Machining Hole Patterns in Stoker Engine Fixture Plate

I'm building a large fixture plate to be used in my G&E shaper. This fixture will then be used to allow the stoker engine to bolt to since it's footprint is much larger than the shaper table. This fixture will also be used for any other type of large work holding needs in the future.

It's SAE, not imperial, and yeah you get good at fractions. Although, except for drill sizes most things in machining are measured in thous (thousandths of an inch)

[@dayofmone]

I'm a second year apprentice in Germany and your remark in regards to your counterbore tool being too large with a 1" diameter for a 15/16 hole made me curious about the American size that would be correct. I am always on the look out to learn more, so out of curiousity I looked up the German standard: A 15/16 cap screw would be about an M16 screw with a 23,8 mm head, which would receive a 26 mm or 1" countersink. Your channel got me interested in metalworking by the way and inspired me to become a precision mechanik. I like how you often explain what you are going to do, it has taught me a lot already and I am looking forwards to learn more. Thank you! :)

[@philhunt9297]

My only suggestion would be for Adam to make a lockable rotating adapter for between the hook and chain on that Sky Hook so that if and when needed he can unlock and rotate whilst connected to Sky Hook rather than having to lower onto trolley - if these heavy lift jobs are going to be regular. HTH

[@markschweter6371]

I like those 'changeable pilot' counterbores! Same counterbore for different size holes.

Thank you. I hadn't thought of that way to find a true center. I usually use a small bit and see if it deflects but your way is much better so truly appreciated. Now I just need to buy myself that setup.

[@paulg3336]

Regarding the tool trays: Fill the back side with epoxy or polyester resin (composite resin, not body filler). You can use fine gravel as a filler so that you don't need so much resin. I do this with the flimsy vacuum molded styrene trays you get in today's tool kits - it turns the flimsy tray into a tray that will last forever.

[@larrysperling8801]

all those material handling gadgets are really coming in handy. for years i have used the pointed edge finder to center up holes for drilling. i drop the pointer into the center punch and let it sit there while you adjust the table you can feel the slightest misalignment with your finger nail. i dont trust the wiggler because the point can take a set when you drop it into the centerpunch . you really need to recenter it ever time you hit the center punch to be sure its still on center.

[@utidjian]

The wiggler is actually really easy to see when it is dead on center. The tip appears to stand still and stop spinning. The slightest bit off from being off center and it "blurs." Try them side-by-side sometime and I bet you can't tell the difference. I find the pointed end of the edge finder is useful if I have to locate off a small hole that is already there. The wiggler with pointy tip is useless then and the edge-finder with pointy tip works very well. So many ways to skin a cat.

[@larrysperling8801]

@@utidjian i guess its its all a mater of taste David. both will get the job done. i had a tool and die maker friend who would use sewing needles stuck into a blob of clay at the end of a milling cutter he would start the machine and center the needle like a wiggler and use it to pick up features on his work.

[@utidjian]

@@larrysperling8801 Oh for sure it is a matter of taste. I guess that is why there is a still a market for edge finders, wigglers, optical centering scopes, DROs, dials, Blakes, DTIs, layout plates and tables, surface gages, height gages, CMMs, electronic probes, rulers, scales, hook rules, gage blocks... and dozens more that I have forgotten or I am too lazy to type in. I never used the needle and clay method though I have heard of it. It has the distinct advantage that one does not have to swap out the wiggler for the tool each time. Also easy if the spindle speed is low or can be lowered easily.

[@desolatemetro]

Definitely going to grab one of those wigglers for my drill press. More precision than I need, but will help correct for my lack of skill since I don't use it for metal that often. Great tip.

I think I'm gonna invest in one of them skyhook type cranes, I always laughed at um, but last weekend i pulled my back out heaving a large cube while setting up a casting to be machined on my bridgeport mill.

[@CrimFerret]

The Skyhook seems to be working really well and being able to attach it to the bed of the various machines makes it really handy. As for the lift cart, there are two types of people, those who have one and those who need one and that goes for even if you aren't doing machining. The 1 ton ones lift high enough to line up with a lot of pickup beds.

[@markvanappel4875]

a good way to remove dust and steel particles from the magnet is any kind of adhesive tape.

