Hi,

Well so far I have not found any specific info on the size of the capstan wheel. From the deteriorated capstan of my TI-59 I can guess that the outer diameter is about 8mm, but I can't be sure because the capstan was already gooey. I have tried silicon tubing with an OD of 8mm but there is slippage. My guess is that's a bit too wide, so probably needs a bit of sanding.

I can do it by trial and error, but if anybody has the figure it would sure help to speed things up.

Thanks
