Guitar Finish? Answered

Hello, I am finishing my electric guitar, and i wet sanded and everything, and i heard rumors that you use rubbing compound on the last bit to get it to look good. In the instructable by Gmoon, applying a mirror finish (by hand), it says that he used Rubbing compound, but people keep saying, "I think you mean POLISHING compound....", and i don't know which one to use. I have the guitar all dull looking from wet sanding, and i just need it shiny. What is your outlook on this? Thank you

Lacquer or Varnish to finish a guitar?

Hi, I've just had an artist do some work on one of my acoustic guitars. Its done straight onto the sanded bare wood using sharpie, all I have to do is give it a finish to stop the design getting damaged and to give it a glossy shine. A lot of people recommend Lacquer but what type should I use? Nitrocellulose? Poly? Others say Varnish but I've heard it can become tarnished from sweat and heat. This coat needs to stay on indefinitely as I cant sand it down again to apply a new coat without removing the art. Please help!

POLL Which gun to finish first

Hi, I am making my 2 first guns at the same time, they are of different types. the first one is your run of the mill sniper with the bolt action, modded sprinkler and barrel LEDs, this one shoots big marbles and the traditional potato. the second one is not as constructed as I started it when I got tired of making the first one ( I swap between them depending on which one i feel like making) anyway it shoots the small type of marbles, but this one uses a hammer valve Which I'll try to explain now, the cylinder is pressurised to about 100 psi, the hammer is drawn forward which pulls the whole barrel forward, this is then caught on a sear trigger, when the trigger is pulled the barrel is pulled back by rubber bands and hits the hammer valve, this opens the seal allowing air to escape, then once the projectile has been fired a spring pushes the valve closed, blocking the air, there is an animation that helps exlain it down the bottom (it isn't mine but works on the same principle) also I am not going to make a magazine for it as I cant find a way to make sure only 1 marble falls into the barrelP.S if you find anything wrong with my designs tell me as I am only 13 and these are my first gunsP.P.S I will only be able to post around new year as I am busy with exams and the suchP.P.P.S If i am to make the hammer valve gun first it will take longer because I am not as far advanced in itthanks for reading be sure to check my topics on some of the aspects of the designs:optimisation of pneumaticsbest chamber to barrel ratio

Tips for finishing cut bottles

I bought my boyfriend a Kinkajou Bottle Cutter and Bottle Cutting Inc. sandpaper kit because he was interested in recycling bottles into drinking glasses, candles, etc. He was really excited about the handmade gifts he planned to make, but the sanding/ finishing of the bottle rim has turned out to be such a laborious process he's only finished one glass in 6 months. The sanding papers range from 80grit to 220, I believe. It just takes so long to get a nice smooth edge that your arm is killing you and it's difficult not to give up before achieving a truly professional result. Anyone out there have tips or tricks to make the finishing process faster or less tiresome? Any secret tools of the trade we should know about?  We don't have a garage or big power tools to work with, though I've considered seeing if maybe there's something we could rent for a day(?) I've also looked into BC inch's new "diamond' sanding pads but we're hesitant to drop more money into the project unless we hear those are totally amazing. I welcome your thoughts!

So I am pleased to up the stakes.Free Patch for every submissionThe screenshots have to be different to last monthsThey have to have a description of whats going on (geektool, objectdock, etc)They have to be listed as a new comment below!To take a picture of your desktop on a windows machine use the printscreen key on your keyboard, Open up paint, Edit, Paste and then save this as a png. then upload this onto Instructables.To take a screenshot on a mac use the apple key, Shift and 3. This will save the picture to your desktop then you can upload it to Instructables.To take a screenshot in Linux go to Applications>Accessories>Take screenshot. If this doesn't work blame Lithium Rain ;-)I have a nice new set of wallpapers this month.My main screen is running a Leopard Vector reboot wallpaper, I also have the following running..Geektool, in a range of Helvetica NeueTinkertool, which is keeping my dock in a different style, and puts the eject button in the menubar.My second screen is running a favourite wallpaper of mine, one that I rejigged to fit portrait.Finally, my third screen is running a picture of me and my Fiance Hannah from when we were in Durham.I have added an extra picture of my current screen set up, so you can make more sense of my screenshots!So, get your Desktops and wallpaper screenshotted and sorted, and collect your Patch!

