    If you put an appropriately-sized rod inside the steerer then clamp on your old-stem-cutting guide, would the compression be enough to limit delamination while filing?

    Pivots of any kind are a hint that you should have used a database from the start.

    While importing into SQL Server you should normalize your data model (each field should depend on the key, the whole key and nothing but the key) then add appropriate indexing.

    If you use SQL Server 2016, that has R built-in.

    I'd use Powershell or LinqPad for this.

    Ideas bouncing round my head about building an L7e Heavy Quadricycle (Goods).
    Goods has a weight limit of 550kg, not including fuel (for EVs, not including traction batteries).
    Power is limited to 15kW.

    550kg + 158kg battery (~20kWh, using Leaf's density, wiht a 90% usable capacity threshold) +80kg driver + 20kg other stuff = 808kg.

    With a reasonable RR of 0.02, and Cd 0.4, area 1.2m^2, 60mph should take 10.3kW, 70mph should take 14.5kW. Range at 62mph would be 112 miles (not allowing for acceleration).

    Regs don't seem to specify what the requirements are for "Goods vehicle", but this might change the insurance categorisation. As an EV, VED should still be £0. To make an aerodynamic "goods" vehicle, I'm thinking pickup with a cover, so not brick shaped.

    Mini Mokes were about 550kg, and a dry A-series engine and box is about 105kg. Caterham 7 chassis are under 50kg.

    Feels doable.

    26mpg

    Brick-shaped and heavy? My 255k mile Transit Connect does 45mpg commuting.

    Riding deep crabon wheels through Stretford in black casual wear with no lights with low sun? Plus RLJ...

    Anyone had a Cervelo S5 black/red, white logo stolen? GF spotted one being ridden by an unlikely male in Stretford about 4pm-ish today. No helmet, not dressed like a cyclist, clothes all black. At a guess medium or large bike.

    Your guard needs to actually pass the widest point on the bridge for that clip to work.

    but I don't think the oven will pull more than 13A except on the pyrolytic cycle, so I'm not too worried, yet

    Resistive heating elements, just like filament bulbs, pass a ridiculous amount of current when they start up, before the heat increases the resistance.

    Went to watch a little of the NorthWestCCA round organised by Horwich Wheelers today.

    Rode my Minty Straggler, with its 750mm wide Salsa low-rise bars and Conti RaceKing 29x2.0" tyres. Probably had the most enjoyable ride of anyone there.
