It’s really a fairly straightforward job. I assume you have the reamer and taper pins, if not I see they are available from EKP supplies. I would measure the small end of the taper pin and drill through the part with a drill that size or a few thou smaller. The reamer should enter the hole OK and, using some tapping grease or similar, hand ream some of the way through before cleaning well and trying in the pin. Don’t go to far before you try the pin in the hole as it can all happen very quickly. Slowly slowly catchee monkey. Hope this helps.

Cheers Pete

I agree with Pete, although I always open up a short distance with a slightly larger drill to give the taper reamer some relief when starting. Lots of tapping fluid, and yes, definitely go slowly. Be aware that the taper pin will go in further than you think once some force is applied to it. The photo shows a taper pin securing the lifting lever to the weighshaft on my Thomas 2. The running board had been taken off at the time the photo was taken for better access to the motion work.
