Island Counter Overhang Support
Comments (3)Let me first attack your drawing as is, but I have a question about your Amastin supports. We are not worried about force, we are worried about torque. Torque A can be calculated by assuming that Force A acts at a point 12.5" to the right of the edge. Torque B is found by assuming Force B acts on a point 7.5" to the left of the edge. Torque C is found by assuming your clueless friend's weight acts 15" left of the edge. Torque A = 162 lb*12.5" = 168.75 lb-ft. Torque B = 101 lb*7.5" = 63 lb ft. To tip, Torque C would have to be 168.75 -63 lb-ft = 105.75 lb-ft. So, your clumsy friend would have to weigh 105.75 lb-ft/1.25 ft = 84.5 lb to tip your counter. Still not good. However, the effect of the Amastin overhang brace is to shift the pivot point to the left. I think you are supposed to get the one that is 33.25" long. I believe this would stick out from the back of the cabinet by 33.25" - 24" = 9.25". This would mean that the pivot will be about a point that is 9.25" left of the back edge of the counter. This changes your numbers to a much more favorable condition. Now, Force A is 18lb/ft^2*4.5ft*(25"+9.25")/(12"/ft) = 229.5 lb and acts (25"+9.25")/2 = 17.125" to the right of the pivot. Ergo, Torque A is 229lb*17.125"/(12"/ft) = 327.5 lb-ft. Force B is only 38.8 lb and Torque B is only 9 lb-ft. Your clumsy friend would have to weigh 664 lb. to tip the slab....See Morecountertop overhang needs support (retrofit) - help pls!
Comments (16)Thanks to those who provided specific input :) . Lowes Canada doesn't source the Federal Brace 8-in x 2-in Plain Steel Countertop Support Bracket. Any suggestions for Canadian sources of those? Or equivalent? Trebuchet, I assume I would need three of the Federal Brace 8-in x 2-in brackets? Could I install the plywood inside the cabinets (there is room)? Is there a reason why I wouldn't use the "L" shaped granite support brackets that don't have the cross-brace (knee knocking) like the example below? What about this Ekena Millwork 2"x8"x8" Hamilton Bracket? Price is good. Cold-rolled steel and it's supposed to be appropriate for granite. Is there any way to evaluate the many different brands of cold-rolled steel granite brackets? I am still trying to understand is shimming the bracket end(s) will be required to get a snug fit to the granite, and if so how would that be done? Kudzu, that supplier doesn't ship to Canada unfortunately. This post was edited by feisty68 on Mon, Dec 29, 14 at 13:32...See MoreCountertop overhang support with Ikea Sektion cabinets
Comments (1)Hi, i truly do not like the new metal bracket supports. The old Akurum cabinets had a piece that ran side to side in the front and back similar to what's in your picture. What I did was skip the metal supports and added the pieces from side to side in the front and back. My cabinets are white and I bought an interior shelf so that the front would have facing, but you could always buy the iron-on banding at Home Depot and it would look just as good. I had cover panels to add so I just screwed them in on the sides of the cabinets. However, I can see that you side is exposed. So You can either use 18 guage nails and then put a tip of putty to hide them or you can use 'L' brackets from underneath. Good Luck....See MoreCounter Top Installation Help for IKEA Sektion 15" Base Cabinets
Comments (7)I am not any further on the counter :) But I am still planning on using the ply as an underlay. Unless I don't, lol. The soapstone that I have on hold has a small ding in the surface. I can repair it by using epoxy and ground soapstone "crumbs". Then when dry it sands nicely and you really don't see it. I haven't actually bought the stone I have on hold, but its not going anywhere. They might have other remnants soon. I think I will drive there tomorrow and reassess the "ding" and maybe just go with it instead of waiting for something else to turn up. Just got the under cabinet LED lights installed today. I am still working on the crown at the top. I have one length in and have to cut a piece to finish it up. The space is to tight for me to fasten the crown as instructed. I am using extra strong velcro, that will hold 1lb/sqin. It has been working well for the top crown. I used velcro to attach the filler strips to the 2x4 backing at the ends of the cabinets too. It was great. The instructions for my style of crown have you attach the crown at the bottom of the uppers in a way that is not a good method. They have you directly screw through the bottom of the crown and up into the cabinet box. There is a narrow foam strip that gets applied between the crown and box which looks like it is used to block the gap between, so under cabinet lights don't show through. The foam works, but the screws don't finish flush. The screw heads are so obvious. I am going to back each screw out, one at a time, and counter sink the hole so the screw head will be recessed. Then I can cover the holes with a plug or wood filler. I would post a picture of my under cabinet lights but I haven't been able to post pictures for several days now. I don't know what gives....See MoreLisa
