    What comes in a Home Grown Kit?

    Each kit comes with all the material you need to build your own board including: board frame, cedar planks and rail strips, wood scraps (sized for tail blocks, and minor structural blocking), fin box, leash plug, waterproof glue, fiberglass, and more. Epoxy, squeegee, mixing buckets and rubber gloves are sent directly from MAS Epoxy to save shipping costs. A detailed 170-page instruction manual tells you how to assemble it all. Our kits are put together by hand in Maine from locally grown, sustainably harvested northern white cedar and a small amount of red cedar for color variation. You will find planks numbered in a suggested pattern and marked “top”, “bottom”, “nose” and “tail”. The rail strips are already milled with a nose and cove that allows them to work around the rails (see the manual).

    How much skill does it take to build a Home Grown Kit? Do you have to be a woodworker?

    You don’t have to be a woodworker at all to successfully assemble a kit as long as you can use care and take your time. It is true, however, that woodworkers will find some parts of this process second nature.

    The most critical parts of assembling a Grain Home Grown Surfboard Kit are getting good mating between glued parts, eyeballing fair lines as you shape the assembled parts, and getting a good epoxy lamination. Many of the parts are pre-machined so that most of the cutting and fitting needed is already done, and kit builders have only to trim off excess after assembly is complete. The epoxy lamination is not difficult and the MAS Epoxy we use in the kits is very forgiving and sets up slowly to give you plenty of time.

    If you are not a woodworker, take time to make sure your tools are sharp, go slowly and read the whole manual before you begin so that you can better anticipate the impact of what you may be doing on the following steps. And follow this old wood-working adage: “measure twice, cut once”. It is far easier to take wood off - especially with a soft wood like cedar - than it is to put it back.

    So go slowly and avoid the use of too many power tools. The image you have of board shapers striding up and down the shaping bay with power planers and 8” disk sanders is better expelled from your mind as it is tremendously easy to take off more wood than you would like. Stick with hand planes, spokeshaves (if you have one) and hand- sanding blocks if you have any doubts. Stop very often and admire your work - very closely from the nose and side - with one eye closed so that you can detect problems as they are developing rather than when they are too advanced to fix easily.

    Finally, keep in mind that when you are done, there will be a few things you will have wished you had done differently. All hand-made things have a few imperfections and that is part of their appeal. One day, you will be sitting on that board waiting for the next set, and you’ll look down at the clear seawater washing over a beautiful grain pattern and you will be amped that it looks great and surfs and you made it yourself! What could be better?

    What kind of tools do I need to build a board?

    This depends to some degree on your personal ingenuity... but the Grain builders recommend the following:

    • At least 4 bar clamps (min. 24”span - more is far better)
    • 20- 2” and/or 3” Spring Clamps
    • Caulking Gun
    • Small Plane (sharp)
    • Chisels (sharp)
    • Clothes iron
    • Masking tape
    • Duct Tape
    • 80, 120, 220, 400, and 600 grit sandpaper
    • Electric Sander or sanding block, muscle and persistence
    • Drill with assorted bits
    • 2x6 by whatever length of board you’re building
    • Strapping (as is used in construction)
    • Misc scraps of plywood and/or 2x4’s (24” lengths) used for creating a rocker table
    • Cheap bristle brushes or foam brushes for epoxy work
    • Foam Brushes for varnish

    Do not neglect the critical basics: Dust masks, safety glasses and surgical or rubber gloves. Pay heed to safe handling standards for epoxy such as those outlined here: http://www.masepoxies.com/safety.htm

    There are several things that you can do to reduce the number of new tools that you need to buy. Instead of spring clamps, old four-inch PVC pipe can be recycled into clamps (see manual). Instead of purchasing bar clamps, there are several ways to build your own or create a clamping table. Try these links for ideas: [1], [2], and [3].

    If you are planning to buy tools, do yourself and the planet a favor and purchase the highest quality tools you can afford from local sources. The farther away are the suppliers of the things we use every day, the more it harms the planet. And tools of good quality will last several lifetimes which means that your granddaughter or grandson may inherit not only the surfboard you build today but also the tools you used to build it with a fewer made-to-throwaway items entering the waste stream to boot. It will mean a lot to future generations in several ways.

    How long does it take to build a board?

    The actual hours that you spend building your board will depend on your skill level, the complexity of the board design you are building, and choices you may make about customizing the board’s finish, but you can count on anywhere between fifty and eighty hours.

    This time will be applied to the project in smallish chunks as you must wait for glue to dry before moving on to subsequent steps. Many kit builders will reserve an hour in the morning and/or evening before and after school or work as well as time over weekends.

    The swallow tails look complicated. Are they?

    Swallow tails are the split tail found on our fish models. They are more work to build than the squash tails featured in our other boards, but are not terribly complicated to do... just time-consuming.

    The two places that swallow tails can trip you up are:

    1. In fairing off the top of the tail block that is mostly inside the board. You will need to eyeball with a two-foot piece of ¼” strip along the tops of the three frames nearest the tail to see where the top of the tailblock should be faired to. The manual is explicit on this point, so read it carefully.

