Thanks for that information.

I finally found a 1/2" bolt this weekend, I was driving and suddenly saw a bolt and metal store and decided to cut across a few lanes or traffic and see what they had. 

Got it installed and now it seems the fabricator did not put a sleeve all the way across so now I'm on a search for sleeve material.  It just goes on and on!


At least sleeve material is pretty easy to come by. Even pipe from the hardware store works (plumbing section) Plenty strong and cheap!

as long as you find something close enough (but some machining might still be required) - not sure what his OD is but pipe standard for common sizes are

Size / OD / ID variations (3 or 4 different sizes)

1/4 / 0.540 / 0.410, 0.364, 0.302
3/8 / 0.675 / 0.545, 0.493, 0.423
1/2 / 0.840 / 0.674, 0.622, 0.546, 0.466

looks like 3/8 or 1/2 would be fairly close candidates

Good info.  Thanks

Will have to measure the OD but for ID the .545" looks good.

i would rather think .493 and run a 1/2 bit thru it from both sides. the 1/2'' bolt is not 1/2 inch but more like .490 or so (since i thought all this was related to the M12 vs 1/2'' which is about the same difference if you go with .545)

That's a good way to get the most snug fit.  Thanks for the idea.

The needed OD was 0.75 with ID close to 0.5 so no water pipes fit exactly (plus the 3/8 size was not to be found in several hardware stores including Home Depot).  Finally ended up getting a length of 0.75 OD, 0.52 ID seamless pipe that is supposedly used for hydraulic systems.  Weather has been cold and rainy here so might finally get it done in about a week.

Thanks for all the comments.
