They come pre-assembled- interesting that the original mills had straight cut gears (as shown on the original link) and they've moved them. Can't but help that the end-float on the "upper" mill has lead to an excessive amount of back-lash on the gears. It's hardly surprising they've gone. Now if you could find a suitable sized washer you could put one under the circlip to push the gears closer together.
BTW I've e-mailed Hambleton Bard (who distribute the mill) to ask them if replacement parts are available. Partly out of altruism and partly as a concerned owner I'd be interested to know.

Re: Problems with Bulldog mil
Looking at the design of the gears, is there not some spring or other means of automatically pulling/pushing the bevelled gears axially towards each other, so that this movement would take up slack between teeth as the roller (and therefore gear) gap was widened?
I'm only guessing as i've never seen one in the flesh, but it seems a likely reason for going with bevelled, rather than straight or spiral toothed gears. Which was then defeated by flour/grain packing around the end of the roller...

Re: Problems with Bulldog mil
I think if those gears had been put on the other way round and a spacer/washer to pack out the space all would be good.
I think hand cranking has warn them because gear movement and lack of bushes/washers.
Then when super-duper-drill was fitted, we got a spin-stripping-tastic of those already half knackered gears.
Just to reiterate, no fault of owner, but faulty chineese worker half a sleep and over worked. And poor quality assurance,

Re: Problems with Bulldog mil
Thanks for the help guys - if the gears are replaceable it can be repaired
Re: Problems with Bulldog mil
Hambleton Bard says any mill less than a year old can have free gear replacements and replacement gear sets are available....

Re: Problems with Bulldog mil
I was looking around last night, this was one of the places I ended up.
http://www.motionco.co.uk/spur-gears-32 ... 33_24.html
But not knowing any of the dimentions of the gears, it was a guessing game. But anyhow it good that Benb has contacted HB an of course The good news that they are available.
But on another note I really should read previous post properly. Then maybe I will not be repeating what has been said before
Anyhow cheers to a good result
