All the parts are now machined for the crankshaft of my Wyvern engine. My question is about the best way of joining them together. As far as I can tell the pins are a tight push fit into the plates but I dont want to push them fully home until its all aligned. Silver solder, Loctice 603, Straight knurl and press in, pinning are various methods Ive read about. Ime minded to loctite and maybe pin because once completed I guess the engine will be run for 10 minutes a year, no more. soldering may need further machining if it spreads too far and ide rather not. If I loctiite is it best practice to machine a shallow groove in the pin so there is space for it, especially if they are tight fitting? Any ideas greatly appreciated.

I decided in the end to use loctite and in stage 2 to cross drill and pin, again with loctite. Assembly in 2 stages. First the big end journal with a temporary main bearing journal that was continuous to keep alignment. A temporary spacer between the webs keeping them parallel. Second phase is to fit the permanent main bearing journals. A jig to ensure these are in perfect alignment and clamped is for today. Probably a piece of ground bar and parallels used in a temp arrangement. Thank to all for the various ideas and information on crankshaft construction.
