Bit of Netrophillia here.

I made a chamfer cutter with the Clarkson, so figured I'd link the video here.

Metal Stuff / Re: New lining for the iron furnace
« Last post by vtsteam on May 21, 2022, 10:19:49 PM »
Today after some delay I attacked the lid. Well I guess attack isn't the word -- I trashed it and started again.

New (scrap) metal welded together. new insulation blanket installed. The philosophy this time WAS to do only vertical piecing. Horizontal layers don't work, because there is no reliable way to laminate layers together. Vertical piecing means that every individula section of blanket is in contact with the top of the lid and is cemented there with a generous amount of sodium silicate.

I started out trying to do the vertical half-width slice-of-pie method, as shown in the above video, but pretty quickly that showed it wouldn't work. My furnace lid is about 17" in diameter, while the oil can in the video is about 12" Maybe you can cram the inner ends together in a 12" circle, while the outer ends expand enough to fill the spaces, but not on a wider lid.

So I ended up doing a sort of roll-up method, with strips and pieces attached concentrically, except at the center. The final 3" around the exhaust hole was done in the pie wedge method -- and it made sense there -- especially because I wanted to have a leg of each piece extend up through the hole -- similar to the way Iron Man did it in the video above.

Here is the new lid packed with insulation:

Our Shop / Re: My week this week, my workshop videos!

More clearing and sorting of the workshop stuff, and a few interesting finds. I have come up with a strategy! Next week I will finish the tractor, and then the grass cutter, and when they are done and out, I am going on a cull of all my junk, starting in the Outside store, which is full of junk, much of which can be scrapped, as the price is very good at the moment, and that will give me somewhere to move the stuff from the downstairs stores, which are impractical, as they are too far away from the workshop proper!, of course as I move the stuff, much of that will also be culled!!
Phil, the grass waits for no man in East Yorkshire!

Those should look good on it. Maybe contact them and say WTF and get all three.

My seagull figurines showed up yesterday.  When I ordered them there were 3 poses of bird in the ad, so naturally I ASSUMED I'd get one of all 3 poses.... Not so much, I got 3 copies of the same pose.  Oh well, I can work with it.  I had to try it out to see if the birds were about the right scale.

 


Whatcha think, I think it looks about right.  They're resin, so they'll be fairly easy to modify into a sitting down bird and get rid of the pilings.

Project Logs / Re: Another Steady Rest for the New Lathe
« Last post by vtsteam on May 17, 2022, 07:18:45 PM »
Had to try it out, even though I haven't even made up proper gravers -- I took an old triangular file, ground the teeth off and sharpened the end on the Antiquorn. Then heated the tip up to cherry red, plunged it in a cup of water, heated again to temper color and plunged again.

I didn't have any "good" steel in the tiny shop, but did have a piece of 3/4" hot rolled rod, and so I put that in an MT2 collet after pulling off the 4-jaw chuck. What the heck, if it cut this stuff at all I'd be happy.

I didn't bother taking off the backplate for this test. Just switched on the new lathe and started cutting. I broke the tip off my new tool a couple times. It turned out the slot was too short in the steady's base and I couldn't get close enough to close the gap tighter, so I stopped the lathe, ran down to the shed where the mill is, and gave the slot in the base another 3/8" of travel.

Back at the lathe that did the trick, and I began cutting again without the problems. And on poor turning steel, too. It took a little practice, before I "got it", but then I started to be able cut where and how I wanted!   :ddb:

I can see some things I will probably refine in both tooling and practice. But Very happy with the new capability on the home built lathe!

CNC / Re: Printer Enclosure.

I have started it printing its own parts and first off to get some of the shapes I am going to print I figured it needed a part cooling fan, so I designed a simple one that I actually think with a little modification wont be a bad for a permanent solution. My filament looks like its starting to collect too much moisture so I will have to chuck it in the dryer tomorrow.
Another plus is I am slowly learning the ins and outs of Marlin firmware, Although I may end up with a bald patch from all the head scratching  :lol:

I just finished the second Tee rest for the new steady. This one is substantial, made of 3/8" bar brazed to a 3/4" post. It's angled in toward the lathe center 10 degrees. I hope it will work well for metal turning with a graver. We'll soon find out. It may need some beveling on the top edge..... or not. Don't know yet

And a photo of the metal turning rest and wood turning rest, ready to try out.

New one looks totally different AND unlabelled.

Thanks, I think that is really impressive!

The state of play at the moment has pilot input going to a Flight Simulator program which will do all the necessary calculations (and handle the instrument display) and pass (via ConnectSim) the heading, roll and pitch values of the FS virtual aircraft.   A micro will move the cockpit etc to match those values.  Axis sensors would be needed or I could use something like this   https://learn.sparkfun.com/tutorials...okup-guide/all
