Don't worry. Practise makes perfect

My average time is 40-50 min (33min is the best).In comparision with DinkALot I'm very leisurely

.
BTW- pictures should be ok now.

In my case the time is more due to the machine itself but i don't have time to update it so i continue this way, maybe this summer, i'll take it to the next level

By the way here is mine

http://www.badmintoncentral.com/foru...ad.php?t=22353

lots of similarity: my first mounting system is like yours but my larger green metal plate were blocking too many hole so i changed to a 4 point system.

I'd like to have more picture of your tensioning system, i'd like to make mine like this cause on my machine always have to thigh a screw to hold the string. here my email adresse (benoit.aspirault@gmail.com)

Also i like the way you made your inner mounting point but i can't do that on mine cause i also use it for tennis and i need my mounting plate to fits both type of racquet.

You have right- both “machines” have lots of similiarity. I have seen your thread before- your pictures suggested me an idea about mounting system.
I don’t have time now to take a new photos- maybe on the next week. If I take a new tensioning system photos , I will put here.

About mounting system- I think that you can make a smaller metal plate for badminton racquets, it shouldn’t block many holes and machine will have 6 (or 8!) points mounting. For tennis racquets you will use larger green metal plate.

Seems we have a lot of engineers in this forum, and DIY becomes a more popular topic.

Wonder when a major TV network can put up a special seriers like "Home Improvement - build your own string machine".

I'm affraid that isnt't a huge possibility of that. It could be to cause a wave of protest of the biggest companies which produce stringing machines

Keep up the good work

My next mod, when i'll have acess to a garage is definately to make the tensionner faster to mount, i lost lots of time by tighting this bolt at every string i tension, for the rest, i think the problem is me.

By the way, so far i strung about 30 racquet in tension variing between 16-22 lbs and i never cracked a racquet or broken a string. But last week i strung my At-700 at 20 lbs and the string broke directly in the outsite of the head middles hole during the first game of the tournament i was playing. i didn't changed anything in my technique except i forgot to add 1 lbs on the cross, a thing i usually do. I don't think this would have make the difference, i'm still confused about what caused this incident.

may i know how were you able to calculate the exact tension in the handle?

**Dreamzz** · 12-14-2006, 11:26 PM

i think it's an amazing thing to create a stringing machine that seems to work so well from scratch. plus, imagine the pride you must take in it.

I have used the fishing scale- on the pictures it’s hard to see that (search photography with yellow string). I put weight on some position, then checked a reading on the fishing scale and marked sign on the rod. Then I changed weight position, checked, reading, marked. And again and again until the weight moved on the end of rod. Accuracy on my machine is 1LBS from 13 to 33LBS.

After my stringing job cracked “only” one racquet (yonex cab 23MS), but it wasn’t my fault- on the frame was damage structure (my customer knew that and I restringed on his own risk). The tension was quite low (20/22lbs), the frame broke on the top after 5min playing.

I wonder is the tension sclae is linear with this tension system. By linear i mean the tension increase constantly with the distance.

The distance between signs on the tension scale isn’t constant. For example: between 6kg and 7kg is the shortest (3,5cm), between 14kg and 15kg- the longest (6cm), so the distance increases gradually. The rod- ~60cm, weight- ~1,1kg.
(1cm =0,39inch, 1kg=2,2lbs).
