Thanks to Velomaniac for the info . Tyre sizes were one hurdle to get over and it was tricky to decide what to get . I will have to wait and see what the post delivers and whether I can make it all fit on the wheels. I should get 1.25 tyres with standard inner 26 inch tubes .And I have realized that my biking "Eureka" moment was highly specific to me because:-
1) Our street has no (known to me) easily visible bikers although my wife maintains that she has seen a bike actually being ridden up here
2) Tales of "biking" accidents here are legion in our street , even though biking is very popular "around and about".
3) The nearby local pedestrian pathways are very dangerous especially for children.
4) So to me it seems that if people up here , in this street , do have bikes then they must be hidden away in their SUVs and driven to the areas where they can be used safely.
5) But I am a small "old car" user and would not dream of lugging my bike around this way . And I so not use an SUV or big car for bike transport.
6) A few days ago I came up with "walker lugging" (lifting/carrying ) my bike around (the hard way) to get around these dangerous roadways . Though , of course, by the time I had thought of this , I had forgotten the details about the bikes I actually owned! My bikes have remained largely , but not completely forgotten , in the shed . This was until I started to "get out" of my car and explore the detail of where I lived by walking (very gingerly!) around the neighbourhood, just "one step" at a time.
7) "Stepping up to the plate" after my "Eureka" moment :- And , recently I have also realized that care was needed with buying stuff because the type of bike dealers who sold me my "best bike" for £15 in 1970 no longer exist . They were generally very reliable and usually wore some sort of button up light brown overall cum coat ( but without any leggings).
After my biking "Eureka" bike moment occurred when I realized I could do some bike "lugging" ( just one step at a time) to get away from the dangers specific to "our street" .By doing this I found out that I could use the hidden back streets and byways that would lead me to the "golden" old railway infrastucture tarmacked pathways that go to and through all the main local scenic areas and tourist hot spots . Of course ,the Vikings used to lug their boats over the "difficult" river stretches so they could trade in places like Constantinople Well , my "bike lugging" will not have to be as hard as that but I will still have to take it at just "one step at a time" ( especially up and down those stricky "step" bits)
9) My Hercules Hustler was bought second hand around 1980 for about £20.00 and the wheels are not original . This bike did not really replace my earlier second hand "sturmey archer"3 speed "Raleigh" bike that had been stolen .But now as my interest in it has increased a quite a lot a I have figured out a use for it and so I have tried to find a "You Tube" Hercules equivalent to get the ideas needed to restore it a bit . However all the "You Tube" videos of bike workshops seem to be much too neat and tidy .The nearest "You Tube" equivalent I could find for a Hercules was a French guy who was doing up his Hercules in his grandad's workshop . And clearly he could do "clever stuff" like brazing ( I think) which is beyond what I have ever attempted .The condition of the wheels I have is OK though the rear wheel appears to be new and better . It has an alloy centre stamped "M" MAILLARD manufactured in France 38 -8 . The wheel rim has a special grooved edge and is stamped 26 by 1 1/4 O 597 10 3. So somebody at some point put some money into it.And I have some other small things to find out :- The rear wheel has grey paint under the rim tape . Is this likely to be grey cellulose primer or something special ? What paint can I use to restore it? The rim on the front has one small ding but appears to be otherwise OK. After a "think" - I decided to "copy" the cellulose trick and apply grey primer on all 4 wheels in these wheel rim inside areas.
10) The old tyres on the bike were well "documented" on the tyre sidewall as : Semperit : Made in Austria : 32-597 (26 inch by one and a quarter -this was also helpfully written on the tyre, so I know it must be true) . These Austrian tyres seem to have survived slightly better in the shed than the Japanese 27 inch ones on the other bike which split right down to the canvas . With these the splits in these Austrian tyres the splits did not go right down to the canvas ! ( but I realized ,even so , that "supergluing up" the cracks would not do, so I sent off for new tyres and tubes!). And the other thing I have noticed is that the 27 inch wheel size is not as popular as it once was (I think) . This confirms that the Hercules is the bike to spend the money on .
