About 15 years ago when visiting a local scrap merchant which also dealt in machine tools I came across 2 Herbert Type B machines for sale at ridiculously low prices. Unable to resist a bargain, I think that I purchased both for about a tenner for the two, I took them home with the intention of restoring them & putting them to good use in the workshop. However, as happened with a lot of things, work & family pressures deflected me from my course & it is only now, after retiring, that I can see my way clear to doing something about them in the coming weeks or months.

I have seen in the albums that member Ian Parkin posted in 2015 when he uploaded a series of photos of the restoration of a Pollard 9FX machine which appears to be identical in every way to the Herbert Type B. I believe that it was also re-badged & sold under the name plate of several other manufacturers. Has anyone else either got a similar machine or has had one in the past? I am interested in the work that Ian did to his machine but cannot find any forum posting devoted to it. I have Emailed today but being a Sunday I don’t expect to hear from them immediately.

Any information will be gratefully received.

Kind regards,

Hi Ian,

That was quick. I’m primarily interested in the electrics. I guess that that the original components are no longer available & probably less than desirable in this modern age. Did you use an inverter? I have a 3 phase connection available for it in the workshop so single to 3 phase isn’t an issue. Where did you obtain the switchgear etc from please? Also sources for the flat belts etc.

Kind regards,

Mine had a single phase motor on but i put a small 3 phase on and an inverter for the variable speed facility.

Switchgear is a mains isolator and start /stop button and pot for speed. Easily available from any electrical shop

Belts are easily available just search for flat belts 12mm wide from memory

I had to make the 2 bigger pulleys they always seem to be missing. So with these you get 6 speed variable speed from 10hz to 100 hp. It works well at 18,000 rpm

Thanks Ian,

Can you give me the diameters of the pulleys please? I believe that I am missing the bigger ones also.

Hi Chaps,

I want to order belts for my twin Herbert B's.

Does anyone know the belt length? Mine came fitted with abrasive belts (ewww) like you get on a Dynafile.

Hi Wilson,

Although its nearly 2 years since creating the post, my machines are not yet fully refurbed. I have so far disassembled both, cleaned, paint-stripped, filled & repainted both sets of castings. However, I am yet to reassemble both machines & get them running. Consequently, I am approaching the stage where I will be investigating the length of belts that will be needed.

If you have the machines complete then calculating the required belt length will not be difficult. As a starting point you could use the formula of: - Belt length = (0.5 x motor pulley circumference) + (0.5 x driven pulley circumference) + (2.0 x center distance) as a starting point. Also bear in mind that you may need more than one belt length to allow the use of all the different pulleys available.

Kind regards,
