Need to take off the front wheel and don't have a front stand, but I do have plenty of 2x4s. I whipped one together and it seems to be pretty stable but wanted to see if anyone else has done this before I leave it sitting on this thing.
Here's the page from the book, and here's what I bodged together. My rear stand didn't lift high enough for 6 layers of 2x4s, but I'll fix that tomorrow. I also screwed the whole thing together as I was worried about the weight of the bike pushing the pieces apart. Thinking about screwing some eye holes into it too and ratcheting the bike down just to be safe. I guess mostly I'm just worried about supporting the bike from the bottom of the engine as I'm not sure how strong this is.
Oh! standing it by holding the engine on wood, Ok, I can see that working but you have to break the bolts loose before putting it up on it and again doing the final tightening when it is on the floor again. I do not think this is supportive enough without the rear stand for vigorous wrenching or clumsy people going through your work area.
