This might end up being a long and tenuous story about bring a very battered SQ4 back from the dead or alternatively a tale of defeat and give up! Right now it looks like a hopeless task with SO much missing but fingers crossed there are the missing bits out there someplace.
April 2023: Well not too much happened as had to move house after 38 years and it has taken the best part of 4 years to clean up the junk. The progress that has been made is mostly obtaining the missing bits and I had the head and barrel planned, new liners fitted and bored to suit the new pistons. and the cranks and mains ground to fit new bearings. In saying this I am wondering if a did a good enough job at cleaning ut those critical oilways in the crank - better look at them again after reading the technical article in this web site! The crank cases and barrel have been vapour blasted and quite a few new head studs machined in Stainless steel but quite a few to go - might end up buying some I think but the costs is eye-watering so we will see if I can get my lathe set up in a new house and do some more maybe.
New rims arrived, yet to spoke these but did make the Forma to do it which hopefully the packers did not leave behind as a bit of rubbish.
Soo all on hold now until we find a new shed with a house attached.
March 2024: Well now in the city of Napier. This house needs work done on it so nothing much has happened on this project other than to build a new bike table and gather some more bits for Chrome plating. This is not how things were supposed to go! Hopefully I can start on the engine once this woodwork is out of the way; there is just too much dust for engine building.
