JVC M90 screws and switch cap

[Trommelmops]

So I'm finished today the needed screws

Here the final result of what he get from me

all self-made screws are have a PH 1 driver

 

[caution]

Yes actually 1.65mm is VERY close to 0.065", which is 1.651 mm, or 15.38 threads/inch. No inch-based screw uses a fractional value for this.

But metric defines the actual thread pitch, so this screw would be M4x1.65. This makes more sense because I can buy M3.5x1.65 screws, but nothing in M4 Very odd screw.

I like that you also adjusted the thread shape to perform optimally in plastic

 

[Trommelmops]

It exists screws for plastic in a special norm. There I have the shape from.
I have compared the exist scews with mine. The shape of the thread angles are defined.

And I have grind the lathe tool to these special angles.

my screws are better than the originals

but screws with m3 X 1,65 I have never seen and where have you see these screws? The problem with the screws is that they are not cutted they will be roll forged.


Oh m3,5 sorry but this is easy........

I can do this......

I have thread cutters here in m3,5

Stop!!!! M3,5 have definetly not this Pitch!!!

Where have you seen the screws with 1,65 Pitch??????????????

omg that is supper cool saves me from going to my parents house to look for extra screws, unless you still need them?

 

[caution]

Where have you seen the screws with 1,65 Pitch??????????????

Plastite 45, Remform, Remform II and Remform II HS all have close versions, but nothing at m4x1.65.

There's probably other companies that make these, but didn't look too hard....
Probably in Japan somewhere that I cannot search

 

[Trommelmops]

I have found the Norm here in the file from you: I have marked it.

And so i did the screws.....

 

[caution]

Yeah, I think that's about as close as we're going to get

 

[Trommelmops]

Little update:

in the meantime i have try out to create a switchcap.....And let me say the following:

At this moment one of the testcaps is on the way to blue_fuz that he can tell me about the fitting and some other questions i will have........

This is only for a test, i have one made in alu....should be a little surprise to him

I know i have told that this isnt possible, but i changed my own opinion: One smart guy sayed to me: Trommelmops what you not do you cannot learn

Oh he's so right......

Im sure you see the first testcap which isnt not yet finished to 100% on a picture soon.....

 

[blu_fuz]

Can't wait to try these screws! Thank you.

 

[Trommelmops]

Looks good and when they have a little to much pitch I can do the correct pitch now

From now on I can make them in 1.65mm pitch and can change the lathe tool a little......

 

[blu_fuz]

They are very close thread count and pitch. Could be adjusted a little, I can get more dimensions for you. I will try tonight.

 

[Trommelmops]

Not needed Joe I have all info's.....

More needed is the switch cap.....if it fits

Then I have the correct dimension and can make a final one

 

[blu_fuz]

The little cap is beautiful, I will check the fitting of that as well.

 

[blu_fuz]

The screws worked!!!!! Used all of the long ones you sent!

The switch cap needs more tweeking.

 

[Trommelmops]

OK...i need help to understand: Is the gap to tight? Which thickness has the slidermaterial?

I have made the testthing with 1.15mm gap but i think is 1.2mm?????

I need then a new measurement from you with the correct thickness......

Cool that the screws working

 

[Timecop1987]

Trommelmops - Is it possible to recreate some more M90-screws? Mine is missing 4 of these! Hit me up (I speak german aswell)

 

[blu_fuz]

Hey Timecop, he sent me some extras I will send to you. PM'd

 

[Trommelmops]

if anybody need some more or different screws or something else i can made......let me know

The Mops was very busy the last time

 

[docs]

Got me thinking about the switch caps needed for M90.
Trommelmops, maybe I/we could provide you with the actual lever/switch needed for the cap to fit?
Would that be of use to you?

 

[Trommelmops]

Im sorry Dave, my english is worst. Have problems to understand it.......Can you explain it for a foreigner pls a little easier
