Thread: my first lathe.
11/12/2019 17:15:55

well all i know is it came already mounted on the lathe and as i said previously the original oem one has been put back on

10/12/2019 18:44:53

im a great believer in just having a go,you learn from your mistakes,well some people do lol

many thanks fella's,ive ordered a set of hhs tools to get me started and also a small round bar of bronze to have a play with.

just how sharp do the tools need to be? do they require further honing?

not a problem if they do,i still have my wet stones from my cabinet making days,back then i always had a bald patch on my arm as i used the hair to gauge the sharpness lol

Cheers Paul,

I bought a small blank of delrin to have a play at the weekend.

im still not sure what type of tooling to buy, anyone have a link please or a good dealer to buy from please?

08/12/2019 18:58:10

thanks,i will put the original one back on.

auto feed is being used and i will try it with both slides locked .

08/12/2019 15:17:48

nice one cheers,that makes sense.

could someone link to some good quality tooling i can buy please? ive been looking but there's too much choice,whats best?

good old hss or the ones with throw away cutting tips?

08/12/2019 14:39:26

cheers dave for the reply,

i do have the original round tool post,the one in the pic was on it when i bought it,its a quck change type.

the bearings do not appear to have any play,as does the main saddle,the cross feed and tool post gibs were bent out at both ends so i straightened them at work and re adjusted.

what is the larger bolt for in the center on both beds? is that for intially getting the gib strips in the right position?

What sort of tooling are you using Jamie, and is it bang on centre height?

hi,yes the cutter is in the center.for the first few goes i used a rounded tip cutter,sorry i dont know the techical name,then i switched over to this cutter you can see in the pic,i made a much better finish and took finer shavings.i suspect i need to buy some new tooling.

so after looking for a while a hobbymat md65 came up for sale 15 miles away,i went to have a look and bought it.it comes with the milling head attachment and lots of extras such as the slow speed wheels,spare 4 and 3 jaw chucks,a box of collets etc.

i spent a few nights after work cleaning it all up as it had been in a shed for a few years,it has come up very well,i also oiled it and adjusted the gib strips.

so today i spent a few hours having a play and just turned down a bit of steel.

in trying to get a good finishing cut and all seems well except every now and again the tool seems to dig in and leave a faint ring mark.

ive tighten up the beds and that seems to have helped but anymore and the beds are too tight to move smoothly.also the lathe is not bolted down.

any thoughts?

yes i know its in the kitchen,being single has its rewards laugh

But I recommend focussing on what exactly is essential in the way of 'tight tolerances'. In practice, when making a simple bearing, I doubt many of us would insist on a machine capable of working to tight tolerances in the sense used in manufacturing were it's important to make parts interchangeable.

A slightly different technique considerably reduces the need for sooper-dooper machinery. Parts aren't reproduced from their measurements directly. For example, this bearing could be made by first drilling a hole slightly undersize through bronze, brass or oilite rod and then carefully boring the hole out to size. Likewise the outer diameter would be turned slightly oversize, and then carefully removing excess metal until the part fits into the turntable. In both cases 'size' is judged by reference to the shaft it's intended to fit, and the hole in the turntable. There's no requirement for lathe's dials to be spot on. When working by comparison, any lathe in reasonable condition will do the job.

cheers dave,

thats basically my thoughts on how to do it .

just to clear the is or isn't it an oilites bearing up here's a video of myself putting the oil back in them under vaccum.

you can see the air being removed from the bearings so the oil can get into the pours.

many thanks for your replies so far

Rather than spend big money on a lathe, I would spend it on a quality turntable. A Sony from the 1970's isn't exactly top of the range Hi Fi.

Andrew.

Andrew you clearly no nothing about turntables! Especially certain Sony models from that era.

rather than post a pompous comment like that why not just recommended a lathe for read up about.

the bearings are actually in rather good condition, they are definitely oilites as I’ve just re charged them with oil under vacuum.

the modifications I’d like to do are hopefully an improvement over the old ones, using better suited modern materials .

this won’t be the only job the lathe will be doing, so it won’t be bought just for that.

many thanks to those that have left advice so far.

So any lathe recommendations?

27/11/2019 20:34:54

ah ok,i figured the japanese didnt use imperial

27/11/2019 20:18:26

hi,

the turntables dates from 1974 and is a high end example,no spare parts are not available anymore.

the oilites bearings are approx 11mm id and 16mm od,ive checked online a few times and it would seem the size is not a standard stock item,besides theres no fun in just buying off the shelf

27/11/2019 19:11:34

hi,

i would like some advice please on which small lathe (new or old) would be best for making some new bearings for my sony turntable.

i would like to make them in bronze or maybe delrin and also have a go and make the bearing housing in the same also.

could you guys advise on what lathe to go for that will turn to tight tolorences.

i should say im new to lathe work but my job is a steel fabricator.

here are some pics of the original housing and bearings.

thanks in advance.
