Roxey Summers Iron Ore Hopper part 2 - Bogies 1.

The bogies consist of an etched frame with whitemetal sideframes. All very straightforward really but there are a couple of points to watch for.

 

When folding up the frames there are some inner striffening ribs to fold down after the sides are folded down. (I used a 2" Hold & Fold for the sides and a pair of square ended pliers for the ribs). If the ribs are just folded as they are they will splay the sides out so a file has to be taken to the edge of the rib that will butt up against the side, arrowed in the photo;

With the bearings in place there is too much axle slop, easily remedied by inserting a thin 2mm washer (Gibson) between the bearing flange and sideplate on one side only. Bearing holes, etched quite a bit undersized, were opened out with a 5 sided broach before the frames were seperated from the main etch.

 

The etched holes in the sides don't match the cast holes in the w/m sideframes;

A bit of (not too pretty) filework sorts things out;

To hold the frames whilst filing I used a small hand vice;

Sideframes will be glued in place later on, after I've fitted mounts for tension lock couplers (not included but I have a plan...).

 

All soldering was done with an Antex XS25 using 188 degree solder.

Hi Paul. That hand vice looks sturdy and good quality. Can I ask what brand it is?

The hand vice is unbranded I'm afraid Mikkel. I picked it up at an exhibition last year but I can't even remember whose stand I bought it from. Its reasonably good quality, apart from the wingnut being rather stiff, and, most importantly, the jaws are smooth.

Eileens stock a similar vice: http://www.eileensemporium.com/index.php?page=shop.product_details&flypage=eny_fly_default.tpl&product_id=4971&category_id=137&option=com_virtuemart&Itemid=9 . I haven't had my hands on one so I can't vouch for quality.

I have one like that and, like yours, the wingnut is very stiff. IIRC it came from expo so it's probably something that a lot of people stock. I don't use it that often as I also have a couple of small toolmakers' clamps which I find more versatile and easier to adjust.

I reckon that the stiffness comes fom the rather coarse pitch of the thread, a finer pitch would I'm sure smooth things out.

Thanks Rich.

 

I wonder if the etch is just a straightforward reproduction of the 7mm version or if it has been tweaked in some areas? I shall ask next time I see Roxey at an exhibition.

Yes i reckon it most likely is just a repro of the o gauge etch, tweaked maybe thou don't know any o gauge modellers who have a big ici hopper maybe a member would know?
