You should consider adding trepanning to your skill set. The next time you want to cut a round round out of rectangular piece of material it is a lot faster, easier, and leaves a much better surface finish that is concentric to the rest of the part. If you are concerned about the inner part falling out at the end consider leaving a thin web at the end of the cut.
@AndysMachines3 жыл бұрын
Yes, I sometimes trepan thin material on the lathe, but these plates are 20mm thick (~3/4") which would need a very long thin trepanning tool. I suppose I could cut from both sides though. Any time I want to remove a lot of material quickly my first thought is usually some method of sawing it off.
@rjserra55353 жыл бұрын
@@AndysMachines Hi Andy, Thanks for the reply. However, thickness of material does not limit trepanning. It is a great way to remove material. You clearly have the ability to grind trepanning tools. It is a lot like grinding a boring tool that creates shank clearance on both sides of the cut (similar to a hole saw creates a curf wide enough to allow the body of the saw to follow the teeth down the hole). It is not difficult if you understand the geometry and the clearances necessary to manage your chips without hitting the stock on the inside or outside during the cut. I encourage you to look into it. Regarding your comment on sawing off the material, the way you did it in the video created a situation where you had to deal with an interrupted cut on the lathe when you cleaned up the OD of the part. Interrupted cuts are always time consuming and can damage your cutter if you take too deep of a cut or use too high of a rotational speed. If you insist on using your band saw to cut off the square edges of a "round" part then you should consider going to a more narrow blade on your band saw. With a narrow blade you can scroll around the inner part and minimize the stock left for later removal. Once you get used to this you will minimize (or possibly eliminate) the interrupted cut and material removal. Hope you are not offended by my comments but I am just trying to help you. I have over 50 years of prototyping experience and figuring out how to make things. It is hard to go away from old habits (especially in matters of things you have figured out for yourself). However, the faster you get at doing things the more magical things you will create. Any you are a very creative guy. I have a couple of other simple suggestions for you but this is getting petty long so I will make another comment after a while. Cheers, R J
@AndysMachines2 жыл бұрын
@@rjserra5535 Not offended at all! Thanks for taking the time to write such a long comment and share your knowledge. I have ground trepanning tools in the past by hand from HSS blanks, I usually made them fairly short as that's all I needed and I found making longer ones more time consuming and the tool itself becomes more fragile with length. I don't actually have a bandsaw now (have owned several in the past), so I often go for the quick and dirty 'lop off the corners with a hacksaw and true it up on the lathe.' An irregularly shaped blank does take longer, but I generally use HSS tooling on the lathe so the interrupted cut is not really a problem. Happy to hear any other suggestions!

get yourself a mister. Use the expensive synthetic stuff and use it very sparingly with high air flow about 35 - 40 PSI. It'll improve finishes enormously because it'll blow chips away keeping you from recutting them. It'll also extend tool life and allow you to increase speeds and feeds markedly. For that T slot I'd use a flood. I was concerned about a mister in a small shop. But the synthetic stuff is non toxic and I use so little.

Very nice. Thank you. I usually just skip to the end on Build videos to see the final product, but your editing of the video was so well done that I watched every minute. Question: Instead of cutting the corners off the flat stock with a hacksaw at 5:00, and then later spending a great deal of time removing the rest of the stock in the lathe at 8:50, why not use the rotary table and a small roughing end mill to do the job? I find this work well. Thanks again. Looking forward to part 2
@AndysMachines3 жыл бұрын
I'm glad you liked the video! Yes, the rotary table is just as good a way of doing this, though personally I only tend to do that when I don't want a full circle (such as when I rounded off the corners of the frame). I roughly knocked the corners off first just so I could centre the part in the 3-jaw on my rotary table (with shims and moving the chuck on the table) to cut the T-slots. I left the final finishing of the faceplate until everything else was welded, bored etc. in case there was any movement.

Next time you hole saw a hole... scratch the surface with the hole saw, then drill a hole tangent to the scratch mark. This hole allows chips to fall out of the cut and prevents chip packing in your hole saw gullets. You'll cut faster and with less heat giving you years more with your expensive, carbide tipped hole saws

@AndysMachines2 ай бұрын
I think I did get this question from somebody who had a mill with a head that didn't tilt. You can't just tilt the work spindle an additional angle to compensate, since the feed direction must be parallel to the teeth. If you used a large diameter hob with very small teeth and hence a very small helical angle then you could probably get away with not tilting the head (the clearance angle ground on the teeth would be greater than the error, so the teeth would still cut without rubbing)

Thanks Keith for the comment, I didn't actually produce drawings for the attachment as none of the dimensions are critical. You can alter the design to better suit your own needs or make use of whatever materials you have to hand. If you only want to cut spur gears (rather than helicals) then the attachment doesn't need to tilt and can be much simper. All you really need is a shaft rotating between two fixed bearings that you can attach a pulley and stepper motor to.

You do some really nice work. I’m really impressed. But I’m surprised that you don’t seem to use any machine coolant or even thread cutting compound such as Trefolex. We always used both.

You can imagine the jokes that went along with this rule.

I DO use cutting oil, even flood coolant, but I generally don't show the application of it (though you can see it's there) and I don't use flood coolant in the videos as it would obscure what's going on. Maybe I don't use as much cutting oil as some machinists or reapply it as frequently, and I don't use it for everything, but yes, always when tapping steel.
