Have been using 2 lengths of right angle alli ex b&q about similar length to your strip and with thiner gauge metal works not to bad,  as a boy i used to use to 2 steel bars 1"x1/4" bolted together with piece to bend put in the middle then put in a vice, scrapy`s today are few and far between. What you say about muti bends i think really the problem i.e. depth beneath the jaws. Been looking on ebay at woodworker`s vices which i think may have the depth but still think some sort of former would be needed. What i will say is i enjoyed every second if you don`t try you don`t learn and there is also the hated thought of a paint job in the summer.

I agree. It looks very nice to me. 

Better than anything I could produce. 

Thanks for the update. Really enjoying following this restoration journey!

Nice brass work. I'm a fan of raw brass too. Paint hides detail and the evidence of some hard work. Look forward to it steaming down the track.

DSC02379.JPG Refering to the bending of metal i just found out B & Q sell right angle iron and used in conjunction with the alli  angle lets me keep a tight angle on the brass saves buying another vice and to a good extent solves the problem of multi bends i.e. cab.

DSC02387.JPG The reason  for posting these two photos is i was led to belive that wheels should be quarted or is that only in real locos?. Not quite at this stage yet but while waiting for brass i thought i would have a look and you can see the wheels are 180 degrees apart and run better backwards than fwd. so i think problems down the line. Paint striped the burner tank turns out it`s tin or steel me thinking it was brass bit dissapointed but i`ll get there

     Hi Ron,   180 degs is what they should be. The 2 drive wheels should have keys on the axles so the wheels can only be put on at 180 degs, this is the usual set up for single oscillating cylinders. Not sure what you mean about running better backwards than forwards though ?

Many thanks for that info regarding the wheels.  I should have corrected myself concerning fwd and rev i meant when pushing it along a desk there seems less friction in rev, i dissconected the con rods and the axles apear free enough i swaped the pistons but just the same so something for the future. It would be nice if i could make some sort of adaptor and try air, O K for guys who have bits and pieces but for i have to order.

       I understand now.   It is probably that if  you push the engine forward the pistons are pulling air in through the small steam hole causing more resistance [ as they usually work under the high pressure of steam], while in reverse they pull air through the larger exhaust steam holes. My Bowman 300's are the same. 
       Please don't mix up the cylinders and pistons, and make sure the pistons go in the cylinders with the conrods the right way round [ the serrated part of the hole facing in] or you will find that you will loose a lot of steam from the cylinders and it will not have the power to run on tracks.
