Wonder If it could be easy as drilling through the side to the sleeve with 5/16 bit and plug welding the hole... thoughts? or drill on an angle under the sleeve and plug weld... thinking of a way to pin them without drilling through them.

 

Maybe I'm not understanding but you would either have an aluminum plug in the steel sleeve or drill into the aluminum block and have a steel plug protruding into that?

 

I'm going with a steel "plug" (basically slag built up from the OD of the sleeve?) protruding through the exterior of the block. Interesting idea...

 

No way the melting point of alm is 1800' I think steel is like 2700' ish you would have a molton mess of alm way before any thing would stick good to the steel ! Just sain blamo.

 

no need to reinvent the wheel others have done this.

spot weld?

 

I'm thinking even if somehow you managed not to melt a giant hole int he aluminum the problem would be that the "fit" of the slag plug would not be exact and have some gaps which could still allow movement since you aren't really fusing the two metals together.

 

How thick are the sleeves? Could you simply drill a hole 1/3 - 1/2 of the way into the sleeve, then thread the Alum and place a Set Screw into the sleeve? Maybe even a couple of them?
