Thread: Wedge for Aluminum Scales

I have some similar scales on a razor. I also have 3 one piece cast aluminum one piece(no wedge)

The wedge is aluminum, wedge pin is aluminum too on the one like yours. On The pivot side on all four are brass.

One of the cast aluminum looks like never shaved and pinning looks original also on the three. The one like yours, that I have, looks like non original pivot pinning. I suspect they were 'aftermarket' scales. The blank area in the center, on mine, has the initial 'H' etched in.

Figured I should add an image of the razors I mentioned. Although I only included one of the three top razors. The top ones are scale heavy, the bottom one is good balance

I have a similar set of scales on a Clauss razor. Definitely aluminum. They shine up like chrome with a little Maas and look great for months.

I agree the pivot pin may have been replaced but I think the scales are original. The design work in them seems to be very typical of Antoni Tadross; I can never be 100% sure though.

I just did a quick look at when Antoni Tadross was in the razor buisiness, and if those scales are origional to the razor, they are most likely a high tin alloy. During that time period, aluminum was still very expensive to produce, so metal smiths would make alloys of mostly tin to cut down on the cost.

Thanks for the info! Hopefully within a week or so I can figure out all of these questions and get to work.

It would be interesting to see exactly what these scales are made from. If the scales are original, and with worked spine detail, this may have been a premium priced razor from that time period and it may be possible they are aluminum. No disagreement, I'm just super curious now.

I was just about to suggest the same thing while reading through this thread. I think they are neat scales, but would not like scales this heavy. I would send pics of the scales to John (shutterbug) see what he could do with the design and keep the original scales for later. If I were to keep the scales I would use something lighter than brass for the wedge and more importantly I would make it fairly thin like the older wedges are. There is no reason to make those scales any heavier than they already are.

Just opinions take what you want and leave the rest.

Oh, just to point it out there is a magnet on most refrigerator seals.

RE: the galvanic reaction - the potential is there, certainly: it always is present with widely dissimilar metals, but it depends on the presence of an electrolyte to make it flow and take place. The electrolyte would likely be water or high humidity - the absence of either means that the reaction does not take place. Even for the brief period that a razor is used with water on it, the reaction is so weak that it would not be apparent - that is why these razors with metal scales, pins, wedges and washers have lasted.

Auto applications and other outdoor/indoor applications that are subjected to frequent immersion in water for prolonged periods (like winter time) are a completely different kettle of fish and the reaction will take place, leading to the eating away of the less 'noble' metal. Salt water makes an even more efficient electrolyte - salting the roads in winter enhances the reaction, for instance, and boats in water will lose steel parts unless another less noble metal - like aluminium - is present as an anode which gets eaten away instead.

I work in automotive, the next time you see a Land Rover Defender on the road notice how rusty the body capping is, usually not very. This capping is steel and the body is aluminium, however the capping is zinc coated which makes the contact similar metals. Also the capping is electro painted, the company I work for makes this part.
It is plated/painted for a reason, also as stated above an electrolyte would have to be present for the reaction to occurr.
In my experience my razor/scales (unlike cars) don't get that wet during use, so can't see this being a problem, niether do I keep rasors in the bathroom even without this added consideration.

I've checked the workshop wiki for the sources but I can't seem to find a vendor that might sell silver or nickel washers/pins; does anyone happen to know where I can buy them? (most have only brass or stainless)

I'd also be willing to buy from a member if anyone has some spares lying around.
