Awesome video! Was very impressed by the aluminum tape to step granite improvised portable lap along with the initial demonstration of how Reynolds Heavy Duty Tin Foil makes an amazing substrate for holding lapping charge. I had acquired a 2’x3’x4”black granite surface plate from a local equipment rental company but put the reconditioning of it off due to lack of ability to do so with my current equipment. Seeing your demonstration really has opened up the possibilities for me to think of tackling this now. So a much appreciated Thank You for taking the time to make this video and sharing your knowledge and insights gained from experimenting.

Hi Tom! Thanks for great video, as always! I was that "one guy", very happy to see you found my technique useful. Little tip (reduces tearing of foil and edge "smoothing") : try putting just a drop or two of viscous oil (200+cSt is excellent) to your surface plate, add foil and push away all the oil with your shaft or a rubber roller (works even better). Surface tension forces hold the foil better than adhesive tape. For small parths with low dimension rations we use a special holder, it looks like a small cap for a part, with a round socket on top of it. A bent rod with a ball on it goes into that socket, making the lapping force always sentered on the part, making a point contact system. Automatic lapper with a static weight added to all the parts does the same job. Will try to make a full video with all this things to complete the topic. Thanks again! Pavel

@ROBRENZ and Oxtoolco Dumb question here; genius technique, however does one get aluminum/dissimilar metals lapped into the ferrous material you are lapping and hence set up future corrosion sites from dissimilar metals in the surface of the work piece being lapped on the aluminum (i.e. surface corrosion pitting starts to happen faster (over time) than not using aluminum ?), OR does all of the mechanically dissociated aluminum 100% turn to aluminum oxide and is relatively inert / inconsequential ? [Might be worth testing out ? Maybe ?].

A good use I have found for my HF magnetic level is to stick it to the leaf of my sheet metal brake. I zero the level with the leaf at rest and then note the angle when I stop a bend. That way I can return to the same point if I need to bend a little more or bend multiple pieces at the same angle. I actually keep a log of all my bends, so when I need to bend a sheet I have a log of materials, thickness and angles that get me the angle that I want very quickly.

On the lapping with aluminum: during my apprenticeship I learned the same trick except with paper and it served me well. We worked with D5, and a guy who worked at Timex (those guys could do small work) showed me how to use paper on a steel surface plate soaked with kerosine. We would use reducing grits and get flat mirror finishes in no time. And you could peel off the charged paper, let it dry and use it again. Later when I was doing precision die work in carbide, I used the same thing with diamond paste which also worked well. The aluminum trick looked good but I saw you fight to keep from snagging it. This happened occasionally with paper, but with the kerosine (or any light oil) the paper adhered to the lapping plate like it was glued there. I never checked for flatness with a optical flat but after your experiments with the “cheap Russian flats” I ordered one and now I can give it a try. But the paper/light oil/diamond paste worked pretty well on carbide and were much less trouble than the foil. Stay with the nerdy stuff! It’s fun for many of us out here in Internet country.

Great idea on the aluminium lap Medium, far easier, and less expensive than the old Lead (Pb) sheet. From a metallographic aspect, polishing samples to 0.5 micron for example, from 120 grit, 240, 360, etc to 1200 abrasive paper on rotating platens, then 6 micron, 1 micron. We rotate the sample 90 ° degrees for each grit, to check that each successive polishing has removed previous uni directional polishing lines, between each grit, the sample is washed to remove previous grit. 6 micron and smaller, we use rotating platens with different adhesive cloth naps, loaded with diamond paste and oil, a figure of eight action is always used here because the platen is rotating, using a fixed platen, then orbital action is used. Great care is taken to clean between each stage, using Ethanol, Acetone etc, with cotton wool and/or ultrasonic cleaning. Cheap toilet tissue paper will scratch the surface of most steels, you need a good quality named brand. Tip, if using a ultrasonic cleaner, then use a small container, just large enough for the sample with Ethanol etc, suspended in the aqueous US cleaning solution, don't forget to degass.

Tom, instead of taping the foil onto your plate, try spritzing the plate with water, lay the foil on, and squeegee the water out. The foil should stick to the plate almost like how tinted windows are applied. I do this on glass plates and it works for me. It should also help prevent the edge roll-off, by keeping the foil down at the edges.

Nice video to learn from. I use to do something similar to lap. But the trick that I was taught many years ago by an Italian mentor while doing my apprenticeship in South America. He would use thin construction paper about .5mm THICK or .020" thick. and no lighter fluid . He would also tape down to a surface plate. But I found it kinda hard to get that construction paper here in the USA when working as a tool and die maker. So I bought plastic shim stock from McMaster . It's sold in several thicknesses and sizes. And I can achieve the exact effect of flat lapping and you can also use a very fine oil. Nice thing about buying it from McMaster is that you can buy the diamond lapping syringes and the plastic shim stock and get in the shop next day.

The magnetic digital levels are fantastic to have around. When I helped my brother install new Rotary lifts in his shop I slapped two of them on a post, 90° apart, and had an immediate readout of both cardinal directions for mounting it plumb. So much easier that trying to read a bubble level, and surely more accurate. Good to have a known flat and parallel piece of metal to span larger surfaces (averaging a rough surface finish, for instance). A 1/2" square by 6" HSS tool blank is my personal choice.

I use mine on the bench grinder table to set angles. Very doubtful you could set any of those cheaply made non vernier equipped degree scales to +- 1/10th of a degree by eye and it's faster. With a bit of finesse you can even set grinder table miter gages by setting the bar against something that's vertical and fairly accurate then use the level on the working face. Maybe not quite good enough for grinding a threading tool, but for everything else probably good enough.They are a pretty handy little tool.

I have some pieces of granite countertop material (a local counter place has an outdoor dumpster for scrap, and they let me rescue some when I asked nicely), and I'm going to tinker with making little flat laps via the 3 plate method. That aluminum tape trick is just seductively easy looking. I get that the foil itself is nicely uniform thickness, but I wonder about the adhesive layer. I've been told that lapping film is superior to equivalent grit paper, because the thicker paper has too much 'give' to be precise. Would that apply to adhesive as well? Does the lapping process just cancel out that consideration?

If you face the peace of steel on a lathe (good one) you can get it flat to a 1/100 of a mm.He did video series in which he made his own laping plates by facing 3 discs on a lathe and laping each other.

I have a suggestion for the tin foil lapping. I think you'll get better results if you put a drop or two of mineral oil on the plate, something that has some modest viscosity; grease might even work but oil will spread easier on the plate. Use a flexible squeegee to get a nice even layer just the slightest wiff of oil then lay your foil out and use the squeegy (after cleaning the squeegy) again over the top of the foil to get the air out from underneath, it will also vacuum adhere the foil to the plate pretty good as long as you don't over do it with the oil.
