U using dowel pin size...mm size?

I put a 4mm dowel in the collet, colour it with a dark Sharpie then move it towards the edge whilst it’s running until the ink starts to wear off, zero it on the DRO, lift it up and move it a further 2mm and zero it again so my centre is above the edge. Seems to be accurate to 0.01mm.

try filling from the bottom up, with vents on top.

I was wondering why you don't put the coating on the back of the foam cast ? Does it help thanks

Thats a very high laundry line😅

started watching for the techniques, now I'm intrigued by what you're making. I'm retired FF and saw the IAFF, what are those? They look really cool.

As long as you are the person who is aware of the safety risks then it is only your fault but just turning spindle by hand against a known diameter of a pin or a certain gauge block would be a better way than the paper trick as not all paper is always a constant thickness all the time love the videos

Great video brother, Lots of good info and tips. Thanks for sharing with the community. 😎😎⛏⛏🔥🔥

Nice job🎉

🎉🎉🎉 Have you tried usin a bottle of 91% isopropyl alcohol in the plaster. about 10% of the total water. It may help with air bubbles. Or about 15-20% of 70% isopropyl alcohol. I guess more alcohol would only make the plaster dry faster. The lower surface tension of alcohol should reduce the amount of bubbles in the plaster. Id try it with small amounts first, and use more alcohol in place of water in the plaster. Until the dry time and surface tension is ideal!🎉🎉🎉🎉

This seems like a great idea. I am tall and have a bad back. I hate bending to use my lathe. I had thought about using a big piece of tubing to rase it but was worried about introducing vibration.

Would look cool if you machined the surface or at least the letters

at 17:00 what is getting the grooves? It is repeated pressing (forging) by ridges on that rotating tool ? The diameter of job need to be precise so that whole number of ridges make the perimeter

Can you shorten my shift shaft for me

Jealous of your lathe brake haha, i have to always think so far ahead for everything i do

I teach the paper trick with my new students, who are totally green, BUT i use a bit of spit and stick a postage sized piece to the jaw. Plus I hand spin the cutter with it in nuetral. Personally I run the cutter but thats not a good idea with first timers. The accuracy could be questioned versus more sophisticated special tools but they may not always be available wheras paper is always there. Great video, going to let the students watch it next lesson to show all the other ways you used.

7:47 user opts for tattooed finger ring, genius! Thanks for your work on your channel.

For many years I just used a 1/4" piece of silver steel in a drill chuck.....OK so it probably will not be that accurate but good enough and quick for most work.

Liked the comment about the man who was always talking. The Lord gave us two ears and one mouth for a reason! You're supposed to listen twice as much as you talk!😉

I tried these methods and now I am always on edge

Nice

Great application for a sand cast part. I’ll be casting wheels n knobs on saturday

Hello want to be trained on how to use oxygen and acetylene CNC flame cutting machine

Mom told me no one ever learned anything with their mouth open!😂

For paper touch off, use a Zig-Zag with a little oil to hold it in place. Works like a champ. The Zig-Zags in the white pack are 0.001" thick quite consistently.

Consistency of gravy. 👍

Can you show a video of one being put back on?

Thanks

Do you think the average guy could build this😂

I’m a retired tool and mold maker of 40 plus years. I’ve got to say that the paper methods with a live spindle would get you a written warning at the shop I started in. We did however occasionally use a feeler gage and manually turned spindle to get a touch. The only other thing I take exception with is your edge finding the moving jaw side. I’ve always been trained and passed on that in most circumstances you edge find the fixed jaw side. I also prefer to use the edge finder in a collet,i find it’s more accurate. To find the center of a diameter you should edge find in one direction then the other and repeat it as you will not be spot on with the first try. Happy machining!

Our building Engineer at Winnipeg's Seven Oaks General Hospital was called to Emergency Dept and was summoned to remove a grinder disk from a grinder that dug down all the way to the 'axcel' into the top of a guys skull......(still attached to the grinder and stuck in the guys head) .......fortunately it was only a 5 inch disk and patient survived.

In the 60's when I started, we put a 1/2 dowel in the spinning chuck. Coated it with the good old "red grease pencil" ( the kind where you pull the string to access more tip. Kept in shirt pocket right next to 6" scale). You slowly touch side of part with spinning dowel. When red wax appears on surface, you're 1/4" away from edge of workpiece.

quiet please lol

Hold the part upright in the mill vise between two vee blocks - one against a stop. Find the center and cut all 4 sides in one setup with the side of the cutter all using the same offset. It will save the corners of your endmill & get a much better finish.

Can you show some methods finding the center from each side without a dro.

Couldn't you make an adapter for electric edge finder to fit one of the collets you do have?

When using the paper, wouldn't it be safer to use a 1/2" dowel pin instead of an end mill? Also the dowel pin wouldn't damage the work piece.

They make an edge finder where the end piece is 0.5" instead of 0.2" so it can find the edge of any diameter rod (just remember to subtract 0.25 and not 0.1)

The equivalent of the guy who swaps a fuel injected engine into a vehicle then slaps a carburetor on it because he thinks it's simpler. All you had to do was jumper the thermostat wires on the controller and hook up power and ground and you'd still have all the safety systems in place.

We used a cigarette paper and stuck it to the work with a bit of water ( or spit 😉 ). Probably a little bit safer than holding the paper.

I loved this wild experimentation, you were totally safety minded, you were doing it outside not in the Kitchen!

So cool you built this with your kids! 😊 This experience from just building on the cheap to the produce grown. 🤙

I thought this video was for lost foam, not plaster....

Great info Thanks :)

I had that problem with my moped many years ago but I just put a piece of thin plate from a soda can around the shaft to get a tighter squeeze. I think it held up quite well but not as new splines.

So cool! Thank you for putting this out there.

As a machinist, from a safety standpoint I was screaming this whole video. Holding rotating equipment at thousands of RPMs is just plain egregious. Add to that the potential pinch point between your hand and the tool post makes this whole process unthinkable. Please, anyone watching this video, DO NOT replicate the actions this guy took here. The fact that you survived is the truly amazing thing here. This process should ONLY be done with properly rigid holders. AT THE VERY LEAST, use a Jacobs chuck in the tailstock, NEVER your hand. I cannot stress enough how unsafe and terrifying the actions you took are to me. Never should hands be this close to rotating equipment.

I have seen another guy do some very tight tolerance stuff with this process and I can not understand why anyone would do a different process like PLA etc.

I use the smallest harris cutting tip to cut 25mm plate @ 330mm minute 45bpsi oxygen and lpg @ 10psi
