Searider Flooding Hull block
just thought id post these, basically its a Nylon 100mm dia castor wheel, (these are a good interference fit) used the Pillar Drill to mill it down flush and inserter a plastic drain thingy in it to drain any water that does get in.
i used rubber bungs for the front with a stainless bolt and washer, glue and clamp it up, this system can easily be removed if reqd to,i know its a bit of a dull subject but there have been quite a few versions of a flooding hull valve,and this does work very well,as used on my last one.
