Hi AllI have been lurking in this forum for a while and enjoyed your postings and pictures. So I hope that the gentlemen (and woman) here can help me.
A friend gave me a Beocord 1200. The machine was working fine, until he needed to cannibalise it to repair a newer model. The pinch roller rubber is completely missing. The centre bush of the roller is still there. He did not take dimensions of the roller before he removed it.
I would like to know is the dimensions of the roller for the beocord.
The other question would be how important it is to get the dimensions excactly right. Would a slightly larger or smaller diameter roller still work correctly?
Lastly, what type of rubber can be used to repair the roller? We have an excelent rubber molding workshop that I have used for automotive bushes. They are able to mold a new rubber section onto the bush, and computer cut it to being round. Would that work properly?
I look forward to your reponses.

Hi AllThanks for the responses. I will post again once I have some results to report.
Check with Terry Witt who rebuilds a lot of rubber rollers; idlers; et al. His Website is:www.srdpc.com/witt
Absolute diameter shouldn't be too critical as the arm the roller is mounted on is spring loaded to keep pressure on the capstan shaft. Could carefully check the amount of available "play" in the roller arm, and take half of that amount as the outside radius of the desired new pinch roller.
HiI've recently changed the rubber of the pinch rollers of my Revox B.710. I did it by taking out the rubber of newer pinch rollers. Cleaning all the residue of the old rubber and inserting the central metallic part of the pinch roller into the hole of the circular new rubber.
As for the diameter. I didn't matter. I just polished one of the rollers as it touched the erasing head (which is mounted next to it). The deck seems to work well. In any case I could modify the roller to capstan presure to accomodate different diameter pinch rollers.
