Thank you for anyHi Ken: Like most DC brush motor controllers you can reduce the speed control to the point the motor stops turning. But this probably doesn't mean that you can stop current through the motor by turning the speed control to off. In this case the motor is still "on" but it just isn't turning. I think it would be normal to feel some residual effect and to truly shut off the motor requires the main switch. Maybe the speed control should say 0 rpm rather than "off". my thoughts, Mike... |
Speed Control
wb2tdg
I recently bought a 7x12 Homier and so far so good. The question I
have is when I shut the varible speed knob to off and manually turn the lathe backwards I can feel a restriction. If I turn the electric switch to off it goes away. Its like the electronics are holding it from being turned easily. The main question is will this hurt the electronics? Its a pain to turn off the speed control and main switch just to turn it backwards a turn or so. When it is in reverse the same thing happens. The restriction is felt only in one direction not the direction that forward reverse switch is set. Thank you for any help Ken |

Make up a few and show people what you can do. That's the best sales tool. You can use the stock removal method and only have to cut metal away. Then find somebody to heat treat and temper them for you. Add the scales of grips and you have a knife. You should look into leather work, a good knife is not useful unless you have something to carry it in. Jerry At 02:30 AM 11/29/2002 +0000, you wrote:

yes that I heard was also referred to as watered steel, but the
concept is awesome and must take forever~! I bet you charge and arm and a leg for thatif you ever make them... Maybe when I am older and have a good paying job I might get into knife making, there is a profit to be made, some old timers these days have money and want a special knife made for them.

Damascus steel, is bars of steel are forged together, much folding of the metal goes on during the process. You must flux with something that contains borax, or you can use the stuff at from store (20 Mule Team Brand, 100% Borax) Some Fluxes are designed for gas forges or coal forges. You make a billet out of several layers of steels, when different steels are layered, you get a layered effect in the finish product. I sometime add a layer of nickle or copper. Damascus is prized because of the patterned product that is created. It's a lot of heat in the forge, hammering, fluxing, folding and repeat the process many times. There are added steps to get different patterns. To do it, isn't that difficult, it's just time consuming and right equipment does get a little pricey, but lesser equipment will do, just add more time because of the equipment. Hope this gets you excited to do knives and start building your smithy. Jerry At 12:41 AM 11/29/2002 +0000, you wrote:

The only thing I don't do is mine and refine the steel/iron. I have several heat treat ovens, have a working knowledge of heat treating and tempering. My big sellers are hunting and fishing knives. Mine aren't pretty, but they are next to indestructible. I do make Damascus and other specialty steels for knife making. I started making knives many years ago, I had a set of files, a Chinese made 5 inch vise, a hand drill, bunch of sand paper, lots of sweat.

I am not going to say that anybody famous has one of my knives, but a few firefighters do carry them as crash knives. I spend 50 to 70 percent of my time making knives. The rest is for other things.. If you want a knife, I can make it, if want order one I can make, if you want to trade stuff for one, I can do that, if you want to trade for the right materials I can do that.

I come from a different background, I am a knifemaker and a blacksmith. I use a 2 x 72 belt grinder, which is common in the knife trade. Which I built both of the ones I have. I just got my little lathe and done some neat things with it, but what I did was a refinement of things I have done in the past. I also own a mill/drill and have made jewelry, remade tools, found out what not to do with some bits. I have to order some of the accessory items for my little lathe, because some of the things I want to do, needs another chuck or a third hand type device. Oh, and congratulations on taking the plunge, it took me a while also. Jerry At 05:16 AM 11/28/2002 +0000, you wrote:

Even if you decide later that you did not make the "right" choice. You'll have learned enough about these smaller lathes to know what to look for later. Many owners add lathes to their shop, I'm one. It allows leaving complex setups on one while having the other(s) for one-up projects. Also, if you ever get into toolpost grinding, you can do that on the most expendable lathe. The abrasive residue is not kind to a lathe's mating surfaces.

for $299 since I am to poor to afford anything better, I barely scrounged up enough. lol its my only christmas present and I had to pay half. Oh well, hope I made the right choice... I alreayd have some toolbits and measuring equiptment that I use currently so the bugg has Officially bit me.... did I make the right choice? BTW, during my senior year in on of my machining classes my teacher and a few other advanced students began building a tom thumb type engine, it didn't really have a name. Some guy designed it, we modified it to make it better but it has yet to be finished due to time contraints, although most everything important is done, gas tank, carb, and small stuff is all that is left. We also cut out own gears which was a learning experience. Well sorry I wrote so much :) I will get pics up when its finished, who knows how long... |
Re: Lathe Accuracy
Good Afternoon, Bob:
The taper is smaller toward the headstock. The lathe is not bolted down, but is sitting on a 1 1/2" workbench that is level. Am wondering if bolting the bed down will correct this tapering situation. I have cut several 1/2" steel rods; with the tailstock locked down, and unlocked, with the same results. I am considering trying to test the alignment of the head/tail assemblies using centers and a DTI. I certainly appreciate your time, and will advise of my findings shortly. Best regards, Nick Bob Sunley <rosunley@...> wrote:Nick, which way is it tapered, small end to the headstock or tailstock? If your lathe is bolted down that can twist the bed and swpping parts will not help. Try loosening the bolts holding down the tailstock end and take another cut. If it changes the bed was twisted by the bolts. Then you shim it so when it is tightened down the cuts are true without a taper. Bob On 27 Nov 2002, at 15:23, ntdefeo wrote: Good Morning: Yahoo!