Thanks, this is such good information for a beginner. Would you cut a large counterbore in the same way? Let’s say for a hex head bolt, and allowing clearance for a socket.

[@Ddabig40mac]

That certainly could be done in similar manner. It might require 2 or more counterbore steps to open up far enough for a hex head and socket.

[@ronalddavis]

the counterbore itself can be done with a centercutting end mill

[@dolomighty74]

I'd like to see the wiggler action better: may i suggest a small mirror on the side, to see the other angle also?

[@peebee143]

Looking forward to seeing this work on the stoker engine.

[@MrRedstoner]

19:44 interesting effects on that DRO screen. I assume it's the camera almost syncing with the screen refresh.

[@alexku8452]

Yes, it is the same effect that makes wheels and propellers or rotors e.g. on helicopters look like not moving or spinning backwards. LEDs usually flicker, also we do not usually see this due to either the frequency or some kind of inertia in some LEDs (mainly those that use chemical coatings to create a certain color, but actually it is 99 % frequency) If the camera shutter is not synched exactly to the LED frequency they will flicker. same with fluorescent lamps. sometimes depending on the chip type in the camera you may also see those brighter and darker stripes vertically rolling through the picture. To avoid that effect you would have to run the LEDs on actual DC (which is rare) or use a shutter speed that is slower than the cycle for the LED. In the LEDs this flicker is usually generated by how the LEDs are driven, or more exactly which power supply is used. In the simplest case (most LED light bulb) it is just a capacitive dropper, that more or less cuts the AC sine wave in half, so you will find frequencies related to the AC frequency, 60 Hz for the US and Canada, and 50 Hz in Europe for example. Better capacitive power supplies invert the "negative" partof the sine wave so we get double the frequency. Only the "inertia" of our eyes allows us to not usually see a flicker. Incandescent bulbs flicker at twice the AC frequency as well as the currents sine wave peaks at positive and negative and in between crosses zero. it is just that the actual glowing of the filament wil dampen the flicker as it does not cool down fast enough to make it visible. Some LED drivers use smoothing capacitors to generate such an effect. Less an issue are switch mode power supplies. those internaly use a chip to change the frequency to something in the range of 30 kHz, which allows a lot smaller transformers to be used. To capture that flicker you would have to borrow a camera from the slow mo guys to make it visible.

[@colinwilks9232]

Question Adam, what could happen to the drilling of the pilot holes if you didn't spotface first?

[@johnbirkholz994]

This is a good question. Spotfacing helps ensure that the pilot drill stays vertical and doesn't "walk" or bend, which results in a non-vertical or oval hole. At 6:44 Adam gives us a great head on view of the larger drill bit where you can see the "flat" section in the middle. With a small pilot drill that can bend, that small flat spot may cause the bit to skid over the material surface before digging in and starting the hole. By spotfacing and providing a countersink for the pilot drill to match up with, you know it will start drilling in the right location. I don't know if we see the tip of the spotting drill in this video, but from what it looks like based on the chips and how pretty the countersink looks, is Adam has a special grind on his spotting drill where that center flat on the tip is removed, essentially the two flutes meet perfectly in the middle. It is also relatively wide and short which helps with rigidity, again helping ensure that the countersink it leaves is centered in the correct location. We use center drills a lot at work, which serve the same purpose but only have one flute and a stepped grind. upload.wikimedia.org/wikipedia/commons/thumb/d/df/CenterDrills123456.jpg/400px-CenterDrills123456.jpg

I've made many plates like that on a radial using only layout lines and a dead center, big Ooya radial drill. Thanks for the video, Will

[@bobvines00]

Adam, when you chamfered the counterbores, why didn't you chamfer the "inner" hole too? Don't the SHCSs have enough radius under the head to interfere with a sharp corner? I'm not trying to be a PITA here, I'm just curious and interested in what you and others say about this "possible" interference.

[@utidjian]

No need to chamfer the inner hole because he drilled it for clearance. A clearance hole is larger than the OD of the bolt under head radius. If you are still not sure look up what is meant by a clearance hole.

[@bobvines00]

Which is why maybe putting out 2, 3, or 4 videos in a week might be better for others. Unless you really are doing this job on a weekly/weekend basis, in that case I totally understand why you don't.
