I was cutting an iron L rod, and the cutting disk began to produce red sparks, instead of these habitual bright orange. Simultaneously, its cutting effectiveness was down dramatically. I searched in the web, and learned that this phenomen is named crystallization,and it is due to overheating. Now, my disk is a new one, I want not throw it to the waste. Any idea how to get it back?

How can I sand stainless steel down to a flawless mirror finish? What is the best way? What tools should I use? Answered

I have a stainless steel filing cabinet painted khaki. I want to remove the paint and give the underlying steel a mirror finish. Removing the paint is not a problem. The problem is I don't know how to give it a mirror finish. The finish I want is so that I would be able to see my reflection just as if I were looking in a normal mirror. Here's an example of what I'm trying to achieve, starting from an old, painted filing cabinet. If I could make it look that good or better, I'd be satisfied. I have tried several methods which I found on the internet but none of them seem to be working. I have tried sanding by hand starting at 60 grit and going up to 220 with regular sandpaper. I have also tried using emory sandpaper which says it is for metal. I used coarse up to fine. Neither of these are resulting in a mirror finish. With the regular sandpaper, after using the 220, I can sort of see my face if I get really close and look at it from exactly the right angle, but can't make out any features. I also tried using various dremel tools attached to my electric drill. These give a much different finish than what I am trying to achieve. It ends up looking like brushed aluminum. You can't see a reflection in this because it's too diffused. Then I tried using a sandpaper wheel attached to my angle grinder. The sandpaper wheel was made up of many sheets of sandpaper, shaped into a wheel. It sort of worked, but was very uneven. I could see my reflection in little parts but most of the rest of it was scratched up.Then I tried using a belt sander, using paper from 50 up to 120. The result was similar to a stainless steel refrigerator, but messier. There were a lot of lines or grooves, and they were not straight. So the best I have achieved so far is a finish close to that of a new stainless steel refrigerator or stove, where you can't see your reflection, but the sanding grooves are clean and straight. I got this through a combination of the angle grinder, the belt sander, and hand sanding from 60 to 220. I also tried a small section purely by hand, using regular sandpaper from 60 to 150 and got slightly better results - meaning there are fewer lines. But the reflection is still barely visible; it's still way too cloudy. These results could look nice but they're not what I want. I'm really trying to get the perfect mirror finish. I've tried to upload pictures of what I've got so far. Don't know if they will make it into this question or not.

Update on the layered metal weapons/props

Hello to everyone who took the time to read this update/list. So I have not forgotten about my promise to upload the Solidworks files and cutting plans. However that will be taking a backseat to finals until summer break. I will however go ahead and list off the items finished, in progress, on hold, or currently only in Solidworks form. Finished -6in Axe: 3lb head on an oak clad 1/4in steel flat bar about 20in long total -3in Tomahawk/Axe: 1.25lb head on a para cord wrapped 1/4in steel flat bar about 20in long total -27in BoneSplitter: 3.2lb aluminium reinforced steel construction. -18in BoneCracker: 2lb aluminium reinforced steel construction. -18in All steel BoneCracker: 3.5lb steel reinforced steel construction. More square handle and better center of balance than previous version In progress -10in Bearded Axe: 3.25lb head. To be mounted on oak clad 1/4in steel flat bar handles 18in, and 30in long. -10in blade Pugio: Model made of mild steel for practice and training. Needs to have bevels, and fullers ground plus handle and guard mounted. -8in blade Pugio: Model made of mild steel for practice and training. Needs to have concave edges, bevels, and fullers ground plus and guard mounted. On hold -14in Blade tester: Simple test bed modeled after BoneSplitter to test viability of various band saw blades(Metal and Wood cutting) for use as cutting edge for mild steel blade carriers. On hold due to the band saw blades being too hard to drill through. Only existing as Solidworks files --27in Revised BoneSplitter: 4.5lb Aluminium reinforced steel construction. Better center of mass and more square handle than MY           previous version. --37in blade Bastard sword: Aluminium reinforced steel construction. Should be very close in terms of center of balance and stiffness when compared to its hardened steel companions.  --20in blade Stacked steel Gladius: Twin riveted steel support plates with detoothed metal cutting bands saw blade used for striking edges.  --blade Hispaniensis Gladius: Single piece of metal for the blade. --blade Cinquedea: Single piece of metal for blade. Multi fuller blade. --8in blade Pugio curved: Same as other 8in Pugio except for the convex curved dagger tip --14in blade Spear from Fullmetal Alchemist: May upload the variant of this in which the "wings" are separate pieces of metal. --3.25in square Warhammer: 8.5lb head Assembled from 13 1/4in steel plates pinned together. Front is covered in 3/8in spikes poking through a steel striking face to prevent separation of the plates. Back end is a 4in spike. --5.25 square Warhammer: 16.25lb head Assembled from 21 1/4in steel plates pinned together. Front is covered in 3/8in spikes poking through a steel striking face to prevent separation of the plates. Back end is a 4in spike. --Straight edged War Axe: 7lb head Inspired by Ironclad Industries' Riftclaw. Made from 7 1/4in steel plates pinned together. I am aware that the riveted and pinned construction of these items makes them inherently less durable and less corrosion resistant than single piece construction. However I am a college student who is working with mostly scraps and whatever has to be purchased. Since mild steel thick enough to carve the Warhammers or War Axe is not common scrap material around the college's machine shop the only way to economically create them is to use stacked plate construction. As for the BoneSplitter, BoneCracker, and Bastard sword the stacked plate construction is used to both reduce the weight of the item and stiffen it at the same time.

