    WOW!!! Really looks great! I do not know much about these, but I have a friend who has made many of these boards and the pics you posted are exactly what I see going on in his shaping room! Plus his boards rides like nothing else!!! Great job bro!

    Thanks WOH.

    I meant to ask about adding vent holes. I've got one on a firewire and get the basic idea and since it will be significantly lower temps when I'm glassing vs. this summer I think it makes sense to have one. Anyone have a quick and dirty installation or ideas on where to get them or how to make them?

    You have to have a vent on a wooden board or it will implode or explode depending on water and air temps. Do not use a gortex vent. Those will eventually fail and you will get water in your board. Use a brass threaded insert and a brass screw with neoprene washer.
    TO install it you will just drill a hole slightly smaller than the insert size and either screw or hammer in the insert depending on the style you are using. You will have to seal around the edges of the insert with epoxy. I typically put epoxy all around the hole before installing the insert so it seats into a nice glob of epoxy. Just make sure you do not let any epoxy into the threads or you will not be able to screw into it.

    Good choice on the Sapele Mahogany--you're going to love how iridescent it is in different lights and angles. Did you buy it already in 1/8 inch veneer or did you mill it yourself?

    Yup, really enjoying working with the sapelle... I finished a small piece with some 1500 grit sand paper and you could really see how the light plays with the wood.

    The wood was pretty cleaned up when I bought it but I ripped it into 1/4" strips then ran it through a thickness planer. I'm going to leave a little more thickness on the top deck.

    Hopefully this weekend I'll be able to put a good chunk of work into this. I'll post more pics along the way.

    ya- need the vent- my friend used a plastic vent- that was about the size of a leash plug on the nose- it was a basic plastic threaded piece with an o-ring to seal. I do recall him mentioning that its not a great idea to ride them in extreme temps- in the cold water of winter ect... I think you can find this type of vent at west marine or some kind of marine supply. greenlight surf supply has the goretex ones, but as noted above, i don't know how well they work...

    i remember the bases of these drain/vent plugs being glasses into the board... and i think he placed them on the nose and used the bigger hand tighten screw so that you could actually vent the board with in the water

    Update!!!

    I've been taking my sweet time on this but making progress little by little. The rocker table confused me for a long time becuase I was trying to make everything too perfect. Simple is better.

    Anyway, pics show my rocker table, rocker table with bottom deck on, deck and board clamped down and the board with the bottom deck all glued up.

    I'm gonna work on the rails and top deck this weekend. I'll keep you updated.

    As usual, gimme feedback both positive, negative or other ideas.

    So... I bet you guys never thought you'd see this thread again. Well between a baby that has recently turned one, buying a house and moving across town, I have finally come closer to finishing my "Medium" minisimmons.

    The board is built more or less but I have to figure out this glassing thing. More like I have to decide on what I want to use. I've been searching the forum and found someone who said they liked this guys stuff on youtube and he was using Solarez.

    What are the pros and cons of Solarez?

    I called Greenlight this afternoon to ask about the glassing kits and they said for a hollow wooden board I'd want to use epoxy. I'd basically made up my mind already to use it so we're good on that. Are there epoxy products out there that superior to Solarez in a lot of ways?

    I'm drawn to Solarez because it is UV activated and the waste is minimal. That being said, I can easily be swayed as this is my first real glassing experiment. All my other experimenting was with the fiberglass cloth and resin you can get from Lowes for big ugly repairs on my canoe.

    I'm looking for help from one and all but I've got a couple of you that I'm really hoping chime in.

    THanks!

    I've usued west system epoxy. It works good and looks nice. Kind of expensive, like 150 a gallon. I've built a kayak, My next project is a board, can't wait. yours looks nice, did you do the design yourself?

    Yeah, it was my first build and I learned a lot through the building process. I'm excited about glassing. I've heard the west system is good but rock hard when it comes to sanding. Any thoughts?

    If you've built a kayak you should be able to make a board pretty easily. Go light with your wood. I used 1/2" poplar in the frame and you can tell when you pick it up. I'm going for lightweight, cheaper materials next time.

    You can glass with minimal waste with epoxy resin. Even the "fast cure" resin research epoxy sets up so predictably and slowly that there is no reason to have to mix up a bunch of extra resin. A three quart RR epoxy kit is $53 and if you plan to glass lightly (its wood so isn't one layer of cloth adequate for both the deck and the bottom?) and truly not waste a bunch of resin then three quarts would be enough.

    Just guessing here for a board that size:

    deck lam 28 oz
    bottom lam 28 oz
    deck hotcoat 18 oz
    bottom hotcoat 18 oz

    a bit less than three quarts. If you use a bit of the Additive F (which i would) then that $5 for 4 oz.

    UHhhhh.... bump.

    Come on. I need some glassing guidance here too! I appreciate the resin research comment. Still interested in solarez though. Pros, cons or other ideas out there for glassing on wood?

    UV cure polyester resin will get you better clarity and will allow you to gloss and polish to a high shine. Epoxy won't do that for you. Guys have done epoxy over wood with great results... it might even be the norm... but I've seen some that had a haze, which can really stand out over wood. Poly will be crystal clear. As for gloss and polish, poly gloss resin is the way to go, and after all that effort, you want that baby to shine. Some guys have done poly gloss over epoxy, but with mixed results on durability coming from the inferior bond of poly-to-epoxy.

    I guess what I'm saying is... you can get great results with epoxy. I've seen good ones, and not so good ones. But uv poly is not a mistake if you've already made up your mind. It may even give an inexperienced glasser the best shot at a showroom finish.

    I agree with that...I've got just a bit of experience glassing (maybe 25 boards) but learning a LOT every time out...sometimes the hard way!

    Out of the last eight maybe four have been Resin Research Epoxy and four have been UV cure poly resin. There are all kinds of good reasons to use epoxy, but man when it comes to:

    ease of lamination
    quick cure
    sheet-glass-flat hot coats (dont forget the surfacing agent!)
    NO FISH EYES
    easy sand out to a nice finish
    far less concern about ambient temperature

    UV Poly is easy to love.

    No telling man. I made my first cut a year ago. But like I said, I e had a baby bought a house and moved during this time. I also worked in my shed, living room and my brothers garage before I moved. It was not efficient to say te least.


    That being said, if you have all your tools, space and know how you should be able to comfortably put one together in a month. That's what I'm planning on for the next build. You could do it in a couple of days to a week. There is a lot of time watching the głue dry.

    Howd you do your rails? What was the price range for the project?

    It all depends on what you want to build with and what tools you have. A skill saw or band saw help a lot. I wouldn't want to do this with a jigsaw. You'll need a table saw if you're gonna rip your own wood for the deck. . I had to buy a lot of clamps and glue. You can go cheap or as expensive as you want on wood. Sapelle and poplar cost me $120 I think. I was advised against gorilla glue but it helped in a lot of uses. Titebond III was good for making the deck.

    Glassing looks like its gonna run about 100-150.

    I built up the rails with 1/4" strips. One by one. This is where you watch all the glue dry.
