5305852018165355202 (that's also a real nice resto project worth checking out)

I actually did read his thread and check out his pictures, once i saw them it reminded me. Sounds like the way to go then as there will be little area for the foam when completed.

For attaching the deck around the edges there is a lip around mos of the hull to rest the deck on, but for the areas without the lip there can i glass in some cleats made of 1x2 coated with resin to act as the support for the side and then secure it to?

Another thought was, instead of screwing the deck down to the new stringers and possibly causing rot again if it is not sealed well in the hole or over the head, could i just use the PL premium or peanut butter for that matter along the contact points of the lip, cleats, stringers and bulkheads?

If it were me, I'd grind OFF that lip and tab the deck to the hull. Remember my drawing from Post #23. Go back and look at it.

I do remember that post. I guess i should not call it a lip but more of a ledge that that is part of the hull. if you look closely in the below pic you can see where i am talking about. sorry for the confusion. the spot where the bottom of the hull meets the gunnwale goin up, there is a ledge there but it stops about 3/4 of the way up to the bow where it disappears, kind of like the lapstrake. i will try to get some pics of the part i am talking about later today when i go out to work on it as long is it does not rain on me again.

I have ground down the glass on the ledge going forward to the bow as well as up the gunnwale for the new tabbing.

Re: 1967 IMP Aztec -- Thoughts and suggestions for Rebuild maybe repower

Ok, I gotcha now. Is that where the Original deck rested? If so then that's where the new deck should go as well, then just tab it up the sides of the the hull filling the gap with Peanut butter.

Yes and no, that is where part of the deck sat but then the tray sat on top of it and was not tied into the sides. it was a different setup than normal. So i do plan on doing just what you said though.

But, instead of screwing down the deck to the stingers and bulkheads below, will PL prem or Peanut Butter work just as well if not better so i am not putting holes into the newly completd glass work? would this be just as strong?

Yep PL Premium will hold the deck in place Just fine.
To keep your grinder from Burning Up make sure and Blow out as much dust as you can from the vent holes as often as you can.

Seems like forever since i have been able to post anything new or even able to do anything. I think i lost some momentum with all the heat.

So i was able to finally talk myself into dressing like a baked potato again to try and finish up the grinding. I think i finally got it done, but have a couple of questions. they will be at the end of the pictures.


Engine bay done...WHEW!!!!

P5231220.jpg



Bow section done

P5231221.jpg



Stern done

P5231223.jpg



Transom template cut out

P5231238.jpg



Transom cut out and test fitted the first piece

P5231224.jpg



Just at 2" thick for all 3 pieces going in

P5231241.jpg




SO, the first few questions, more after next photo set
1. i want to put either gelcoat, paint, or something in for the bilge area to help seal and protect as well. in the photos you can see the keel area where i did not grind down, would i need to inorder to paint it with bilgecoat, gelcoat or some other paint?

2. i did grind up the sides of the gunwale where the deck will be tabbed in, i think i went up about 4-6 inches, is that good enough?

3. this maybe overkill but for the stringers, i was thinking of gluing a 3/4" and 1/2" or two 3/4" pieces together to make the stringers and not have to put a top piece on and it would give me some good support for the floor. Then where they enter the engine area that will use the steel plates through bolted for the engine mounts, i was going to add another 3/4 piece on each side of each stringer so there would be 4 pieces of plywood for the engine area. Is that to much you think?

4. when installing the stringers should i tab, and wrap them then do the bulkheads or tab and wrap the stingers and the bulkeads all at one time? i was thinking that if i did the bulkheads after the stringers hopefully if the bulkheads went i would not have to worry about the stringers.

Re: 1967 IMP Aztec -- Thoughts and suggestions for Rebuild maybe repower

The other thing i found while grinding was a LARGE air bubble that grew and grew the more i ground away at it trying to get it completely out. it is right up against where the stringer will run for the port side by the engine compartment. my plan is to lay down 1 patch of 1708 just a little larger then the size of the area, wait unitl it tacks up then add another layer of 1708 about 3 inches over the first section. Will this be enough or do i need to do a third layer?

the problem area

P5231219.jpg




Another question i have is for the knee braces that i am adding to the stringers up the transom, how far up should i go and roughly how wide should it be from the transom towards the bow?

What is the best economical product to use for coating the bilge area?

Had to fix my motorcylce, finished up a transmission on the truck, now tomorrow i am going to try and get the stringers cut and seal the transom and stringers. while those cure i have to replace the control arms and lower ball joints in the truck, replace the AC orings, vaccuum it down and let it sit to make sure there is no leak. That should give me the time needed to finish with the second coat for sealing then gluing them all together so i can get them ready to be installed. I am still wiaitng for my cabosil and chopped strands to come in so i can make the PB. once i get that in, then hopefull the transom will get installed, PB around the edges, stringers in place with the PL premium.

How long does the PL need to sit before i fillet the sides of the stringers with PB so i can tab them in? or can i just tab after the PL is set? I am using 1708 that is 12" wide with 6" on the stringer and hull, 2 coats for each side and then wrap the top with one for a cap. Can i do all the tabbing for the transom and stringers for both layers one right after the other of do i need to wait until the next day?

Re: 1967 IMP Aztec -- Thoughts and suggestions for Rebuild maybe repower

ok....i did not under stand anything in what you were saying aboout the stringers and bulkheads.....?....glassing and then wrapping them?

first off.....lets talk gellcoat for the bilge area and bow...

its $ 60 a gallon and will go very far in that application.....gellcoat is what the pros use and is the best tool for the job.

over new glass....you are fine unless you used wax in the resin...then you have to grind off the wax before you can gellcoat it....i allways use unwaxed resin for everything and add wax if i need to.
for older fiberglass...a light scuff or if there is wax on it....then a full 24 grit sanding is needed.....this can be done quickly with a big 7 inch orbital or da sander

now...the stringers and bulkheads.
use pl if you want....all you are trying to do here is keep the stringer off the hull....place a thin wood (or even foam) shim on the hull under the stringer. then bed however you want.....for speed of the cure i like peanut butter.
tab the stringers with csm....after the tab cures...the stringer will stand by it self.....and you can glass it. i suggest one full layer of csm and one full layer of 1708 covering the whole thing. to wrap the stringer.....you can use csm or even cloth finishing veil...
the reason to glass before you add the bulkheads is to put a barrier between each stick of wood....kind of like a rot blocker.

as far as the transom knees...in an inboard situation.....the knees are not even neccasary...but if you want them (i did in my boat) just 6 or 8 ins is fine....then coat that with fiberglass for a water barrier.

that should hold you for a bit.....remember.....if you start right now.....and you use poly for the bedding compound....you can have the stringers in a and fully glassed in 4 hours...this part goes really quick.

oh...one thing.......whats up with that big round hole in the transom......shouldnt that look more like a key hole?
