Herbert High Speed Bench Drill restoration
After owning a cheap pedestal drill and not being happy with it I set about getting a bench drill like the Waldown NH-3. I missed quite a few at auction but I did find this drill close to home. The machine is an Alfred Herbert "B" type bench drill that has a collet chuck and a speed range from 3000 to18000 rpm. The motor is a three phase two pole unit with special balancing and run at 2850 rpm. The drive pulleys are crowned and suit a flat belt. I sold the Chinese drill and am now restoring the Herbert to include new electrics and a single phase to three phase VSD. It has taken a few months to start but I am underway now.

Hi,
I recently brought the same drill but with a 3 axis drilling jig. It only has the intermediate speed pulley so will be interested to see any pictures/measurements of your pulley system. Hopefully will collect the drill when back in Sydney in a couple weeks.
Will watch your restoration with interest.

I have the same drill, it's in almost perfect condition. All I needed to get was a chuck key. I think even the globe still worked. All I was missing was the knob for the switch and any spare pulleys. Once you drill a 1/8" hole on this girl in to a piece of tool steel you will wonder why you ever bother using any other drill.
Oh I miss quality tools like Herbert made?

Progress report and spare parts
So to progress,
Finding spare parts for Herbert drills is easy, you just contact the Paul and in a few emails, you will have hat you need. For the Type 'B' virtually every part can be purchased. I will caution parts are not cheap so you have to remind yourself that this is a machine that would cost at least $10k if it was new and in today's money. [email protected] is the email to get parts and prices and advice for your Herbert drill project.
Disassembly - the drill is totally in bits now and the 50 year old dry grease as been cleaned out of the bearings. Things to watch for are left and right hand threads holding bits in place, hidden pins holding things in place and being organised. I have used zip lock bags to store the sub assemblies. There is no rust in mine and little if any wear so the pin spanners I made worked. Kerosene and WD-40 were used as cleaners.
Body work and paint - my secret recipe of car cutting compound, nylon scourer and elbow grease. The original is still good
Electrics -I have a Powerflex 4M single phase in, three phase out VSD ready to use, all wiring will be new
Things to buy, I have to get some low temp,high speed grease, this is because at 18000rpm it will need it. I am using SKF LGLT-2 which I can get near home.
As I clean I will photo parts for the thread. hopefullyunderside of the drill attached

Hi,
Thanks for the parts list. Do you have the whole document as I also have the Type V bench drill as well as the type B and it would be interesting to see the whole thing. Did you price any new pulleys or belts for the type B when you were talking to Herbert as I don't have any belts and only the intermediate pulley.
Thanks
Mark

Parts list and pricing
Hello MarkGray,
If you send an email to this address [email protected]
the good folk at Herbert will price things for you. The medium pulley for the Type B was GBP98 and the small one is GBP80 when I priced them.
I do not have the compete book, I am sure if you ask Herbert they may be able to scan that section for you,
bet regards mgtoolmaker

Hello from Ukraine.
Hello from Ukraine.
To be continued?
I am interested in the details, detailed photos.
Yesterday bought this machine.
Special need in it, but I liked it.
A lot of problems.
The main problem - there is no spindle.
English I do not know - I write through the translator.
I hope for your understanding.
What is there for engine costs - speed and power?
And interests - in what year these machines were produced?
