Thread: Loose Pivot Pin Repair??

I have a few vintage 3 pin razors and none have these new type pins. The same holds true for my vintage 2 pin razors. I can only assume, admittedly I should not, that vintage razors with these new type pins were assembled from left over original blades and original scales or re assembled after cleaning with these new type pins. I would really like to know when these new type pins came into common use. I am doubtful they were in use in the 1960s-70s. Anybody know this information?

Purley done for faster production,I would bet with pneumatic punch.I hate them.

Yes, that is what I think also. Would you be suspicious of vintage straights with these new type pins installed?

I think being a mass production technique, you would not see Vintage blades pinned that way,Dunno

Getting the pins is no problem, I have had some a couple of years ago from a Canadian vendor. I cut the heads off and used them in the more traditional manner of pinning.

Yes, I have seen these new type of pins on what I would consider vintage straights but I would not necessarily think they were OEM at the time these razors were originally produced. I just have my doubts and would like to find out exactly when these new type of pins went into common use. Like I said, I doubt they were in use in the 1960s-70s on the production line.

Here is an old

video

of the Dovo Factory making razors. At 3.20 on the counter, is the pinning process, you can see the type of pin Neil is talking about and how gently and lovingly the pin is caressed into shape… NOT.

Although, she probably does hundreds, maybe thousands a day and has the touch down to a science.

To the OP, Phoenix, this is not what we are talking about for your razor, too hard a hit will crack your scales, start with some light taps, see if it improves. If needed, a few more… until it will stay open on its own. use just the hammer.

Peen the left side as you are looking at the razor, pivot end up and spine facing you. You should be able to tell, which is the manufactured side of the pin and which has the collar, though it may have been re-pinned.

A properly adjusted pivot pin that will hold a razor open makes stropping, so much easier and safer.
Often, a few light taps will make a world of difference.

Revisor Solingen stock these abominations of the pin world by the bucket load, should anyone want them.

I have no doubt that you and your mate have seen old blades scaled up using these pins - we all have, so no point in futile PMs.

As stated before, old TI blades have been scaled using them, Revisors current NOS ditto, Revisors refinished period blanks, ditto, Revisors 'rarities of the world' - ditto.

There have been other makers, contemporary with Revisor who have resurrected old names and rescaled them using the new pins (my source for this info is Thomas, owner of Revisor) and I have little doubt that the apparently inexhaustible stock of european Dorkos, Globusmen et al. share a similar 'provenance'.

No, don,t waste time on PMing someone who does not know one way or the other when there are many other more fruitful and positive lanes of enquiry open...

Nice video, Euclid!

This video was released with another at roughly the same time. Yours does not have the publication info, but the other one states date of publication as 2011 which kind of fits in with that odd-looking cow-horn scaled Dovo featured in the video you linked to, which in relative terms is not that old.

With regard to the new vs old pins and Dovo, perhaps some insight can be had from Fritz Bracht who took over the running of the company from Dorp & Voos before WW2. Bracht had his own brand of razor before that - the well-regarded Tennis razor, and he shared a site and resources with Dovo for some time, running the Dovo works and running his own concern.

All Fritz Bracht early Dovos I have seen had the old-style pins on them. Two two concerns were merged into one in 1952, and Bracht's son-in-law Ernst Kirschbaum oficially took over the running of the company in 1953, so post 1953 Fritz Bracht Dovos and Tennis razors had old-style pins.

The information about when Fritz Bracht stopped having any input into the company is sketchy, and the fact that Dovo retained his name long after he was gone does not help much. So, for Dovo at least, we have a start point, but which still needs revision.

I have peened pivot pins ending up with warped scales. Even keeping the blade between the scales while peening did not prevent this from happening. Any advice how to deal with this problem?

I think you have to try and determine the cause of the deflection, possibly by using one of those mini threaded pins and bolts and tightening and examining what is happening bit by bit.

When I have had this problem in the past it was mostly due to either the rake set on the tang or a slight warp in the tang. As the pin is tightened it forces the scale to come into closer contact with the warped or raked tang, throwing off the geomety. Either allowing for this by sanding the inside of the scale to a certain plane or bu partially seating a washer in a hand-cut rebate to keep things parallel helps - but is a lot of work.

Regards,
Neil

Thank you for your observations, I will check my razors soon to see what happened exactly.

I have always thought that peening causes the pivot pin to bend slightly. That way one of the scales is pulled to slightly towards the tail and the other a bit towards the toe of the blade.
