how to make a lathe variable speed

The friction caused the acrylic to get too hot. Made a lathe from a 1750 rpm cap start motor. my motor only has 4 wires, 2 brushes 2 coil. To achieve this without some sort of electronic control would mean an elaborate (read even more noisy) and large pulley system, and,c) if connected straight to the mains the speed regulation will be poor when load is applied to the motor. Then I began to clean it up.. If not you can skip this step. Make sure the alignment allows the coupler to easily slide back and forth. I like making stuff, and learning about how things work. Now we need to decide where and how we will fix the front and back faces. It also presents a safety hazard as attention is focused on the next task, while the lathe remains spinning and dangerous. The list is endless. Mine is a VERY snug fit and was nearly impossible to push up and down the rails by hand - which is partly why I wanted the lead screw.

It came out of some offices and as far as I could tell must have been part of a table or something. Here you go with measurements to 3 decimal places. This creates a braking force and the energy is dissipated as heat in the armature. Eventually you might want to step up to one of these. 100% is about 40-45 rpm, 50% would be have that speed., about 20 rpm. Here is what I came up with, how I did it, the parts used, and the results. To make yourself a load of wooden kitchen bowls, plates, utensils, etc. That's a hard one. Rockwell Delta 46-111 Lathe, Part 3: Variable Speed This will be my 2nd lathe converted to variable speed. 3. Variable speed control knob. (Dave Gingery) PS  to see more of what I have been up to with this you may want to check out my blog: www.floweringelbow.org Or if you want even more recent stuff, half finished projects and that sort of thing, like the Flowering Elbow page on facebook (also good if you want a quick response to a question). “With a variable speed metal lathe like the LeBlond RKL, you get the RPM to match up to your cutting feed rate and the surface finish you want on a piece,” Cook says. It cuts power to the NVRSS3 = Another relay that, when energized, completes a short circuit between the motor brushes.NVRS = The main on/off "no volt release switch".R1 = A resistor of about 10ohms (the larger the value the more gentle the braking effect)T1 = Step down transformer 240V to about 9VD1 = A diode that ensures the field coil is maintained in one direction. faffing around gives you away ou china. Check out Youtube Clough42 channel. Because they will be used to join on the bed of the lathe they need to be exactly perpendicular to the front and back panels.They also needed to be cut so that they hold the front and back panels at the correct distance - that is, the length between the drive shaft bearings. Here I made three mistakes - 1) attempting to make a monster leadscrew-nut from perspex, which obligingly snapped my extra long self-fabricated tap; and 2) using a leadscrew that was only 6mm diameter. CSA and UL Listed. I still wanted to keep an eye on what was going on inside while the lathe was running though, so the plan was to find some thickish perspex to cover the top. S1 = On button (push to make)S2 = Stop button (push to break) - if you make it this way S2 must be a very robust button as it will carry all the power going to the lathe. There will likely be 3 stator coil connections,2 brush contacts,2 tachometer contacts,and an earth connection on the motor frame. One of the down sides to modern series wound washing machine motors is that they are designed to go very fast, and when run on unfettered mains current will screech along at about 8,000 rpm with a modest load (as I already said don't run them unloaded). If you go with a variable frequency drive (expensive), it means that you will also need to get a three-phase motor and it will need to be larger than the one that you currently have to make … on Introduction. An "Electronic Lead Screw" (ELS) is an over-the-top way to control feed rates. It's just the bearing, no cap or housing or anything. After flirting with the idea of using a rewound microwave transformer (and discarding it as overkill), I came across an old-school Spectrum power supply at the local tip (which is essentially a transformer with a rectifier and smoothing capacitor) - just the ticket! As far as I know copper is better at conducting the heat, and aluminium at radiating it to the surrounding atmosphere. The aluminum was turned with a Korloy 9mm round carbide insert designed for aluminum. It eliminates all the change gears. I use some aluminium angle to bolt them in. ( any light hyd.oil for now ) Turn lathe on and rotate the vari speed handle all the way counter clockwise and hold that position for a few seconds. Also, no transformer, so 230V all the way. Reply Thanks to Westfw for the Eagle schematic 'able (https://www.instructables.com/id/Draw-Electronic-Schematics-with-CadSoft-EAGLE/). Making something that helps you make other things is very satisfying, particularly if you do it in a way that uses all your creative ingenuity. Snaps.
