Great videos! I noticed you were having difficulty drilling the plastic nozzle without the drill bit digging in. IFor drilling nonferrous material, you need a neutral cutting angle on your drill bit. I modify a set of drill bits for nonferrous materials because I do a lot of work with plastics. It can easily be achieved by using a diamond hone to file the end of the drill bit holding the hone in plane with the axis of the drill bit and just taking a bit of material off. You will be amazed by how easy drilling plastic (and aluminum) once you have a cutting face that is perpendicular to the material being cut. It just doesnt grab.
Ok. Thanks. So you want neutral rake angle. Where normal bits have a positive rake angle. Link to a diagram for drill bit geometry. en.wikipedia.org/wiki/Rake_angle#/media/File:Metal_Cut_diag.svg
This was a very helpful video in getting our powder coating gun to produce a better spray. Thank you so much for making it and we will be subscribing to your channel for more helpful advice.
Thank you for the valuable information. I have a question please. Is the dual voltage from Eastwood better of the redline ez 50 or redline ez 100? Please help me. Thank you in advance
ok your smart about this stuff. i just got a new gun with KV and Au. I dont understand the difference between & what each do to use them correctly in different situations.
Great shirts and even better fixes. Also good explanations. What kit on ebay were you talking off (i may get it and let you know if its a scam). I'm more interested in a build myself
$1000 is allot for a pro setup, i only need to powdercoat the occasional rim and such. i think id stick with the eastwood gun and the simple mod, but would be intrested in how much the kit improves it as well
Great video, as always. The sound effects really tie it together. :D I'd be more interested in seeing a kit being put together, personally, but I'm sure I'd enjoy whatever you end up deciding to do. If you do go the kit route, do you plan to incorporate the Eastwood bottles?
Thanks. I wouldn't incorporate the eastwood bottles directly. But with not only that kit, but most powder coating guns, the powder hopper/reservoir are not directly tied to the gun. So you can use whatever size/shaped bottle you would like. Including the eastwood bottles. The down side with them though is that they are really small. :)
In this powder coating gun, no. Just an electrode. It would be fairly easy to make. Something I would like to attempt. This video was more or less seeing where eastwood failed miserably on there design. And my hopes was to give simple modifications that people could easily perform.
Josh, saw your comment about modding a HF gun. Not sure if you have one already or not, but I just upgraded to the DV Eastwood setup and would be willing to ship my old HF one to you so you can do your magic for the viewers. I thought this was a very well done vid and look forward to more. I hit the subscribe button so I can stay tuned.
Thanks you. I do have one though. I just finished testing it for a review. Not sure what I can do with it to upgrade it. I have to think about it. There is a definite packing issue inside the hopper. It may be due to the hopper's shape. If I may ask, what do you think of the eastwood gun vs the HF gun?
I plan on using the Eastwood gun sometime this next week for some motorcycle parts. I just drilled the holes in the tube yesterday to improve the pickup. Also, on the Eastwood gun; I noticed the hopper connection was very flimsy. For the HF setup, it will get the item coated. I often had to shake the hell out of it to get the powder to come out and then their would be cloud bursts. I probably waisted a lot of powder. I think my other issue is with my homemade oven right now which I hope to resolve over this next week. It wasn’t getting up to 400 degrees and I was getting some dimples and some orange peel occasionally. I have personally never used an expensive setup, so I have nothing to compare either setup to. As with everyone else though, the foot pedal on the HF gun is pretty legit and I think it’s a good gateway gun for people because if they don’t like powder coating then they are only out $60 and if they do then it gives them a baseline to go off of.
Thanks for your reply. You pretty much confirmed how I felt about it. You can get it to work, but it's not great. Since I didn't use the HF syestem as much as eastwood's, it's nice to get a second opinion on it. Oil contamination, I think can also generate dimples, but yea. You need the part to get to 400F. If you still have problems after you fix it, try a prebake. Yes, the hopper on eastwood's gun is a bit flimsy. But if it ever breaks, just glue on a new lid. It's all they did. :) If the push button ever gets old, you can pick up a nice foot switch on amazon for $15. It's hefty. So it wont want to walk as bad as the one on the HF system. amazon.com/Heavy-Duty-Industrial-Foot-Switch/dp/B01D5BYN30
If your talking about the stock diffuser, yes. It's pretty much useless and had to come off for the new tip I installed. If your referring to the new tip, no. That diffuser works very well. A defuser is necessary for a powder coating gun. It not only helps to keep the electrode clean, but I believe it creates an ion cloud, so to speak, that better transfers the electricity to the powder. It's just that the one eastwood designed is so terrible, that your better off without it.
