Picture on the left the Unimat dividing head stripped and cleaned preparing for necessary improvements.

Center picture a mounting plate made from 10 mm aluminum milled all round and a spring loaded locking handle fitted. This locking handle started its life as a locking handle on a quick change lathe gear box.

Picture on the top right just a different view of the locking mechanism.

Picture left top a shaft made and press fitted in to the original 48 teeth indexing plate . This plate  was originally supplied with the Unimat dividing head.

Center picture the gear that will be used for the next 32 teeth gear cutting job mounted on the new extension shaft , the biggest gear I will be able to cut will be 100 mm in diameter.

Picture top right hand side the spacers and and cap made we are now ready to copy the gear fitted on the extended shaft.

Picture top left found an old cast iron pulley Machined it to the right diameter and 22 mm tick so I can rill two sets of holes on the one side 30 Holes and on the opposite side 40 holes so I will be able to use it to make two gears for my # 1 lathe.

The max diameter of fraction plate it will take in its current set up is 58.5 mm in diameter . Although I could make a spacer between the main body and the bracket for the spring loaded latch , to take a bigger fraction plate.

Picture top left the Fraction plate marked and drilled 30 holes on the circumference for a 30 teeth gear.

The second row of 20 holes drilled in the Fraction plate so now we have the capability of 48,30 and 20 teeth.

Picture top right hand using the fraction plate, to make 2 only 30 teeth gears I gave it extra length so ones the teethes are cut I will part the two gears.

 Changes to the dividing head Feb 2021.

A 35 hole fraction plate made for the next gear on my Chinese lathe so on the simple Unimat dividing head  we have an option of 20-30-35 teeth I also made a spacer between the main body and the spring loaded locking handle to take the bigger plate.

Changes made to the dividing head . March 2021.

Above pictures key way cut in the bottom of the base plate and  base plate  cut in half , 10 mm keys fitted in the bottom slot. All assembled and fitted on the milling machine, next step will be to make a longer mandrill this will give me more room to maneuver .This alteration also gives me an extra 20 mm in diameter.

Picture top left a new arbor made to give more space when cutting a gear , with the original arbor laying below the new arbor on the mill table to compare between the two arbor's. Center picture clamping nut made and fitted to the arbor , as shown in the right hand side top picture.

Picture top left a lock nut made and fitted.

Center picture making a 40 teeth gear for my change gear collection , using my new arbor. Trying out Bronze this time .

Picture top right the finished product two Bronze 40 teeth gears

Some more alterations to the dividing head to make it more versatile as can be seen in this set of pictures.

An adjustable holding bracket made to use the spring loaded handle 90 degrees from its original position and be come more user friendly and adaptable .

Pictures top right hand corner using the new set up to cut a 75 teeth gear for the # 1 Lathe.

Changes to the dividing head. April 2021.

Picture top left the worm shaft and housing made and temporary fitted to the original dividing head and this lines up nicely.

Center picture a bush made and fitted to the worm wheel , The worm and worm wheel are left over of an faulty gate Motor .It will be fitted to  the dividing head main shaft.

Picture right hand top front plate the edge machined down 45 degrees to make room for the worm , clamped to the mini pallet made previously.

worm and worm wheel temporary fitted to see if it will line up .

Center picture machined 8 mm flat sides on the worm shaft , the handle can slide on those flats so that the pointer can be positioned for the correct fraction plates, with the correct number of holes , for what ever division I want to make.

Picture top right hand s1de , the center hub made and temporary fitted with a fraction plate fitted in place simply to work out how to fit the sector arms.

Top left the dividing head with the fraction plates carrier fitted.

The plate carrier and fraction plate fitted. I now have plates with 15,17,18,19,20,21,23,24,27,28,29.31.33,45,47,49,55,60,75,holes, This should give me a good range of gears I can produce.

Above picture dividing head assembled and could be used as is, but the one thing missing are the sector arms.

Picture top right roughly machined sector arm a sturdy 6mm washer made and fitted to the operating handle.

The two sector arms made and fitted , a locking screw fitted to the sector arms, bevel machined to one of the sector arms.

Dividing head in action for the first time making a 85 teeth gear.

Cutting a 85 teeth gear using the latest version of my dividing head , for this gear I use an 60 hole plate and for every teeth I move the handle 24 holes, the sector arms are also working satisfactory.
