Re: LMS Wood Turning Tool Rest, needs mods out of the box?
John
I purchased the wood rest package from LMS also. Most of the time I put a round bar in the tool post since it is quick and most of the time I am just putting the final contours on the piece being worked on. Here is a photo:

Some strap clamps that I had the impression were small enough for the micro-mill (huge in reality) that I gave someone who forgot to take them with him :-) worked out pretty well for jacking the whole assembly up enough to get the tool rest down enough not to wobble for the time being and up on spindle center! The original bolt for the QCTP worked out well to hold it together. About a 3/4" spacer block would probably be better, but you would still have to completely remove the tool post to rotate it. Seems pretty solid, but I have limited confidence in that roll pin attachment for the rest itself, we'll see. I think the support shaft might be better fitted than the one you have. Added some pix of the fix to the page: Thanks very much for sharing your fix, I'll probably replace this kluge I came up with with something along the lines of what you did. Take care, Vikki. |
Re: LMS Wood Turning Tool Rest, needs mods out of the box?
Vikki, I took some poor pictures and they are posted here with some
notes If you have any questions let me know. In fairness to LMS, the spur center is very nice. If I want to do something quick though, I just somewhat round one end and put it in the chuck and put the other end up against the live center and turn the end near the live center round, then put that end in the chuck and it works out pretty well.

Re: Motor Temp Rise on the HF 8x12-14

Hi,
What might be missed is that the motor is running unloaded. While it is not at all unusual to run the motor for minutes at a time, the temp rise for an unloaded motor running continuously for 1 hour is interesting.

Chris, a postscript. Warco's stand is expensive for what you get, so save your money and make a wooden one. No need for massive timber - the lathe is probably lighter than you are, and chairlegs are quite slender. 2x2 would be more than adequate. And think twice before getting the vertical slide. I rather regret buying mine. As it comes, you can't attach a machine vice or other fixings to the front without a lot of overhang. Put the money towards the milling machine which you will soon begin wanting.

Re: LMS Wood Turning Tool Rest, needs mods out of the box?
Vikki, I bought it and was not very pleased. As you saw, I could
never get it to the right height. Plus the tool rest was not rigidly attached to the round bar portion of the post which controls elevation. My first attempt was to fabricate a wooden block to fit on the top and inside of the tool rest and tapped the rest and that fixed the height problem. The rest still jumped around in use so I drilled lengthwise from top to bottom through the rest and the post and inserted a machine screw ( with the nut on the bottom ) and that worked to make it more rigid. I grew unhappy with the way the rest attached to the tool post and ended up making a very simple board that clamps to the ways and mounted the tool post in that. I am not sure what you are asking when you asked about thread on the center.

LMS Wood Turning Tool Rest, needs mods out of the box?
wrlabs
I ordered the wood turning tool rest kit from LMS (we'll avoid
mentioning the nightmare getting it from UPS): Granted, wood turning is new to me and I *am* fairly clueless, but it seems that the actual tool rest itself won't go up to more than about .425 below spindle center without the post wobbling. From all I have read so far, I want this on spindle center to do scraping before I do other things to learn and be less dangerous. Not sure if I need to either shim up the toolpost or make up a replacement pin for the tool rest itself to get near spindle center? Also, anyone know what the thread on the center that comes with it is? Not planning on doing a lot of wood stuff with the lathe, but in the process of making "simple syrup" I ended up with rock candy and broke the honey "spoon" and wanted to make a replacement myself :-). Seemed like an handy thing to have in case I do want to make anything out of wood. Any thoughts appreciated! Thanks & take care, Vikki. |
Re: Motor Temp Rise on the HF 8x12-14

Hi Ian,
The motor runs fine, just a bit hot which appears "normal" for this motor. All the connections are fine. When I worked in a Standards Lab we would do these measures, but I'll leave that for a future project (not really...<smile>). Thanks, DBN steam4ian <fosterscons@...> wrote: G'day DBN & Mike. The temperatures you have recorded do not seem unduely high. You need to remember that the insulation is most likely rated for 90 degC. (161 degF) temperture rise, this is typical of modern electrical materials. First question. Does the motor pass the smell test? There may be a sweet oily solvent smell, thats normal, but an acidic or acrid smell indicates trouble. Question 2: Do the terminals get hotter than the rating of the connecting cable insulation? The connecting cables with PVC insulation generally have a temperature rating of at least 75 deg.C. After extended running and with the motor disconnected at the wall outlet, measure the terminal temperature (you can get temperature marker crayons but a finger will do). Note, higher temperature rated cables are often used for machinery wiring, often rated to 110 deg.C; this grade of wire is used in fluorescent luminaires. The only reliable winding temperature measurement is to measure the winding resistances when cold and hot and compute the temperature difference. Handbook type advice would generally assume this means of measurement. I would suggest that if the motor does not smell bad, the terminal temperature is less then the connecting cables insulation temperature limits and the surface temperature of the motor case does not create a fire hazard then all is well. Always keep flammable materials, dusts and fluff away from the motor and ensure the air flow is unrestricted. Then if the motor does give up you only have to replace the motor not your house.

Re: Salvaging aluminum scraps
Hi Mike,
I am into aluminium casting. The problems with swarf and chips is that they high a high surface area and when you try to melt them you end up with a lot of dross (oxide) and very little metal. Industrially they would compact the chips and melt under an inert atmosphere to avoid these problems. The same goes for drinks cans. The metal is so thin that you end up with musch dross and very little usable metal. There are many aluminium alloys and they are compatible. However, most turning alloys are not ideal for casting. It can be done but it is much easier to cast proper casting alloys that contain a high silicon content to give good fluidity. Drink cans are nearly pure aluminium and the metal is very soft when cast. Iron is small quantities is not too much of a problem although if too much gets into the alloy it forms hard intermetallics that make the metal brittle and very wearing on lathe tools. Many amateurs melt aluminium in mild steel crucibles and get good results. If you want to separate aluminium and steel try using a magnet. Free machining steel make small chips that is easy to separate with a magnet but once you get curly swarf mixed it is almost impossible to separate different types easily. I do not think there is so much of a problem regarding hazardous fumes in melting aluminium swarf as long as you don't contaminate it with plastic swarf. PTFE swarf produces highly toxic decomposition products, PVC is also hazardous.
