I have just fabricated the frames for my tender. Now looking to make the horns, Reeves can supply the casting at £96, this is to steep for me. Can anybody suggest a suitable method and materials to fabricate horns without using castings ?

I made mind for a 3.1/2 tender on my CNC mill. Pretty easy really, milled in one operation out of 1/2" steel.

You tube has Mr Crispin making hornblocks for Springbok somewhere I recall. Worth a look.

Phew! priceof castings seems to rocket.

Could you fabricate from ,say, 1/2" x 1/2" x 1/8" steel angle and silver solder in any necessary triangular webs. A bit fiddly, but cheap.

Alternatively, horns for other designs seem a bit cheaper, eg those for my 5" Priness of Wales are "only" about £65.

Any scope there?

Hello Peter, fabricate them from 1/8" steel angle and save yourself around £85. The picture below shows those that I made for the tender to my 5" Salisbury. They took me a couple of hours to saw the pieces for all 6 and file them to size, and an afternoon to silver solder together. I made a simple jig to hold the parts together while heating or the small pieces float on the molten flux 😄

GLR have pictures of many of their castings on their site - the GWR ones for the Keith Wilson 5" Mogul come out about half the price.

Oh well, it's adrift somewhere out in the ether, check your spam folder though.

Here's the support piece, angle has two pieces of titanium sheet angle bolted to each end which supports the horn angle piece and is solder proof. If you don't have any or can't find any locally, PM your address and I will post you a piece. Not shown in the picture is the hold down which was a vertical bar with a guide piece at the top through which a piece of pointed stainless steel rod passed and held down the small gusset pieces.
