I`ve got an Asquith Archdale drill grinder.Originally these things were Archdale and Asquith got added as the companies went down and the names were bought up.In fact there might even be a Stavely in the name as well. Crack Advanced Jpeg Compressor 2010. These machines were 3' capacity.Had a two jaw chuck with three sets of jaw inserts for the three ranges of drill diameter they covered.Stone was carborundum ring shaped lead bonded to an metal backplate.Stone would be about 9' od x 4' id x 1.1/2' thick approx.ID is important.The machine works in rather an unusual fashion,the chuck/workhead spins in a true rotary plane and the grinding stone spins and oscillates side to side and out and in.The chuck is mechanically driven from the grinding spindle. The id of the grindstone is important as if it was bigger it would not reach across the whole drill edge. The drill is set for grinding by setting the chuck at a certain position,putting the drill in the chuck and forward until the point of the drill is nearly touching a swing down stop and the cutting edge is lined up with the top face of the stop.All done according to the operator book which I have. Unfortunately the results are less than perfect and I don`t know why.The edge looks good but it undercuts the chisel edge,looks like point thinning very badly done,but it`s not meant to do point thinning.

I`ve spoken to someone else with one of these machines,I was suspecting that someone had dismantled mine at one time and had mistimed it when they put it back together.But no,this guy had the same problem with his.HIs worked perfectly when used by an old guy who worked for him,old guy passed on and nobody can get the drill to grind a decent point. So it`s a setting problem,but what. Tyrone are you there? I'm not sure I can help you much Mark.

I've done a fair bit of drill grinding but always on a ' Herbert Hunt ' drill grinder. They were very popular and a good little machine, ' Churchill's' took over the rights from ' Hunts ' and made them until the 1980's I think. I've worked on old ones and new ones and they seem to operate in a similar fashion to the one you mention. A spindle holds the drill and rotates at the same time as moving in and out.

The grinding wheel sort of oscilates as it feed accross the face of the drill. On the one I used you could do 2, 3 or 4 flute drills, flat bottom, fish tails, you name it. The only light I can throw on the problem is this- on the machine I used you slid the drill through a guide bush in a bracket bolted to the grinder. This bracket had a little spring loaded setting device that came out sideways, you married up the edge of the drill to the edge of the device to get your starting position. If you were only taking small amounts off the point this was fine, however if the drill was broken and you had to take off a lot ( 3/4' lets say ) you had to reset the edge of the drill to the setting device as you went otherwise you could get a similar effect to the one you describe.

Sorry not to be of more help, a photo of the drill points would help. Regards Tyrone. Tyrone,sorry for delay in replying,been away all week.The work spindle on the Archdale only rotates,the stone goes side to side and out and in,very strange.This name was taken over by Stavely or Asquith and whoever owns it now knows absolutely nothing.
