The Craft

The cheapest upgrade
in tennis

Same frame, different animal. Fresh string at the right tension gives you more bite on the topspin, easier depth when your arm is tired, and a sweet spot you can find without looking.

Most players wait for a snap. By then the string bed has been dead for months, and a dead bed is why winners stop coming off the same swing. String is not an accessory. It is the only part of the racquet that touches the ball.

Stringsmith is a one-man workshop in South Harrow. Every frame goes on a Gamma Momentum 6+, gets strung to the pound, and comes back with a straight answer: what went on, at what tension, and why.

The Bench

Gamma Momentum 6+

Precision without electronics. A drop weight is pure physics: gravity does not drift and does not need calibrating. It pulls the same pound on your racquet as it did on the last hundred.

Why a drop weight? Electronic machines are faster. A drop weight is accurate on every single pull, and this is a one-frame-at-a-time bench. Accuracy wins.

Questions

Asked often, answered straight

How long does a restring take?

Three days as standard. Drop off before 2pm on the express service and it is ready the next day for £30.

Do I need to cut my old strings out first?

No. Leave them in, cutting them out properly is part of the job. If a string has already snapped, that is fine too.

I do not know what string or tension I want.

That is the normal case. Use the Workbench for a data-backed recommendation, or leave both blank on the job sheet and I will pick based on how you play.

Can I bring my own string?

Yes, a full set (around 12 metres). Labour only is £20. If you bring a reel, I will measure what is needed.

How often should I restring?

The old rule holds: as many times per year as you play per week. Poly players should not go past 3 months even without a break, the string goes dead long before it snaps.

What if my grommets are worn?

I check every frame on the mount. Small problems get sorted on the bench; anything bigger and I will message you before stringing.

How do I pay?

Cash, bank transfer, or a Monzo payment link sent on WhatsApp once your booking is confirmed. Nothing is paid on this site.