Josh, great video! You put lots of detail and thoughtful analysis into what you do, and as an engineer I can very much appreciate that. Would you be willing, on behalf of others looking for a dirt cheap powder gun, to look at the harbor freight system? I've seen other review videos, but they don't really cover it like you would I think. Thanks again, I plan to at least drill the holes, and may even dink with 3D printing a new diffuser for my Eastwood gun.
Sorry for the delayed response. Thanks, and yes. :) I've been thinking of it for a while. Could never justify the cost. But with youtubes change, I now need 15 more subscribers within 30 days to keep my monetization. This seemed like a great way to get a few more subs (new videos usually bring more subs) So I actually went out tonight and picked one up. Expect the review in a few weeks. If you do design a new tip and make it public, post a link in a new comment. I'll pin it to the top.
610GARAGE oh I just saw your reply. Thanks for doing that. I'll sub! I think powder coating is lacking a well informed group of creators who have any knowledge beyond "look I powder coated a tumbler!" Which they then post on Tumblr... Ironic. About I look forward to the review. I'm going to be doing a vid on powder coating PLA 3D prints, as soon as I get around to sitting down and editing my crappy phone footage. PS the 3D printed diffuser works well, and I sharpened the tip of the original electrode with a file. Seems to help with transfer efficiency.
LOL Thanks. I'm writing the script now. But the way it's been going. The video is still weeks out. :( How does the 3d print powder coating work? I often thought about powder coating my 3d prints. It would be perfect to smooth them out. But powder coating needs 204c and pla starts to melt at around the 180c mark. Good to hear.
A low-cure powder is part of the key to this. You must have a supplier who can produce a powder that cures below 300°F. Often they are epoxies, and have limits on look/feel. I'm going to be releasing a video at some point on how to do it.
Me too. Are the electrical components already assembled? Would like to see this process so I can understand more about how the voltage is generated. Hope you go forward with this!
Here you go. I would add it to the description, but it's ebay. The link would break in a few months. ebay.com/itm/aftermarket-universal-head-of-powder-coating-gun-round-and-flat-nozzle/172434347756
Could someone please provide just a name brand and description of the tip to use?? I hate buying random parts only to not find the correct part, thanks for any help..
Unfortunately, I can not. From what I can remember, the tips were more of a grey market kind of thing. They were probably a copy of a popular powder coating gun, but of what system I do not know. WIth all that being said, I would bet that if the tips look the same, there probably the correct ones.
I know your pain. Here is the kit. I do believe you will also need an adequate power supply. But I have no idea what specs are needed. ebay.com/itm/aftermarket-replacement-shell-of-manual-powder-coating-spray-gun-HV-Cascade-PCB-/172429753138
This gun is garbage. Wish I would've just put forth more money into something better. What makes it even worse is their customer service seems to be non-existent. I know this video is somewhat old, but just wondering, What powder coating system are you using now? I'm thinking about going with the CC hypersmooth, but I'm now also hearing bad things about that one as well. I'm not really trying to spend 1k on a gun. Awesome video btw. Definitely will be doing those mods to my EW and see if its something usable by that point.
Is it? I haven't tried HF system, but it honestly wouldn't surprise me. Eastwood dropped the ball hard on there powder coating line. Evean there powders stink.
Appreciated you wrote down everything before narrating so I don't have to hear 'uh' and 'so like' a million times. But damn, you cannot read without sounding like a Speak'n'Spell. Hint, if your speech flow sounds the same if you're reading backwards as forwards, you're reading terribly.
Yes, I know. I don't talk well and it gets worse when I read. I try to ad inflections and the like, but the best way for me to get better is to keep on trying.
@@Kyle-fu6en I agree, clear concise & explained very well. I am brand new to Powder Caating & understood Josh very well. Much prefered to the "You Know" after every 7 words.
