Loctite wheel to shaft

[Bob Brown 1Participant @bobbrown1]

I use acetone for degreasing, pure acetone, not the stuff your wife may use for her nails.

Works for me!

Hi Neil

Go to your local car paint suppliers and buy celli gun wash about £5 for 5lts will clean any grease and dust and dry out.

Neil, that's an interesting question. I think I have seen the solution in one of Dan Gelbart's Youtube videos. There should be 18 parts, but on the selection on the right I don't see all. Someone knows how to find all vids of a certain contributor? (end of OT interrupt). So I can't locate it at the moment.

Well what stayed in my memory is the following: whatever solvent you use, after it has dried off you still have a one atom (molecule) thick layer of organic matter on your material.This can be proofed by trying to net it; the water will build 'balls' and flow off. The only way to get rid of that is to treat the parts with a flame from your trusty propane burner. Maybe to around 150-200 deg.C, I'm not sure about that, but after this treatment the water will adhere to the surface and wet it. A surface like this will also be netted by your epoxy/acrylate or whatever adhesive you use!

If someone is able to find this video I would very much like to hear about it again.

Part one is here: Gelbart

OK, addition to my poat above: I found it! The trick was to search for tha author's name.

It is in part 6, Coatings

He shows 3 methods best is sandblasting, second the heating (bluing he says, so a bit hotter than what I wrote), and the third cleaning with some abrasive kitchen cleaner.

Have a look at these vids, this man knows a lot and even I am able to understand his English very well (something that's not always the case, unfortunately…)

Regards, HansR.

the cotton reel method is very useful for locomotive wheelsets when setting up the second wheel on the wheelset in a quartering jig. the smaller the clearance for high strength loctite the quicker the glue becomes solid and grips tight! (i found this out the hard way when i first used loctite on wheelsets many years ago using a tight sliding fit and the first wheelset had the second wheel solidly glued before it was fully on the axle! i would guess this was after less than 10 seconds setting up the jig!)

cheers,

Don't use nail polish remover, it usually contains an oil additive.

what is the cotton reel method?

[JasonBModerator @jasonb]

Machine the central section of the axle spigot a thou or two smaller. Apply loctite to the spigot then when you press it into place the two full dia ends locate the wheel but the recess allows a space for the loctite. Also les sfriction so you can rotate wheel to right place

Many years ago, too long to remember , I did a simple test on loctite retainer, two-part epoxy and soft solder. Used 3/8" bolts(plain shank) in 3/8" holes drilled in 1/2" black bar. Tested with a torque wrench, soft solder by far the best, followed by the 2 part epoxy. I must emphasise that this was not a proper scientific test! Sorry can not remember any figures. If I can find time I would like to repeat it, with a bit more control.

[Enough!Participant @enough]

You need to optimise the bond-line thickness for the epoxy and loctite cases or the results are meaningless.
