hi, its been a long time, but i would love to see the pictures from your build! my HFGH just arrived today and I'm so excited to put it together without crying! Your profile on photobucket is set to private, would you mind sending me a link? thanks!

Greg, I will not be at the location with the greenhouse until the end of the week. I will be happy to post pictures of anything you need then. As for the corners, they look like tools_r_us's with the thicker #78 and #80 parts. This requires changing the short screw specified in the instructions to a long screw (i.e., three long screws instead of two longs and a short in part #14. This is accompanied with using four long screws in the other studs that you already noticed.)

tiger67, I'm sorry to hear about the loss of your greenhouse, especially so quickly. Have you tried your local Craigslist, to avoid shipping? tmc2009, ours has been up almost 4 1/2 years, and we do have very strong winds routinely, for hours at a time. No wind damage at all to this point, but we did reinforce the frame, and we screwed the panels to the frame, as suggested by many posts here on GardenWeb. I documented many of those suggestions in my blog, here: Building our Harbor Freight 10x12 Greenhouse However, 80 mph winds are very severe. 80 mph winds can take down whole trees, and do roof damage to buildings that aren't engineered to withstand it. Mine has not been tested to that degree (although my guess is it's probably withstood some gusts in the 55-60mph range.) I'm not really sure how many greenhouses (of any brand) across the country could withstand 80mph. In my opinion securing the panels to the frame with screws is critical, in addition to strengthening the frame. Hello to funnylady...!

rjinga, I took some pics for ya to help out. first this is from the outside looking up to the back left side(right form the outside lol) of the PC panals the bolt heads are hiden behind the tape tho but you can see everythingis sitting flush This pic is from the inside looking up to the back left corner. as long as you put your bolt and nut on the top holes of part #49 an the top hole of the corner post befor you add side wall diagnial part #80 everything will fit nice. By the way I added both parts 79 and 80 to my corner post and it really stiffened up the frame where I din't have to worie about the winds 10 - 20 mph for the next 2 days before I could get back to working on it Here is the camera up tight to the back panal looking up to the gutter and part #80 to the left. On the right side of the corner post you can see my weatherstriping and how there is no buldge. If I had turned that nut and bolt arround like you have in your 4th and 5th pics then it would be sticking out past the PC panal. I hope this helped. JBa3Fan .....
