|Masokits RTR Springing Units - Keith Norgrove|
Mike Clark introduced these units at Scaleforum 2004. The picture sequence following shows my first attempt at assembling these. Click on the pictures for larger versions.
|The frets as supplied, the pack also contains 8 bearings and a short length of wire to peg the spacer bar to the spring units.|
|The parts assembled, no problems getting this far, just follow the clear instructions. For the stainless steel springs I used Fry's Powerflow flux (in the yellow tub) it does the job well.|
|Again follow the instructions, file the rectangular openings till the spring units just fit, just over 23mm between inside faces. Then ensure the insides of the W irons are smooth and parallel. The calipers help here.|
|Now the instructions suggest that you 'may' have to round off the pinpoints slightly. These pictures show that a standard 26mm axle splays the bearing carriers out to a little over 24mm and no way will it fit into the chassis.|
|I found it difficult to grind a new point central on the axle end so ended up with a distinct wobble. For the second attempt I cut a piece out of the axle so that the joint came in one of the wheel bearing sleeves. This technique was easier and fully successful.||Using an Exactoscale wheelset with its narrower wheels I reduced the axle length to 25mm by grinding off one end and making a new point using a dremel cutting disc. (See left). An alternative is to use the Exactoscale 2 mm OD parallel bearings.|
|With the short axles the spring unit assembles nicely into the chassis.|
|And the body can be replaced. The chassis to body screw fixings are lost in the process so a new mounting will be needed.|
