Groomlakearea51 Posted October 26, 2008 Author Share Posted October 26, 2008 60 When you cut cloth, be liberal and whatever you do, do not cut it with an insufficient edge to roll it over and glue it to the grill board. To small = ruined, wasted piece of expensive cloth. Rule is: 3/4" extra all way round for Heresy's & LaScala's, and about 1" for Cornwalls. Klipschorns & Belles? about 1.5" minimum.....

Groomlakearea51 Posted October 26, 2008 Author Share Posted October 26, 2008 62 After trimming, I "melt" the edges to prevent unravelling. BE CAREFUL.... The cloth is a polyolefin resin (plastic....) and will melt and burn..... Quote Link to comment Share on other sites More sharing options...
Groomlakearea51 Posted October 26, 2008 Author Share Posted October 26, 2008 63 Remember that pair of cloth clamps you made? Well..... Here yah go!!! Put the cloth in between the bottom board and the second board (notice the wedges to hold the gap open). This is probably the most critical part of installing the cloth. Make sure you align a seam along the clamp edge before pulling the wedges and tightening down the nuts..... Quote Link to comment Share on other sites More sharing options...
Groomlakearea51 Posted October 26, 2008 Author Share Posted October 26, 2008 64 Clamping down the Heresy cloth. I use "nuts" instead of wingnuts on these clamps. No real difference. Remember I said about the bolts have to be exactly the same distance from the edge, as in 3/4"? Well.... Quote Link to comment Share on other sites More sharing options...
Groomlakearea51 Posted October 26, 2008 Author Share Posted October 26, 2008 65 Here's why.... You are going to put the motor board template between the cloth clamps. With the edges of the cloth inserted just less than 3/4", the motor board template is about 1/32" narrower than the cloth. That's going to be very important when you stretch the cloth...

Groomlakearea51 Posted October 26, 2008 Author Share Posted October 26, 2008 66 Same with the Cornwall.... Quote Link to comment Share on other sites More sharing options...
Groomlakearea51 Posted October 26, 2008 Author Share Posted October 26, 2008 67 Clamp one of the grill cloth clamp board assemblies down to your workbench. Now insert wedges on the other non-clamped assembly at the top and the bottom (only on that one side!). Do it evenly. As you push the wedges in ever so slightly, you will see the cloth get tight. Don't overdo it. Just enough so it's "flat" across the motor board template. Quote Link to comment Share on other sites More sharing options...
Groomlakearea51 Posted October 26, 2008 Author Share Posted October 26, 2008 68 Lay one of your grills flush along a clamp edge and check for vertical alignment. You are looking to make sure that the top edge of the grill board runs along a seam when aligned. If not, release the wedges and carefully move the cloth clamp assembly up or down accordingly. Be careful, you only need to move it about 1/32" of an inch. Re-insert the wedges and check it again. Quote Link to comment Share on other sites More sharing options...
Groomlakearea51 Posted October 26, 2008 Author Share Posted October 26, 2008 69 You can clearly see the wedge system and proper vertical and horizontal alignment. Very carefully lift up the grill board..... Quote Link to comment Share on other sites More sharing options...
Groomlakearea51 Posted October 26, 2008 Author Share Posted October 26, 2008 70 Using the 3M77 adhesive... spray a good coat on the "rough" side of the grill board. Let it sit for at least 5 minutes to "tack up". Touch it after 5 minutes and your finger should stick to it, but not lift any adhesive.

Groomlakearea51 Posted October 26, 2008 Author Share Posted October 26, 2008 71 In the case of the Cornwalls, I always use "extra" cloth and have an additional 3/4" on one side. Reason? because it's a lot of cloth and when I get ready to lay the "adhesive" grill board on the cloth, I use a strip of painters tape to make sure it's aligned on a vertical seam.

Groomlakearea51 Posted October 26, 2008 Author Share Posted October 26, 2008 72 Here you go. That adhesive is tacky enough that once the board is placed on the perfectly straight and tight cloth, the cloth won't move. to make sure it won't move, I use a roller and press down on the board. Since the cloth is "sandwiched" between the template motor board and the grill board, it won't stretch or deform the cloth. Quote Link to comment Share on other sites More sharing options...
Groomlakearea51 Posted October 26, 2008 Author Share Posted October 26, 2008 73 Thar' yah go!!! tight and ready.... Let it sit for at least 30 minutes.... Quote Link to comment Share on other sites More sharing options...
Groomlakearea51 Posted October 26, 2008 Author Share Posted October 26, 2008 74 After letting it sit for about 30 minutes (minimum good cure time for the adhesive), remove the cloth clamps. Quote Link to comment Share on other sites More sharing options...
Groomlakearea51 Posted October 26, 2008 Author Share Posted October 26, 2008 75 Flip it over and check your work. If for some reason it is not straight, you can remove the cloth and do it again (the adhesive is an adhesive... not a glue...). Quote Link to comment Share on other sites More sharing options...
Groomlakearea51 Posted October 26, 2008 Author Share Posted October 26, 2008 76 What about cloth that has creases, or folds, etc.? Quote Link to comment Share on other sites More sharing options...
Groomlakearea51 Posted October 26, 2008 Author Share Posted October 26, 2008 77 No problem.... clamp it down evenly as described. Now just so you can see what heat does to polyolefin resin threads..... Here's a couple threads that are "not tight". In order to tighten them up you have to know what the plastic deformation & melting points are for the cloth as it relates to YOUR hairdryer..... THIS IS IMPORTANT....

Groomlakearea51 Posted October 26, 2008 Author Share Posted October 26, 2008 78 In this case, the threads will shrink with approximately 3 seconds at 3 inches of the hot air. This is without "deformation", or causing the threads to become "plastic" and fuse together. Quote Link to comment Share on other sites More sharing options...
Groomlakearea51 Posted October 26, 2008 Author Share Posted October 26, 2008 5 seconds will either melt the threads or cause the fibers to fuse.... Not good. If you do not know what that hair dryer will do, you will ruin a grill in short order. Quote Link to comment Share on other sites More sharing options...
