I might have to try it with and without on some scrap.

I think I picked up the epoxy pore fill regime from recommendations for use with TruOil, which I figured was similar enough.
I would be interested to hear how you go

Re: Help with OSMO PolyX

Following this one with interest. I bought a tin of PolyX satin to use on my current build, and I was planning to do a Botecote epoxy pore fill underneath. Hi Tom - I have been keeping an eye out for feedback from users of Osmo over the past couple of years. This thread on a UK forum includes advic...

Re: Help with OSMO PolyX

I am pretty happy with how my previous Osmo finished instruments have survived, and am looking at similarly finishing a GS Mini sized guitar in English Walnut and engelmann spruce, with a silky oak neck and yarran fretboard. I have a couple of queries I’m hoping to get views on, particularly from an...

Re: Flat top mandolin in Engelmann Spruce and Otway Blackwood

Thanks Mark. I'm pretty happy with the Osmo - there is a bit more technique to the application than I first thought, but after a couple of builds I'm starting to get the result I wanted. The soundboards are a bit less forgiving than the hardwoods, and I find getting an even result more challenging. ...

I have just completed a flat top mandolin in Engelmann Spruce and Otway Blackwood. It has a mahogany neck and Macassar ebony fingerboard, with a mortise and tenon attachment joint.

Re: Sealing bindings/ purflings before pore filling alternates

Let us know how you go.

What are you using for pore fill? I've finished with PolyX a few times, and have not pore filled because I was unsure about how best to pore fill under an oil based finish. Even without pore filling, I've been pretty happy with the PolyX.

Hi Bob, I was always a bit concerned about disclosing this method many years ago as it was not the done thing, but then I saw Taylor Guitars was doing it so I felt better then.

I'll have to show my dedicated drilling machine for doing the neck holes.
Cheers Taff
I'd be interested in seeing them!

Re: Mandolin in Engelmann Spruce and RIver Oak (redux)

I use bridges made by Vern Brekke. Mandolin, mandola and Octave mandolin, carved top or flat top. They are adjustable but don't use thumb wheels and are adjustable via two allen screws that move two wedges in or out. Very neat design, and Vern can make them to your specifications in terms of bridge...

They both look lovely Bob. What are your thoughts about the two different bridge styles that you have used on them? One adjustable with thumb wheels. The other fixed height and looks lighter. I am quite a novice in mandolin style instruments and don't know the pros and cons of each type. Thanks Mar...
