How not to repair a cracked mast. Longitudinal cracks had simply been filled and faired with light weight powder and epoxy. Then "wrapped" with woven carbon cloth to "fix" the cracks.

Not really a long term fix as any weakness such as cracks, voids, etc. left in the matrix, will ultimately fail through the carbon "working" under load, as seen here.

Carbon Fibre Spar Repairs

A proper fix. All suspect rubbish removed, new internal full diameter sleeve constructed to distribute heel bearing loads, half internal sleeve constructed to slide inside the mast past the deck bearing area and a half external sleeve constructed to cover the repair from heel to deck bearing.

All surfaces glued and fixed in place with double wrap of woven carbon cloth.

Carbon Fibre Spar Repairs

Not just carbon fibre masts but also any sporting equipment. Such as this racing bicycle frame. Steering boss was cracked and the aluminium bearing hub compressed out of shape.

Carbon Fibre Bicycle Repairs

Top bearing hub straightened (we could have just as easily machined a new bearing hub) and the cracked carbon fibre replaced with a custom patch. Easy and low cost repair on a carbon frame that cost more then most dinghy carbon spars.

Carbon Fibre Bicycle Repairs

Finn mast refurbishment - Perfectly good spar with worn out components including the deck ring, heel cap, gooseneck tangs, mast head pulley, halyard, halyard exit box plus kicker ropes.

Carbon Fibre Spar Repairs

Machined new customised deck ring and heel plug. Note cutout in heel plug to take halyard exit box.

Carbon Fibre Spar Repairs

Repaired gooseneck tangs and machined customised new boom bolt to fit. Halyard exit block is angles to prevent halyard chaffing on top holddown screw. Screws are tapped into heel plug. Uni carbon layed up at 90 degrees prevents splitting of the carbon matrix. All fittings replaced and new halyard fitted (3mm non stretch dyneema cored).

Carbon Fibre Spar Repairs

Typical repair on carbon fibre spars. Localised loading on the carbon matrix has resulted in cracks, delamination and potential failing of the carbon appendium. Layed up new lining, and strenghtened exterior surfaces with custom designed carbon layup.

All carbon fibre spar repairs, alterations or additions will be on a fixed-price contract.

Fixed-price contracts means you will not be suprised by an excessively high maintenance bill often found where an open-ended time-taken based cost structure is utilised.

Your carbon fibre spar repair will be done to budget.

With our ability to create custom components we can manufacture all unique or irreplaceable carbon fibre spar parts as and when required.
