Now that certainly looks like a beast of a boat Doug,
what size is she, really looks good on the water👍👍
will look forward to the blog history, don't leave it to late😊

Cheers, Pete

Ooops

Here is a diagram of the hackworth gear😊😊

"you must a'v been nowt but a lad."
Correct Pete,
I started the project when I was 13/14. Hotspur's Maiden Voyage took place on my 15th birthday August 1966 in the boating pool in Radnor Park Folkestone. We went to stay with Granny & Grandad in Folkestone (where I was born😉) every summer.
I'll put the rest of her history in a Blog or Harbour entry some time!
Cheers, Doug 😎

Apologies Doug, 😧that's what you get for reading to fast and not paying attention, funny that's what my teachers used to say🙄.
53 years ago! you must a'v been nowt but a lad.

Cheers, Pete

Those were the days you could post a letter!

Wot?
A Blog 53 years ago!?
Wouldn't have got many likes or replies Pete!🤔
I've just posted a few bits of her over the last 2 or 3 years, when they were relevant to someone's query. She was built from plans I drew up by measuring the Airfix 600 kit parts with a micrometer! Was doing Tech Drawing at school 😉 Had to multiply everything by
8.3333333333333333333333333333333😮
😁😂😎

Must have missed that one Doug, will have another shufty, but your scratchbuilt one looks very tasty👍👍

Cheers, Pete

btw, Did you ever do a build blog on your Hotspur?

What about the 1936 H class destroyer?
Like my HMS Hotspur H01 which I scratched to 1/72😉
(About 53 years ago🤔)
Cheers, Doug 😎

Some very tasty looking warships in the Fleetscale catalogue Doug, could one of these be that extra to the bakers dozen!😊
The only problem is that they are all a bit modern for me, apart from HMS Cavalier which can be made as an earlier version than the 1960 plan that comes with it.

Cheers, Pete

Thank you all for the posts and help.
Rick

Here you can get a 1/48 hull and plan for Turbinia😊
Guess 1/48 might be a bit narrow though🤔
The 1/24 plan works out at about 4feet x 4.5inches.
Cheers, Doug 😎

"still looking for a plan for the boat it will be a launch"
Hmmm🙄
How about this? Fastest boat around in 1897😮

Would make a fine model and unusual sight on the pond👍
Not essential to build the turbines😁😂🤣
Cheers, Doug 😎

Looks like you're in very good hands now Rick👍
Guess I'll take a back seat now, sit back, watch the fun and LEARN!😀
Good luck, Cheers, Doug 😎

Your right in testing the engine as I have done just that.Running in the engine on air at 30 psi shifting the lever up and down to test and set up.
Rick

Good idea with the run on compressed air. Also take note when setting up the servo on the timing block that has the 3 screws and the location to the off position. The square of this block should be square vertically and horizontal. Plus you can do a final calibration to center off with the trim tabs on your transmitter.

Try putting some oil in cylinder inlets and let it run on compressed air as a bench test. This will show you where the reversing lever needs to be for fwd rev and neutral. Just an idea best to bench test before you put it in a hull👍👍 By the way they are sometimes called a Johnson Bar

Okey dokey,
Keep us in the loop Rick👍
😎

To give an update this will be a new build still looking for a plan for the boat it will be a launch.I can figure out were the servo will go in the building of the boat.Still looking at a boiler and gas to put into the boat .
Rick

I have the Graham TVR1A. Had it for years and have a paddle wheel launch that I am building. Looked at the engine and what I would do is to remove the lever that goes into the slots and come out the other side (the block with the 3 screws are and that the center one is used for the lever). You can make a right angle bracket that uses the center screw to hold in place (may need a shorter screw). This right angle bracket Would have a twist for a right angle to connect to a servo rod.
There are many ways to do this, but I would work from this timing block side.

See attached Photo The valve motion is driven by two eccentrics one for each cylinder which feeds to a slide and a block(per cylinder) that connects to a valve block with a sliding valve inside the valve chests the pivot position is altered slightly and is controlled by moving the position of the slide assembly this is moved by the link in the front. this is normally connected to a lever known as the reversing lever this has to be notched into a position or the steam will move it for you. The forward and reverse lever you are talking about must lock into forward reverse or neutral. Good Luck👍👍

Oh by the way the lever has to lock in position whether forward aft or idle

Hi Rick
If I remember rightly the engine you have is actually a stationary twin cylinder vertical with hackworth valve gear (It has sliding blocks and pivots) The lever will need quite a heavy servo as you are trying to move the sliding inlet valve to a different position on the valve block and there is always pressure there. I will see what I can dig out some info on hackworth valve gears but as to the installation not sure. (Ex Model Engineer)

Look forward to that Rick.👍
Don't forget to show how the engine, and boiler gas tank and any other necessary gizmos, fit around it.
Then we can see where we might be able to fit a linkage.
Cheers, Doug 😎

Thank Doug I will take some pictures of the engine and post them.
Rick

Hi Rick,
I'm a dunce when it comes to steam engines, and gobsmacked by the machines some folks can build. 😮
But servo linkages is more my game, so if you can post a photo(s) of the engine showing the lever, and how the engine sits in the boat, I'm sure we can work something out👍
First thought is to use a linear servo, but need to see how the lever moves.
Cheers, Doug 😎
