Brieley DB25 Drill grinder

Just dragged a Breiley DB25 drill grinder out of retirement and put it somewhere handy so it can be used.

However after a clean up and a quick play I realised why it had been put into retirement in that I can't get a decent grind out of it. I have the book and setting gauge and followed this precisely but there is never enough back clearance and it rubs on the heel.

After watching carefully how it operates I'm wondering if it's timed correctly ? There are 3 gears in the drive to the chuck. The first is only on the handle and could go anywhere. The second which is half the tooth count of the one on the chuck spindle carries the cam and lever to rock it. Everything on this is keyed or pinned so the cam and lever can only go on one way.

What can alter though is the timing between the last two gears. At the moment when the chuck is in the setting position, i.e., pawl in the green slot at the top the cam is at it's lowest point at 3 o'clock looking from the chuck end which seems right.

Later on tonight I'll get some photos but would appreciate anyone who has one of these to snap me a couple of pics of the cam, chuck area and would be nice to see one inside the gear case. The gear case can be removed without affecting the timing.

Mine is the early model where the Clearance Relief Arm, No#3 is a pull out lever on the cam follower and not a disk behind the chuck.

Panic over.

After seeing some you tube video's that showed the setting gauge at 90 degrees to the drill, mine at about 45 degrees pointing towards the wheel so all setting lengths were over long.

Then stripped the gear train down and in the absence of any marks on the gears reassembled it with the chuck locked with the pawn and the index pins and cotters on the can wheel in a vertical line, mine were about a couple of teeth out, all is now working
