|Thread: What’s the tolerance??|
A lot of ME drawings are not drawn to any one scale or projection and are more a collection of 'scrap views'. Bolt holes may not have the intended thread mentioned, just the centre location.
If your engine was originally serialised in a magazine, then assembly, marking out and lining up was dealt with in the write up. Hughes tells you how to align the engine mounted on the boiler in his book on Minnie, which will work for any traction engine.
Known mistakes are not corrected, the author having 'moved on' to the next project. Omissions from the magazine write up remain omitted from any subsequent drawings. Haining omits the steering gear detail on his 16hp single ploughing engine all you get is the chain drum.
It's all guidelines Bob, just guidelines.
|Thread: Warco WM280V-F Gearbox|
The issue I was thinking about is if the two shaft bores are diverging you may get enough clearance to hammer the righthand gears. I think you ought to talk to Warco and share those photos with them.
Looking at the first photo it appears that the recess for the plate is slanted. Hopefully the shafts are parallel to the mounting surface and the two shafts are parallel to each other.
I'll leave the rest unsaid.
Apologies Barry, I assumed the worst on your gear shifting.

|Thread: TOOL BOXES|
Halfords cheap range (non ball slide) top box I use for milling cutters.
I have 2 blue aussie wheeled tool cabinets from when Bunning were busy wrecking Homebase, my Centec 2A sits on one with the tooling below, tother gets used as metal storage, drill bits etc. Loading was 45kg per drawer if I remember correctly. Homebase still does a Draper one remarkably similar but 100 quid dearer
I have a Clarke ball raced top box which is much better for proper car tools.
It's best to check out the trolley wheels, some are obviously pathetic.
|Thread: My new Sieg SX3.5DZP problem|
Halfords used to do that service.
|Thread: Yipee the F1 is back on|
Wrong sport, that sounds like drag racing
|Thread: TOOLS EXPLAINED BY A DO-IT-YOUR SELFER|
you've done this before haven't you.
|Thread: Inherited Lathes and Milling Machines|
Use the advanced search on ebay and set it for sold items (the prices come up green)
|Thread: Reverse Sewing Machine Motor?|
Wonder if all they do is turn the brush carrier around? I have a 1/4hp brushed motor from the Great War that reverses by rotating the brush carrier.
|Thread: BSA drop down centre stand|
Bet it froze up in the winter
|Thread: Ring rollers|
You need to decide how much un-bent ring you can live with.
Pyramid rolls where the top middle roller drives and bends the metal by pressing it down between 2 fixed rollers leaves a flatish start section. The top roller (which needs to be removable) gives the minimum ring dia
Initial pinch where the metal is clamped between 2 rolls and drives the metal, the third roll moves past their centre to give the bend. The top pinch roller (which needs to be removable) gives the minimum ring dia. This one will roll a true round assuming you cut the length correct and grips the metal better and so slips less.
You can make rings on a sheet roller.
|Thread: West Yorkshire Police|
Some kind people wont let you pull over and cross their lane either.
|Thread: Useful Tapping Drill feature|
No ME tapping drill sizes in my Zeus
|Thread: Change to the Code of Conduct|
A quick look at the trading standards site shows john lewis recalling a bathroom cabinet because the mirror might fall out.
Did john Lewis check them all, No
Did they make them No
However they did recall them, not the maker the seller.
This came out for a no deal Brexit withdrawn doc it may come back if no deal happens anyway at the end of the year.
Jason, I did, it said No problem with linking to UK, European or worldwide suppliers that are bona fide companies who comply with their tax, safety, etc laws This is why I said "Not sure how 'we' or the moderators are supposed to know that a supplier does not conform to UK standards"
And now I see my error with that one, I should have said "their standards without any knowledge of what they might be".

Not sure how 'we' or the moderators are supposed to know that a supplier does not conform to UK standards, have you been supplied with a black list?
We have already been prevented from posting about one unearthed equipment sale from a UK supplier
As this site is now only allowed to post links to UK suppliers who may not export and therefore only a local site for local people our members from abroad may be wondering why they logged in. I suppose the advertisers will not miss them anyway.
|Thread: Buying first lathe|
I assume you can go and see it?
Bed shows wear ridges, the depth needs checking with a feeler gauge & steel rule. Suck your teeth if a 5thou gauge slips underneath and tell him £600
Don't forget it will only swing 7" dia x 20" long, which is just big enough for a Minnie traction engine wheel
|Thread: Concrete Garages, Shelving and Catastrophe|
Doesn't that roof get a little damp?
|Thread: Sign Language, Cochlear Implants, Hearing Aids|
Cbebbies 'Something special' Makaton lessons eveyday
