  1. Viola d'Amore check in, please?

    they're certainly high and dry now :-) cheers edi
  2. Viola d'Amore check in, please?

    Good - now put on the kettle and make a nice cup of tea. Cheers edi
  3. Advice on how to cut tree trunk into slabs

    Hi Grffynda - last night I stumbled over this... - and bookmarked it as something potentially useful. Now to make me a froe and find me some billets :-) cheers edi PS - I have just watched the video again and realized that the little wedges that he makes when thinning the shingle would make ribs that would exactly match the pattern in the plate.
  4. Advice on how to cut tree trunk into slabs

    - a beautiful solution. cheers edi

    ... did you note the pitch of the fork? cheers edi
  6. Viola d'Amore check in, please?

    My ex-climbing partner has just reported in from St Pete's that all is well. Far less exciting than promised/forecast. cheers edi

    - or maybe shod with violas and surfing the surge... the mind boggles. Having experienced 2 - 3 momentary unintended flights in a mountain blizzard my thoughts are with everyone under weather threat - cheers edi
  8. bubbly varnish inside my ribs

    Hi Keyboardclass - sorry I wasn't clear. A pic of the varnish-side of that rib. First thoughts lead one to suggest a very porous piece of maple. Years back I was oil-finishing a new rifle stock. There was a soft area on the opposite side from the cheek-piece that literally sucked in the oil finish like a drought. It took almost 30 months of work before it began matching the remainder of the stock . It's not as frightening as it sounds - I was shown how to do the job by a "stockman" who served his apprenticeship at Holland & Holland. Application was much like doing a violin. A drop of oil on a glass plate, spread it out thin, pick up a "fingerprint" of finish on a finger-pad and rub on that miniscule bit of finish over an area of about 20 x 20mm - overlapping the previous square. It's like the tiles on a roof. The final bit was to friction rub the stock with the palm of your hand until it was almost too hot to touch. He loved to say about applying an oil finish "Once a week for a month, once a month for a year and once a year forever." He had a point cheers edi
  9. bubbly varnish inside my ribs

    Hi Keyboardclass - could you describe the varnish - thickness, hardness etc? Maybe a pic of the other side of that rib. cheers edi
  10. Interesting old French cello

    Hi Jacob - I've never seen what the grain of a rubber wood tree looks like - anyone? A subtle way of controlling that wolf-note warble? cheers edi
  11. Perry Sultana...

    Hi lpr5148 - what frequency is that? 11 11cps perhaps? Lovely wood too. cheers edi
  12. Specific Gravity, Density

    Ha Jim - being so familiar with those measurements indicates a very well rounded youth. In the 80s we played around with how to extract energy from the Agulhas current - the flow rate was a mere 70 Sverdrups. Half that of the Gulf Stream but closer to the cast and shallower - easier to access. cheers edi

  14. Specific Gravity, Density

    Hi All - my uncle, Eduard (I carry his name, but the Anglicised version Edward.The diminutive in Croatian is Edica - hence signing off as Edi! - just thought you might like to know) arrived in South Africa in 1951- carrying a degree in Structural Engineering from the University of Prague. He then had to shed all his metric units and learn the Imperial System with its inches, feet, pounds, gallons etc. I grew up and found myself following the family tradition into the building game. (For those who have seen the film Battle of Neretva, my uncle was part of the engineering group that designed and built the structure that connected the opposite bank to the fallen bridge. Yup - they actually took time to run calcs. They reasoned that they had to get it right the first time. Usual engineering constraints, tight time schedule, no provision for cost over-runs, shortage of skilled labour and huge and looming penalty actions threatening for late delivery! Curiously he didn't want to see the film - "Why should I? I was there!") Anyway, his opinion of the archaic and illogical Imperial System is best left unrecorded (I don't want to offend any delicate sensibilities on this forum) Inches, feet, yards, ounces, pounds a ton of 2240 lbs ..... not a single bit of uniformity amongst the lot..... Comes the mid 1960s and the country goes Metric. This 3 year old mechanical engineer braced himself for a gale-sized sigh of relief and a continuous psalm about the superiority of the metric system from his Uncle Edo (the Croatian abbreviation of Eduard). Not a squeak, not a murmur, quiet as a tomb..... I wait - I'm almost disappointed...I begin to get worried.... I furtively approach the subject as much subtlety as I can muster. . (Croatians don't do subtle well - the bigger the problem - the bigger the hammer. I consider my hammers to be precision instruments). Finally he brings himself to talk. He flatly refused to return to the metric system. For all its illogicality, he said, once you have mastered the Imperial System it is almost impossible to make an error - especially a decimal point error. The very units prevent it. A pound - open the fridge and pull out the butter and there, in your hand, is a pound. Easily assimilated and felt! Telling yourself that it is 454 grams is meaningless. An inch is a real life thing - just look at your thumb, A foot - self explanatory, stepping a distance off in yards is easier than stepping it off in metres.... I was standing next to him when he signed off his last drawing at a young age of 83. OK - the dimensions were metric but his calc. sheets were still Imperial. To match him I have to keep at it for another 5 years. Can't let the side down. Hey - his engineering career was delayed by the war. Let's see 1997 - 1951 = 46 years My career? 2017 - 1962 = 55 years. Maybe it's time to retire - just maybe. Although there are three dams to build on the farm, a 300 sq.m. cloud catcher to erect at the top of the farm, a maintenance and packing shed to erect, maybe a mono-rack system for moving stuff up and down rocky terraces. There's still too much to do. The view across the valley - 10 days ago a bearded Protea at 4000' AMSL. cheers edi
