Shouldn't be too much work. I drill 8 holes on each pine tread. Place the new oak tread on it. Mark through the holes to get the exact position of the thread inserts. I plan on using those thin sheet rubber bands, the ones they use in the gym, as a film between the pine and oak treads to deal with any wood on wood movement if there is. I have already dealt with the pine stairs creeks years back and the issue never returned. My only concern with this, isn't the work, but the strength of the inserts as a unit.The double bolts should deal with loosening over time and I'll probably use some threadlock on the outer bolt

I have a viesmann 222f. Best boiler I have ever owned.

Hi I have an old pine staircase. I have bought and spent several weeks fitting new solid oak treads. I want to be able to do maintenence on these including replace if needed. I don't want nails or adhesive. I have full access to the underside of the pine stairs. What I want to do is install 8 stainless steel thread inserts into each underside oak tread. I will then use washers and double bolts from the underside of the pine treads to fasten them. I will probably also use a strong adhesive or epoxy on each thread insert to enhance the join. What are your thoughts on this as a method to join the oak clads to the pine stairs with options for future maintenance and replacement without needing to deal with nails and adhesive?
