Matt Parvis Posted February 26, 2021 Share Posted February 26, 2021 Manfred, I don't have experience with the RP Toolz cutter, but, I do have a Chopper. It works fine, but, for the level of precision you work at I suspect it would not meet your needs. Cuts it makes aren't perfectly square and the marking and measuring guides aren't particularly precise. Keep up the good work, I always enjoy seeing the latest craziness you are up to with this project. Matt Link to comment Share on other sites More sharing options...

I'm going to give you the benefit of the doubt and assume you're not being snotty, and tell you that 1) I can't because I don't know. 2) I don't know. I'm the forum owner and admin, not the person that coded the forum. Ask Invision if you really want the nitty gritty, as that's above my pay grade.

roma847 Posted February 27, 2021 Author Share Posted February 27, 2021 Sorry Mike, but these were questions regarding technical problems that had occurred during users' communication, which were in no way meant to be personal and certainly not to be rude. Therefore the problems should be forwarded to whoever coded the forum and who may be able to answer them, so that these problems are resolved.

roma847 Posted March 1, 2021 Author Share Posted March 1, 2021 Hello everybody, and now here is the thing, and as expected and hoped for, it also makes a really solid impression, with a high rigidity of the blade fastened with Allen screws, which is very important with such precision tools! Contrary to my assumption, the cutting blades are not only sharpened on one side, but on both sides (1 mm). I also still had ordered 5 replacement blades (0,25 mm and 0,3 mm). After looking at the part from all sides, I've of course also tried it out with different Evergreen profiles, such as: - Tube Ø 5,6 mm - Rod Ø 4,0 mm - Box profile 3 mm x 3 mm - Strip 3,2 mm x 1,5 mm And as one can see, the quality of the cuts is really impressive. Here is a Miter cut (45°) through a H-Column (3,2 mm), as well as a cut through a Balsa strip (2 mm), across the grain, which is also completely problem-free, as one can see. In addition, according to the description, this cutter should also be suitable for soft metals, which I've tested with my silver-plated copper wires (Ø 0,4 mm). For this I've put 5 wires next to each other and set a length of 10 mm with the side stop. So that nothing could slip, I've only temporarily fixed the wires with a steel ruler, that could also be clamped if necessary, and then did cut with one cut, which is easily feasible with this diameter. Maybe it is possible that the number of wires per cut can also be increased, which should be tested. With it nothing should stand in the way of producing the needed Connecting pins for the Crawler chains. On closer inspection, I noticed two more drilled holes on the back of the lever, which there are probably not without reason there. Since the dealer (Rai-Ro) could not answer that, I will inquire about it at the producer RP TOOLZ. So much for my first impressions of this great tool. 3 1 Link to comment Share on other sites More sharing options...
Arild Moland Posted March 2, 2021 Share Posted March 2, 2021 From the pictures you post here on the RP Toolz cutter, it looks like you made the right choice. Like Matt, I also have the Chopper you considered, and from what I can tell, the RP thingy is superior. Makes me want one, actually. One thing that "worries" me, though, is your plan to cut metal wire. Unless this is very soft wire, I would expect the cutter blades to be dulled and dented rather quickly, but only you are in a position to tell.

Arild I had this cutter on my list for a longer time, but at the latest after I have closer delt with the manufacture of the connecting pins for the 456 Track Shoes of the 8 Crawler chains it was clear to me, if not now, when then! And that one would also be able to cut the thin 0,4 mm copper wires, I somehow had a feeling and have planned from the outset, which the tests also showed. That's why I quickly discarded the 0,4 mm steel wire variant, because that surely would have been the Blade killer in shortest time. Link to comment Share on other sites More sharing options...

