How to Add a Grabiron to the Side of the Sand Dome

Drill two holes, insert the grab with a little shaft Loctite.

or a dab of CA glue and insert into holes.

Drill 2 holes. Test fit to make sure you get both ends of the grab into place perfectly.

Thinnest of films of Goo on inserted ends.  Insert grab into both holes and remove.  Add CA to inserted ends and put into place. 

Ed,

Can you post a decent photo of the area in question?

Why do you need to access the dome interior?

Are the holes from the previous grab open or filled?

What material is the dome and grab?

Do you plan to paint the grab before or after installation?

Some type of spacer will make installation easy and accurate.

Gentlemen,

I, too, thought of drilling 2 holes to accept the grab iron but was unsure of the adhesive.  I thought of CA and a small dab of epoxy but did not think of Loctite.

MWB:  Why Goo and then CA?

Old Goat:  If I had access to the interior, I could use a dab of epoxy on the inside and it would not be seen.  The engine is all brass.  I plan to paint the area after installation.  Yes, a spacer is a good suggestion.

Thanks to all,

Ed

Something about the combination of a VERY small amount of thin CA, touched to good old Walthers GOO, makes the GOO harden INSTANTLY, and you'll never get the two items apart without breaking something. I don't know why the two adhesives chemically react that way, but it sure works good!!!

Yes, the combination of 2 is extremely potent and very difficult to separate.  It is also quite rapid.  This combination is also very useful for joining 2 dissimilar surfaces particularly if one is porous, putting the Goo on that surface.

I had a paragraph on this in one of my articles in OST - the schoolhouse structure a few months back, I think.  I would hypothesize that there is a chemical interaction co-polymerizaton between the Goo solvent (acetone) and CA that also traps the contact rubber cement within that matrix.  The combination of the 2 adhesives retains something of the flexibility of the Goo depending on the shapes and contact surface of the joint.
