Wheelchair beach wheels DIY assembly and details

The wheelchair brand is Invacare action 3, the kayak trolley brings the 2 wheels the 2 spacers and 4 lock pins. Link ( https://www.ebay.co.uk/itm/2646956848... ). Velcro straps eBay link ( https://www.ebay.co.uk/itm/2827004875... ). I also bought locally a stainless steel rod for the axle, the aluminium from the trolley did not work well. It will not be suitable for all chairs, depends on castor wheels size and chair design. If you like me will take the chair for saltwater use remember to wash with tap water after every use.
