I recently Picked up a partially complete Horwich crab to Don Youngs design and was wondering if anyone else is building one on here and if there are any Bits to take care with or errors on the drawings? I have also got a number of parts to be laser cut if anybody is interested to enable assembly with ease .
As arrived the frames where assembled using small cap headed screws and also lacked the holes for the horn keeps and Cylinder mountings so the frames have been split and are bolted together ready for drilling early in the new year on the Miller at work (DrRO Fitted) and then I hope to get on with riveting up the frames if i can source a suitable set of rivet snaps.

You can make your own rivet snaps in the lathe from a piece of Silver Steel using a ball nose slot drill of the appropriate radius if that's more convenient. They really don't need to be hard.

I've always made them out of silver steel, drill almost to depth with a drill slightly undersize. Heat to bright red and place it on the head of a rivet. A sharp smack with a hammer forms the shape. Harden and temper and off you go.  |

The Horwich Crab is generally reckoned to be one of Don's best designs - possibly because he didn't design it! It's attributed to the late Norman Lowe, who was an ex Horwich employee. Don just re-drew Norman's drawings and published them. Norman's original Crab, now in new ownership, was running at the Southern Fed spring rally at Kinver - a real beauty to behold. Yours could be an interesting build thread - any photos?

This is off topic but related by name , I am considering to build a Crab but mine will be the American Crab , I may do this because I have a vertical boiler that I built many years ago for stationary engines but never used for that purpose and this engine does not require castings , so I can use whatever I have on the shelf . Anyway snaps are easy to make to suit the rivets as explained above . I am sure you will have no problem making them . Making them will inspire you to make other special tool as needed in the future , go for it .

Might I add that Hexagon stock is non-slip in a 3-jaw chuck and easier to hold when in use.....

Not so much an eBay find. It actually came from a friend of a friend, complete with the coupling rods done too , as a devout 7.25" narrow gauge man I fancied a fresh challenge and this came up at the right time. The plan is to get it to a point ready to paint the bottom end and then wait to buy a boiler.

That looks like a good start to the project you have there.. look forward to future build updates.

Many thanks.........So THAT'S what my club track looks like !!....really must get down there this year...A 2-6-0 with a 6P5F rating and only 66 tons all-up and in the mid 1920's as well, what a beast indeed !!...( and YES, I looked all that up in the Ian Allan book..)....You can see the same Fowler design team at work there that gave us "BIG Bertha" as well ( en.wikipedia.org/wiki/MR_0-10-0_Lickey_Banker )......and this ( www.youtube.com/watch?v=ja1gPyIszqc )-------------- and I thought you might like to watch this..Look out for a Rotary valve engine passing qickly through ( www.youtube.com/watch?v=rXD659VTJvg ) |

i do think the Horwich Crab is a most beautiful loco! don young corresponded with stuart cox for many years, so when norman lowe decided to build same it resulted in don's E.S. COX design. don acknowledged norman's input in same. stuart cox actually checked don's drawings first. it is also a wonderful performer in miniature. the full construction series is in LLAS. don had of course designed his L&YR LANKY on another norman lowe miniature loco previously. norman lowe also produced all the patterns for the replica fullsize SANS PARIEL. stuart cox was a junior draughtsman at the time at Horwich, and almost single handed designed the Horwich Crab!
jordan if you pop down to Reeves ask to see the castings. not many have been built of this design and you may find some that are the ones don young had which are quite superb. i remember seeing them in don's 'garage' at adgestone - supposedly to keep the Bentley in but was full up with castings meticulously arranged!
cheers,
julian

Many thanks folks i will indeed try and get to reeves when i start to order more bits can anyone confirm if the Pony truck bolster was originally a casting. reeves dont have this listed and being a very intricate item i cant see any way of producing this

jordan,
you really must get don's 'words and music' from back issues of LLAS. it is quite a detailed construction series.
cheers,
julian

Hi Manny, I will send you a private message but I am looking at producing a few patterns for lost wax casting for the Pony bolster and spring hangers if you would be interested