Lexan one way mirror/visor

Hello I recently bought some lexan sheets and was thinking about making a visor out of it, given it sturdiness. For a nice finish i would like to make it like a space visor, a golden-chrome one way mirror. I have already tought about the molding process but the one way mirror finish is more difficult than I expected: can you give me some hints? Also, I thought of three ways to get the results I want an would appreciate your opinion on them: - Car adhesive mirror finish (but I don't know if it will take on the lexan) - Spray paint, golden chrome (a thin coat should let through enough like to make it usable) - Golden plating via electrolysis and conductive paint (last hope, this requires expensive and poisonous chemicals) With my most sincere thanks

Just one to go... (Update...Just!)

A few people have taken the time to mention that I am approaching my century - almost 100 Instructables. OK, so plenty of people have gotten there before me, but this is my first hundred on the horizon. I have now published #99, and I know what #100 will be. Looking ahead, though, what will your hundredth project be? UPDATE: #100 nearly didn't happen, as I came off the road on the way to the site.  Fortunately, the people I was going to meet came to meet me part way and helped pull the Mini out of the field.  The Mini is now awaiting diagnosis at the garage, which will certainly involve the words "bent" and "steering". Anyhoo, I got what I needed, now just putting together some more research notes with the photos, then get it checked by an expert... UPDATE TO THE ORIGINAL UPDATE: #100 is, effectively, done.  I'm just waiting for the expert who helped me to give it a once-over to check I've got my facts straight.  Since I've been using her work email address, I expect to here sometime Monday... UPDATED UPDATE: Ow!  My shoulders, neck and back are ceasing up, typing is getting painful (something to do with dropping three feet at fifty and coming to a dead stop in the field...). But, the garage where I dropped Womble off has just phoned to say they can't find anything obviously wrong (or bent) with the car that would explain why the front wheels are pointing in different directions.  They theorise that the impact bounced things a notch or three along without actually damaging anything. But, they also recommend taking it to a specialist bodyshop to get it checked... PROBABLY-FINAL UPDATE: And now I have Womble back - all that was needed, after all that fuss, was a slight adjustment of the tracking.  Now that is engineering. ON-TOPIC UPDATE: #99 is now finished off with photos of the piñata in action.

I realise this putting together a Scorpion model project is old, and still not finished but....?

The project is something I will be doing with a young AS person this weekend.  It is not a super simple model, but it does only have about 12 parts to it.  I also, later on, want to modify it a little, so I was going to document that portion for sure. But would it be interesting enough to include pictures of me and the others putting it together?   I would LOVE to be able to take some video too, but alas, I don't think my current equipment will handle the audio portion, which is going to be the best part.  I know, I know, you will come back with Kiteman's law......but really, this isn't a "build"  as in make from scratch, it is a simple "make from a $9 model" project (originally priced at $24.99 at Discovery Store).   Let me know, AND ALSO if you have any ideas on how to make it more awesome (I will be fitting it with UV LEDs later on, since the skin it transparent....and if I can find a small motor, maybe even actuating the one movable claw :-) ).  REVISED:  Sadly, I have been informed that the youngin's are down and out with a cold that may last into the weekend.   SO, that delays my project for one more week.   But THIS ONE, I am definitely finishing.  :-)   I still haven't FULLY finished the project, but I have added some pictures.

