GazB Posted September 26, 2018 Share Posted September 26, 2018 (edited) So last year I got a rotary tool for Christmas, specifically this model https://www.amazon.co.uk/ROTARY-MULTI-PRECISION-DREMEL-COMPATIBLE/dp/B00PCIINKE/ref=cm_cr_arp_d_product_top?ie=UTF8 Thing is, I haven't used it once. I'm frankly terrified of using it because I hate the idea of something that cuts spinning at speed near my fingers (or the bit flying off). Unfortunately, I wanted it to make cutting resin plugs off easier, but alas that aforementioned fear sprang up. So I stumbled across those flexi shafts, which would be easier to wield than the tool itself, but they seem to be a mixed bag of cheapish ones with questionable longevity, and ones that seem made for Dremel only. Does anyone know of a good, fairly cheap and widely compatible flexi shaft? Or even recommend anything else for removing resin plugs quickly that didn't involve a rotary tool? I have a Trumpeter saw kit, but the blades flex a lot, and still take a bit of work to run through, which is a pain when you have a lot of resin stowage to work through. Or even a decent, reasonably priced tool. Cheers, Gaz Edited September 26, 2018 by GazB Link to comment Share on other sites More sharing options...
dogsbody Posted September 26, 2018 Share Posted September 26, 2018 I bought a Dremel unit at least 25 years ago. I added a speed control unit and a flexi-shaft. Sorry, but I can't help you with a price on modern units for Dremel. It works great. I used it recently to grind down the clear sprue that I used to make wingtip lights for my Airfix Hurricane. The tips were cut out and sprue superglued into place. After that set, the grinding commenced. Chris 1 Link to comment Share on other sites More sharing options...
GazB Posted September 26, 2018 Author Share Posted September 26, 2018 (edited) Thanks, Chris. What kind of speeds do you find optimum for working with plastic/resin without melting it?

GazB Posted September 26, 2018 Author Share Posted September 26, 2018 I've stumbled across this model: https://www.amazon.co.uk/PROXXON-28510-MICROMOT-drill-Voltage/dp/B000S5J5R6/ref=sr_1_2?ie=UTF8&qid=1537993772&sr=8-2&keywords=proxxon+micromot+50%2Fe Which I've seen being used by David Damek (PLASMO) on Youtube. I'm just curious though if the power supply is required. Some variants package that in with it, which doubles the price, but is it needed?

colin Posted September 26, 2018 Share Posted September 26, 2018 I wouldn't use a power tool to cut/grind resin unless you use a face mask, cutting resin with a power tools is creating a very fine dust which you don't want to be breathing in or have floating around your house. 2 Link to comment Share on other sites More sharing options...
dogsbody Posted September 26, 2018 Share Posted September 26, 2018 I'm not too sure just what rpm I was using. I think I had it set at about 2 on the dial, maybe a bit faster. I just went by feel. Definitely not full speed. That just melts plastic. On the tip lights I just roughed in the shape until I was close then switched to small hand files to get the proper shape. I then smoothed it out using fine grade Squadron sanding sticks. Chris 2 Link to comment Share on other sites More sharing options...
rayprit Posted September 26, 2018 Share Posted September 26, 2018 I model in resin quiet a lot and even though I have a Dremel close at hand, never consider using it for cutting pour blocks and with Accurate Armour they are big. I always use a saw, clogs the teeth up, but a quick wipe across the teeth with a wire brush soon cleans it up, if I do happen to use the Dremel for resin, it will be a short burst of seconds...…..I stuff cotton wool up my nose!!!(even though I have various face masks) I forget the last time I used my Dremel for Resin, relie entirely on pin vice and broaches. Plenty of saws around for cutting plastic and resin...……..you can buy a couple in a kit, small saw, big saw and a handle https://www.ebay.co.uk/itm/X-Acto-Razor-Miter-Saw-Set-Handle-/391980579014 But, its the a bit like scribers, glue or paint - each person has there own preference or favourites, somebody will be along in a moment and recommend what they use...……………...buy one and see how you get on with it, we have members on here who are tool stockists, check out there sites 1 Link to comment Share on other sites More sharing options...

A saw would probably cover most areas. I've used a mix of a little saw, knife and pliers (to snap stubs off where applicable). Some of the stowage I got recently has the stubs go in amongst some curved detail which was difficult to get to. Maybe a sturdy saw would be more cost effective for me.

dogsbody Posted September 26, 2018 Share Posted September 26, 2018 I have the Xacto saws mentioned above and I also have some CMK razor saw blades, one of which I have mounted in a larger Xacto handle; While trying to see if I could cut a CMK blade in two, so as to make a thinner saw, it shattered. I have mounted a piece into twist drill bit and use it for small jobs like removing parts from sprues. It works better than snips on small, thin parts.

I had one of my No.11 blades sheer where it was fixed into my handle. Went flying off and still haven't determined where it ended up.

bmwh548 Posted September 27, 2018 Share Posted September 27, 2018 From my experience each manufacturer uses a different thread on the front of the tool (where you attach the flexi-shaft). So in order to make sure it works on your Dremel you'll need to buy a Dremel flexi-shaft. Proxonn tools are nice, but you'll need the power supply to go with it (for the tool in your link at least). Pretty sure it's more cost effective to get the correct attachment for the Dremel you already have. And, like everyone already mentioned: make sure you use a face mask when cutting resin. I would also use an extractor if you have one to make sure the dust is quickly collected and doesn't start floating around the room. 1 Link to comment Share on other sites More sharing options...

I do have an extractor tube for my spray booth, would have to plonk it out the window. At the moment I may spring for the Tamiya saw and a pair of Tamiya side cutters (my original pair is probably 15 years old and starting to struggle a bit), and get them for roughly the same as the tool on its own. Thanks, though bmwh548 Gaz Link to comment Share on other sites More sharing options...
bzn20 Posted September 27, 2018 Share Posted September 27, 2018 First thing esp if you're not confident or just not sure is hold the piece as securely as possible ,try not to hold it in your hands if at all possible so it won't move , only the tool. The "secret" of a good cut is Hi speed and light feed, let the tool cut and not you pushing it ,no need to force it , gentle with it ,there is no rush and keeps the heat down . You will probably damage the tool ,the piece you're cutting/drilling and you when it flies out the other side ., scattering stuff all over your bench . You are unsure so have a practice , see how it feels and worse case you mess the test piece up and not your job Mask AND Goggles ..Goggles, Goggles . Only one pair of eyes and can't get new ones .At the speeds those cutters go at it's like shrapnel . 1 Link to comment Share on other sites More sharing options...
Stalker6Recon Posted April 27, 2019 Share Posted April 27, 2019 Did you ever sort out what you use with resin and other bits of cutting? I too am a bit gun shy of using my dremel tools, never used it on such delicate materials. My set, if it still works, has the flex bit, a router piece, a planar and some other fancy stuff. I have never figured out what half the accessories are even used for. I need to test it, and if still functional, start watching videos to see how it will help me with modeling.
