Hamish, we've all been there  Looks good though. Had a very similar experience once. Although fortunately on dry land!

Contacted my insurance & been to a local bodyshop. Said my name and that the accountant of my work (and TR6 owner) send me. 'Oh, then you rebuild his TR6 engine years ago etc and you daily a Spitfire' 🫣😅 Today will get more info. Not heard from the delivery company's insurance.. Will see 🙃

Ouch

Good old fashioned stuff... 

I've seen someone using a hack saw blade, a broom handle and some wire to make a TV aerial so they could covertly watch TV in a workshop, wish I could remember how they did it now. 

Looks like we're getting prepared for Armageddon ... better known as the Trump Reign of Terror BTW ... I remember making crystal radios as a kid using a gallium crystal and a roll of magnet wire.  As a kid I built an am radio receiver using two safety razors and a pencil lead for lack of the crystal. Similar to the FoxHole Radio. I also used a toilet paper cardboard tube wound with magnet wire and a hacksaw blade as a wiper on it as a tuning device.  

The chuck mounts to the drill press spindle with a morse taper. Under heavy load there is not enough friction between the taper and the chuck and so the spindle rotates while the chuck stands still. It's sort of like a a safety device. You can place a block of wood between the chuck and the drill press stage with about an 2.5cm between the two. Then take a brass hammer (  like the ones we use to take off wire wheel spinners ) and hit the top surface of the chuck while rotating is slowly. Once they part, clean the inside taper surface of the chuck and the spindle with brake cleaner and dry. Put a thin coat of lacquer on both tapers and permit to dry overnight. - Another option is to use regular thread lock and assemble before drying. If you use the thread lock, permit it 24 hours to set. Place the chuck under the spindle and now ram the spindle as hard as you can ( with the motor OFF ) This should last quite a while. Good luck, Steve

Last summer I converted the 8 Florescent fixtures. in my garage to LED. Not that my bulbs had gone bad but that in my detached unheated garage the bulbs dim at temperatures below 4C. Purchased the units from Costco which I understand as centers in the UK as well.  These are not replacement tubes but instead complete fixtures. My fixtures had 4 tubes in each. I gutted the inside of the fixtures and built the new units into the old housings. Though a lot of work, these are close to twice as bright as the originals. This is a link to an Amazon.UK page for similar units: https://www.amazon.co.uk/Amdelne-Daylight-Lighting-Linkable-Warehouse/dp/B0FC2VZL48/ref=pb_allspark_dp_sims_pao_desktop_session_based_d_sccl_1_4/523-6530361-7921466?pd_rd_w=IrmXO&content-id=amzn1.sym.3d2941c4-8dbd-4559-a2da-3450ec26a618&pf_rd_p=3d2941c4-8dbd-4559-a2da-3450ec26a618&pf_rd_r=EV47Q1F5HV2PG1W8X9D9&pd_rd_wg=KuNjU&pd_rd_r=b2f9df67-0964-4087-8e8a-36704cb1fc86&pd_rd_i=B0FC2VZL48&th=1

I might suggest that your competence level is fine, after all you successfully installed said wind vane, looks pretty sturdy and rather importantly appears to be straight. It would have functioned fine. It's your eye for detail that loses you marks. But seeing as you also own two rather impressive cars, I suspect you aren't going to miss those marks overly much. Without wishing to deprecate Nick in any way, men admit mistakes whereas fools pretend they didn't happen (usually causing a large workload surge for everyone else). Brings to mind a certain numpty of a 3/E I had the displeasure of sailing with a couple of years back, who thought that pressing the centre indicator on a 440V 3-phase contactor was how you test the overload trip on a very large motor.............

But non of that merry band of illustrious folk can go as fast as the greased weasel
