Let's Build A Model Steam Engine : Spot Facing!

[@danbreyfogle8486]

Another great video. I was trained as a mechanical draftsman wayyyy back in 1967/68 (long before CAD) and drew lots of spot faces but had no idea how they were made. So now I know, thank you

[@Blondihacks]

Well, this is probably not the right way to make them, but it worked in this case. ☺️

[@cooperised]

Really enjoyed this one. I hope you never get bigger machine tools, the ingenuity you're forced to employ when working at the limits of your machines is inspiring and educational.

[@Blondihacks]

Hey everyone! Here's are today's themes in the comments. Save yourself some typing and read first: 1) Yes, using a round piece of HSS speed steel in the fly cutter would have been a lot easier. However the square piece is what I had, and it was a good excuse to practice my filing, which I wanted to do anyway. 2) Yes, you could totally do this with the boring head in the lathe. If I'd thought of that, I'd probably have done it that way. 😀 Another good way to do it would be fixturing it to a faceplate and using a boring bar in the lathe. You need a good-sized lathe to have the mass to handle that setup, so that probably wouldn't have worked for me.

[@wi11y1960]

Another way could have been a end mill the diameter of the counter bore. That would have been closer to what we learned to do when I attended Pasadena City College.

[@joshward7896]

Or....4 jaw chuck with small plates and junk and the 5/16" hole with a plug with a center hole. Then just a face cut as usual on a lathe. The plug could bear against another piece of junk within the casting, this way it wouldn't need a step fro thrust. Rubberbands and tape can be used to keep the whole thing from killing you. I love the soda can material.....006 quite often.

[@19441978]

Quinn, I have built several of these kits and I know the problems you encountered. On a Redwing hit and miss engine I built, I had the same problem with running out of room when facing the end of the casting. Even though I have a knee mill with a lot of travel, using a boring head still ran out of room. What I wound up doing was using a large strap clamp and fixtured it to the front of the table utilizing the T nut slot. This enabled to gain me enough room so I could use the boring head. Would that have worked on your mill, as I noticed you do have a Tnut slot.

[@Blondihacks]

Sadly no, Y axis travel on this machine would not allow that. Spindle doesn’t even reach the edges in the y axis.

[@19441978]

@@Blondihacks Gotcha. Enjoy your videos little lady, I think I have watched every one.

[@Rangemaster26]

For your flycutter, since you're cutting soft cast iron you can use a drill blank (re-harden it if you need to) or use a piece of round carbide and grind a flat with a cutting edge on it. Kinda like a round lathe tool bit. I've done it and it works great and you don't need to square a hole.

[@keithnoneya]

That was pretty nice BH. That fly cutter in the lathe, with the part sideways on the cross slide, then feed it in like you did on the mill would have worked too. However I liked the vertical position on the mill because you can actually see what going on during the facing, and it looked cool on the camera to for us viewers too. I love your humor in the video too, and yes we know you could have dropped that part on the bench every time. Next time get it to stand up on the end when it drops.

heres where a facing/boring head comes handy ! like a narex one !

[@AJMansfield1]

Another approach to getting perfect concentricity here (not that you really _need_ better concentricity than you got) would have been to just turn the collet boss on the lathe, then mount it in the mill collet, clamp lathe tooling to the table, and turn it the rest of the way on the mill using your XYZ feeds to move the lathe bit relative to the spindle.

[@markfoster6110]

Dam good job . Very well explained . When drinking cutting oil Mae sure it has stainless steel swarf in it so much better for inner health !

[@terrytopliss9506]

Well done Quinn,that was spot on.😋

[@cjtoombs7473]

Another way to make that square hole is to mount the part on the mill table and use the z feed and a tool ground for slotting to cut it out. It could be done on a lathe faceplate using the carriage movement as a shaper as well, but you would need some way of indexing the spindle. If it’s not an operation you plan to do more than a couple of times, filing might be the most efficient way, though.

[@Blondihacks]

Yes, that would have been a cool way to do this!

1:59 A lathe suddenly looks suspiciously like a horizontal milling machine to me...

[@Corbald]

Back when I was a 9-5er, working at the shop, the mill went down for some time. Burned out a hard to replace part. The 'machinist' on hand used the lathe as _exactly_ a horizontal mill for about two months, until the owner got around to replacing the part in the mill. The only issue is all cuts can only be made on two axes, depth and 'X,' but it worked just fine. I'm convinced that the 'missing link' between a lathe and a mill is a mickey-moused lathe in a horizontal milling configuration.

@@Corbald I don't know if anyone still makes them anymore, but you used to be able to buy a milling attachment for lathes that replaced the compound slide and gave you an extra axis.

Hi Blondie, Don't be afraid of carbide insert tools for hobby lathe. I have a smaller lathe and have no issue using them. Especially on aluminum and hardened steel. Propper insert does not know the origin or rigidity of machine. It jus does its job. And also - for delicate work on stsinless I use Alu insert. It does not last long, but cuts away better tha SS rver will, with low spring effect on long overhang. For aligning thing discs in lathe chuck - try a bump tool. A simple project: drill M6 hole in old brazed carbide shank and bolt on the ball bearing. Try it, you will be suprissed 😉

[@MrCrankyface]

What seems to work best for breaking chips on aluminium for me is tons of RPM and feed. I tend to use inserts but I will run around 350m/min or 575fpm and feed 0.15mm/6 thou per rev. This usually breaks chips quite reliably with cuts between 0.1-0.3mm radially using DCMT070204 inserts which can be find quite cheap on ebay and such. I think our lathes are fairly similar in size and construction(I have a BL250G). Start the feed, stand back and watch the spray of chips! :)

Yah, that’s what I do as well, and it helps, but my lathe can only do so much. What you saw there was max RPM and max feed on this machine.

It's surprisingly easy to make a nice square broach on a lathe. It's quite a bit harder to make one that does a good job in cast iron, though. (You can offset the tailstock and then cut a thread whose tooth profile is a cutting edge. It's a very fast way to make a wood broach, and the helical cutting edge means a very smooth cut. It's also a lower force solution than a mortising drill.)

[@jackgeedubs1855]

@@smellsofbikes how would you determine the depth of cut though?

[@smellsofbikes]

@@jackgeedubs1855 The ones I've made are intended purely for through broaching, so if I wanted an 8mm square, I'd drill a 7.8mm hole, and cut a broach from 8mm square stock that has a 7.8mm cylindrical start on one end, then has a positive rake tapered thread transitioning from that out to the 8mm finish width.

You could bolt the arbor to the cuter head with an eccentricly placed bolt hole. Arbor and tool are concentric (starting out) but the bolt hole connecting them is off axis. If it is only ~5 thou of axis you could get 10 thou of adjustment by rotating the arbor relative to the tool. Btw, I'm a big fan😊
