For the Columbia AA, does the nut which holds the mandrel to the upper works use a left-hand or a right hand thread?

Well, while I am on the subject--what about the same mandrel nut on the Columbia BKT?

Many thanks,

Steve

The nut on my BGT is a left hand thread. I suspect they all are. Jerry B.

The nuts used are left-handed thread. That way the mandrel will not get loose and fall off from operation. Congrats on your Columbia AA. They are scarce and nice machines.

Thanks! Yes I am excited about it and want to be very careful as I clean it up.

The Columbia AA is such an attractive little machine. Please show us a photo when finished. Jerry Blais

Jerry,

I still need to finish the motor so here is the machine without the motor for the moment. It came to me with a refinished cabinet and a decal that is not quite right, but I will leave it for the moment. I was very pleased with how the aluminum and nickel plate shined up.

That is so much cuteness in a tiny package. Thanks, Jerry Blais

I love the Columbia, I need to clean my BV up. This looks great.

Thanks! I am really enjoying the AA. It is nice to have a machine that doesn't strip a gut to pick it up.
