Sanwa gates are really hard, made out of lexan. if they aren’t angled right they’ll cut into the actuator. I think the larger diameter of the kowal causes it to hit the gate at a different angle and will cut into it. What’s funny is that his new gates do exactly this, lol.
The angle that the actuator presses the switch pin is also a factor. Kowal actuators and other Seimitsu actuators that are flat press the the switch pin in while also pushing it to the side. Levered micros help to alleviate the stress.
Yeah. On that really dusty stick for that client, the Kowal actuator had a distinct groove carved into it from where he was riding the gate.
I warned him about it (both the actuator and riding the octo-gate), but the client still liked that setup, so I just cleaned it up for him. So until the next time when this issue comes up again with him…
What is bad when that dust gets into the switches, getting over the contacts inside and getting into the joystick’s grease fouling it.
Like I’ve always said though, if you feel comfortable with a setup that disintegrates over time it is perfectly OK. Just be prepared to replace things when needed.
Clean and replace parts as needed. Don’t be like the kid afraid to play with their toys.
Better designed parts should last and not have these issues crop up.

Well I would not want to discourage more business for me repairing and modding sticks.
I don’t think using an air duster after several months of use is terribly burdensome honestly, and I haven’t seen the wear ring that pops up on a JLF actuator bell appear on a kowal actuator. Either way, I agree that the seimitsu design- using levered switches with a straight wall actuator with less wear prone plastics at contact points- is better for durability (I would say feel as well, but that is of course subjective).
Paradise Arcade Shop has aluminum actuators that I like.
They don’t work well with my optical setup though so I’m stuck with the stock Sanwa one.
I don’t ride the gate hard but I sometimes do hit the gate when blocking… I just keep extras around incase I need to replace them.
it’s been said in this thread that “delrin =/= acetal” this could not be further from the truth
“Delrin” is a commerical nale for POM, trademarked by Dupont, other companies call it with a different trademarked name and there’s a whole list of competitors eahc with their own funny name.
“Acetal” is a misnomer used in the polymer industry specifically for POM and is widely accepted in the litterature almost since it has been discovered. It’s not the first time a product has a long name abbreviated for ease of use (in the industry) by emphasizing a small part of its chemical name/class (since POM is a polyacetal and a condensed formaldehyde polymer).
It’s official,
“Delrin” (virgin basic grade, homopolymer) = “Acetal” = “POM”.
Which means you can buy the most basic (and cheap) grade of “delrin” from Dupont and it will be on paper 100% POM homopolymer without additives, fillers etc, no other polymer blended in etc.
You waited two years to try to mansplain me the difference between two types of plastic?
You must be so proud of your self.
Hey, at least it’s informative. It could have been a noob post just affirming the previous years-old comment like “yeah, that’s dope, yo.”

No, its’s Agieze.
He has nothing of value to add, he just want to argue and prove he right.
He tries this shit with Paradise Arcade all the time, trying to explain to them how their own products work.
Darksakul you have to stop bullshittin’ noobs by handing them out false info without even checking. It’s not like if ebooks were hard to come by today.
Delrin is used a lot today, especially in the custom arcade parts world, so I thought that newcomers were in right to have valid info to start with if ever they searched this thread, nothing personal.
Suck it up and take it like a man.
Actually I do read you moron. Here some sources to back my claims.

https://www.directplastics.co.uk/about_plastics/why-choose-acetal-or-delrin
All I stated before despite being a POM, they are two diffrent plastics with two two different preferred uses
There is a mark difference, despite belonging to the same PolyOxyMethylene group of materials.
Derlin is stronger and harder, more heat resistant, while Acetal is certified safe for food (and a little softer).
You could of left this old thread alone, but you have to “mansplain” why you are “better” without offering any sources on the topic.
Now stop trolling everyone and go play in traffic.
Darksakul, you are the definition of a troll , and proud of it to make your case worse :
you post links which REINFORCE my statements (which are by the way common knowledge)
Example, https://lionep.com/uploads/files/Acetal-vs-Delrin.pdf
First paragraph :
"Acetal is available in two
general types
of resins:
Copolymer acetal (POM-C), and homopolymer acetal (POM-H) commonly called Delrin® "
“How is Delrin® different?
Delrin® is an acetal homopolymer and has a uniform backbone with a larger crystalline block structure than acetal copolymers”
it means the standard basic virgin grade DELRIN by Dupont = acetal homopolymer, is NOT a COPOLYMER ,as found with other companies (example HOSTAFORM by Celanese);
Dupont doesn’t like acetal copolymers and prefers homopolymer with fillers, alas you’ are totally uneducated and cannot even comprehend basic scientific English
Go back to school or STFU.
not only is delrin acetal, it is according to Dupont “better” than acetal copolymers produced by competitors;
Why is Dupont a little bit aggressive in their claims? Because certain grades of Ultraform (COpolymer from competitor BASF) for example is TRANSLUCID and Dupont didn’t come up with it, it has applications for lighting and some companies probably prefer a translucid copolymer of acetal (with another polymer) which permits it to pass light through, you get the picture (do you? really? hmmm…)
once again you have no friggen clue about plastics.
The sad part is you don’t even understand a commercial claim nor the difference between copolymer and homopolymer, I mean it is LITERALLY WRITTEN EVERYWHERE on the website as drawings, charts, tech sheets… “DELRIN HOMOpolymer versus ACETAL COpolymer”. I even explained to you in my initial post that BASIC VIRGIN GRADE of DELRIN (since it is a homopolymer) = POM = acetal, but since acetal in the vague sense (it is a commercial/industrial name, but NOT trademarked like Delrin) designates ALL the class of polyacetals, it also includes copolymers that are far from the virgin grade (or even grades based on homopolymer with additives+fillers+uv block+etc), is that so hard to understand? (Btw Delrin is also vague, as it designs a whole class of various acetal products all based on homopolymer acetal but with various additives that can reach a substantial percentage by mass). I mean it’s really simple.
Celanese, a (historical) competitor of Dupont, is specialized in COPOLYMER POM/ACETAL and thus they wrote a paper LITERALLY CLAIMING THE OPPOSITE OF WHAT DUPONT CLAIMS, stating homopolymer POM is superior only on short term use,no special or extreme condiitions, while the POM copolymers are tougher on the long term, more resilient etc etc :
https://www.celanese.com/engineered-materials/products/Hostaform-POM--Celcon-POM/Homopolymer-vs-Copolymer.aspx?utm_source=ChemistryInside&utm_medium=blog&utm_campaign=CopolymerVsHomopolymer
In no way , shape or form does that imply that Dupont’s Delrin is “not” acetal. It is actually, just the homopolymer form
Everything you wrote is plain retarded. Dupont simply made their case for Delrin (acetal homopolymer) against all the other competing acetal copolymers, simply because Dupont specializes in homopolymer , end of story, you’re really trolling hard there Darkyboy.
And I think we are done. Don’t speak to me or reply to comments/threads I am in ever again.
As I just going to ignore you for now on, as there nothing of value you can ever say.
You got nothing there but attacks and bad circular logic.
Keep you threats to yourself and man up.
Next time instead of googling things up in 2mn like you always do, posting links without even reading them , perhaps you’ll think twice.
Good riddance !!
