Having fixed the wheelbase, I then decided to add compensation - to test the capacity of the chassis jig (or, more reasonably, my ability to use it...). The front axle was modified to take 'High Level' hornblock guides & Bearings - and here the jig certainly proved it's worth. Normally I use axle-jigs which have to be removed to cut the guide slots etc. No problem here - the sides are just removed, adapted, then replaced over the fixed axles. All the components of the jig are 'solder-friendly' - either being resistant to normal solder or insulating tufnol (so no heat lost!).

Now it was time to assemble the chassis with spacers etc. The jig has a handy 'bridge' which can be used to ensure a square it for the various spacers -

a more distant view shows a handy device for casting light on the subject (£2.99 with your favourite fuel!) -

Once all the spacers have been added to one side, swap the short axle jigs for long ones,remove the sub-assembly, replace with the second side, replace the spacered sub-assembly & solder the unit together. Seeemples!.

The basic unit is now complete & just requires all the additional detailing one finds in a 'High Level' kit.

So how did I find the 'Chassis2Pro'? like the curates egg - good in parts. I liked -

The obvious accuracy imparted by the accurate spacing of the axle jigs.

The solder-friendly' materials

The ability to build the chassis completely on the jig with no apparent loss of accuracy.

What didn't I like?

The gap between the 'fence' and the tufnol base. This is slightly greater than the thickness of the etch material, so I had to tape the chassis-side down to ensure it was square to the machine.

the clips are really just an 'interference fit' with no positive location other than a thumb-screw to hold them in place. No problem on an 0-4-0 - but I plan to build a 28xx chassis next...

The instructional video is a bit long-winded with text overlays at irregular intervals. They don't really relate in detail to what is being shown in the video. There is however a 'pdf' manual on the CD which I printed off.

Will I use it again? At nearly £400 - you bet - its got to be made to work! Doubtless experience will develop the skills associated with using it - and I must find the 'MRJ' issue which dealt with it...
