I could do with a bit of advice . I am building a simple crankshaft , at the moment it is a press fit together and in perfect alignment . I understand that silver solder wont penetrate through a tight fit , but I an reluctant to ease the pin and the shaft and maybe lose the alignment , What is others experience of Loctite and pinning ?

regards

If you go to Tight running mill engine on the 06/03/2018, I had the same problem.

If the Loctite is used correctly, you really don't need to pin it as well. It is very difficult to break a joint once it has cured. It takes far more force to move, even with heating, than the shaft will ever undergo when your engine is running.

I think so, too – though presumably it depends on the forces.

I'd been thinking I'd pinned the crankshaft on the Stuart 10V I made about 20 years ago, but inspecting the crank now I can't see any sign of pinning, so I probably did just use red Loctite – and it still works well.

Anyone used Truloc 268 ( equivalent to Loctite 638 ) and have any thoughts about it, I'm about to use Truloc on my loco for wheels to axles

Pretty sure that's what I used to fit wheels on my wee loco.

Hi Mick,

I have used Truloc from ARC to make a multi-throw crankshaft, as far as I can tell it is as good as Loctite.

Thanks for the heads up on Truloc 268 guys, was looking to get equivalent to Loctite

Yes to Truloc – just as good as the Loctite equivalents.
