A few hints on paint stripping and re-painting machine tool parts. These are typically cast iron items with natural surface roughness. Consequently they are not worked all the same as in a typical car body paint job. Also I comment on the consumables I use, like paint cups, abrasives, etc.
Products used in the video:
Fill primer: Autocolor AP-Merit 7520 HS 2-component (with brush: no thinner; with spray gun: thinner added)
Abrasive: 3M Xtract 710W, 240 grit and 320 grit, 150mm dia. pads
Cups: SATA RPS 0.3 liter
Spray gun: SATA MiniJet with 1.0mm nozzle
Paint: Spies Hecker Permasolid 275, color code RAL 7012 basalt grey
00:12 Intro
03:57 Paint stripping
06:49 Cleaning the casting
08:24 1st Masking

Excellent paintjob, looks -as you say- factory or better than factory. Appreciate the tips on masking a lot. I didnt expect that you do so much work to the casting itself, but it makes sense. Thank you!

The moral of this video: There are no shortcuts to an excellent result

Good to hear from you again, I value your content. Please don't be a stranger to RU-vid, the time and effort you invest in sharing you knowledge is a benefit to us all.

@keithgarland3404 Год назад

The thing is, after you have been taught general engineering principles, and gained hand's on experience over many years, you know what is top quality work, and what is slap dash or bodge work. Your work is always top quality, thank you for sharing your skills.

@sarahdelacruz5208 Год назад

What a great video. Another reason to repaint stuff is…. “I like to have nice stuff” it may work fine, but its also nice that it looks good.

@Gottenhimfella 11 месяцев назад

Yes. For some reason, everyone understands that cars (and their owners) benefit from perfect paint jobs, but they don't extend that to machine tools.

@NS-no1li 7 месяцев назад

Forth one that is very important … having pride in your work. That makes a craftsman. As you said.. people notice that..

@billdoodson4232 Год назад

Love it, "I'm starting the sanding process with 240 grit". Most people I know would consider that the finish sanding process. But the end results speak for themselves, those tables look much better than new.

@AlmostMachining Год назад

This is an amazing video Alex! I am a firm believer in good paint so much so that i have a few years of projects waiting on paint. I really like your approach to this and the reasonings behind it. Thank you !

Do you do your way scraping before paint or paint and then scrape the ways? It is a bit insane to paint a tool to that standard but it’s your tool, your time, your money so you get to do it your way. And they look awesome and I’m sure the haters are secretly jealous. Thanks for providing paint data in the video description! Love your work Alex, wish you did more but it’s obvious that months of work go into each one.

Oh yeah, another newbie tip - grey primer then top coating with grey can be confusing for gauging coverage. Try using black primer. It's easier to see when you have good coverage.

Funny store I bought a old craftsman lathe used it for 15 years came across a big better lathe. So I decided to clean up the craftsman to sell it and sprayed it down with degreaser and pressure washed it and all the krylon rebuild that was on it came off leaving perfectly preserved factory paint. Sold it for $350 more than I payed for it.

@darrenfloen2693 Год назад

Awesome video. You make a lot of great points about the details of the prep work. As a fellow V13 owner, I think you should do an indepth video on it. Your likes, and dislikes. There's not a lot of info out there on how great they really are!

@johnhall8455 Год назад

Excellent video, BUT…the first thing I noticed was the absence of a face mask when paint stripping/chipping/sanding….even though you can’t see it when chipping, fine dust particles are still created, and old paints often were lead based….HIGHLY TOXIC…..STAY SAFE..👍 I always use an etch primer first…good adhesion to the metal, and to subsequent coats…

@ikkiiiieee Месяц назад

You might want to know that brake cleaner is good for the initial clean, but not before paint. You should use a final wipe of something like acetone, alcohol 99%+, ... Because brakecleaner contains a minute amount of acid (I think is the cause if I remember) which could lead to imperfections like bubbles, adherence issues, ... I recently repainted my machine and did loads of research before hand. I also have experienced the issues I read about when I did another machine years ago. Though take this with a grain of salt; i am merely a perfectionist amateur with an internet connection

@DAKOTANSHELBY 9 месяцев назад

I've watched this video quite some time ago and just again today. I'm acquiring older machining equipment of various paint colors. My plan is to apply the same techniques as you displayed on all my machinery, but also choose an appropriate common finish color for all the machines, as I want a common color scheme in my home shop. Your technique to strip and repaint will be applied, but I'm still struggling to select a final color for all. I am leaning to an off white, but certainly want to avoid the traditional dark Grey. Any suggestions are welcomed. Thank you.

Wonderful video. If you were to repaint an entire large machine tool, would you still use a scraper or use another tool when working far from precision surfaces?

@iamthebiker Год назад

Yes

@car9167 Год назад

stripping chemical gel makes miracles. I repainted from the bare metal a 1954 surface grinder. On the column I had to apply the gel 4 times to strip so many layers and filler. Way less work than your way.

@dennisa6132 Год назад

For stripping using chemicals, lye is very cheap and does not hurt cast iron. I used an immersion heater, a container and I could strip entire parts, such as the ribbed underside of my milling table very quickly. Working with lye requires safety equipment, gloves and eye protection!! You know you are dealing with lye if your fingers get the lye solution on them and they feel slippery, that's the oil in your skin being saponified.

@wibblywobblyidiotvision Год назад

Excellent video, as usual. Quick question - where do you get your scraper blades? I have a bunch of hand scraping to do and I'm getting a bit fed up with resharpening HSS, I think it's time I made up a new scraper with a carbide blade.

@anengineersfindings Год назад

This answer may not be helpful, but it is what it is: I got a handful of flat pieces of carbide years ago from a friend who worked at a carbide manufacturer. These blanks may outlast my lifetime. Only thing I had to do was to grind the cutting edge shape/radius. ATB, Alex

@wibblywobblyidiotvision Год назад

@@anengineersfindings Thanks, Alex. My original plan was to use a busted carbide slitting saw I have lying about, I think that's what I'll end up doing unless I find a real score on some "proper" scraper blades.

@DrFiero Год назад

If anyone else is doing this - and you find you're get brush strokes in the surface after it's cured, add about 10-15% {appropriate to your product} reducer/thinner. The 'slow' version preferably unless you're getting runs in the finish (then go up to medium or fast). This will allow the product to flow out more and become level. Working on a surface that's about 20* C helps flow out as well.

When you talkd of "silicone cleaner", I'm guessing you mean something like Mipa Silikonentferner (Silicone remover)? Is that because it has good cleaning properties, even when there is no silicone product to remove?

@anengineersfindings 11 месяцев назад

Good point! The term "silicone cleaner" (as used by painters) refers to a very clean and mild type of solvent that is used to degrease the surfaces to be painted. There are several types on the market, from ethanol-water mix to the more common pure hydrocarbon types. Actually I cannot tell you why this particular term is commonly used, the process has not much to do with silicone.

@billdoodson4232 11 месяцев назад

Alex, where can I get a carbide hand scraper from? They are like unicorn horns here in the UK, I have been looking on and off for the better part of 2 years and a ground down file really does not cut that well. Thanks.

@anengineersfindings 11 месяцев назад

Hello Mr. Doodson, I just checked if I had a spare blade to give to you. Unfortunately I have only one spare left of the handful that a friend gave me about ten years ago. So I'm having a hard time parting with this last one, I hope you can understand. However, I do know that the German brand Rennsteig sells carbide scraper blades, maybe you can find a source for that in the UK. ATB, Alex

You need to be careful, older machines were painted with lead based paint (at least in the United States). Stripping or scraping old paint could lead to lead exposure and lead poising
