Morso apparently call them frame assemblers
I went into my framing supplier this morning to collect my sharpened guillotine blades, and buy a flat black stick with a 5/8'' deep rebate.
Discussed chevrons and one or two other things with Karl & mentioned in passing, that my next significant expenditure is likely to be on a Keencut Ultimat Gold. I said that I could manage with my small Charnwood overhead DIY wedge press at the moment.
Having unsuccessfully tried to sell me a £500 underpinner, he showed me a Morso Up-M hydraulic underpinner that he'd presumably traded with a part-time framer, which didn't deliver wedges properly and leaked hydraulic fluid all over the place.
He said that if I could fix it, I could have it for a peanuts price.
+ 2 boxes of wedges (8K in each)(7mm & 10mm) + some spare parts + 5ltrs hydraulic fluid + the original owners manual.
I agreed on the number of peanuts he required, and left with my sharpened blades, four sheets of decorative mountboard, my stick and a Morso Up-M underpinner. [sorry, frame assembler]
Stripped it down in the workshop - and, as suspected, found a rubber 'O' ring seal flattened in its groove on the foot pedal cylinder and particles of 'O' ring rubber floating around in the drained off hydraulic fluid.
The wedges were gummed up in the cartridge with a mixture of dust and, I suspect, glue residue.
So, a complete set of 'O' ring seals ASAP, a good clean out and careful rebuild, and I should have a virtually 'as new' underpinner.
It certainly looks as if it's hardly been used.
I've just looked on the web and they are £1165 new.
I'll try Framers Equipment first (they're local) for the 'O' rings.
If no joy there, I'll contact DanList direct.
This makes it a good start to April.
Perhaps I'll just write March off, as a bad one
