Forest Cobbler Posted January 20 Report Share Posted January 20 When I'm engraving acrylic or brass with a nose cone, I always protect the surface with adhesive vinyl. I was just wondering if any of you had come up with a quicker way, than using a scalpel and tweezers, to weed out the little bits of vinyl from the middle of the letters. Sometimes the clean up can take longer to do that the engraving does. Thanks, Valerie Quote Link to comment Share on other sites More sharing options...
Michael Posted January 20 Report Share Posted January 20 I weed the little middle of letter bits first with my finger nail. You can just scrape them without worrying about scratching the brass. Then peel the large bit off last. Quote Link to comment Share on other sites More sharing options...
Paul_ Posted January 20 Report Share Posted January 20 We have our machine hooked up to a dust extractor and most of the “middles” disappear during the engraving process. Very little is left to weed. Sarah Wise 1 Quote Link to comment Share on other sites More sharing options...
Happy Dude Posted January 24 Report Share Posted January 24 The edge of a clean piece of crepe removes all those annoying little bits on the a's and o's etc. Just a gentle rub is all it takes, doesn't mark the plastic... Quote Link to comment Share on other sites More sharing options...

Definitely going to give this a go too On 1/20/2023 at 7:55 PM, Paul_ said: We have our machine hooked up to a dust extractor and most of the “middles” disappear during the engraving process. Very little is left to weed. I used to use a vacuum to clear all the debris as the engraving was done, but it never took out the middle bits. Not a chance of persuading Mark to get a dust extractor instead :0 Thanks for all your suggestions, Valerie Quote Link to comment Share on other sites More sharing options...

Just tried both these ideas at the same time and I have to say that leaving the large area of vinyl till last certainly reduces the fear of scratching the surface, so thanks for that. But I have a question about the crepe:- Do you usually heat it up a bit first so that it's more sticky? I found that it just skipped over the surface most of the time. Will definitely persevere with it as an idea though. Thanks again, Valerie Quote Link to comment Share on other sites More sharing options...

Thanks again, Valerie Hi, i usually give the edge a quick scour on the finishing machine to bubble it up and clean it, sorry I never thought to include that info. i understand your concern re scratching, that's a good idea leaving the rest on while rubbing with the crepe but I've never found it necessary when I take the steps above...

Forest Cobbler Posted February 21 Author Report Share Posted February 21 That's great, thank you. I had a piece cut straight from a sheet but The Boss did say that he usually scours it a bit before using it to remove glue from a shoe. I should have listened to him Happy Dude 1 Quote Link to comment Share on other sites More sharing options...
Gray Posted February 21 Report Share Posted February 21 Stupid question but are you leaving the film on they come with? I buy precut sizes from Pantograph Services I don't really have an issue really Quote Link to comment Share on other sites More sharing options...

I buy precut sizes from Pantograph Services I don't really have an issue really No questions are stupid Sometimes I leave the film on, but mostly I don't. I've not found that it has made significant difference in the past, but maybe if I combine leaving the film on and using the crepe that will solve my problems.

Michael Posted February 22 Report Share Posted February 22 I always leave the film on and put a piece of scrap vinyl over the top, weed the little bits with my nail first then peel both layers off in one. Quote Link to comment Share on other sites More sharing options...

So, a nylon depth cone could be used, or correct the machine bed level issue and problem solved. Quote Link to comment Share on other sites More sharing options...
Forest Cobbler Posted February 23 Author Report Share Posted February 23 On the advice of Mark from U-marq, a few years ago I tried to correct the level of the flat bed by sticking on a piece of acrylic and then hatch engraving it from one corner to the other, which removed more material in the top left corner than it did in the bottom right. The level is definitely improved but not to the extent where I would be happy to engrave without a nose cone, particularly on larger pieces. Smaller bits are ok, but it is habit now to use a nose cone and vinyl no matter what size plate I am engraving and I don't have any problems with that, beyond how long it can take to remove the vinyl from the middles of small lettering. Using a combination of the suggestions from the other guys I think I can speed that up quite considerably. Just got to wait for an order for a brass or acrylic plate now to try it out Quote Link to comment Share on other sites More sharing options...
Forest Cobbler Posted March 4 Author Report Share Posted March 4 An update on how I am getting on with a combination of all your suggestions. I have done both a brass plate and an acrylic plate in the last few days. I don't think our crepe is quite the same as it used to be, it just doesn't seem to get as sticky as I remember, but with a bit of extra pressure the middles of the letters came away. Leaving the large area of vinyl on while working on the small bits is revolutionary, so much less stressful. Leaving the protective film on under the vinyl is where I have had most frustration. The crepe removes the vinyl but the film remains and can be the devils own job to release from the tiny middle of an 'e' for example. I think this may be the one that I don't use in future, sorry.
