Also, can the cane grill material be installed using the the same 3m spray adhesive? Quote Link to comment Share on other sites More sharing options...

mopardave Posted February 6, 2018 Author Share Posted February 6, 2018 Ok' would the old adhesive need to be removed or can i just go over top with the cane. Quote Link to comment Share on other sites More sharing options...
dtr20 Posted February 6, 2018 Share Posted February 6, 2018 Heat it up and try to scrape off the old adhesive while it's still gooey. Quote Link to comment Share on other sites More sharing options...
mopardave Posted February 6, 2018 Author Share Posted February 6, 2018 Ok, thanks. Next question. Does the cane material need to be stretched tight when its applied? The black nylon material i used previously did not require stretching tight. Quote Link to comment Share on other sites More sharing options...
avguytx Posted February 6, 2018 Share Posted February 6, 2018 Cane material like Klipsch speaker grill cloth? If it's like the Heritage line, that is NOT a stretchy material like typical black acoustically transparent grill cloth you buy most anywhere. You have to line up the "grid" all the way across and make sure it stays lined up all the way horizontally and vertically. How did you apply the original grill cloth? And is "old black grill material" the grill cloth I mentioned above? If it's not stapled on, just pull it off and be done with it. There shouldn't be that much glue that would matter in going over with new cane grill IF you used something like 3M Super 77 adhesive. Are they stapled as well or just glue? Too many variables here. Any pictures of backsides of grill? I've made, covered, recovered, etc., etc., hundreds of grills since about 1980 so shouldn't be a big deal. What about just building a new pair so you're starting with a clean slate? Aren't Cornwall grills made out of some sort of 1/4" material like masonite or MDF? Those would be easy.

The cane material i have now came from Bob Crites. When i built the CW's i also built the grill panels out of masonite. I layed the nylon grill material on the floor, sprayed the panels with 3m 77 and layed the panels on the material. Cut, trimmed around edges, glued and folded. The black material was very stiff and hard to fold. Quote Link to comment Share on other sites More sharing options...
mopardave Posted February 6, 2018 Author Share Posted February 6, 2018 Looks like ill have to lay panels down, spray them with 3m 77 and lay the tweed/cane cloth on them. I will be able to see what im doing that way to be sure lines are straight. Quote Link to comment Share on other sites More sharing options...
jason str Posted February 6, 2018 Share Posted February 6, 2018 You can try paint stripper but you may end up sanding it off. May be easier to make new one's if it gets sticky. Quote Link to comment Share on other sites More sharing options...
avguytx Posted February 6, 2018 Share Posted February 6, 2018 Plus you could leave some of the black threads and it potentially show through or make the cane cloth bulge from the old parts being underneath. You could try a hair dryer on its hot setting and use a paint scraper, of sorts, and push underneath the material. It's going to leave a sticky residue so be careful what you're laying the grills on.

mopardave Posted February 7, 2018 Author Share Posted February 7, 2018 ok, thanks for the info on this guys. I never used a staple with the black nylon covering, just adhesive and it is very hard to work with. The black i used was very stiff and hard to fold. Think i can get it done.

Here's the "cane grill from Mr. Crites @BEC on a pair of Heresy that I recovered. Jason STR covered my CW grills with the black cloth now used by Klipsch, he said it wasn't the easiest to work with. The material from Mr.Crites was easy to work with , 3M R77 spray Mark 1 Quote Link to comment Share on other sites More sharing options...
