Mounted rails on dolly. The rails don&#39;t smoothly connect to those on the Aluminium frame and some thin metal shims were required to get the correct height. A metal support had to be placed above the Delrin pads to support the rails above the gap between frames.

&nbsp;

All side feet were mounted but extensive modifications were required to slotted feet due to them not being manufactured to drawing, and to Carme middle section flange width being incorrect (see previous entry).

&nbsp;

Removed brakes and started sliding CARME out. The dolly and the aluminium frame came partly separated as the weight of the side feet was shifted on the latter. Strapped them together. No damage.

&nbsp;

Kept sliding. Sliding when the carriages passed from one rail to the other was quite hard. The back carriage on the left looking downstream lost a single ball bearing when crossing over. A more sophisticated solution is probably required.

&nbsp;

Once Carme was on the dolly, opened it using M8 jacking bolts and lifted away front and middle section.&nbsp;

&nbsp;

No obvious damage inside but strain relief did not work as intended. Photos to be uploaded after more detailed inspection on Saturday.

&nbsp;

Plan to install right hand side detectors over the weekend. Unclear if bottom left detector is damaged and needs to be replaced.
