Hi,

Many thanks

Richard,

Do you mean a 9.7 mm reamer or a 3/8" one?

I have the latter you can borrow.

Thanks for the suggestion - one of my first searches actually.
Needed to have a bespoke reamer made for me - plenty available off the shelf from China etc but didn't want the obvious risks to say nothing about keeping my purchases from UK sources where possible.

I assume you'd thought of 3/8" and after using first for that size, then raising the lands with a file drawn along the lands to get the extra 3 thou. radius.

Might be worth turnng up a spot on plug gauge carefully polished on a lathe to check the final bore, or of course if suitable, the actual item that goes in your 9.7 mm bore ???

Mike,

I didn't want to bore you - ouch!! - with the details but I'm working in a very confined space changing a fastener from a high tolerance 3/8" AN176 to 10mm ground shouldered bolt; not a wing pin exactly but something similar.

Hand reaming when fitting the 3/8" fasteners worked well using a ratcheted ring spanner to turn the reamer smoothly in 1/4 turn increments through in-line 4130 bushes. The challenge has been to obtain reamers that allow me to ream further to 10mm. It is work in progress but today I got a lucky break after a bad start.

The initial set-back was discovering that the bespoke 9.7mm reamer I was depending upon turned out to be a parallel machine reamer, rather than a hand reamer which has a slightly tapered lead. And anyway there was insufficient space for a chuck to grasp the shank.

There was an unexpected break-through when a 'new 40 yr old stock' reamer with an impenetrable MOD code instead of a simple diameter that I had bought for a modest price from ebay as a '9.9mm' hand reamer turned out to be 9.75mm (unless my micrometer has thrown a wobbly) with a 9.3mm initial lead. How lucky can one be !!

I'm expecting to be able to use this reamer followed by a standard 10mm hand reamer. We shall see!!

Thanks to respondents for taking helpful interest
Richard
