    Identify the thread of this screw from my boat

    I know 3/16 is 0.1875 but thought #10 is 0.19", I think someone once told me there was a difference and a nut for one size might size might not work properly with a bolt from the other size (or vice/versa) even though there's only 0.0025" difference. I've also seen charts showing the #10 is...

    Identify the thread of this screw from my boat

    Thanks for the thread info. I knew Sir Joseph Whitworth helped standardise imperial measurement threads in the UK in 1841, BSP pipe threads are still commonly used and based on the Whitworth standard. I didn't know that in 1948 the UK, US and Canada agreed to use a common standard (the now...

    Identify the thread of this screw from my boat

    Sorry to mess you all about, the tpi pic above is misleading, my mistake. I just took 2 more pics... Caliper set to 1cm (10mm). It seems Scott is correct I had the caliper set to 1cm. It was a few days ago when I took the pics and I'd forgotten what I had it set to, I took a lot more pics at...

    Engine dieseling

    Seems to me one or more of: ignition isn't turning off properly hot spots in cylinders due to carbon build up plugs getting too hot (fouled / wrong heat range / over advanced timing) low octane fuel

    Boat cover for FourWinns Sundowner to use when towing

    I just called my dads old friend. He's been retired several years now but the company he started a long time ago that makes industrial machines is still doing well and he's still involved with it. I only called him for advice about buying an old sewing machine and how to sew canvas. He said...

    Boat cover for FourWinns Sundowner to use when towing

    I didn't expect to get a new one off a shelf but thought maybe some US manufacturers keep drawings / dimensions of covers for old boats and could make a cover to fit as good as the original. I'll phone around more canvas shops but last year when I enquired they all seemed to have waiting long...

    Boat cover for FourWinns Sundowner to use when towing

    My '95 Sundowner 205 (believe made in 2006) has a green canvas cover for use when trailering that clips to the boat using press studs around the bottom of the screen and down each side of the boat, it uses elastic clips to tie to the rear of the boat. Around the edges of the cover where the...

    A lot of H in LPG / propane so when you burn it you get a lot of H2O. I'm familiar because I convert vehicles to run on propane, at this time of year when it's cold and damp some converted vehicle owners worry about their engines if they get more steam out the exhaust from a cold start.

    cooking

    I'm British and have to admit my favourite meal is a traditional roast dinner, beef / turkey / pork, roast potatoes, various veg, Yorkshire puddings, proper gravy. Fish'n'chips if they're good quality and cooked right, Indian curries such as Vindaloo. Enjoy barbeques but they're usually simple...

    cooking

    Years ago after a couple of takeaway chicken vindaloos that I thought were way too mild, the next time I used a different takeaway and told them to make me a chicken 'phall' curry that was as hot as they could possibly make it. After a few mouthfulls I was straight to the fridge to drink some...

    I had to Google 'Nosebag', I know a bit of Cockney rhyming slang but not as much as a Cockney / Londoner because I'm in the North a long way from London. Seems like the kind of thing that might be said in an old comedy series like 'Only Fools And Horses' or 'Til Death Us Do Part'. A stand up...

    Trailer wheel bearings - standard or stainless

    The trailer was made by MagicTilt in Florida, they gave me the list of parts numbers I posted at the top of this thread, out of the 2 seals you pictured the info they sent me says I need the 1.38" ID seal. I'm in the UK, not sure if the company who's website you got the pics from ships to the...

    2002 5,7 Mercruiser exhaust manifold keeps cracking - 5 times this summer

    I rebuilt my engine (Ford 302) because cracked exhausts allowed water into cylinders. Seems the water removes the oil film which leads to ring, bore and piston damage, rings had been overheated and lost springiness. Mine didn't seem to be burning much oil even before the rebuild but same things...

    Trailer wheel bearings - standard or stainless

    Thanks for all the comments, seems to confirm what I thought, I'll buy standard bearings. As said I won't be fitting new bearings straight away but do want to regrease the existing bearings. To regrease the existing bearings I'll need to throroughly clean everything up, which means removing...

    Swap wood panel in upholstery

    I understand what you're saying and it makes sense, yet I've applied several coats of the old timer mix which is 1 part boiled linseed oil, 1 part oil based varnish and 2 parts oil based paint thinner (turpentine substitute, white spirit) and it is adhering to itself.. Since that mix is 1/4...

    Trailer wheel bearings - standard or stainless

    For a trailer that gets dipped in seawater and freshwater is it better to fit standard spec wheel bearings or stainless steel bearings? It's my understanding that standard will withstand more weight and wear less at least if they don't get wet, while stainless shouldn't rust if it does get...

    Swap wood panel in upholstery

    I knew I'd forgotten to do something... Make the drain / vent holes doh! I've done that now, more of a faff making the holes with the old timer mix already on it than it would've been if I'd remembered to do it before applying the mix, with the mix on it it was pulling on the grain at the...
