Yes, we did use sand in the pipe. It must be very dry and we welded ends on the pipe leaving just a small 1/8th hole to let any steam out. Have seen these explode when damp sand is used with the ends welded closed. We used the same method to bend handlebars for a vetran Jap twin we are currently building. Thanks.

wow! is that an E6? we have a 20's bike with the E6 Engine, do you know of any places to get spares for when we finally get round to restoring?

thanks, peter.

@PeteCovell Hi Peter. This one i an E5. There is no one place to find parts, but some items are obtained through word of mouth around the clubs, or swap meets, and other items we have had to make. Happy restoring.

Did you compact the sand or was it a special grade or simple builders sand?

I've attempted and had various levels of fail when bending exhaust tube but will try this next time I need a new exhaust.

The reason it flattened a little is because the pipe expands length ways and in diameter when it is heated up and so goes loose. What you need to do is put a large screw and pad in the end plate to push the sand down tight again after it is heated.

Thanks for responding so quickly.

Did you use sand in the pipe to avoid kinking? Beautiful job.
