I’d like to meet all the SCCA rules for Formula 1000, but sourcing the required tubing in Thailand is difficult. The prototype will have to be an adaptation of the US rules to fit tubing sizes and types available locally. Where SCCA rules require seamless or drawn-over-mandrel tubing for the roll cage, I’ll be using ERW (electrical resistance welded) tubes. I’ll also be modifying the required diameters and thicknesses a bit. That means this first prototype won’t be able to be homologated under SCCA rules for racing in the US, but realistically that wasn’t going to happen anyway. I visited a shop called “Boon Racing Pattaya” and talked to the owner about tubing. He said everyone in Thailand uses ERW for roll cages and recommended I visit Chinatown in Bangkok to buy any unusual sizes or types.
