Looks like a machine with potential.

I like the T-Slot cross slide. - a standard item or an addition?
Is there a set of change gears for driving the lead screw - like on the Model C southbend/hercus/boxford etc

Re the extra key hole(s) on the chuck - are there multiple extra key holes? If so I'd SPECULATE (dangerous I know) they are a mechanism to adjust the run-out of the 3 jaw chuck.

Now a curiosity question - on the photograph of the headstock, at the chuck end, there is a lever with what appear to be 2 indent positions - the lever is in the lower position - what is the function of this lever?

Looking forward to more definitive answers.

I hope you enjoy the new acquisition.

David,
Not wishing to steal jackaroo's thunder, but the headstock lever you mention is the back gear selector. Jackaroo if the need arises as you get into the lathe, I do have some spare bits that are wear prone, original Myford. PM if required. Alan.

Hi David,

Yeah that chuck has 3 additional holes next to the conventional ones like in that photo.

I looked though the manual the t-slot looks to be standard. There are a set of 9 gears that comes with the lathe for thread cutting well and that seems to be complete set according to the manual.

It also has 4" Burnerd chuck (on the floor) without the outside jaws however I scored 2 sets for the outside jaws with the same patch number, which is good however the backplate for this chuck doesnt seem to be original (ie probably fabricated) and it doesnt fit into the collard spindle all the way.

The level on the right hand side is "backgear level". I am not too sure ho it works yet. I think when it is on the bottom hole it has direct drive. When its on the top hole it is on reduction speed just like Hi/Lo gear on 4x4 gearbox. I am not too sure it seems to the spindle when I put on the top hole.

ps: the gear bore size is 5/8". I found a full set of gears change for hercus from a friend but it doesnt fit (bore size is 14mm) I think its for hercus 260 or somehting like that he told me.

Hi Alan,

pm sent.

Cheers

nice Myford you have there Jackaroo Myford are still in business and still carry replacement parts from from way back. you have a good machine as Havinago mentioned the T slotted cross slide is very handy and Myford made loads of attachments for that purpose like a universal dividing head so you can cut gears and a milling attachment if you watch Ebay you maybe able to get some of these as they often come up

one thing i have heard that the top speed something like 2000rpm is not sutable for the bearings and should not be used often but this maybe just for the older white metal bearings that melted! yours probrably has babbate bearings (definatly not roller bearings) but still you should look into it and use a good cleen spindle oil in them no used motor oil

have fun with your new lathe and be sure to show us if you make anything

Jackaroo,
Re gears, from memory the Myford is 14.5 deg pressure angle and I think the Hercus is 20 deg. PM received. Alan.

The Myford Gears are 14 1/2 PA same as hercus but 20DP.

Pipeclay,
Thanks for clarification, now to ensure brain cells retain it for future. Alan.

Hi Jackaroo
There is a little hex screw that you have to loosen and a little plate with fingers which you slide to seperate the bull gear from the other gear for the back gears to work. You will need to shorten an allen (hex) key to fit as the space is tight.
Darrell

Thanks Darrell,

I saw that hex bolt and thought that might be it but I havent looked at it closely yet.

Here are some of the gears plus cutting bits that came with it and some I bought elsewhere. I think the gear are for metric cuttings as each gear has M3, M4 tamped on them.



here are the hercus gears I got from my friend.
Jackaroo,

Hi Jackaroo,

I've learnt something which is great - a back-gear arrangement exists and some starting points on how to use it!

One thing - in that interesting tool box of parts - do I spy a 1-2" micrometer?? - please rescue it from all those sharp edges!

The box of goodies looks useful.

As new_guy90 said - looking forward to seeing where the future takes you and your lathe

kind regards

David

David@ That 1-2" micrometer is missing a ratchet knob.

Darell@ I undo the screw and moved that latch out and the gear seems is working for that level. THANK YOU

Oops -

still a shame to see it put aside - that old saying one man's treasure ...

All the possibilities in a tool box of parts - so much potential - right angle plate, chuck, tools, bits I don't recognise .... looks like a great buy

I collect bits and pieces and have plans but family and life keep me well occupied.

My plan to move the lathe into its working position in the shed has taken over a month now as Tax had to be done, the hay at my MIL place needed to be carted, and now the bathroom is being renovated (by someone else although I have little tidying up jobs around the edges). Going to work pays but it does muck up getting to the interesting things!

All the best with the lathe

Hi Dave,

Some of the cutting bits are mine, including the P&N T-handle and that M&W micrometer. I still have 2 keyless drill chucks (one is german, one is British) and a small live centre somewhere...a smaller Moore and Wright micrometer as well which I collected over time from Trash & Treasure market. I need to find them somewhere in one of the boxes when moved house.
