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
@AndysMachines2 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.

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.
@AndysMachines2 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.
@rjserra55352 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.

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.

@AndysMachinesАй 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)

Hi Ron, The .asm file is the assembler file that the .hex file is compiled from. You don't actually need it, but I included it as some people might like it for reference, or to edit it if anybody wants to modify the code. 2. It sounds like avrdude can't find it's configuration file (avrdude.conf), either because it doesn't exist, or maybe because it's not been told it's name? Have you just installed the arduino software? If so you might need to use the IDE itself to upload a file to the board (eg. with 'hello world' or any example project). This might initialise the configuration, but I'm really not an expert on arduinos, maybe somebody else reading this might know the answer? Yes, you will need to set the -PCOM command to suit if you are not using COM 6, I neglected to mention this in the video, but I have since updated the 'how to' text file.

It's a Sandvik (17:01) but any decent bi-metal type should do it. Keep the speed low, use cutting oil and clear the chips frequently. You can also drill a small hole all the way through in the path of the hole saw and this will let the chips fall through, though I tend not to do this as I find the slug removed by the hole saw very useful (this one actually became a gear for another project!).

Is a gear cutter for cutting a rack the same tooth shape as the hob? It seems like perhaps with multiple passes, a rack cutter could cut any number of teeth by turning the gear a bit and moving the cutter the same amount to simulate what the hob is doing.
@AndysMachines Жыл бұрын
Yes, a no.1 gear cutter (135 teeth - rack) has the same tooth profile as a hob, though obviously the teeth are not arranged in a helix, and can be used to cut any number of gear teeth by rotating the blank and moving the cutter along the tangent an equal amount (measured at the pitch circle diameter). Using this method you can even cut less than 12 teeth which you can't do even with a number 8 cutter in a normal set. If fact you don't even need a gear cutter to do this, it can be done with a regular tool like an endmill or (better) slitting saw. I have another video explaining this method: kzfaq.info/get/bejne/m6ldgsalr9W7pmg.html
