I do have 36" or wider doorways, Just making turns in the hallways would be an issue. ...Jim Thompson -- | James E.Thompson, CTO | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 Skype: Contacts Only | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | Obama isn't going to raise your taxes...it's Bush' fault: Not re- newing the Bush tax cuts will increase the bottom tier rate by 50%

Instead of a plane 72" long, you get a rectangle about 30" by 36" with the legs folded inside. It unfolds to a 30" x 72" surface. Nifty! --Winston

Here's the post: An axle, 2 wheels - much better than 1 - and some wood. 1x6 1x6 -- -- ww | | | | ww ww | |___| | ww ww | | | | ww ==================== < axle ww | |___| | ww ww -- -- ww ww ^^^ ww 2x4 2 pieces of 1x6 7" long sandwiching a 5 1/2" long 2x4, an axle through the "sandwich" and wheels on the axle. Carpeting is glued to the 1x6 such that the table jams into the space between the 2 1x6 pieces. The carpeting prevents marking the table, as well as gripping it. Another piece of 1x6 (not shown) across the end of the "sandwich" so that you have a pocket into which one corner of the table is placed. If you have different thicknesses to move, use a loose piece of carpet to shim for the thinner table(s), and size the sandwich + glued on carpet to "grab" the thickest table fairly firmly. Works fine, as long as you push to move. If you try to pull, you may pull the table out of the pocket - you'd need straps to hold the wheel assembly on the table while pulling. By the way, the same idea (without wheels) works great for holding a door upright with the long edge on the floor in the pocket at one corner and the short edge perpendicular to the floor. Used for planing the long edge/cutting notches for hinges, that sort of thing. For that use, a 3' long 2x4 is used in place of the wheels and axle to provide lateral stability. Ed |
