Any question answered...

With the standard heavy-duty cutting wheel?

Wonder if the neighbours have gone to sleep yet...

it only sounds like a dentist drill neil, not a chop saw :)

Ha, It'll be a maxpowered dremel.

I was using the angle grinder for much of the afternoon to cut out old pipework, I do try to park the power tools at 5/6pm.

Supercharged, side-exit exhaust, of course.

petrol driven then?

I thought you meant it was going to pretend to have a job and scrounge beer off you

lol

you know what I mean

Indeed I do.

I have a copy of that book 'bicycling science' which is an interesting read, should you want to borrow it sometime.

(not a dig, just thought you might be interested)

do what?

I know science, I just struggle with terminology.

Brixton cycles use knipex cable cutters and suggested them over shimano or park tool.

As they had none in stock they had no vested interest in the suggestion.

Knipex are the best. What the pros use.

Fluid dynamics is a big word.

£45.85 from Parker, ah well- if the Park ones explode I can get some Knipex ones.

Enh, for the rhinovirus stuff, maybe, but I need leaflets on why you should wash hands, blah blah.

When do you need it by & what level of knowledge are the recieptients? I am meeting my infection control team in the morning & can see what they have electronically & email it to you.

You can find the knipex ones cheaper from hardware outlets.

Bike shops stick a mark up on them.

My point is, I am not saying that you know or don't know science, just that you might enjoy the book as you're interested in such things.

I also still have your chain(saw) by the way.

you can keep the chainsaw, some neighbours might need scaring in the future. I'll look into it. I usually just read books on WW1 naval warfare and such.

Trains, planes and such.

Much thanks to everyone who offered advice on the previous page, by the way. I'll look into manwithvan in case it's more suitable than 6ptwithcar.

For cables? I had wondered about doing that as I have been using the dremel to do a few bits and bobs.

Which cutting tool do you use?

Just the regular cutting discs. Nice, smooth cuts.

Avoiding boundary layer separation which is easier with turbulent flow than laminar, innit.

exactly, cos it causes friction and shit

It's not so much about the friction. A turbulent boundary layer wraps around a cylindrical/spherical body a bit before separating, which reduces form drag -- which is generally much larger than the skin friction. Making the body surface rough (or dimpled like a golf ball) to encourage a turbulent BL would increase skin friction, but it's worth it to for the substancial reduction in form drag.

But that doesn't mean you always want turbulent boundary layers, It just depends on the best way to avoid flow separation. I'm not sure not much this really matters when it comes to bicycle paint, but I don't really know anything about bike aerodynamics.
