Question about making your own R-hop patch

I was going through the forums and saw a couple of people mention McMaster-Carr as the source for r-hop patch tubing. However I wasn’t able to locate one with the correct dimensions nor were they made out of silicone (unless I’m mistaken in that they should be made of silicone?)

I was wondering if people here already knew what the “goto” source tube/manufacture was?

Additionally, has anyone had put together a guide for cutting of said patch?

For tubing, https://www.mcmaster.com/5041K24

The original rhop tube Hunterseeker used was EPDM.

@Plazmaburn

Thanx for the 411
I was looking for a 8.5mm outer and 6.0mm inner diameter tubing - I rather not take sandpaper to my barrel if I could avoid it

Supposedly they are made, but I'm not sure what application they are for or if they are even sold state side

The 8mm is supposedly closer to 8.5 but is a tiny bit smaller.
People have made it work and recommend it, but you should go with 9mm and use one of these https://www.uline.com/Product/Detail...E&gclsrc=aw.ds

and this

This guy has a bunch of other cool looking stuff that I hope to try eventually, but I'm good with standard buckings for now.

Funny you posted about the hop plane. I have a review of that entire system. (I was going to post the link but my phone is not cooperating with me.) It's in the reviews section of the forum.
It works. Just make sure you use lube.

Awesome!
Is the whole setup worth buying if you have never done an R-hop?

Hello gents, how do you think - is there any other source for tubing? Mcmaster refused to send me anything to EU...

I was told that this stuff is quite good by another EU guy.
https://www.ebay.com/itm/6mm-x-9mm-S....c101072.m2109

I wish I could find out the stuff that Snipetor uses as it appears to be perfect in terms of sizing as well as being 60º or 65º.

Thank you for the lead
The theory behind it seems sound, however I wonder about practical application. Based on what I see, you have to glue the rhop in before making the cut, which essentially commits the barrel. So many people talk about putting rhops on, but no one talks about how to take it off if a mistake is made.

I wonder if during the cutting process there will be any unevenness in the patch because of sheering forces?

I think my issue is I don’t know the tolerance level and I might be overestimating the amount of accuracy these dimensions need to be

Here is a playlist I made that may have some good info

Excuse the other stuff as some of it is for other things

here is the link. https://www.airsoftsniperforum.com/3...em-review.html

To cut straight to it, I think it could have some improvements made, but I do like the system. Its only really worth it if you are doing multiple guns. if you are only doing 1 then just buy a pre-made patch from elvishtac or someone.

Since I will be ordering, modding, and making, yes, MAKING some barrels in the nearish future so I won't really be able to put in a pre-cut patch.
I will also be testing different windows and I definitely won't be paying some monkey $50+ to put in a piece of questionable rubber tube and scratch the @$!#%$^%&*#@$%^&**%*^%$^ out of my expensive barrels.
Mayben I'll even do a really long ER-hop and post some testing here if I want to be mean to a stock barrel lol
Lots an lots of stuff I want to do.....
Maybe someone could find out what Elvishtac, Snipetor or Faceless use for tube since that stuff looks superb and it would make it easier for people to try their hand at R-hopping.
Also, does anyone know how pre-cut patches are made?
They look so nice which makes me really curious.

Funny you mention elvishtac — I had contacted them about two months back in regards to patch compatibility
They had patches for some barrels I was interested in…but unfortunately not all. Hence I’m weighting my options between switching my barrel choices or risk attempting to make patches myself.

@siliconesword

I spoke to a couple of machinist and they had suggested various jigs like the ones you reviewed. However the solutions they gave were very cost prohibitive because of the precision and materials they were suggesting. Part of the problem was my inability to share with them the level of tolerance that a patch dimension could be off by or the various characteristics of silicone material

From what I understand most of the precut patches are laser cut or waterjet cut.
