Pinning hammer polishing and use for 0.3μm lapping film

[rbscebu]

A whole ago I was looking for a decent low mass ball pein hammer for SR pinning. I eventually found a 110g cross pein pinning hammer which I bought. Once received, I ground the cross pein head down into a small ball shape, also reducing the mass to about 95g. I then polished both head surfaces.

​

This morning I decided to repolish the head surfaces as they were starting to show some very faint marks. Started with 1k W&D, then 2k.

This got me thinking. I had a few strips of 0.3μm lapping film that I never seem to use. I decided to give the heads a polish with the 0.3μm film before a final finish polish with Autpsol paste. All worked out well.

​

Ren wax was then applied to reduce any possible oxidation.

Plus US$20 shipping from the US makes it AU$45 total. Not cheap. Mine cost AU$8.50 including shipping.

Anyway, this post is not about alternative sources, just what I did with my purchase.

I think I paid about the same for mine, which didn't require all the extra work.

My point was, while sometimes it will be necessary to modify a tool we have on hand to get it to do what we need, usually because the job needs done right away, it is always better to get the right tool for the job if possible.

You might be happy spending a whole bunch of time and effort trying to turn a cross peen hammer into something that sort of works as a ball peen, but most of us would rather have the correct tool when it it is no harder to get, costs less, requires no effort, and will give a better result.

This is precisely why I started the Aussie/NZ section, so people could ask about sourcing local equipment, services, supplies, etc. It is a resource that is woefully underutilised.

Have tool box, use ball pein thats in there, its small, had it years, just wipe it on me pants, none of this polishing rubbish.
I normally aneal pins 3 times then bash their heads in with a small standard tool box ball pein, it works.

For nearly a decade I used a square faced tack hammer and always got compliments on my peening. Had the most messed up face you ever saw. Probably what caused the pin to mushroom! Like a miniature meat tenderizer.
From the dollar bin , way back when at the local Ace Hardware store!
Stupid thing works great. I’ve seen smoother rocks. I’ll polish pins and razors, not hammers.

Ya cracked me up wombat!

$10.00 tool and $20 shipping doesn’t add up to $45.
I’m sure there are hidden costs I’m not aware of.
But instead of a cross peen and you have so much time why not regrind it to the actual shape you need?
Sorry to say I have no clue and really doesn’t matter to me what the weight of my hammer is. I just adapt.
And by the way the extra protection of the Ren-Wax is probably gone the first time you use it and start whacking pins. Most polished surfaces have much less chance of rusting .
Just my take on these points and probably wrong.

Yeah, with the number of mistresses you claim to have, I'm not surprised!

Ah, such a shame. Let me pour you another two fingers.

You failed to read the AU$ part of my post. That stands for Australia dollar. Currently AU$1 = about US$0.67.

I did regrind the cross pein into the shape I desired. I thought I explained that in my OP.

The Renaissance wax is applied to reduce oxidation between uses, not during use. I reapply it after each pinning session.

@Wombat ESQ and @mycarver, of course what you say must work very well. I am probably over thinking things by wanting to use a mirror finished surface on my pins when mushrooming them. Probably part of my OCD.

My girlfriends are all well educated, employed and self-supporting; accountant, nurse and engineer.

I do privately sponsor an orphan through high school (and later probably university) in the Philippines but she is not one of my girlfriends. I believe in helping worthy people where it is within my means. This does mean that I must go without some of my material desires in life but I feel that small sacrifice is worth it to help another. There are some on B&B who disagree with such benevolence.

It works, before wiping on me pants, and after wiping on me pants, its so pretty, like a redneck with three teeth on her prom night.





Call it OCD? I call it Peter Perfect, I once strived for perfection until my Peter Perfect sister died, her brain killed her at fifty, it was always worrying about the one millimeter out of square in two feet, for crying out loud! My attitude became more relaxed over the last 20 years.

It's great you have a razor peining hammer, I grant you that. I'm not peining hundreds as I'm into straights, DE, SE, Unusual, Curved, Ladies, or any I like the look of, therefore my peining hammer must do other jobs in the interim between razor pins, to have a specialised peiner defeats any budgetary constraints, eg; owning two hammers? despite the fact one may have several, but you may get the point? This gem of a mules armpit probably does nine dark alley bashings to one peining? Weight? irrelevant! you tap tap tap whether its fifty grams or two pounder.

There are always nine ways to skin a cat, eight of those work well, one does not.

I've often thought of making a G clamp style adjustable double shafted spinny thingy that would make the pins dome headed like a hot formed rivet, but a hammer it is for the foreseeable future until i get a lathe on the twelfth of never.

I love how a lighter hammer can bounce. You only have to deliberately make a strike every third or fourth hit, but the hammer is stil working. best tip is get the pin to the right length and filed flat before peening Always keep a 6" mill bastard file handy. use it to flatten the pins and if the pins are too long, you can still file some off. There may be files that are better suited to the task but the 6" mill bastard is universally available cheap. Only use this file on brass, metal files used on steel previously, struggle to cut non-ferrous metals well.

 

[mycarver]

Huh. The things you do are the exact opposite of what I look for or want . And are the things I don’t want and can’t control.

 

[Gamma]

I use one single 4" mill bastard on brass, steel, and nickel silver pins. I use the same file on all materials actually; plain steel, stainless, copper, bone, wood, plastic, etc and it works great on everything. I use a wire brush to clear the teeth, might chalk it if the material is very soft, and it has no issue going from steel to brass or whatever and back again.
