Creating A Transmission Bolt Boss On An Engine

Cool man, let me know how it turns out.

You can buy machinable nickel rod. My wife sells it at her auto parts store. Forney makes it.
When I had the machine shop I've built up block corners and such with both nickel and 309 stainless. Used a plain old AC buzz box.
Done half a hole dozens of times. Small block chevies get starter boss chunks broke off fairly regular in these parts.
Back then I also brazed cracks and such on junkier cast with silicone bronze and used a cutting torch head. Prep, preheat, braze, post-heat, grind.
Now days we build up cast usually with silicone bronze and tig.
I don't seek out that work anymore but it still trickles in once in a while. mostly on inboard boat engines because we only weld on boats.
Those old Ford blocks were pretty good metal, so it should weld nice

Going to be another month before I get back to work on it. I appreciate it and will post my results.

Project suspended while I look to find a 58-60 junk block for a donor piece. If not I may just build a custom bell housing.

Started the build. Going to torque it all down and braise the cut off piece into the cut out slot. Would it be less prone to cracking if I was to run the engine up to temperature and braise in when hot or does it matter?

I think you should be able to get plenty enough preheat in that area with a rose bud, ya? I don’t think running it will get your pre-heat where it needs to be, but it will heat up the rest of the block and slow down the heat transfer.

Man reading through this old thread....I sure don’t miss that guy.....

I’d do some light peening too. Gas or TIG braze?

I too was really disappointed until I saw the date

Gas braze. Here is a video of what it took to bolt everything up. I'll know if my spot weld and braze held when I swap the NP435 out for a Clark 282V.

Digging up the dead man!

How’s goes it out there?

Are you just now getting back to it or has this been in the outbox just waiting for a cold February night?

It is going some way, put the engine in a month ago. Just dawned on me what my password was for this site today. Been back and forth between places a few times so now maybe this month I'll be able to cobble an exhaust together so I can make some long trips in it. I had the Brown Lipe shifter rods repaired like new. Been holding off on the Clark/Brown-Lipe install till I can locate the 5531-A's speedometer gears. Taken a couple of other Spicer main transmissions and a Watson auxiliary down but the drive gear ID wasn't small enough. I have a few other options for tracking the miles but none as simple and dependable as a couple of steel gears meshed together twisting a cable.

So pretty much like any good project, moving along as time allows. Glad to see it coming together!
