Elliot 10 inch shaper motor pulley

Hello,

I have just acquired an Elliot 10m which is missing the motor pulley. Does anyone know the dimensions or have any kind of drawing of it? Also does anyone know the type of belt that it used?

Thanks in advance.

David.

Came across a user manual but apart from seeing that it is a vee belt no sizes.

Do you know the size of the pulley on the shaper and the motor speed?

[Brian WoodParticipant @brianwood45127]

Hello David,

The original 3 phase motor of 3/4 hp has a shaft speed of 1140 rpm. The two step pulley sizes ffrom the motor to the double pulley and clutch unit are 117 and 92 mm respectively. The belt in the next vee size up from A, it is a broader belt than A but I'm sorry I don't know the letter size that equates.

Regards Brian

Mine broke on my 7 inch model, stress fracture, so I made another

The original was aluminium cast, thin and springy to squeeze the belt, which is like a car fan belt

I would find a belt to fit your upper pulleys, then make a replacement pulley to fit the belt for your motor

So the two measurements I would be after are the length of the fanbelt and the inner bottom diameter of the new pulley

The 3 phase motor on mine (which I modified to run on single phase) is/was slower than Brian's at a rated about 960 rpm and the nine and seven sixteenths diameter big pulley takes a vee belt16 mm wide at it's widest. Colin

Many thanks to all

The (I assume original) three phase motor is still fitted. I will have a look to see what speed it is. I think I have enough information to proceed although in what time frame I'm not sure.

The link to the manual was a huge bonus.

Thanks again.

David.

If you would like a printed copy of the manual PM me your address. I have 2, but no longer have a 10M, no longer having work for it. They are great machines, but I think Brian's has a non-standard motor as they are usually around 900 rpm.

This will enable me to lose a tiny part of the mass of bumph which is too good to throw away!

It is much clearer than the NEMES copy in the link.

I think my 7 inch has the original motor and I only use it at the slowest setting, which is plenty fast enough

At any other setting it would just be too fast and go walkies across the garage

Hello David,

Just to complete the story from my end. My Elliot 10 came to me more than 25 years ago and I re-motored it with a single phase 1450 rpm 3/4 hp motor. To get the input speed down to the equivalent of a 900 rpm motor I mounted an intermediate shaft at the back on plummer blocks with suitable sized pulleys and then drove the machine through that instead.

It has worked very well for me; in all other respects the machine is as Elliot sent it out.

One tip I will pass on as the handbook makes no reference to it at all and that is to turn the entire tool holder and clapper box unit upside down to be able to extract it from the ram. You could puzzle over that for ages otherwise!

Regards Brian

Power shapers, and power hacksaws for that matter, really must be bolted down. Even smaller types, like the Elliot 10 M, are quite capable of going through a shed wall given the chance. If unrestrained the big boys can get through proper old style industrial building walls with little trouble. The consequences of running one of the big 20" or 24" stroke hydraulic drive versions at top speed and long stroke setting without properly bolting down don't really bear thinking about.

The graceful, near silent, operation of a power shaper tends to obscure just how lethal they can be. Only machine in my workshop that I'd seriously consider putting modern style access control guarding round. If I ever had other folk sharing the shop on a regular basis it would get guarded.

Clive.

hi David

on my 10 m the vee belt is an old Dawson speedona i can just make out size B 38 code T on the label measuring with callipers its a little over 16mm width probably swollen with age and oil.

the small pulley is cast iron approx 50mm thick and vee ways measure approx 117mm large and 92 small at the largest diameter hope this is of help
