Made this wooden supports to site pistons on when fitting barrels, this gives the ring compressor clearance to allow the barrels to slid down the piston without trying to support the piston under the skirt and just keeps the piston really steady and square, it made the job so much easier

Looks good.
As long as you don't try and make the pistons out of wood next !
