and definitely keep the drill speed low

If anyone is interested I made one years ago and it has given good service I could email the drawings they come from The Model Engineer and Light machinery Review dated Aug 15th. 1929!!!!.Nothing new under the Sun!!!

surely there are tool suppliers in Italy/?

Could you not test performance with a compressor and variable regulator?

Don’t understand why people insist on using motor oil as a protection against corrosion it’s useless. Use a oil that does not emulsify like tag or hyd oil.

What’s really annoying is that they don’t give you a choice. It’s the take it or leave it attitude.

They are cast in phbronze but not by me they were left to me by a departed friend who was an extraordinary furniture maker with leaning towards chairs. I’ve had them for a while and they are just lumps of metal unless you do something with them. I did temper the blades today and hone them and they work very nicely.

Hi peter, it has both 8 and 10 mm spindles.

More or less finished today just got to temper the blades tomorrow.

Pete, It’s a mikron 92 with a standard head. Bought it for £100 many years ago and overhauled it that was almost a waste of time as couldn’t find anything wrong with it and it’s been working ever since. I mostly cut gears for mechanical instruments (speedometers and rev counters) with it but have got a couple of 20dp hobs so I can generate odd changewheels for the machine itself which I converted to use Myford style wheels.

Roger, It’ll be interesting to see that it could spark a bit of interest as very little out there except cues and small mikron machines like mine ,best of luck..

If you make the GHT stamp holder the stamps are are pushed to one corner of the holder by leaf springs and as usual with GHTs designs it works!!

Couldn’t you use a lapping plate for that?

I bought a set of 1 mm from Pryor a couple of years ago as they assured me that the characters were absolutely central and they are, worth the extra few quid.

BASS 66 nearly all the fasteners I make are for Pre 30s bikes and I screwcut most of them much better looking totally concentric with plain sections etc.

The item attached to the vertical slide is a Changewheel dividing unit which is why you do not get rid of changewheels!!!

+ 1 for that if you haven’t got it you can’t use it and as for changewheels NEVER part with them!

Leather workers use corner and radius cutters Suzi on the repair shop

No definitely not but if it helps over the years I’ve had my hobber I have slowly worked out a change wheel chart based on available change wheels (converted the machine to 20dp Myford type which were cheap as chips then. As you say your fixed ratio is 40 to 1, mine is 16 to 1 so to cut a 10 tooth gear it’s 10 div 16 = 0.625 which I achieve by using a 48 and 30 tooth wheel setup. For some tooth counts compound trains are necessary but I shy away from them unless really necessary. Hope this is some help
