    I tried the PVC pipe approach. Even with 3" pipe it is too heavy. My racquet strung and leaded is 342 grams. The pseudo-sweet spotter I made with pvc was almost 3 times that weight. I need to find something thinner and lighter.

    Did you beat the hat you made against your head as a child? Just wondering.

    So.. please someone clarify this for me: how is this device better than a simple good old wood tennis racquet? One with a 65 sq in head. You can pick the weight, the balance, and they come with leather grips most of the time.. all of that for the princely price of about $5.

    Save your money and save a woody!

    I doubt that it is better. It is not hard to find wood in the 11.5oz weight range with smaller grips. That's light enough to lead the racquet into a more modern polarized weight distribution without being heavier than many modern racquets.

    The SweetSpotter (lame name BTW) could in fact be better than a wood but I doubt it is $195 better.

    Save your money and save a woody!

    Look for thinner schedule 20 PVC. My HomeDepot does not carry it, but Lowes does.

    20 - Thinner
    40 - Thick
    80 - Thicker

    Still need to build a tennis grip on those. Not impossible or cheap, but will add about 30 Grams and $70 bucks

    $70, where did you get that number? I think it could be done much cheaper.

    Not if you already have old tennis racquets you can cannibalize.

    one approach would be to print the grips to fit the bat and match your desired grip shape/size on a Rapid Prototyping machine.

    I've done it.

    Hence, $70 and 30 grams.

    yes, because at their level, it is expected of them. To look at something and say "thats amazing" is to declare that it is so advanced, that i somehow have difficulty comprehending it, only because it is on a somewhat unknown frontier.

    So even if it is far above our own capabilities, most of it is viewed reasonably possible, therefore mortal.

    But when you get into the top 20 say, the Federers, the Michael Jordans, Tiger Woods(pre fallout), or anyone at the top of thier game/talented, sports, music, or whatever have you. These are those that are truly amazing on the cutting edge of presenting abilities above the normal mortal comprehension. They have reached that "ethereal like zone of perfection" and transcend their own abilities often.

    However, at all levels, we feel that our own tennis is amazing, with just cause, because it transends what we expect of ourselves. Isnt this what keeps us
    playing the sport?

    But also , this leaves the door open to common err, in that we compare our abilities to someone on a higer level than us, and reason that, if we feel our play is amazing to us, then so much more his play is more amazing. We err, in that comparison, because to the higher level player, he may not feel amazing on that day. He may even be having a off-day, where he is not up to par or satisfied with his play.

    Or, he trains so much, that he feels routine,... the norm so to speak.

    youre welcome

    Yes, I have developed and have brought numerous products to market. It is also what I continue to do with more than one business I own, so I am very familiar with start up costs for products far more complicated than Yan's bat.

    With CAD and CAM, plus vastly reduced moulding expense, cost to develop a brand new product from scratch is far less than in the past. I have been doing this for more than 25 years in various product segments. It is what I continue to do for a living. Yan, being a tennis coach and neophyte to manufacturing, obviously lacks experience and contacts to get the job done right based on his numbers.

    If he is planning to sell through large scale distributors (like TW), this is typically what is called a 50-point product. So, distributor cost is half of the retail cost. "Manufacturers" (Yan in this case) need to bring the product in at roughly half of distributor cost. At $199.00 retail, distributor cost is $99.99. Yan needs to make the product at $50.00, inclusive of ocean shipping and duty. That is an amazingly high cost for such a simplistic product. It's an absolute **** and bake of the guy who knows nothing of what he is doing.

    Something else I noticed that bothers me:

    ". . .let us throw in your own online course on how to practice the Perfect Serve with the Sweet Spotter (a $100 value complimentary)" He's clamming the instruction manual as a $100 value, for free. Gee thanks.

    Oddly enough I could not find a patent for it online. If it is patent pending that is usually plastered on a product website.

    I'm going to make one from a racquet handle I cut off an old racquet and a T-ball baseball bat. The bat as is is 25" and 13 ounces but I'm going to cut the knob off and put the handle over the small end of the bat with some type of adhesive.

    The only problem is that the barrel of a T-ball bat is only 2 1/4 inches which is a bit small. I'm looking around for a short Senior League bat which has a 2 5/8" barrel. I want to keep the total weight of whatever I create close to the 13 ounces my racquet weighs.

    The problem with using a bat like they did is the bat's weight is a lot more than a tennis racquet and possibly that it is a bit longer than a racquet. T-ball bats are the only type I found which weigh in around the weight of a tennis racquet and are about the right length. The one I bought was 14 ounces and 25" long which since the top 2" of a 27" tennis racquet aren't used for hitting is just about the right length.

    Senior league bats at the shortest lengths get down to around 15 ounces but the cheapest ones I've found are around $60 and I don't want to spend that much on an experiment even if they do offer a bigger 2 5/8" barrel as opposed to the 2 1/4" barrel on a T-ball bat. OTOH the T-ball bat I bought to test this out was only $15.

    And this product helps how?

