550 F2 started!

Because they essentially just used an interference fit with the bolts, they used a threaded bolt and just forced it into the wood, this created it's own thread as it got pulled in. This was fine BUT the hole I drilled to accept the old bolts was ever so slightly bigger than the B&D hole, I think they used imperial drill sizes and I used metric. So the bolts were ok until you went to tighten them and then they started to spin. Feeling that eventually the top would come off I decided to devise a new way of securing the bolts so I enlarged the area around the bolt hole with a hole cutter so a 8mm shouldered nut would sink into the wood and not get in the way. Turned out that worked ok BUT the bolt head underneath now fouled the winding mechanism. It stopped it going back as far as it used to. I should in hindsight have copied the same style of bolts as B&D used, they were a mix of domed headed bolts and countersunk bolts, it's the countersunk ones that I didn't copy, they sink into the brackets and keep out of the way allowing the back panel to slide back further.
New bolts ordered, countersunk ones.
Also the new low level feet didn't fit, the head (the part that sits against the floor) was too big to fit inside the gap in the flip out feet (high level), I need to see if I can trim the head size down so they fit inside the gap as the high level feet fold up. It's 80% done, it's just not there yet, looks really nice though.

I know exactly what you're describing but could you not have employedsome roofing washers to take that slack up and dig into the timber top in a more appropriate way and not slip?
Just a thought.........

surely something like the above might sort it if its the issue that Im thinking you have.
If nothing else its been a great sideline project and it going to be mega when its done! ;) :)
Oddjob:
Wrong sort of issue Roo. It was TBH a bad idea of B&D and clearly done for cost purposes. The mod I'm doing will improve it's robustness and should outlast the life of the workmate. Like all things though it can be a bit trial and error.
Laverdaroo:
My bad bud, I have no doubt it'llbe the best workmate out there once its done Ken, eagerly awaiting the press launch if I'm honest.