Well, I can now recommend this cutter with a clear conscience, after having convinced myself of its quality, precision and robustness. Small but nice, and all in all a really great tool. Here is a similar, interesting Video with more and use cases and details. I've also contacted the Hungarian company RP Toolz today to find out something about the two yellow circled additional threaded holes, because they will make some sense. Maybe there are still other blades. Please let us know your experiences using the cutter. Link to comment Share on other sites More sharing options...
roma847 Posted March 3, 2021 Author Share Posted March 3, 2021 Hello everybody, hardly asked, and the answer came from RP Toolz already, according to which other blades can also be used. While for the Miter Cutter German Martor blades are used, one can also use these Stanley trapezoidal blades, which with 0,65 mm blade thickness are somewhat more robust and suitable for coarser material. And for clamping these blades the two central threaded holes are provided. Source: amazon.de With it one could probably cut thicker wires made of soft material too. 3 Link to comment Share on other sites More sharing options...
roma847 Posted March 4, 2021 Author Share Posted March 4, 2021 Hello everybody, yesterday I've received this photo from RP Toolz showing one of the matching Stanley trapezoidal blades with a blade thickness of 0,65 mm, Source: RP Toolz (Peter Horvath) which one can order here at amazon, Source: amazon.de which I've done right away too. 2 Link to comment Share on other sites More sharing options...
roma847 Posted March 6, 2021 Author Share Posted March 6, 2021 Hello everybody, to try out these Stanley blades, I've ordered 10 pieces, which have already arrived. While the holes (Ø 2,9 mm) of the Martor blades fit exactly to the threaded holes of the Miter cutter, surprisingly there were problems when clamping the Stanley blade because the distance between the two recesses does not quite match that of the threaded holes in the new cutter. As a result, the blade can only be screwed tight with difficulty and does not sit optimally too, which would be problematic regarding the tool life of both the Allen screw and the threaded hole of the cutter. Since a complaint regarding the Stanley blades would not be expedient, I could try to widen the left recess (3,4 mm) a little, which I've also successfully done at the first go with a small diamond round file, whereby this blade could now also be screwed tight, and is therefore ready for testing on the 0,4 mm copper wires. 3 Link to comment Share on other sites More sharing options...
roma847 Posted March 10, 2021 Author Share Posted March 10, 2021 Hello everybody, in the meantime I have fiddled around with the production of the connecting pins and, among other things, and have tried, brave as I am, to cut 10 wires all at once to test the limits of what is feasible. I came to the conclusion that 10 mm would be a sufficient length for the cutting and have set the side stop accordingly. In order to be able to slide the bundle after each cut against the stop and to prevent the wires from flying away, I fixed it with several strips of tape, and placed it at the stop. When cutting I had to exert a noticeable pressure with the lever, but then it made Crack, and most of the first 10 pins had disappeared, which then gradually found themselves scattered on the tile floor. It's just good that the silver-plated pins are shiny and were relatively easy to find. So I was just too quick with the matter and hadn't thought of the downholder, which I had actually thought about exactly for this purpose beforehand. And since adversity is the school of wisdom, I've put an 8 mm wide steel block next to the stop for the second cut and hoped for its help, what then also proved its worth. And then it went on easily with the next cuts the same way ... And these first 50 pins are now waiting to be bent and then trimmed. BTW, in this video that I came across by chance, I've seen (I didn't understand anything because I don't speak Japanese) that there is obviously also a double stop for the Miter Cutter, which would of course be helpful for certain things. After that I've asked at RP Toolz and found out that this stop was made for the Sujiborido Company and is only available in Japan. And since I meanwhile have a good rapport with Peter Horvarth due to my interest and inquiries about the blades, he graciously wants to send me such a stop for free, which of course surprised me and pleased me. 3 Link to comment Share on other sites More sharing options...
roma847 Posted March 11, 2021 Author Share Posted March 11, 2021 Hello everybody, in the meantime I have also learned from RP Toolz (Peter Horvarth) that the trapezoidal blade from Martor 5233.70 is a blade with 1-sided sharpening and 0,63 mm material thickness, which fits the Miter Cutter, as one can see in this image, so I have ordered 10 pcs. of which at rs-shopping. Source: RP Toolz (Peter Horvarth) The same blade is also available with a TiN coating, but for twice the price (10 pcs. 16,55 €). And therewith the next steps are now the bending & cutting down of the wires, whereby I will proceed as I've described it in my Post February 25. For fun, I've counted the number of hand movements per pin and came up with 11 just for bending & crimping, which I hadn't suspected initially! - Holder tubule into the left hand - Pin into the right hand - Threading pen into the tubule - Taking crimping pliers - crimping the pin end - Putting pliers aside - Placing the tubule with the pin onto steel ruler and bending the crimped end - Taking chisel cutter - Cutting off crimped overhang (2x) - Putting chisel cutter aside - Ejecting the pin from the tube Next please! In addition there are now still approx. 5 further hand movements during cutting off the crimped barb to the final length of 6 mm, which I will do, however, as a precaution, using a single-cut process so as not to produce too lots of waste. However, I had to give up my previous variant of cutting off on the cutting mat, since my chisel cutter has probably become too blunt and has therefore only bent the overhang, which is why I had to use a sheet of steel as a base, which then enables cutting off even with the blunted chisel cutter, at least until my re-order of new chisel blades has arrived. That is then in total approx. 16 actions, which have to be carried out 456 times, so more than 7.296 in total, in case nothing falls out of my hands during this stressful fiddling. And if I'm honest, I have to admit that I am now shocked myself at this number and thinking about whether I should really do this to myself? I have already been asked about this whether it would not be sufficient to glue the chain links together, at least in the straight areas of the chains. But as a crazy lover for details, I will probably make this extreme effort and not shrink back for fear of my own courage. 3 Link to comment Share on other sites More sharing options...

roma847 Posted March 11, 2021 Author Share Posted March 11, 2021 Hello everybody, today the continuation of the pin cutting off was on the program, i.e. patience and perseverance were required for this monotonous work ... The box with the pins looks relatively harmless in itself, But the job is pretty stressful, not only for the eyes, but also the back (lumbar spine) because of the constantly stooped posture. But the first 104 of 456 pins are now finished, at least the beginning has been made. Now I can start the next small series, for which I first have to cut off pin-bundles on the cutter to 10 mm and then crimp their ends and bend them into barbs, i.e. the same procedure as before ... The squirrel has a hard time feeding itself ... 1 Link to comment Share on other sites More sharing options...

roma847 Posted March 13, 2021 Author Share Posted March 13, 2021 Hello everybody, Peter Horvarth, RP Toolz, quickly kept his word, because yesterday his package arrived from Hungary with the promised Double stop for the Miter Cutter, together with two trapezoidal blades, franked with 2270 Forints (6,18 €), which he did post on Tuesday (03/09/21) in Balatonfüred. Look here, that's what I call Customer Service - Made in Hungary! Of course, I installed the Double stop right away, and also the 0,63 mm thick Martor blade (5233.70) with a 1-sided cut. With that I am now also prepared for somewhat stronger things. 2 Link to comment Share on other sites More sharing options...
