Hi,

I'm a furniture maker by trade but occasionally make picture frames. Normally I strengthen the mitres using veneer keys.

Yesterday I picked up this old underpinner for £35. Thought it was a good buy for occasional use. Everything seems to work as it should. The guide/head looks like it accepts 10mm wide v nails.
Are all v nails universal and does anyone know the make or model of the underpinner.

Thanks, Eddie

That's a Euro 'Butterfly' model. I stated off with the basic (8001?) model which I used for 30+ years. They do have their quirks
though.... The pressure pad is a bit inadequate and can dent soft wood. I made a cork-faced triangle of ply to place between
the corner and pad.

I started with one too. Euro moildings went bust years ago, their HQ was a few miles from me in Worthing

If you ever see a Morso that colour, it's one of theirs, they had the manufacturer spray them to match their underpinners!

I used these V nails, it won't take over 15mm and I never tried smalller than 7mm. Like most non-pneumatic underpinners, it's not that good with oak and ash.

That's brilliant thank you.

"it won't take over 15mm" should have read 10mm

Thanks for that. Been in in touch with lion picture framing and they've sending me out some v-nail samples.

Explains my very rare blue Morso!
