Highslide JS

Our original design aim was to use fitted bolts when assembling the frames - the reasoning is explained in the design section of the web site. Once the frame to cast steel stretcher bolts were fitted, it became obvious that the some of the bolts were preventing the frame keep bolts from being fitted. In the image, the frames are upside down and the frame keep is at the top, itself upside down and fitted as a temporary stay. The 4 bolts each side of the hornguides marked "R" are the bolts that need to be replaced by rivets. On Saturday 29 August, Varley Boilers were on site to fit the rivets.

Highslide JS A set of rivets ready for installation. These will be cut to length once the correct length for the fitment has been established. Most rivets are 1-1/8" diameter and some are 1-1/4". They are a special materail to match the material in the cast steel stretchers. John says that the large rivets weren't easy to install!
