Hi BJ and thanks for your comment - it's always pleasant to hear from a fellow enthusiast and it's very rewarding to hear one of my Instructables (which, if truth be told, can often take just as long if not longer to put together than the task it's describing!) is appreciated. Since I wrote the 770 piece we acquired ourselves a lovely* but time-consuming border terrier - I consequently have a number of unfinished or even unstarted Instructables awaiting a possible future time when the BT is able to entertain himself without getting himself into trouble ;-) Cheers, Mike* except when he's not.

Hi DimitriThanks for your kind comment - thankfully I didn't have to replace the pinch rollers but just cleaned them. I haven't researched where you could buy replacements so can't help with any first hand knowledge - sorry!Mike

Hi Steve - thanks for your comment.In comparison with modern electronics those Aiwa decks are a real rat's nest but it's good to hear there are easier ones to work on.There are a few websites where I found the belt dimensions but I've struggled to find them again - however, my Instructable has a link to where I got my belts from (a quick check today shows the belts are still available). The deck has been working fine since I fitted them. Incidentally, I found a website with the service manual and specs for the AD-F810 if you're interested - https://www.hifiengine.com/manual_library/aiwa/ad-... and here's a discussion about AD-F770 idler wheels - http://www.tapeheads.net/showthread.php?s=54c64ac7...Best of luck!Mike

You're welcome and thanks for the feedback. I hadn't considered the non-scratch 'feature' but I can see its merits!I guess if you were keen, you could make one with a small magnet in the base to keep the bit more securely in place but in this particular application of mine magnets are not a good thing...Cheers, Mike

I've started research into how to drive a 4" Bourdon gauge, application TBD - this looks a much more promising approach than ones I'd been considering (eg) direct drive of the spindle via a servo. Space will be the issue but your design definitely gives me food for thought. Thanks!

Oh I wish I had a 3D printer! Thanks for the link.

Thanks - I do feel a lot better about being underneath the thing since I added the restraint, although I always have to remember to duck!
