Oh bu**er!

Early indications are that there is a fundamental design flaw in the etched parts for this conversion :(

 

To be honest, I'm a bit annoyed with myself for not spotting and thinking about it earlier. The problem is that the cranked design of inner frame, designed to bring the axlebox into the right place, without having to mill down the bogie sideframes, doesn't allow the axlebox to travel high enough up the guide.

 

I've now got to decide whether I press on with what I've got, milling the sideframes to suit, or go for a redesign.

 

Whatever I decide, I have to make this work, not only because I'll be fed up with myself if I don't, I've now chopped up the sideframes into two parts - the main frame and the axleboxes still attached to the equalising beams.....

 

I guess that it was asking a bit too much that it would be a success first time.

Don't get too down heartened about it Pugsley, these things happen. It's why things like this are often referred to as the 'Bleeding Edge' of technology. Certainly the well known Deltic of Mr Pendenton was not at first a success. I think really, it's defiantly asking to much for something to be a success first time.

 

I'd press on with what you've got, but make careful notes as you do go. Then with the aide of those notes, go for a redesign of the etch pieces, with the aim to remove any other oversights that may well crop up. It's amazing what can occur to you when actually putting together bits you've made.

 

I'll certainly be following this with interest, if successful you may well cause me to attempt an S7 LMR Class 50...

I know how you feel no matter how hard you try to avoid it theres always a snafu. when I was detailing my shunter I ended up gluing it to my palm! Just keep at it even the best were beginners once

There's a challenge Matt - I like to encourage other people towards lunacy, so I've got even more reason to get it sorted now! ;)

 

I'm not too downhearted about it - I am a little bit disappointed that, with all the thought I'd put into it, that it does require redesigning. However, looking at it, and thinking objectively, I can do it with the parts I have, it's just going to involve more work. Rome wasn't built in a day, and all that :lol:

 

If this was a commercial project, I would go for a redesign, on two frets of different thicknesses, but it isn't, so I don't have to worry about that :D

 

Scots Region - Thanks - your gluing your shunter to your palm bit made me smile. I've never actually done that, although have had a couple of close calls :)
