Well the mill was delivered today, they used a boom truck placing the mill onto a 1" plate after removing the feet off of it for clearance and completed the install in 5 1/2 hours.

I never worried about it the apron gears turn so slowly a squirt from an oil can once in a while does the job.

Thanks Pete, much appreciated!  What do you reckon to the saddle oil level?

The high-lever will move easily when the machine is cold and be tight when the machine is warm/hot. It's a known issue, the plastic gear grows and binds on the pinion behind. The drawing was revised to make the gear 10 thou smaller to give some extra clearance bt I think the main problem is that the plastic used (some obscure stuff called Technyl A90 that you can't get any more) absorbs oil over time.

I've made a few sets of those plastic gears now for people. I made them from Delrin which is not only stronger but is very resistant to oils.

Thanks Pete,

I did just what you suggested: I undid the four screws and rotated the cover around the speed lever - job done.  Thanks again.
I have a few more questions now, though.......

I changed all the oils as per the manual.  Messy business!  Nowhere in my manual does it mention the sight glass for the headstock oil level behind the rear shear.  I only found it after I had the top cover off, by dipping the oil level to the rear of the cavity.  The gearbox oil change was fine.  But the apron....there is a filler plug and a sight glass, which was empty.  When I unscrewed it a trickle of fairly dirty oil came out.  I flushed the apron with thin oil and then refilled with ISO 68 - most of which ran out of the rear of the apron, leaving the sight glass once more empty! Am I missing a plug somewhere?

The High Speed - Low Speed change lever is temperamental - sometimes it moves smoothly and others is is a pig to shift. I know it has to align with two sets of gear teeth, but is this normal?

Many thanks again for any answers,
John

 :clap: Hi Matthew you were right I had to turn the seized head through 180 degrees and then drive out the seized pin.
But we got there many thanks for your help.   

best wishes

Hi John.

The speed control lever has a nut on the end of the shaft underneath. Remove that nut and the lever will pull out upwards. You might have to release the speed adjuster nuts to effect this, or at least to put it back. Mind you don't lose the spring and plunger when you pull the lever out.

Four bolts hold the top plate down. It's flat underneath so you can actually undo the bolts and spin it out of the way without removing the lever. It might be stuck down with gasket sealer.

Hello All,
I don't want to hijack David's thread, but I have acquired a Synchro 280 so am after any information. I have the Denford manual - which is not over informative!  In the thread there is talk of removing the top cover - is this just held with the four cap head screws? I take it the speed control lever comes off with the cover.  Also, is there information on the metric conversion, with a pitch table?
David, you have a pm
Edited to add: I'm on the Denford website and trawling through the mine of information there.

Many thanks,
John
