What Sac Size Do I Need?

[mariom]

I have a couple of pens which need new sacs and I'd like to have a go at doing it myself. This is at least in part driven by the cost of such repairs in Australia - the only local site which quotes prices is asking $45 for a re-sac - and partly because I'm a tinkerer. Both sections are out of the barrels and the barrels are clear of residue.

 

There are plenty of sites in the US or the UK offering the necessary supplies, but the postage costs involved mean I'd like to get things right before ordering. I'm leaning toward the starter kit from fountainpensacs.com , but I'd like to top up the order with the sacs I'm likely to use so that I still have a complete kit to choose from in future.

 

The pens are an Osmiroid 65 and an Onoto 1332. The nipple diameter on both is near enough to 6.85mm, which I calculate to be just over 17/64". The internal barrel diameter of both pens is around 8.3mm at the section. Does this mean I need a size 17 sac, or should I go a size smaller?

 

Also, if anyone knows of a good supplier of repair parts in Australia, I'd be happy to hear of it.

 

Thanks

You should go down a size to a #16. You would do well though to order a few in a range of sizes rather than just one sac though. In general #16 and #18 are in the middle of the curve, with 14 and 20 at the outer ends. I rarely use 12 and anything larger than a 20.

I suggest AusPens.com.

For what it's worth, I charge all of $3 for First Class International (airmail) shipping.

Not the fastest, and no tracking, but very little actually disappears en route.

Thanks David. I'm aware of your excellent service and have purchased from you in the past, and will likely do so again in future. The main reason I'm looking at the fountainpensacs.com offer is that it includes a variety of sacs together with shellac and talc in the one package.
