Machine tool rebuilding classes
I was looking through Gumtree online adds today and spotted this advertisement for machine reconditioning classes https://www.gumtree.com.au/s-ad/burl...ses/1252864202. It may be of interest and worth chasing up if you live reasonably close by. Unfortunately he is too far away from me even without the Covid situation we find ourselves wrapped up in. If any of you do partake let us know how you found the experience.

Shame about the location but would be great. I wonder how much the $30/hr adds up to? The Richard King course is very expensive (if it happens) but maybe they are $ comparable.

It would be a great course to do, but the location is a long way away.

G'Day Pete, long time no see (or hear). I presume from your comment that you are on the big island, but do you have your boat with you or just the ute? If you have the boat, and could commence self isolation when you depart your mainland harbour, your time would be nearly up by the time you reached home port. I trust all is well and that you are doing your annual software maintenance run.
And thanks Snaptap, you have jogged my memory, I had forgotten about Markus posting here some time ago, and was thinking that it might have been someone new to forum members here. getting old is a bugger, but as they say it sure beats the only alternative.

If it were not for travel distance I would have gone along, always keen to learn new skills, correct that Marcus was on the forum

Software upgrades, yeah. Getting close to finished. I drove up just before the situation in Victoria went to shyte.
Current rules say I can self-isolate on return which isn't a hardship for me - you've seen my place.
The boat is sitting on the mooring out the front, covered in anti-cormorant netting, waiting for my return. My friends are up here in Broken Bay on their sailboat and have offered me a crew berth to get home if all else fails.
Nothing worth adding to the collection so I may be going home with an empty truck. Shrug. Really the only thing I'm casually looking for is a surface grinder with power feeds to the table and light enough to carry in the Rodeo. I'm tired of paying the exorbitant freight across Bass Strait.
BTW I still have one or 2 of the other machined straight edge castings on the shelf if you want more practice including a baby version of the 640mm one you own. The 375mm one is an easy first project and quite useful, I used the one I scraped in to re-do my big Monarch compound slide.

If anyone ran something like that in Tassie I would be interested, Not an option for the foreseeable future though. A working week (40 hrs) at $30 per hour would be cheaper that a Richard King course. Im sure Richards courses are very good but as a novice looking to learn the basics I doubt that I wouldn't get full value of his experience.

Still here but I rarely check the forum, haven't bother getting a mobile yet and Facebook has IP banned me having a Facebook account but I'll usually answer the shop landline during the week (07) 5522 1726, The landline runs through the NBN now I think they call it voice over ip? some time back when I had ASIO rolled through my factory and brought me in for an interview after that the landline stopped working not sure if it was related but Telstra has to reset permissions what ever that means. its happens a few times since and is easily fixed but I have no way of knowing until people tell me they've been trying to call.
I listed the add at $30/hour because I've been doing a lot of one on one afternoon classes and at the normal rate of $110 per full day it literally costs me money if its just an individual. even numbers of students is ideal as I try and buddy people up so they can help each other spot parts and if I have to buddy up it often draws me away individual teaching. To add to this I've moved that colossal Beer hall table to a friends farm so its not hugely practicable to have a large class until I move it back in.
Generally once people are fairly confident they just come back at their leisure to use my plate/the Biax for their projects at no cost other than helping out at the classes, there a a few local guys who have absolutely blown me with how quickly they're picked up the art. Petar Lazarevic for instance came for a Saturday class where he was very quick to learn, he practiced a bit at home during the week and the following weekend he came and bump scraped to 40ppi to 60ppi with ease (some pics from after the second day), it was to be honest a little unnerving how quickly he picked up hand scraping and to be honest I rely so heavily on the Biax for finish scraping that it often takes me a few passes with a hand scraper to get my aim where I'm happy for demonstrations.

Gabriel (I cant even to spell his Polish last name) is another young mechanical engineer who mastered Perfect control with the Biax within literal minutes of picking it to after having watched myself and others power scraping for the morning, This is his Al-250 lathe that he scraped in, the solid tool post riser he turned after the rebuild and scraped it flat and parallel in about 30 minutes. You might ask why bother scraping a solid tool post riser but we had an interesting demonstration at one the classes, fellow from down south has a cross slide with some unusual wear and a huge solid Tool post he's milled himself (cross slide top was also dinged up) when we put it on the plate and set a indicator up tightening the cap screw bolts actually pulled a twist into the cross slide, from memory it was about 2+ thou twist but when we put the original compound base on which had a thickness less than half that of the riser it was not stiff enough to induce an error and made no noticeable difference.

I can also highly recommend Richards course, it is am amazing starting point but he often has to simplify things as its honestly impossible to fit everything into a week long course and not that I can talk but he can often get a bit political. I have spent the years since constantly learning more and more but had I not taken his class I wouldn't even be half the machinist I am now.
almost everyone that has facebook who comes here to scrape is on one massive group chat (about 70-80 guys) That chat alone has been a constant wealth of information. one of the guys in the chat organizes a group granite buy every so often which has saved us all thousands.My 1000mm x 2000mm black granite plate was about $3500 imported by Redmond gary, Josh a local hobbyiest had Dan import the same plate but thicker in a grey granite for somewhere around 2k, the smaller plates have often been at a slight premium but he had all the small plates made from insanely thick grey granite in higher end of a OO grade and as such they sit flat regardless of being on their bessy points or not. the grey granite is also far nicer for bluing up as even the novices can easily judge the film thickness of the blue vs the more common black granite. even the master square I ordered has the non working faces lapped to a point where we can only detect half a micron deviation on our best plate, something I had never even thought to worry about but the cheaper granite squares when put on their side to measure X Y alignment on a mill rock like crazy.

Marcus,
What is the name of the Facebook group?
I bought a 900x600x200 plate through Dan. Also got a master square and a straight edge.

it's a private Facebook chat not a group so one someone on the chat will have to add you, its not something you can search for. I would also highly recommend muting the chat once you're added as it goes off all the time and will get very annoying if you dont, that way you can just pop your head in to ask questions or see if someone local had the right size master for the slide you're working on. Andre who goes by "welder" on this forum is in the chat so if you have him on the facebook he can add you to the chat if not PM me the link to your facebook and I'll add you. There are also no silly questions on that chat regarding scraping so don't be afraid to ask, I don't mind doing quick videos to explain things and if needed people will often post examples from when they scraped a similar slideway and the problems they encountered/how they overcame them etc.
