[NKmachinist]

Hi All, looking for some guidance to source Gits bros oiling cup used in Derbyshire magnum or elect lathe? I have taken some pics, looked around on eBay and tried to understand what NPT is to compare with my thread size. Still very lost. TIA..

Thread size is 6.6 mm, total length is 15.34 mm

Check Leonard Industrial Supply. Haven't ordered from them yet but seem to be a good source for gits and others.

Hi, I am not able to understand the sizing chart. The thread OD is 6.6mm. What will be the close enough size?

what makes you think it's not imperial that's close to 1/4"

Gits oilers in that style are available in 1/4-32 thread.
Need to check the pitch of that thread.

Seems to be an odd size; we don't work in mm here, as stated above, we need mor info on thread pitch,

I understand what you are saying. That’s the reason why I am stuck. I was able to take measurements using a caliper and got the readings in mm. Also the reason why I am not able the follow the sizing chart..

I would think it’s imperial as this is an out and out American lathe.. sorry for giving measurements in mm. That’s what I learnt in school and not able to quite understand the imperial system..

Many old english lathes were imperial.. and your 6.63 falls around the .25" .261" it is 10 thou over, but it might be tapered so it doesn't leak.. I don't know.. if it's .25 at the bottom and .261 at the top then it probably is slightly tapered.