Softening Candle Wax (lost wax casting)

Well, I made my first lost wax casting yesterday using lead, and a Plaster of Paris mold. It worked great, except that I didn't have enough lead. But, after searching on the great web, I realized that the wax I used was much harder than what the sculptors use. Why is this? Is it a different type of wax? I searched Google, and couldn't find anywhere to get the wax I needed. Maybe I typed in the wrong name. I don't know. I'd much rather use my own wax, as my mom has a stockpile of large-er sized candles that softened and deformed in the Florida sun. How would I soften it, other than heating it in water? Is that water method thing how they normally do it? I'm really into melting metal, and want to do more casting, so can someone help?

Nonleathalbychoice style weapons/"props"

Hello to anyone who follows me. Yes I am still alive. Now the reason I am posting this is because I feel like I need to give back to the community I have been using/involved with for years now. Not the craft community but the Knex community here. Many of them have moved on from Knex since starting college and so have I. Mostly do to the lack of space and already messy room. So in order to give back I have come up with a better more interesting method. Instead of using Oblivitus's method of making the Knex guns in a CAD program I will instead be giving you the plans and basic instructions to make weapons/props inspired by Nonleathalbychoice.  This being said unlike the Knex guns these items are going to be less accessible, more difficult, and dangerous. To do these things it will help to have a computer with Solidworks 2014 on it. Later I will post PDFs of the cutting plans in order to reach a wider audience. That being said  some of the projects were  and will be inspired by scrap metal I found and will be costly and wasteful to replicate. However I believe that the raw materials for 4 of the projects came in at under $100 total. So still cheaper than many of the larger Knex guns. Also I probably wont be posting these things as step by step instructions since most of these items are made by just cutting out sheet/bar metal. Any advanced instructions will be noted. The time frame for these instructions is going to be very slow due to college. Expect maybe 1  a month if even that.  I will try to inform you of changes and fixes as soon as they become apparent to me.  Also I am first writing this after only an hour of sleep. So if any of you spot grammatical errors please point them out to me.

Cheap Source Of Propane?

When I got a new can of propane, for my torch, it was $9. At wally world, it was $4. Then, when I went to get a can of cooking stove propane from the camping department (at wal-mart), I notice that the tank was $3. After getting home, I noticed that the threads were exactly the same, and that the torch head would screw onto the neck of the "camp propane" bottle. So, as anyone would do, I fired it up, and it worked! Of course, it would shut off it you tilted it too far, but what the heck! $3 for a can of propane. But then I thought "Why is this so cheap, and why haven't I heard of this before? Is ther something wrong with this? Will I blow myself up?!?!?! Anyway, I'm all for saving $2, or $6 (depending on where I go), so is this actually a reasonable way of saving money?So what I'm asking:-Is this way safe? I haven't fired it up since, in case it did something bad.-Why is it so cheap to but it that way, and so expensive to buy regular tanks?-Has anyone else done this?If anyone can help, it'd be appreciated.

Spanish or French | Intro to Metalworking or Intro to Engineering and Tech.?

Ok, so it's that time of the year - picking 9th grade courses. I'm signing up for all gifted (higher than honors) academic classes, but am stuck on my electives.To get into universities and colleges in Georgia, I have to take 2 sequential years of either French or Spanish. My mom says Spanish is easier, like I'm sure most people would. I don't really care about speaking fluently in either language; I just need to go to college.What would you say would be the easiest to get through?So, I guess all of y'all know that I aspire to go into the mechanical engineering field. High school is a good place to start out, but I've come upon another bump in the road: Should I go with the metalworking classes, or the engineering (and technology) ones?I've always wanted to be able to weld, and I'm sure that's a major skill when it comes to engineering. Classes that my future school offers include Intro to Metalworking, Arc Welding, GMAW and GTAW (which I won't take), Intro to Milling (which includes using a lathe and a CNC machine), and a sheet metal class. The engineering class covers things like CAD, CAM, CNC, robotics, audio and visual productions, and other technology things.I think the metalworking would be best for me - I'm more of a hands-on person; i.e., I like tangent things, not doing "theoretical" things on a computer, though I know all of the CAD stuff would be very useful.I'd like to take all of it if I could, but that's only possible by going to summer school (which costs $180 per class).Any help would be appreciated!

