Interesting. I take it that these collets don’t make use of a draw bar? I’m just trying to figure out what type of collet you have here. Maybe a picture.

If these are MT3 collets they can be as good or better that ER32 collets for Work holding. One point that would be an advantage is not needing to screw on / bolt on a collet adapter.

Actually in many cases you can do better than purchased. At least you can on a limited budget. A classic example are tap and die holders. These can be made dirt cheap out of scrap steel and even if you go the tool steel route you will still save money. Tool building is in fact a great way...

Have you considered shipping the tools to Australia? Air freight might be a decent choice here. Decent in the sense of being competitive with buying the equivalent new machines. Stuffing a air freight container with everything you can find would also help with costs. Personally I’d...

The copyright system is easy to understand so I’m not sure why people have so much trouble doing the right thing. It is up to the author to decide if he wants to profit from his efforts. If so a book gets printed or the work gets distributed in another manner as a copyrighted work. If the...

Actually there is significant evidence that these misting systems are bad for you in general. You end up with air heavily polluted with the mist leading towards all sorts of health problems.

There is not much I can add to this thread other than I spent some time with a guy from Germany that bent some really complex hydraulic tubing with the dry sand trick. If I remember correctly the tubing was 50 mm diameter with a heavy wall. Heat was from a large Rosebud torch. Being young at...

Well Linux itself isn’t hard to learn. Admittedly LinuxCNC is a bit more involved and thus has a longer learning curve. It is however better supported than Mach 3 these days. Given that you want to run Mach there are ways to get possible solutions, here are some suggestions: If you have...

I must admit that it has been a long time since I scraped anything for a living but my memory is still pretty clear. When you have a finely scrapped surface and a decent reference surface your spotting action will show up the highest spots as a shinny surface generally surrounded by a border...

That is a lathe stand from the good ole days. You are not likely to find such a cast iron stand new these days.

Slick use of a small lathe. I'm wondering what you are using for CNC control?

You could always drive across the border, find a Canadian post office, and mail from there. In any event something does sound odd with the pricing you have.

In a situation like this I’d make the seller come up with a price. As such the price should reflect his needs and the value in the machine. If it is excessive compared to used prices you can then decide if you want to negotiate. In a nut shell it is better to start with a selling price the...

Honestly I wouldn't bother with a new scroll chuck unless you can find one with two piece jaws. You can probably find such in a 5” class chuck but commercial chucks are heavy for that size of lathe. In a nut shell scroll chucks are not that accurate and the cheap ones wear rather fast. Your...

Proof that you can learn something new everyday. For one I would not have even thought of using a paint brush to aid in soldering or tinning large pieces. This also makes me wonder if the silicon brush can do as an acid brush.

In the past I never had an issue with Dykem Hi Spot but that doesn’t mean quality control went out the Window. Part of the trick with spotting is, as guys pointed out above, is to apply the spotting material in very thin layers, the material should almost be transparent on your reference...

Never heard of them. It looks like you have exposed threads on the spindle as such it strikes me as a cheap rendition of a Micrometer.

Welcome aboard! I’m not sure what has frustrated you here but don’t be afraid to ask questions. There are guys with decades of experience here (not me) that can provide great insight with respect to model making. By the way references to books and magazine articles is a good thing in my book...

I think I watched the same video last night. I’m surprised that the bit didn’t shatter in that case. In any event I really believe that home shop machinery should be fastened down in some manner. The last thing you want is a fast sounding spindle rolling about where you are working...

I’ve picked up more than a few old stones at auctions. Some of them could use this treatment. On the other hand s concave/convex surface is good for gouges and other curved tools.