have i got 1 good driver or 3 bad ones

Hi all, nice to be here I have just finished building my first cnc router and about to start actually doing something with it, during my build I somehow managed to blow up 2 grbl boards and 6 drivers, hey note to myself, don't connect voltages when tired late at night also I have a problem, I think, thanks to YouTube I found how to set the voltage using the trimmer pots on the driver boards, I set all 4 drivers initially to 0.75 volt and it all works and tests fine, apart from having to buy 2 more driver boards when the trim pots fell off that is apart from one of the stepper drivers powers one motor (Y axis) and when it finishes working it goes absolutely solid locked up and sounds like it is groaning, the other 3 are firm but not locked up I tried increasing the voltage on the 3 looser stepper motors to 1.0 volt and it didn't seem to make a lot of difference, but to get the solid stepper driver down to the same stiffness I have had to drop the voltage down to 0.4 volt and it did stop groaning and loosened a bit I swapped over the motors, same result, moved the driver to another spot on the grbl board exactly the same effect on a different motor, so it looks to me like it is the DRV8825 driver board is this a case of I have 1 bad board and 3 good boards? or 1 good board and 3 bad boards ? any help would be more than welcome info on my cnc build and components below basically the cnc has a bed of 900mm x 900mm and is pure self build made up of parts found laying around my workshop, rails bearings lead screws etc, and I added in a new Arduino uno (of which I am novice) and a new GRBL board and ended up using DRV8825 drivers, stepper motors are used (eBay) 4 x identical minebea 23LM-C343-14V wired from 6 wire down to 4 wire with pairs being red & yellow and pair 2 being blue & orange, which I believe is correct LINK TO STEPPER MOTOR SPEC SHEET please correct me if I have made a mistake I have used links to set all drivers to 1/32 micro stepping, also set the mm rate so it is exact at 500mm travel, and set max speed at a sensible 400mm per minute as I am not really expecting supersonic speed and all is nice and quiet, nothing straining I have paired 2 of the stepper motors via the grbl to drive the X axis and used the clone spare on the GRBL to make that work, which it does marvellous The CNC structure does need strengthening up as mostly built on ply at the moment, but everything works as expected, the spindle is a nice almost new RotaZip high speed tool that I bought new about 4 years ago and only used it on one job so keeping stuff does come in handy even if wifey says it doesn't Look forward to sharing info on here as I learn more

Aging/antiquing black metal

This is kind of an odd one. I'm using a firearm for a movie firing blanks. Currently, it looks like this. http://www.valorcorp.com/images/products/1012048A.jpg I'd like it to look like this, mainly so that the camera can pick it up better, as a solid black finish won't register as well, and all the tiny inperfections will make it look more interesting. http://www.gunblast.com/images/SHOT2009/Day2/DSC05076.JPG It's the exact same gun, but some come "reliced" and others don't. I got a good deal on one that wasn't. I don't want to mess it up too bad, no big pitting or scratch spots, just rough the finish up a bit. Any ideas?

How can i make the code for an excel macro be universal and not only work for one file?

So i am writing a macro to graph a large set of data. After finishing writing the macro it worked fine on its original fie in this case 234 here is one of the original sets of key data. ActiveChart.SeriesCollection(1).XValues = "='234'!$A$27:$A$1490" It specifies the 234 as the file to retrieve the data. I assumed that after replacing the 234 in the line of code above with a command like sheetname. like so below. ActiveChart.SeriesCollection(1).XValues = "='sheetname'!$A$27:$A$1490" Who ever can successfully answer will receive a patch. Feel free to ask questions because what i wrote above is a slight bit vauge.

Next week: 5 Instructables in 5 days

I have a backlog of Instructables that I need to clear out of my office and my brain. All of which are only an hour or two away from completion, not including the write-up. One has been waiting to be completed for over a year now and all it needs is a little tape and hot glue! It's reached the tipping point. No, that already tipped and fell all over me and I've been pretending not to notice as I wade to and from my office chair. My self-imposed deadline is for next week. My goal is to publish one a day Monday through Friday. I figure that that will make me finish them once and for all and get started on the next batch of projects that I've been meaning to do. The list is getting long. So... who's with me? Anyone else have some projects that are thisclose to being finished? You don't need to do one each day, but maybe just one or two.
