I am building an engine with two flywheels with fan blades instead of spokes for air cooling.It has caused me to make jigs to build them.The blades will be spot welded in position. I will use JB weld to create fillets at the joins and was wondering if the JB weld in a small spot will hold the blades whilst they are spot welded.Can someone recomend the correct JB and a supplier.

Yes you could put a blob mid width of the "spoke" and then tack the edges. It may get a bit too hot for it but will hold long enough to tack.

You want "original formula" in the red and black tubes not the rapid or marine

If its going to be welded then the filler for forming the fillets could be something that is a bit quicker to sand like car body filler, I tend to use the JBW where I need it's strength or heat resistance but UPOL filler for any cosmetics.
