It also has a little known anti-theft device, if someone tried lifting the trailer into a van/pickup the wheels & axle drop away making it immobile!

Great Dorset

Really was great this year, perfect weather and the engine ran faultlessly throughout.  Shown here on the Saturday evening in amongst the crowds by the line up of Showmans engines.  We ticked over until just gone 11pm then trundled back to base.  The lights worked well!





At the top of the play pen watching the big engines.

Had problems with the traction wagon again when loading it back into the van, the back axle dropped away when lifting it up.  The clamps I put around the leaf springs to stiffen them up had worked on the front axle (it's lighter) but the back axle fell away as the clamps just opened up.  Properly sorted now though, I've welded a loop on the end of the spring so it can't drop past the pin and fitted much heavy gauge straps to hold the leaves together.  

I'm working on building a heavy gauge tow bar for it as the  original although nicely made is a bit short and lightweight.  I find at rallies that when you have a trailer attached there's always someone wants a short cut across between the engine & trailer and they always stand on the tow bar.  I'm making one out of 1/2" solid bar and welding it to the original fittings apart from the towing pintle which I've cobbled together from my box of bits!  It has a large eye, rawl bolt with a bit of pipe, a spring from brake spares to give a soft start when pulling away.  It has springs built into the back of the dolly but they are pretty strong.  Pics when the paints' dry.

New grate

Post  Steve Traill on Mon 11 Sep 2017, 8:48 pm

I've noticed over the last few rallies where I've seen a couple of Road Loco's running about that they usually have quite a red fire in the ashpan burning away.  Also after Tim's work on building a Rosebud grate where there is hardly any ash left after a days steaming my crane engine has about two pan fulls.  Looking at the standard grate the bar spacing seems quite wide.
Also some of the bars were buckling a bit making some of the spaces even wider.  I decided to make a grate with a few more bars in (14 instead of 10).  Below is the old & the new, the new bars are 6mm longer at each end, there's still plenty of clearance for expansion and the same width.  The gap is 6.5mm with a 6.5mm slot for each 6mm bar so everything can expand & contract.  Hopefully I'll see a bit less ash as the coal is more thoroughly burnt before it drops away.  Time will tell!

Really shouldnt have fire both sides of the grate, apparently a sure fire (excuse the pun) way of killing a grate.

Another addition to the crane engine, most of the Road locos seem to have a small tool box attached to the side of the bunker extension, it'll be handy for the ignition system!



The 'H' Holmans badge is a small tribute to the company that fed & clothed most (over 2,000 employees) of the population of Camborne & Redruth for over a 100 years (including my family & I) and of which Tesco have removed virtually all trace.  I'm not sure if Holmans ever had traction engines, quite probably as they had their own railway and produced everything needed for hard rock mining from basic raw materials.  They were a one stop shop for any mine captain and had depots all over the world.  It's very sad that parts of our history seem to have no value.

A couple of tripod rock drills would make a great wagon load Steve.

That's true! BTW it's Holmans not Helmans, good one though!! I just googled Holmans Camborne & they employed 3,500 people in it's heyday and had been going for 200 years. When the population of Camborne is/was about 6,000 you can see they were pretty important around here.
