One Piece Cigar Step Mandrel

[RHossack]

Someone recently posted a message where he made a nifty tool to turn town the transmission coupler.

This mandrel was hastily made with my roughing gouge just to see if it would work.

It is made of 0.5 delrin and is used to align the tubes into the blank.

One end is the Sierra tube and the other the cigar tube.

Blank mounted and glued on the mandrel.

I found another use by accident. When I was trying to turn this wood between centers the blank was so soft in the middle that it was flexing when lightly touched with the chisel.

I stuck the blank back on the mandrel and mounted it between centers and and it became a rigid fixture holding the blank.

Excellent idea, I might just make one myself

Well I still need to make one of your transmission nib mandrels if it warms up in the garage enough this weekend.

This little thing came to be when I mis-drilled a blank and my wife couldn't work the nib to get the refill out.

I didn't take any time with this ... used the roughing gouge and calipers.

Next one I will definitely make it longer and nicer looking and use a #4 center drill on the ends.

That's neat, but one may want to try this method. When I started making the single bodied cigar a couple of years ago, I found the quick way to grind off the coupler was to press it into the lower barrel and then chuck it up in a drill chuck and use a file to grind off the ring. I then would use a spare tube as a "floater" for the lower end of the blank, with the upper barrel glued in and then just turn on the mandrel as usual. Knock out the "floater" and then assemble.

Do you sell these mandrells??

Forget I asked. Will attempt to make it myself.
