Barnfind Thread Injector---Bikepacking it out

[webhanger]

Thats crazy cool! I'd have never thought it possible to restore it, I think your gonna pull it off. I vote for woodland marpat with the flying tiger face for the paint job. The perfect blend of nostalgia and modern stealthiness.

The cheapest way to free it out would be to leave it in a tub of diesel it's will work the same as penetrating fluid at a fraction of the cost

Well, I went with the muratic acid and it worked. Soaked an assortment of smaller parts & plates for almost 24 hrs. here's how some of the pieces came out.


It worked great for removing rust & gunk, and didn't touch the small areas that still had chrome remaining.
The bobbin assembly (not shown here) is completely cleaned up but needs some polishing to make it usable - maybe . . . more pics to come.

Nice! Nothing like using chemistry to do our work for us!

Just wondering how this project is coming along.....any updates?

[Klaussinator]

Yeah, it's been sitting on hold for a few weeks while I was responsible for major upgrades at the studio (hey work comes first . . . ) We've now got a full-blown Pro-Tools system up and running, so I should have some down time in the evenings.

Next challenge is to see whether or not the bobbin assembly will polish-up enough to be usable... will post updates soon!

Well, I finally found some time to settle back into the tedious process of bringing this thing back to life - one piece at a time.

Kind of interesting, all metal parts seem like they will be servicable with some work, the only exceptions being the spring steel used in the thread tensioner and the bobbin winder. I don't mind buying these two springs if everything else can be made to work.

I've got a few more pieces to remove and put through the muratic acid dip. This plus some careful work with a wire wheel and lots of elbow grease are yielding parts that are still pitted, yet can be cleaned to a relatively smooth feel. After seeing how these parts look, I think I've made the decision to shoot for a 201 "Patina Finish" machine. These parts really have a cool look and feel to them, and I'm afraid that overall thi machine is just too far gone to restore to a cool glossy finish.

The plan is to strip and clean all parts as far as they'll go without trying to remove any good paint. The end result should be an interesting mix of original paint, bare pitted metal, and everything in between. Thinking I may need a clear-coat of som sort to prevent rust . . . although it'll be a while to get to that point.

Here are some fresh pics of some old parts in their resurrected beauty.









Will update as I go . . .

This is a great project, I wouldn't have the patience, but I really respect those that do.

Oh I've got patience --- I just can't find the time to make use of it!

the table/desk in the 1st post appears to be an old school home making unit

they were darn near bullet proof & proved it by enduring years of student use/abuse...

i know you are having a ball with this project

i find these heads, in good shape, at garage sales & flea mkts, regularly/weekly, for $20±

if you end up not able to get any of the parts back in service, these old units might be an alternative source for parts

LOVE YOUR PROJECT

more pics, please
