The common complaint of remoteness from suppliers is becoming appropriate to more and more things, even even ordinary domesticalia apart perhaps from food and cleaing products… assuming the nearest nebula of supermarkets have not destroyed everything else with ten miles of it.
One aspect that may be worth investigating if you are in a club is sharing larger-scale purchases, provided all those involved accept that this may result in turning more electricity to swarf from over-sized stock than if able to buy the finished size.
Similarly with consumables like oils. Indeed that could even be a service to members, selling refills of their containers at a small profit to the club.
Share purchasing if you can, if buying small items like tools. If you are placing an order for a bof of carbide tips and and a vernier, ask if anyone else in the club wants anything from the same seller. Be careful not to be lumbered with a workshop-full though!
Bear in mind how and where bulky items like 25l oil drums and long lengthsof steel will be delivered. The supplier won’t thank you for expecting a blooming great lorry to navigate a cramped housing estate: he is used to visiting properly set-out factories.
Don’t forget that although the finished dimensions on a mild-steel component may be to fine limits and surfaces, it may be possible to machine it from hot-rolled material, and there your choice of suppliers may be larger by retailers to builders and farmers.
I bought the steel for steam-wagon chassis and workshop’s travelling-hoist from such a stoskist, and ironically that is located in a small village in a very rural area some twenty miles from my suburban home! I did not begrudge the round-trip fuel, nor the cutting to lengths charges so it would fit my car – but I did ensure I collected the bar ends which after all, I had bought as well!
B&Q sells only a limited range of steel sections, and aluminium sections and sheets; not cheaply, and the steel’s quality is better for its intended areas of use than for precision-engineering. It can be used but you need measure its nominal sizes carefully: the ferrous-something rod labelled 6mm diameter, was actually 1/4″ – and had coarse drawing-ribs along it. I could still use it, but with some additional care.
This does show that sometimes purchasing by personal collection may be the most economical way. No-one says it will be cheap whichever methods you use, but if collecting personally might cheaper and simpler than arranging a delivery. And it will arrive intact, on time, at the correct address!
The more difficult materials: cast-iron, copper alloys, small sections, fittings and fixings, etc., and specialist tools, were probably never stocked locally to most model-engineers.
How far would you expect to travel to collect? Only you can decide that, having regard to the nature of the journey as well as fuel cost. You might be able to plan the journey within another to reduce the miles, such as a holiday or visit to some point of interest, or family.
The furthest I have driven specifically, and back, in one day; was from South Dorset to near King’s Lynn; but that was to collect lathe spares as well as materials, from a private seller reducing his collection. (The seller had advertised on this Forum!)
In the end… Use “Our” Retailers, keep them in business.