    2. In fitting the fiberglass cloth up into the narrow part of the swallow tail. A small patch can be added before the main lamination to ensure full coverage. You can check back while the epoxy is setting up to be sure that the cloth around this tight area is not bubbling up.

    I am pretty good with tools but frankly, I am scared to try the glassing...should I be?

    Not really. Good glassing is a question of careful surface preparation, basic hand-eye coordination, understanding when to apply pressure to the squeegee, and timing. It’s actually pretty easy if you follow a few basic principles (the manual spells them out for you).

    The main complication is that that you will be laminating over a compound-curve surface - in other words, it is a plane that changes in all three dimensions as you move the squeegee up and down the board.

    If you would like to, do a little practice... get a large section of the off- cut cedar panels from your board, and a section of the glass cloth that was trimmed in preparation for your first lamination. Prepare the wood scraps as you would the board you want to laminate, and apply some scraps of cloth. If you want an even better sense, bend the wood scrap over something curved before doing the practice lamination - that will give you a better idea of laminating a curved surface.

    Naturally, it becomes easier with practice, but more experience improves how quickly you can do it more than it does the quality of your work. Which is to say, work slowly and be thorough and the glassing will go well.

    In addition, there are a number of resources online that can help you get a better handle on some of the variables and some hints and tips. Try these from Stephen Pirsch: [1], [2], [3].

    How much can I modify the design and/or look of a Grain Homegrown Kit?

    There are actually a lot of options you can choose with one main restriction: The actual shape of the board is defined by the precision- cut internal frame. Even with that, there is some latitude in shaping the rails - particularly near the bottom as long you don’t remove too much material.

    It is still possible to manipulate the shape a little if you have some ideas that you want to try out. For instance, you can extend the length of the board a bit by adding a longer tailblock. Or you could decide that you want a pintail instead of the squashtail that is designed into most of our boards. You can even put some very limited concaves in the bottom if you want and are very careful (Some boards such as the 6’5” single fin have bottom contours built in to the shape of the frame. For these places, you simply need to force the planks into the shape. No further shaping is necessary). It is also pretty easy to make the nose of the board a bit finer or blunter if you want. There are some other possibilities which we can talk about if you have specific ideas.

    The way you "plank" the board also allows some latitude. You can put inlays of other woods, or paint colors or accent stripes, etc. Compare our boards to the ones this customer built using only our frames and some leftover stock he had from a kayak project. You will see that he chose to chop off the rails that were machined into our frames so that he could build-up his own. This will result in a heavier board, but he will have no limits on the way the rails are shaped. This would require that you have a tablesaw available to you.

    It is also possible to add custom paint tints, art or even fabrics during the lamination and epoxy coats. The boards to which we have added some color highlights have been very popular. Print out logos or other art that you want onto acetate using your inkjet or laser printer and laminate them on as well.

    For those with a steady hand, inlays of other woods, plastics or other materials can also be done - but be careful: the skin of your board is a maximum of ¼” thick!

    How complete is the Home Grown Kit manual?

    The manual is a step-by-step description of how to assemble a Home Grown kit. It is loaded with large pictures that show lots of detail, and it is under regular revision as we have time and think of more information that would be useful to kit builders. We are looking for comments and feedback as to how easy it is to follow the manual’s steps so let us know what is lacking!

    Can I build this sucker in my apartment/living room/dorm room?

    That depends on whether you live alone. Your board may take as much as two full work weeks to build IF you were working on it non- stop. Chances are you are more likely to do a little at a time every day - plus weekends - for a couple of months. Be sure that your mom/wife/husband/roommate is cool with having your new stick growing in the middle of the room for that long. Good luck with that.

    You might also disclose to your loved one that you will be generating an incredible amount of wood shavings, saw dust and sanding dust which, though aromatic, is not good to breathe. Let’s not even talk about the epoxy resin which will drip off the sides of the cloth onto whatever floor covering you forgot to spread a drop-cloth over.

    You will need enough room for a rocker table longer than the length of your board, with at least two feet of space around all sides, plus some surface to assemble parts on (like a workbench or table) and places to put tools and supplies. If you are only building one kit, you may choose to break down your rocker table once the top is on the board and build some shaping stands from the parts which will help you recover some floor space as well as get the board up at a good working height for shaping, glassing and finishing.

    Good lighting is essential - when you begin shaping and sanding, you will want it at the same level as the board itself so that you can see imperfections.

    I would like to go into business building Grain Kits for others. Any problem with that?

    A little...because our original intention was to develop a kit for people that were like us - surfers with just a basement, some tools and a desire to surf boards we built ourselves. The excitement that comes from making it yourself is what we were after!

    But some people don’t feel confident building their own, and it sounds like we are all interested in seeing more wooden surfboards out there, so we would like to work with you to help that happen. Grain is in the process of creating a licensing program that will allow the use of our method and kits for other commercial building enterprises. Let us know your plans and we will try to help make it happen!
