yep put either bolts or strips of metal between the spider gears and weld it solid

Rather than trying to weld the gears together I just welded the gaps in the spider gears and side gears so that there was nowhere for them to go when they turn. much stronger IMHO. I have ti out at the moment so if youwant a pic let me know and I will take one before I put it back in.

you won't get it any stronger than welding the spider gears with strips between each one and weld it all as one solid lump , if you weld it so there is no where to go when they turn
you could find yourself looking for a new housing as it might burst the side as they try to run over the welds (happened to one of mine).
weld it solid so there is NO chance of the gears moving it will not break , you'll do a crown wheel or pinion before the gears even think about moving

my rear was a weld round the side gear to the side plate on one side, then fitted into the centre, then a weld thru the inspection holes in the crown wheel...that lasted 4 yrs..my present one has the side gear ground off, and the whole centre filled with weld..it aint going anywhere 
I think if you increasing power, lowering gears and fitting bigger tyres, then more strength is wise.. christover

weld all the way around the side gear in the main bit of the carrier, replace the spider gears, then put the other side gear back in the other half of the carrier, put the two halfs of the carrier back together.
then pull it apart, holding the side gear in the position it was in when it was together.
then weld it all the way around, and re-assemble.
now both side gears are fully welded and are still conected to eaach other via the spider gears and the carrier bolts.
even with one side of the carriers welds busted the centre still holds together and locked(this has happend befour, on 2-3 year old well used welded centres)
thought i had some pic's but i cant find em

I did it this way but left a small amount of movement in it. so that the tire would turn maybe 1/2 an inch.
DON'T DO IT this way.
This is the result of what happened to mine. mine are now all welded solid everything together.

thats right as i said in the beginning weld it solid or you'll be buying a new centre housing , if there is play it will continuely hammer away at it and eventaully walk over the welds popping your housing.

I've seen one diff locked by filling it with molten lead. It was a Centura diff used in a Torana sports sedan, powered by a Hemi. It never broke, but god it was heavy.
It should be easy for anyone to do, as lead can be melted on a stove top.

Just wondering would that method be rather weak? Even as opposed to completely filling the tooth with weld and grinding it back?

That's how mine was done. It broke.
