Any question answered...

how can i hold a carriage bolt like this to get the nut out? It's in a trick place where there is almost no leverage to 'hold on' to the bolt apart from pressing it down with thumb but it isn't enough.

You could tighten two more nuts to each other and loosen the one you need off. Then loosen all three.

A fashion photographer of mine has been getting really annoyed with his models re-photoshping his work and showcase their bad photoshopped results... he usually sends them a bunch of fair quality jpegs so they could have for their portfolios, nothing poster size but good enough for the models to mess with the files. So we want to know if there is a way to lock the jpeg files? We have tried saving them as PDFs and lock it that way but Photoshop can just override it. Simply locking the actual files to read only isn't good enough as it takes a 5 years old to work out how to untick the box. Any suggestion?

Watermark and DPI. Save sample files in low DPI so any work they do on the photos will almost always make things worse.
Why not just send them samples of already Photoshopped work? (If feasible) That way, any further work they do on it will be glaringly obvious.

If you screen shot something than the quality becomes bad, we are not too worried about that. I told him there is nothing he can do, but as a good mate, I want to ask around to see if there is anything I don't know. Thanks anyway.

He does, he sends them the final versions as what he would use for himself, but some models seem to want to add their own takes on the matter...

I say let 'em! from experience, clients post work almost always turns the photos into a clusterfuck. Why ask a professional to do it in the first place if you're gonna do nothing but botch it up later?!
Good luck to your friend, image copyright is a bit of a prickly one.

Anyone has a Bern helmet for salez (up to £30 Large) before I hit the buy button on the Evans website?

I am looking for a "cheap" allu track frame that supports a carbon fork. I will be riding longer distances (100 mile+ rides) with this as well as alleycat races. I don't have a lot of money to spend on it but I do wan't a reliable frame. There aren't many second hand frames available in my country (Netherlands). I hope to be able to ride on an actual track with it in the future (eventhough there is no track anywhere near my house at the moment).

Any ideas (and please don't say Cinelli)?

Dolan precursa

Yep. There's one locked outside a ferry port in Santander.

Any ideas?

Here's an idea; look at steel frames. Although the Dolan is plentiful and cheap, widening your search criteria can't hurt, and a steel frame will do all the things you list just as well as an aluminium one.

The Mrs has an steel Omega frame, fully chromed.

It's got (according to my vernier calipers) a 30.6mm seatpost in it, which goes so far but no further.

It's been cut off very short, I suspect because of this.

The OD of the seat tube is 31.6mm, but it's a mixture of fillet brazed and lugged from what I can see, so the OD gets a lot wider.

I cannot measure what the diameter of the section below the lug is, as my calipers aren't suitable.

Is there a question?

The old post was in roughly this far:

Shining a torch down in the tube there is no step- but below the lug the tube has clearly not had a seat post slid into it in recent memory.

Is there a question?

Best guess at the correct seatpost size?

about four inches in length?

Is there a question?

Nah, just an excuse for reflecto pron.

The current 30.6 is unwilling to go in any further. I could hit it with a mallet.

Or, I could get the seat-tube reamed to clean it up (surface corrosion is visible, although very minor).

Or, the answer might be "30.6? They never made them in that size, it's fucked throw it in the bin"

Best guess at the correct seatpost size?

OD of the seat tube is probably 31.8 (i.e. 1.25" nominal), wall thickness is likely to be 0.7 for single butted tube or 0.8 for double butted, so 30.4 or 30.2 seat post. I have a 30.4 you're welcome to try, just a basic Kalloy thing.

My laptop keeps overheating and suddenly shutting down. I hoovered the vents, but it didn't help. Looks like it needs to be taken apart and cleaned properly. Maybe even that is not a solution. Never disassembled a laptop. Any ideas what to do?

Thanks for the offer, let me see if I know anyone with a seatpost measuring tool first, when that fails I'll get back to you.

if the correct od of seat-post to seat within the seat tube is less than the id of the lug/collar, then will you be able to clamp the seat-post without additional shimming?

Dunno, I'm taking it up to Talbot Frameworks in the next couple of days for Matt to tell me what's required.

ryan has an awesome tool for this that he used on my alan, however my alans seattube was actually pretty fucked on the inside

My resting heart rate is 10bpm higher than normal, why is this?

Either coming down with something or you're tired.

Rest day today and its gone back to normal. Bonza.
