550 F2 started!

If no one knows for certain I've got some starters lying around doing nothing, I'll take one apart and let you know.

Did you remove the screw and take out all the insides as well?

Looks to me as 2 smaller washers on the brushes end and the 2 larger on the splined end.

[Laverdaroo]

my only point of reference is a chap on the net taking one to bits from a cb750 which is similar.

From what I think , its small washer, castle-ated washer (one with legs on) on the brush end with the legs facing up, then two shim washers on the bottom and the plastic firbre washer thingy against the end cap so that it doesnt ark against the cover?

Ive tried it together several ways always with the lines on the outside to line up and once done up wont rotate so summuts wrong!
cant get me head round it tbh, proper scratcher!

If you would if you get 5 mate that would be brilliant. Sick of swearing at it and the internet is drawing a blank also. Vheers Ken.

[Laverdaroo]

Stand down mate, managed to sort it had the shims in the wrong order it appears, anyway, fettled and checked and all good so onto the next part for nannying!
Cheers for the offer Ken.

Managed to finally get out this week after being holed up at home with what was quite a nasty stomach bug, been blowing chunks for days but managed to get out today as feeling slightly better. Basically felt sea sick for three days!

Anyway, manned up and been out collecting bits, posting bits, buying bits etc and took a trip down to DJ Engineering at Keynesham near me to pick up the head and barrels after they got decked out on the mill for me.

The gasket surface were far from good so he’s taken 2 thou of both faces for me so hopefully all being well, I’ll have a go at cleaning the cases up with a view to getting the crank and gearbox in this weekend.

Hooray, something going together finally!

Well those look nice Roo.

Good news for me too.

Will finally get round to assembling the workmate so I can do some polishing. Picked this up today.



Finished the alloy braces, painted all the logos and even did the little holes as well. Took me ages.







Just finished painting all the other bits that required it. I'll post a pic of it assembled once it's done. Not sure yet whether to varnish the new worktops or to just leave them as they'll get hammered anyway.

kin wl Ken, thats the swingers mate. Never mind the varnish I was expecting OEM transfer of the 'Rule' down one side, 180 degree angle finder in the middle and associated decals. Get it varnished or at least danish oil it, it'll make it a bit more supple and will dent rather than split when you miss what you're tw*tting

[Laverdaroo]

Besides, that's not the right black, wrong colour code, rookey mistake

The rebuild did not go well. The frame is built but the wood isn't mounted yet, my idea of improving the way it mounted onto the frame just didn't pan out. So more parts on order and try again. Getting a little sick of this now 

[Laverdaroo]

Bloody hell Ken, why did you try to modify it? I thought B&D did quite a good job at the design in the 70's why would you wan to change it?...............stop fiddling with stuff!

[Oddjob]

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.
