Nice job! Suggestion on the labels if you have to do something like this again: you can get a package of 8.5x11" sheets of labels in various sizes, such as the size you were using. Get them at Office Depot or wherever for a few bucks. You can download a template for Word from the label maker's web site. Then you can just copy/paste the boiler plate to a bunch of the labels in the template, and even serial number them if you want. Print the sheet in a laser printer, and you are done. Peel and stick.
Brad could I make one very small suggestion. If you are going to deburr a part close to the chuck with a file like that don't hold the butt of the handle against your hand. If you hit the tip on one of the chuck jaws it will jam the handle into your hand. Hold the file in your finger tips such that if something hits the file it throws it clear of your hand. Of course a proper handle would even be better. Great video by the way.
Well we are always the viewer at the end of the train on RU-vid running about 1 to 2 years behind everyone else, Brad I see some really nice fellow RU-vidrs listed here, we watch them as well, the spacers look nice in Teflon but we love your little packaging process as we love all things small machined even the plastic baggies and micro labels.
Back before dinosaurs ruled the earth, I watched a machinist single point thread teflon rod. The material was much softer, slicker, and less rigid than the material you are using, so there were some challenges to the procedure. He mounted the rod in a bench lathe and sprayed liquid nitrogen on it, to make it more solid and more rigid. Then the threads were easily cut.
If you have a bunch more of these to do I think using 1/8" sheet and building a punch would let you produce them with less waste and in a faster time. Just a suggestion though as you did just fine. :-)
I'm curious what the edges of the part would look like. I dislike working with punched metal parts, the shear distortion and raggedy edges are just so wrong to me.
If you had a turned sacrificial wood rod with a bore in it to catch after parting, that fit snug inside the bore of the teflon , you could probably part off without having any burrs or fad left on the teflon. Teflon - dares to be chattered! Glad you got lots of work in the new business.
Just curious, are you ever going to put out the remaining video's on the South Bend Shaper Restoration? I really like that series and was looking forward to the remaining videos.
Enjoyed...just a random thought, the labels would be cool if eash one had the shop name on them....advertising as you never who will touch the part after it leaves your shop....enough labels with your shop name and it becomes a no brainier when someone ( the boss) says who can build this and the end user says Maple Lane😃.....IMO, RU-vid is fun but your business and family is more important than viewer videos...only so many hours in a day
Well said Chuck. Great idea for the labels too, but those labels are actually another "spec" to the job. Only drawing number, date & sequence are permitted. I agree with all the other comments about having it automated with Avery software, though - totally.
I have enough youtube machining channel subscriptions now that I basically have to watch a 2x speed in order to get through them all. That might have effected how I felt about the music. LOL! Still great content- keep it up! Thanks!
Can I ask why you didn't grind an angle on the leading edge of the parting tool so that the washer would be parted of clean and then carry on with the tool to face off the bar.
Because it's a carbide insert and it was just there. I'll define;y be making an adjustment to the parting process (because these might be a re-order part), but I wanted to knock the job out really quick. But yeah, you're right.
I made Teflon washers before, can you guess what kind of a parting tool I used? They were smaller, think was around 3/8" OD. The tolerances were real small probably because these go into microwave communications connectors. The order was for 300 pcs. What was the quick and accurate cut off method I used, a razor blade.
How was the finish? Did using a 'displacement' tool instead of a material removal tool with a kerf, affect part dimensions? How were the burrs (if any)?
I had to break the edges on the hole. The outside edges were sharp, but ok that way. The dimensions held, had no issues maintaining them. Being that they were only 3/8" od, that made it easy to hold size. It would be interesting to know how larger sizes would hold. Additional info, I made some larger Rubber Washers using this method, those had a somewhat rough finish. The dimensions were not critical, and so, I had no issues making them.
hey bro im new to your channel.....i have a heavy 10 with the original papers ....ive been doing maching for 22 years ....i have bit , steady rest , collet closer ...tooling.....a few insert tools....3 jaw ....set of collets .......quick change.......i have a oil chart to go with it .....history......looking for 5k....i can send pics ....i framed the oil chart.....need pix let me know ...im in ct
