Mabie Todd Swan Sac Size

[Ego Id Veto]

Hey guys,

I bought a wonderful nearly perfect condition Swan Self-Filling BCHR at the Melbourne Pen Show this weekend, however when I leak tested it, sure enough the shellac holding the sac in place was shot, and so I will need to buy some shellac to glue it back on.

However I don't really trust this sac anyway, as it's old. So I'd rather replace it with a fresh one.

My question is though: what size is it?

I've looked at richardspens.com's sac guide but he doesn't mention Mabie Todd pens.

Anyone have any idea which size this sac is?

I've put a 5 dollar US note for scale, as I'm assuming most of you guys don't know the size of Aussie coins, so using them for scale would be useless.

Hi

 

IIRC the last one I changed was a #17, this is where I find an imperial drill gauge indispensable, as they have a lot of holes in the 64th range and sacs are sized in 64th's so a #17 is 17/64, all you do is find the hole that the nipple just fits through and use that size

 

Something like this one.

Thanks Paul (scratching my head) Why didn't I think to use my drill gauge for pen sac sizing?

 

I store a pretty sizable stock of spare sacs in a clear plastic Plano compartmented box. Not long ago I knocked it over...spent a looong time separating sacs into their respective compartments... hence, I will tape a dill gauge to the lid.

 

This is one of the many reasons why I love FPN!

Thanks, Paul. [bangs head next to keyboard] I have a perfectly good drill gauge in my tool kit. [bangs head again] Sigh. At least my wife pointed out that I have a Starrett sliding caliper in 64ths; I'd been using my B&S dial caliper and converting.

 

Pardon me whilst I go back to slamming my head on the desk top...

There is a special procedure for MT Leverless pens (see Pen Repair book).

Basically, the filling system demands the maximum size sac that will fit in the barrel and should be pushed in with a stick inserted through the section. The nib and feed is fitted last. If you do not do it this way, the pen will never be fillable to its designed ink capacity.
