*DIY* Rhop IRM or IERM Nub

DISCLAIMER:
PLEASE READ THE ENTIRE TUTORIAL BEFORE FOLLOWING IT SINCE SOME STEPS OR TIPS MAY BE OUT OF ORDER AND WILL BE UP TO YOUR BRAIN TO REORGANIZE. ALSO, I TOOK THE TIME TO MAKE THIS TUTORIAL AND IT CONSISTS OF ALL MY ORIGINAL IDEAS, WORK, & PICTURES AND DO NOT WISH FOR IT TO BE COPIED AND CLAIMED AS YOUR OWN WORK.

Introduction! This is pointless you have permission to skip this.

*This is my first tutorial - it is quite wordy, but all input will be appreciated*

So, you just bought your IR-hop or normal R-Hop patch and were going to go buy an M-Nub and then you realized...

"Wait... that's expensive" or "Whoah... why is that flat?"

Well... whatever your reason. I happen to have created a tutorial for those of you that don't want an M-Nub or those that wish to try something that when done right could work better than an M-Nub.
^ (Absolutely no scientific or non-scientific evidence to back that previous statement, but this tutorial is budget-chair-softer approved)

If this was commercially being sold I would describe it as:
"A concave nub to be used in conjunction with an R-hop so that the nub provides even pressure over the entire patch and doesn't allow any side to side deviation (which is probably why you chose to R-hop your barrel to begin with). This product can also be used as a drop-in flat hop or G-hop solution too."

But anyway, here's what you will be creating.
(I apologize in advance for any health conditions that may occur from viewing pictures taken from my so called "digital camera")


Materials/Tools/Hazards There are many types of materials, but this is just what I chose to use.

- R-Hopped or IR-Hopped barrel
- Extra/Spare IR-Hop patches or R-Hop patches.
- Sharp pointy knife thingy (I use an exacto knife)
- Thin sheet of hard plastic (Optional, but highly recommended)
- Fine grit sandpaper so.. at least 120+ grit (Optional)
^This is never stated to be used in any steps during the tutorial, but it can be used to clean up any rough edges.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The plastic you select must be cuttable with some sense of precision with the pointy knife you selected, so I wouldn't recommend any plastic that is too hard or any blade that is over a foot long. (No Katanas)

Onward My Dear Fellows To The Tutorial What you actually came here for.

From here on in this section I will number the steps. By no means do you have to follow them in this order, but this is just how I did mine.

Step 1:
Grab the patch you selected and the blade of your choice. You will now cut it length-wise (the pink lines) to fit your hopup unit's window - (the square hole the nub pushes down through) and width-wise (the red lines) to fit your hopup unit's window.


Step 2:
Now you have your square cut patch, but the top is still curved and we can't have that now can we. So all you have to do is stand it up and slice down with your sharp object so that it is flat on top.



It should look like this when done.

(Notice how it is close to flush with the top of the window)



Your patch should not be extended into the chamber like it is in the last picture that was just to illustrate what it will look like. It should also not be slanted like that.

Step 3:
So now that you have your nub you can use it just like that, but That doesn't really help you that much. So now you need to add that thin piece of plastic to distribute the pressure over your entire patch.

For this I used these plastic label holders for binders, but use whatever you want. All you do now is just cut a square that matches the top of your patch you made.




Step 4:
Now before you get carried away you need to realize that this patch is 80% of the time too thick (Actual statistic taken by the Federal Burrow of Infestation) and unless you plan on over-hopping .4s you will need to cut it down. You can either cut the patch or the arm. (Or both if it's really bad)

Be careful when doing either of the following two methods. If you take off too much material you can create a "dead zone" where turning your gears doesn't change your hop setting at all.

Method 1:
You can shave off the the piece that is sticking out from the hopup arm. (cut or sand down the spikes that are coming out from the red line) This is normally used to hold the stock nub.

Method 2:
You can take off the plastic square you just cut and cut the patch. Just take off enough so that when the plastic square and the patch are together your hopup arm isn't putting any pressure or a very slight amount of pressure on the nub.

Here are some more pics for reference.



In the above picture the item labeled #1 is the nub and the item labeled #2 is your R-hop patch.

Step 5:
Now that you've fine tuned your patch to have little or no pressure when your hopup arm is in the off position, you can now glue the plastic square to the top of your patch so that it is one piece. And with my horrible French accent I say, "Voila". Now you're done and you can drop your nub in.



Conclusion Heh.. it's funny that you continue to read these since you think they actually say something important.
Since it's concave you should get results at least as good as an M-nub.
Also, because it's made out of the same material as your R-Hop it won't have different durometers, temperature flexes, and such... (I don't know... it made sense in my head - basically I'm trying to say that less differences in material tends to be better and more consistent.)

Thank you for taking time out of your chair-softing schedule to read this tutorial and if you enjoyed (or if you despise my existence) please take the time to comment, share, and everything else you wish to do to make this tutorial bigger and better. I hope you actually can put this tutorial to use and if not I hope you at least got a laugh out of it. Anyways... off to get some tea

Unsincerely, Torch

P.S. I will be constantly updating and editing this tutorial so it will not be finished for a long time.

P.S.S. I'm surprised you made it this far without taking a coffee break.

P.S.S.S. Stop wasting your time... seriously... There's nothing else down here.

P.S.S.S.S. Okay.. alright.. you win, here take a cookie.
