sanwei rubber cutter without press

[ripctt2]

So i looked on aliexpress and found somehting similar to the sanwei rubber press (or machine idk tbh) https://www.aliexpress.com/item/1005011893867071.html?src=google but Ive also seen vids on yt that peole just put that on ansd then roll it with a ball tube or similar. would that produce a smooth edge as well with little to no overhang? as in would it produce as good of a result as you woudl get with the rubber press?

Yes, it works perfectly.
I have the very same item, I bought it last year and I've done three rackets with it including one just 3 days ago.
I just sandwich the racket, with this blade attached, between two small and strong sheets of wood (ensuring the handle is not touching) and stand on the top one, job done.
The cut is beautiful and looks like it came from the factory

I think im going to get it then to cut my rubber next itme. Last time i used a box cutter to cut it and it almost broke the knife. like there was a ton of overhang and it couldnt cut easily. chipped the wood as well

I bought this to mess around. They give you a rod to roll it with, but it's definitely better if pressed. Rolling works but you have to do it with the rubber side up - otherwise it's hard to cut through the rubber - and it lifts the edges a bit.

I like a little overhang, so I kept on with scissors.

can it not damage the wood ?????

No because you secure the belly of the blade to the edge. The cutting edge is touching the sponge to start.

what wait but is the overhang liek a lot of a tiny bit? i think i might get two wooden board and then ress hard on the top to reduce any overhang. a litle bit of lifting is fine. ill just glue 2 layers on spongre and 1 layer on blade. if theres no overhang i you do it the rubber side up, its fine by me and ill get one off aliexpress. one more thing, I see many of these types of cutters. are they all the same or are the cheaper ones like worse or have duller blade?

wait i just read your post again. did you say: stand on the top one??? would pressin down with your hands be sufficient?

No, I've actually found it to be safer than the box cutter.
I have nicked my blade with the box cutter before (my mistake of course) but it works as Dr Bean described above, once you attach the metal cutting blade around the edge of your racket there's no chance to damage it.

I stand on it simply because it's easier but I reckon rolling with a rolling pin and applying good pressure could also be enough but it does require a good strong pressure to cut cleanly ALL the way through.
I wouldn't do it by simply trying to press with my hands.
That's why they sell them with the press but unfortunately that part is too expensive and only worth it if you are assembling and selling rackets.

For me it was ~€18 well spent and, as easy as the box cutter is to use, it also demands care and attention to do it properly first time and achieve a really clean finish so I find this device easier.

I mean, this thing is totally not necessary and a bit overkill but hey, I'm a bit anal about wanting the racket to look perfect 🤷
There is a bit more overhang than you get with the box cutter, probably a 1mm more.
So if weight is an issue you'll want the box cutter to take that 1mm off, all the way around on both rubbers.
I wish I had a photo of the racket I did on Saturday but it was for a friend and he's put edge tape on it now.

Would this work with jpen blades?

You could always make a little press from two sheets of ply and 4 threaded bolts plus wing nuts. Basically how we used to dry leaves, tighten the nuts crosswise and equally and presto.

There's no overhang with this - if you cut it with the rubber side up is that the blade is essentially hanging on the rubber so when you roll the pin over the rubber it pushes the blade down, and the edges lift a little.

They are all the same.

Might be a little tricky since the head shape is quite square.

You're doing it proper. The rolling pin method with the rubber down is nigh on impossible, and it also distorts the angle the blade cuts at. You can also just straight up apply more force standing on it. You'd get maybe a third of that pressing on it with your hands.

 

[lodro]

I get this. Sometimes slowly, carefully niggling about is the proper way but when it comes to cutting soft rubbery things often a quick strong kick is the best way

Right on cue to urinate on a topic.

i suppose ill use a rolling pin cuz im not entirely sure what netprophet means by standing on it. as in setting it on the floor and then standing on it? but i dont think so. itll snap the handle. so not too sure.
wait someone answer this as well

i was considering getting that but it was a bit expensive at 99 aud so i wasnt going to get it. it seems a bit easy to accidentally roll of the edge and cut your. fingers so... but it was mainly tne price becuase it was more expensive than other thing i linked abo ve.

So basically:
1) Place a plastic cutting board on the ground.
2) Place the blade with cutter attached rubber side down on top of the board.
3) Place a piece of wood board on top of the blade+cutter combination - i.e. make a sandwich.
4) Stand on top of the wood board.
5) Repeat for other side.

And yes they're all essentially identical.

Would you like a smooth spread all over the blade surface? Then you need a glue mixture with some anionic/nonanionic surfactants inside, e.g. FAIRY CLEAN liquid soap.

Be happy all.

Be sure you only add the soap water solution to the bottle of glue. Dont use a pure soap, never.
