Does anyone remember Orteguil underpinners?

[lawrieh]

I am being offered a Orteguil GP-85 mount cutter. It had seized slightly after a year or two in storage but have managed to free most of it. It has no stops for moving the carriage forward and back but I think I can fix this.

It had a dozen or so V nails with it that I used up testing it, unfortunately nails from my alpha don't fit, does anyone know if universal wedges will fit?

It has 10mm nails at the moment, I normally use 15mm. does anyone know if other size nails can be used.

Also does anyone have a manual they could send or post dome photos of?

Any help would be appreciated.

Anyone with any knowledge at all of this underpinner? its surprising just how little information there is of it on the interest.

I would try asking some of the well established suppliers like Peter at Framers Equipment Northampton or Lion's or Mark at underpinnerspares.co.uk.

I take it you've seen this page on The Grumble?

The orteguil manual isn't quite the same model but might be helpful.

Yes, thanks. I've seen the page. I guessed the GP81(in the manual archive) and GP85 (mine) are fairly similar but there are obviously quite a few major changes.

There is no key for the parts diagram which doesn't help. I had noticed that the manual does imply different size v-nails but i assume alternative sizes are as rare as hens teeth.
