Grub screws

Hi All, looking for an easy way to install a Lovejoy coupling on to a shaft with minimal tools , I am thinking of drilling a small hole into the shaft so that when I install a Grub screw into the coupling it would have a better grip.
Any thoughts?

Re: Pneumatic cylinder

Pneumatic cylinder

Hi All, still having issues with the gate arms, can anyone help with figuring out what the best size cylinder would be, things have changed over the years and we are thinking that the cylinder may not be large enough, any formulas we find are confusing.
Thanks

Diesel whistle

Hi All, we are looking to install a diesel whistle on a ride around gas powered 7.5 gauge locomotive, something that is not too over powering, right now we are using a set of car horns which doesn’t quite make it.
Any thoughts?
Thanks

Re: Crossing gates

Hi All, let’s see if this link worked so you can see how these gates work, it maybe a balance issue, we really don’t want to shorten the gate arms.
Looking for suggestions
