|Thread: Kant Twist alternative?|
Once you have a suitable search term - Parallelzwinge, it opens up all possibilities!
Nice job Jason. I think I prefer Bernard’s design though as it looks likely to be more rigid. I only lost some of the angles on mine to make it easier to cut out.
If anyone can get the arms water or laser cut at a good price I’d be interested in a couple. Probably 2” or 3”.
Another view in case it helps others contemplating making one.
Sadly the only drawing I’ve got is a sketch in Open Office so not much good for anything other than hand layout.
Finished. I won’t be making any more unless I find I really need them and I can get the plates water jet cut!
Mostly stainless with some brass and alloy. Using hex bar for the bosses proved to be a good call.
|Thread: Grinding/making narrow grooving tools in HSS|
I don’t have any fancy grinding fixtures so the last time I wanted to shape a small HSS tool bit I did it on my mill with a carbide cutter.
|Thread: Generating a Burr|
I was careful to use the word often, as some folks still use them for bowl turning.
Indeed, I understand they were the mainstay until bowl gouges appeared about 40 years ago. If you’re interested look out for Robbo Hippy turning a bowl with just a scraper on YouTube and note the shavings!
That’s not like you Michael, apology accepted!
The burr doesn’t last long but on something like a scraper it’s often only used for finishing cuts.
Look away now if you find cutting that softer brown stuff distressing!
I sometimes use a wood turning lathe and some of the tools, particularly scrapers, cut by generating a burr on the tool when you sharpen it. It’s perhaps somewhat counter intuitive but both grindstones and belts generate this burr even though they are running downwards towards the tool. There are some sharpening options though that run in the opposite direction and I wondered if this would increase or reduce the potential to produce a burr? I could have asked this question on a wood turning forum but I suspect I may not have got any useful comments.
|Thread: How fast is fast enough|
I concur Ian. Like you I’m a model engineer removing metal for fun, not for profit. The top speed on my VMC is 2150 rpm but I’ve never run it at that speed.
|Thread: Sets of parallels|
I ended up with quite a number of pieces of ground flat stock which I simply cut to length. Using two pieces from the same bar has worked for me. I just left them soft.
|Thread: (again) buying new European made lathe|
Lots of German stuff is no longer made there. Some Mercedes are made in China.
|Thread: Shortening Screws|
Thanks for that Thor. It’s a much simpler design than others I’ve seen so I may make something similar.
What method do you use? I ask as I’ve recently seen a Lantern Chuck again. I’ve never used or much like the idea of a screw plate. I prefer using the lathe. I currently use some little plugs tapped to size and held in a collet Chuck. I just wondered what other methods folks use?
|Thread: What do you use for heat treatment?|
I’ve read that domestic ovens can be used for tempering but not tried it. Is this correct? Not sure how high my oven goes but I’m not sure it’s much above 220° - 240°C?
I’ve just used a gas torch for hardening stuff like O1.
|Thread: Lathe tool size|
These work well and have built in height adjustment.
There have been rumours about him going to work for Tesla.
Back to Volkswagen, I recently read that they are in debt to the tune of a $192 Billion. More than South Africa it said,
|Thread: Free Cutting Mild Steel Flat|
Is there a machinability index for common stainless steels? Good links by the way Thor.
|Thread: Digital Caliper - again, sorry|
My main calliper is a Mitutoyo that’s over 30 years old. I usually leave a Lidl £10 job in the workshop but the last one failed and I haven’t seen any in Lidl lately.
