Rick,

Your the first to make a comment on my signature comment 60's, good stuff!

With your welding recommendation are you talking (4) slots at each end of shaft, or (4) slots total?

Clois,
I have used a collapsible shaft from dare I say it Mitusbishi Mirage, lengthened it with 3/16" seamless tube, the collapse part is same as Speedway motors show!
The beauty of the Mirage column is the indicator mechansism is period looking, and the column has a needle roller bearing lower end, and ball bearing top end.
