yea! ya centerd the stock! :) good job!! gotta love that stuck spegetti string! haha, i have done a lot of delryn over the years for powersports parts and even special tools for assembling suspension parts on powersports. that spegetti has caused me to destroy parts of not careful. it can snag and jerk the part and ruin it. sucks when it happens. last time had 4 hours on a custom seal saver and had to start over as it trashed where the part meets the shaft lip.

When milling stringy plastic, use a shop vac to suck away the swarf. I make plastic parts whenever I can. Sometimes they're good enough. From that point I decide if a metal part is worth the effort. I can proceed with the confidence of having already made the practice part. Making Morse tapers is hard to get right. Machined blanks come in any attachment type for cheap & are impressively accurate. Available from China, India, Amazon, etc. I've been very happy with the quality of very inexpensive blanks.
@JIMMY916Ай бұрын
Thank you for your suggestion to use a shop vac. I bought one yesterday. But I don't know how much it will help me because the chips are wrapped around the part. I will see. As for morse tapers, it doesn't help me to buy one for this project. I had no way to join the outer part with a morse taper bought. Thank you very much for the information provided !
@pvtimberfallerАй бұрын
Keep your hands clear of ANYTHING when it is moving. Those nice soft chips will wrap you up in a fraction of a second and either wrap you around the spindle or cut off fingers etc. We had a millwright get a string wrapped around his wrist and almost cut his hand clean off. Do you have a copy of how to run a lathe by the South Bend lathe co.? it is pretty much the original go to book for lathe setup and operation. They go into centering stock for turning. If you can’t move stock with that machine try grinding high speed steel tools, they take a lot less horse power. Also your tool is sticking way too far our, that will cause chatter.

Well your ingenuity is definitely in full swing. What you built here is impractical and completely overkill, but it's cool and it works. As an added bonus you hit your tolerances and got good experience. Personally I started out with and still use a "bump" centering tool, it's basically a bearing on a stick. You could use your homemade burnishing tool for this (you call it a flattening tool). You just move the tool in while slowly spinning the material until it centers itself from bumping into the tool. Once I saved some money I got a 3-jaw chuck that mounts in the tailstock to hold heavier material while I set up my steady rest.
@JIMMY916Ай бұрын
My steel bars are not perfectly round. The cone tool averages the circle and finds the best fit point. If I want to find the center of a part in the shape of a hexagon or square, what can I do with the burnishing tool or something like that? With this tool I can find it and drill at the same time any shape of a part. Thank you very much for your comments ! It means a lot to me.
@skwerlzАй бұрын
@@JIMMY916 Look up a tool called a "lathe spider." It's super simple and solves the problem of square/hexagonal stock with both steady rests and bump tools. I've got a couple of them I've made over the years to tightly fit different size stock I work with. As for your cone you're on to something there, it just needs refinement and iteration.
@JIMMY916Ай бұрын
Yes, it is an interesting tool ”lathe spider”. But I don't understand how I can use it if my part has a diameter, let's say 40 mm, double the diameter of passing through the chuck of my lathe ?( My plastic part from the test have 40.) That lathe spider is only for diameters that are smaller than the hole in the chuck ? If so, I believe my concept is better :)) Maybe we can improve it together...
@skwerlzАй бұрын
@@JIMMY916 Yeah I probably got the name wrong, might be a "cat head". So many odd names for things. It's just a ring with some bolts in it to center your material. I've made a few over the years to fit common sizes of hex and square stock. As to round stock never being perfectly round - it's also never perfectly elliptical and a cone relies on the saw cut to be perfectly straight besides the roundness of the stock. Ideas to improve your design - it definitely needs shortening. A shallower cone would let you shorten the travel, making it much shorter overall. Going to a 45 or 50 degree taper would take a few cm off of it. It would also be nice to be able to remove it from the tailstock without removing the tailstock from the lathe. Maybe if it slipped off of the morse taper like a socket? Something to think about.

I wanted one all through high school and finally saved enough to buy one. Total piece of crap. I was so disappointed. Besides awful construction (Some are actually built well) the biggest problem is the design. If you notice the tailstock doesn’t overhang the bed and so it has to be extended all the way to be used. Also because of this you can’t cut from the tail center to the chuck, you lose 2-3” on one end or the other. The mill head is too high above the table so you need a riser block to do most work plus you can’t clamp it to the column tight enough to take any kind of a cut. Still beats a hand grinder.

@@pvtimberfaller My opinion about this combinated machine after six years of ocasional use. - - - 1 Because of the milling table , long pieces cannot be turned in one pass. 2 The lowest speed is only 160 rpm. 3 The guides are always exposed and it is mandatory to be greased very very often for smooth operation. 4 The chuck has a diameter of 130 mm. No independent four jaws for this diameter. Only 125 mm. 5 The gear change is made only from the belts. +++ 1 It is very precise and no deviation. 0.01 mm is not a problem 2 Is quite robust and heavy (about 300 kg) 3 It takes up a little space for two machines. My workshop is tiny. 4 Its engines can run continuously without burning out. 5 Its price.

I forgot to add the to high of speed thing. Mine was smaller, I think the type you have came out a few years later. I had to remove the chuck every time I wanted to use it as a mill. They also had metric feed screws and imperial dials so the dimensions were never correct. They offered a planetary sheave that would reduce the spindle speed 2:1 or 3:1, I don’t know if they have that for your machine but it would be a very good modification.

At 45:35, after drilling axial hole, you test fit the centering tool and say "I think this hole is about 2 millimeters bigger" and "centering tool will be tightened with a screw." That would put it 1mm (0.0394") off center. Eventually I realized you must mean 0.002".

Jimmy, thanks for entertaining me on this Saturday morning in S. Florida. Only time will tell if it stays true to center. At about @16:00 you were setting up Center to copy a Morse taper using a Morse Sleeve. For those of us with easy access to the spindle's Morse Taper we could simply hold the Sleeve between centers. Then we would only need the DTI to set the Compound angle. Capice? Thanks again, Wakodahatchee Chris
@JIMMY916Ай бұрын
I don't have a long tailstock tip and my live center doesn't have the necessary precision for something like that. Anyway, my centers can't get that close. I don't think that another method would give better results considering the accessories and the lathe I have. Time can certainly tell us a lot, but I don't know what role it will play here. One use in cycles of 30-40 sec. I'm sure it can't cause any wear and tear. I certainly don't worry here. Thank you very much for your comment and I'm happy for the pleasant morning to which I also contributed.

I don't know how I would be able to verify such a thing. No metal or plastic bar is perfectly round from the factory (with some exception). There can be no question of absolute precision at this stage. It is an approximative center. No method in this world can find the perfect center of an imperfect circle. My intention was to present more of a concept. I'm sure you can draw your own conclusions whether it's a good tool or not. That account, I assure you, makes finding the best necessary center for the live center. I will always use it from now on. Thank you very much and I'm sorry I missed to film this aspect.

@JIMMY916Ай бұрын
There are only two screws. The first, wich is the smallest, fixes the drill bit, and the second screw (larger one) fixes the central shaft in which this drill is mounted. All that needs to be done is to loosen the big screw and take the axle out. ( we don't dismantle anything ) After loosening the screw, the spindle will be pulled out. After changing the drill bit we will insert the shaft back and tighten the screw with an allen key. I really regret not showing this in the video. I simply omitted.
