    All the inserts I ground for the class I did 90 and 60 radius..

    RC is correct it was 90 to rough in, 60 for the rest. the radius gauge also had a 40 for fine work but this wasn't used at the work shop.

    Wonderful work gents. You guys didn't get a go on a Biax by any chance? I bought a used one thinking I might use it one day and after the scraping course I attended here in Norway. After having a go with it on our scraping course, I am in love with the thing. Roughing is so much quicker although I would still bump scrape to get the final 40 PPI.

    I have a 600 X 400 cast surface plate I need to scrape in. I am actually looking forward to it. It's a sickness

    Paul.

    We had 4 of them here, although we only dragged two out. That part is one on one instruction. Power scraping and a HM 10 mottler. There was 2 of them here. Power machines are a second day activity, once they have the basic's down.

    The boys also got to use a Renz. http://www.renz-eiro.de/

    R.K would poo-poo those, but he has ties with Dapra.

    Regards Phil.

    Great weekend and I learned a lot. All very enjoyable, top company and top food.
    Many thanks to Phil and Marko and the support crew.

    Phil - I don't think R.K would rag on the Renz as he seems to be pretty pragmatic about the power scrapers. It seems like Darpa / Biax are backed by Metabo as the electrics are from Metabo, while the Renz appears to have electrics from Fein.

    I like the look of the Renz however I have never seen one in the flesh. I have stumbled across a few Biax scrapers here in Scandinavia and they occasionally come up at a good price. I bought mine from a friend for $350 with a few cabide blades and a couple of long blade holders. It was a little rough when I bought it but ended up giving it a clean, service and repaint. Internally it had very little wear so I got a decent deal. It has no speed adjustment so I run it through a Variac.

    I could clearly see that we are spoiled here as we had 6 student owned power scrapers in a class of 9.

    Paul.

    I'd like to add my voice thanking Phil, Marko and all of the others who helped for what I thought was a pretty well organised weekend. The food was good and plentiful and a lot of scraping got done. Hopefully I have the tools and knowledge now to get my block nicely finished, although I will have to find where the hell I put my Prussian blue powder I bought over a year ago.

    Thinking back over the weekend, it was great to be there with like minded blokes who all got along- try telling the blokes at the local club what you are doing? Actually don't bother- they wouldn't get it! I started my apprenticeship in 1976 at AIS Port Kembla and worked on my own or with others on large machine tools Floor Borer 40 foot travel Vertical Borer around 20 foot Diameter, Cylindrical Grinders, Large and small lathes Horizontal Borers, Planers and Plano Mills were among the equipment in our shop, 50 ton jobs were not uncommon, jobs on the horizontal borer that you could lost inside of setting them up were not uncommon either! Most of this work was not all that accurate a couple of thou here or there didn't matter!We made a crankshaft for a three cylinder Galloway Steam engine once also.
    I really enjoyed what we did on the weekend scraping the block to around 1/2 a thou and square all round, with the simplest of tools and a lot of patience a lot can be achieved! Thanks again to everyone who made this possible and made it happen!

    Well put Will. I'm more of what I would call a metal dabbler than a metal worker so was not sure I would get that much out of it but Bob Thomas convinced me that I would and he was right. A bit less on the scraping side and more on the metrological side. Just talking to friends and acquaintances back here about it and they shake their heads in disbelief. I can't show them the block because I have had to post it to myself and it won't get here till next week.

    The thing is, once you have been given the basics, you can take it as far or as little as you want... But it is those basics that you learn at the scraping class that is essential..

    I know doing a fully blown rebuild is not for everyone, some will just want to flatten the sole of planes or maybe scrape in a cheaply bought cast iron angle plate, and others might want to tickle up a cross slide, just to straighten it a bit...

    The world is your oyster when it comes to what you want to do with your newly learned skillz...

    This is exactly the sort of stuff that appealed to me about this course. I am unlikely to need to use anything more than ~300 x 450 surface plate in my work, but it's knowing what to do and how to recover from endless spirals that one can seem to get into that saves a heap of time.

    I have to agree with the comments made after the scraping class. I think we all learned a lot from both Phil and Marko. Being personally shown the techniques while working on a job with either Phil or Marko watching you doing it is something you could never get from watching a video or reading a text book.
    It was also fun doing the course with a great bunch of like minded guys.

    Thanks to everyone for a great weekend!