Building a Foundry?

So I've been experimenting with building a mini foundry made out of steel cans. I've experimented with several different fuels, fuel injection systems, oxygen injection systems, crucibles, and different metals. However, the only metal I've ever been able to melt with it is zinc. (if you don't know, zinc doesn't take alot to melt; only about 700F) My target metals are aluminum and copper, but despite over a year of experimenting, I've never been able to melt either. I would like to know what I'm doing wrong, or what I could do better. Here's the rundown of the furnace's construction: The fuel I'm currently using is propane. The foundry isn't big, (you could fit it in a backpack) so I just use propane canisters for torches with a normal output line on the end. The line runs to a small piece of glass laboratory tubing with a tiny nozzle on the end which is about 1 mm in diameter. The propane shoots out as a stream and mixes with air utilizing the venturi effect. The propane mix then shoots into a large metal pipe about 2 cm in diameter. It then bends up at a 90 degree angle and enters the furnace, which is in essence, a steel can with a hole in the bottom. inside this is a steel can cut in half with a thick wire through it to suspend it above the burner.  So what could be improved? When I run it at full blast, the whole furnace glows orange, but no metal melting happens...

Metalwork: How to solder a joint close to an existing joint without melting the first one? Answered

I'm trying to make a sculpture by soldering copper/brass rods together, but when I try to make one joint, it melts all the surrounding joints. I tried putting on some heatsink tweezers but they weren't effective. It's going to be quite complex, so clamping the whole thing and soldering all the joints at once won't be practical. Any tips for making a better heatsink? Should I just solder faster? At the moment I'm letting the metal get really really hot because I guessed it would make a better joint, but maybe I'm overdoing it?

I need some soldering advice from you guys

Hello Everyone - I am trying to solder a different type of a joint, and I'm having a problem doing it. I am hoping someone here can tell me what I'm doing wrong (or not doing). Here is my problem:I am trying to solder an alligator clip to a 3/16" dia steel rod (I have a picture of this joint, but for some reason, I can't upload it).When I heat up the joint with my propane torch, the alligator clip goes red hot first, and the rod takes a while longer. The rod turns a really dull red, but never as hot as the alligator clip, because the clip is only ~ 0.020" thick. I have a roll of silver bearing resin core solder that I am using. When I apply the solder, it just sorta balls up and won't flow over the metal at all. I end up with a bunch of melted balls of solder on my table, and that's it. I didn't try using any flux, because this solder is resin core. Is there an inexpensive way of doing this ? Does anyone here know a method that works ? thanks in advance, Terry

Low friction "bearings"

For several of my projects I required some sort of bearing that would not only allow for a minimised free play but also very low friction.Before you get too exited: This is not a new type of bearing or anthing for heavy duty loads, not even for ongoing use without servicing.I found that even slightly heavier things rotated on makishift bearing far easier if the axle was verticall instead of horizontally.This gave me the idea to try a simple needle-bearing approach.This is how it goes:1. Grind and polish your axle to get a nice needle point - it must be perfectly centered!I prefer to do this with the axle in a fast spinning drill on a fine grinder.The polishing in a simlilar way, but please do not try it with a cloth in your hand on a spinning axle!2. The other part of the bearing is a screw or pin with a punch mark.I grinded and polished a punch for this so it has an angle of 60° and polished it to a mirror finnish.If alignment is of importance then of course the pin/screw must work for this purpose!If in doubt make it spind an use a pencil to get the true center.A drop of sewing machine oil and it spins nice and with very little friction.The key is to adjust the gap(s) between axle and punch mark to next to nothing.You don't want any pressure along the axle as you would "drill" a hole into your mounts.And you don't want it too loose to avoid wobble.I hope it might give you an idea for your next project.

Project suggestions for the summer holidays; lots of time, not a lot of money?

I have a reasonable variety of woodworking tools, metalworking tools including a lathe. I'm 18 and consider myself pretty good at practical things, I'm looking for something labour-intensive that doesn't cost very much and I'd like to have something interesting at the end of it. Any ideas are welcome :)