    So.. we start with a baseball bat in order to learn how to serve... but a baseball bat is not like a racket so we end up modifying it so that it feels like a racket.. We are trying to make a baseball bat that feels like a racquet so we can learn how to hit with a racquet? ... Makes total sense... now $199 seems like a bargain.:???:

    The second part of your statement is roughly correct.

    The first part is only half correct. Indeed, if you work in the moulding industry you probably have the connections to have a mould built for $5000. That's because someone will donate their time. However, given the size of the contraption, and based on the quotes I got, a mould would indeed cost $30k-$40K, if made in the USA. Now, if you or anyone else knows someone who would make it for $5-10K, please contact me, I have several projects and I want to work with them.

    NO, but you can borrow it anytime to fulfill your childhood fantasies.

    Here's a thought: why dont you go steal a bat from some little leager, to avoid some senior going ballistic on you, and save the big $$ altogether? LOL

    I love how you skipped the hardest part, which is HOW to get into large retailers like TW, which is EXTREMELY difficult.(even more difficult if you want to get into a physical store due to shelf space limitation)

    Senior league is what comes after Little league. It is for 13 to 16 year olds which sounds like your peer group.

    what's the smallest headsize racquet you can buy that is currently sold?

    Wooden, or modern. Surely that's a better way.

    I like the baseball idea better though because mishitting a tennis ball with a baseball bat isn't going to kill your wrist/elbow/shoulder. Instead the ball will just shoot out sideways.

    Went out today and hit about 150 serves with an ultra light tee ball bat. I probably would have seen better results if there weren't 20-30mph winds out today but here was my experience

    first 20-25 ball shot out sideways to my right either hitting the side fence on the fly or going over it. then i started to hit the center of the bat a got some forward direction on the ball. Managed to get 4 good serves in box on balls 35-50. Switched sides and hit into the ad court, completed wiffed a few before adjusted to the wind coming from the other direction. After about 20 or so balls on that sides I managed to get a good 7-8 serves in the box. Went back to the other side again and managed to get anther 8 or so in. All in all i probably made about 20 good serves out of 150 balls.

    But I could definitely see the benefit to training like this. When I did managed to connect the serve felt really solid and they were really jumping and hitting the back fence with some pace.

    I feel I could definitely up my 1st serve percentage as well as mph though I would really like to find a way to alter the grip to make it more tennis like.

    Tried to drop feed a few groundstrokes as well but the grip was even more awkward for groundies than serves.

    Thanks for the report.
    So far on the one I am making I have cut the knob off the t-ball bat I bought and cut the handle off an old racquet and hollowed it out then put the bat inside the handle and added gorilla glue. Tomorrow if everything is dry and secure I'll rewrap the leather grip and put the same overgrip I use on my regular racquet on it and test it out. It weighed in at just over 13 ounces total and just under 26 inches long which is almost exactly what I was shooting for.

    My leaded, strung, Head Microgel Radical OS with an overgrip weighs just over 13 ounces. It works for me but I realize that that much weight isn't for everyone.

    The bat is aluminum and after I cut the knob off the end and removed the grip it was 12.5 ounces. The racquet handle I am using was 1 ounce after I hollowed it out and cut it short since my strokes are all one handed. The total together after using adhesive to bind them was just under 14 ounces. I will post a picture later.

    Can't wait for the pic -

    curious, is the weight distribution roughly the same? I'm not too familiar with bats, aren't they a bit head heavy?

    My racquet is just a wee bit head light (1 point IIRC) and the bat is definitely weighted more toward the business end than the racquet. I'll weigh them both tonight and post how head heavy or light each is.

    This is just an experiment (and one done about as cheaply as possible) so I don't expect the bat to match the characteristics of my racquet exactly. I think the idea of using the bat is to help you focus on hitting right on the sweet spot because off center hits with the bat are going to give a lot more negative feedback than with a racquet.

    I can't see how it is. Unless you're committed to hitting dead flat all the time, practicing with a bat just isn't where it's at. A small head will still let you hit with spin but the smaller surface area and torsional instability of a narrow-headed racquet will force you to make contact closer to the center of the strings. Stick some low tension poly in a wood racquet and you've got a better tool to encourage good ball-striking skills than a bat, IMHO. A better sweetspotter would have a flat hitting surface about 6" wide. The surface should be textured to allow you to apply spin. But then you've got wind resistance from that flat surface, so you'd want to put lots of holes it, and at that point you may as well just use a small-headed racquet.

    Pictures of my homemade Sweet Spotter:
    The handle from an old prince racquet I cut off and epoxied to the T-Ball bat. I hit everything one-handed so I cut about 2 inches off the handle to get the weight down.
    [​IMG]

    The handle after rewrapping the (very) old leather grip.
    [​IMG]

    I cut the knob and another 1.5 inches off the bat so the whole thing with handle would be under 26" and about 15 ounces.
    [​IMG]

    The whole thing weighed in at just over 15 ounces with an overgrip which I can live with. I think I got the handle attached pretty straight on the bat as it is able to stand upright with the handle end down.
