Started my channel with a big restoration project. I have managed to remake two bushings out of eight. Thought i should get a new milling machine to help with the project, this turned out to be faulty due to swarf in the spindle bearings so had to fix that. Then i stripped it down because i didn't trust i could use it without checking every thing on it. Found that one of the way looked like it had been scraped in with an angle grinder so i quickly learnt how to scrape ways in (sort of). Now two new work projects have wormed their way in. started one and found that my new vice is wonky and will need sorting. Wish i had time to film it all (:
I think a lot of us can relate to starting projects with great enthusiasm, my father passed away in 2012, and we’re still going through his stuff. Most of it is half finished, but we hate the idea of getting rid of it. I’d be as bad as he was, but live in a one bedroom apartment, and already had to get rid of my stuff. Do what interests you and don’t worry about the rest. Take care.
Hi Jeremiah, thanks for watching. That straight edge is not a full triangle. The thick side doesn't have a sharp corner. It it sort of flat pentagon. I think it was a shop made tool, milled from a slab of meehanite.
I made a small prism out of round bar and used that and a DTI to measure the parallelism to the flt way. I think that is in episode 3. Thanks for watching.
Any recommendations for sourcing a large, triangular straight edge? I can mill and scrape a rough casting, but have not been able to find anything for less than what my mini lathe cost. At this point, I think just chopping and scraping in some cheap 123 blocks may be the most cost effective way to do it.
Hi Ethan, that will depend where you live. In the states, I would guess that a granite straight edge from Shars is probably about as cheap as possible. [Edit] Hold that. I see that the 12x18 granite surface plate I bought from Shars in 2007 for $18, they now sell for $157. What happened there? The cheapest source of good quality, well seasoned cast iron is the local scrap yard. The perverse thing is that the cheapest way to get a billet is to buy a worn out old machine tool, like a lathe, and cut out a section of a way to make a straight edge. I got lucky to pick up that staight edge at an industrial surplus place a couple of hours east of Bratislava, in Slovakia. Then again, for the gas, and all the other junk I bought in my shopping frenzy, I probably could have bought something off Ebay. 123 blocks wont replace a straight edge, and surface plate.
This Old Tony sent me! I've queued up you entire 39 episodes of the Mini Lathe! So far, so good! Thanks for the content!
Looks like you have a busy binge watching session ahead of you. Enjoy.
Ditto
@@seanchinery Welcome.
@@RotarySMP I am enjoying very much! Curious in what part of our wonderful world are you?
@@Watchyn_Yarwood A Kiwi un Austria. Thanks fro watching.
This is not polishing a turd, this is polishing a turd to a mirror finish. (but I like it) :D
Thanks. Yeah it was a little excessive. Good practice before I got the Schaublin :)
Great vid, I learnt many things from there. Thank you.
Thanks for watching.

Getting started in machining is frustrating, as you need a lot of tooling to do the stuff needed to make tooling. I wonder if that ever stops.
Great video, great teacher. Thanks for sharing..!
Thank you for the encouraging feedback.
Those angeled ways are sure flat now, but are they parallel to flat ways and parallel to eachother? Not even one measurment for this.
Just learning to scrape. Not good at it.

Great life philosphy. Thanks.
You could flip the straight edge around so that the heavier side is toward the work.

Nice, how did you enscure that all face are in the right angle to each other?
With the bed ways, it is not really relevant whether they are at 90° It is important that they are parallel.
Hey, nice work! How did you make sure the prismatic way is level/in line with the flat way?
I made a small prism out of round bar and used that and a DTI to measure the parallelism to the flt way. I think that is in episode 3. Thanks for watching.
The public commitment to finishing projects is EXACTLY why we started PedalBox. And we've sort of kept it up, even if we still have 5 on the go...
It is a good motivator. Thanks for watching.
What project is an engineers favorite? The next project......
Good call.
Of course I'm gonna subscribe
Keep up ur good job
Thanks

Where would one get a real straight edge in say Austria? Or is it better to scrape from granite?
Probably best to keep watching Ebay.Kleinanzeigen for "Tuschierlineal"
You cant scrape granite. It is ground and lapped.
@@RotarySMP I meant more to scrape one with a reference granite plate. Do wonder if a polished tombstone would also come near that flatness 😄
Whose channel was it with the big lathe restoration?
ua-cam.com/users/lookcreations
Yeah I hear the huge number of half finished projects.
The UA-cam channel has helped my start fewer projects, and concentrate on finishing some.
