Gear Supplier – special

[Clive BarkerParticipant @clivebarker72854]

Does anyone know where I can get a 27 tooth 16DP steel gear made. 27 teeth is not a stock item. Many thanks.

Pressure angle?

HPC Gears will make one if the above doesn’t fit the bill. Likely need to sit down before asking the price.

[Clive BarkerParticipant @clivebarker72854]

Thank you all for your responses. Dave I don't know how I missed the imperial sizes in the HPC listing. As for pressure angle – I am going to have to get the magnifying glass out! I assume 20deg.

[Pete RimmerParticipant @peterimmer30576]

HPC have a minimum order. I could knock one up for you Clive, if you send me the details. You might have to cut your own keyway.

Is it a Myford change gear?

[JasonBModerator @jasonb]

No minimum with HPC, have a look at their FAQs

And a Myford gear would be 14.5pa

Ok I know you may not like us to poke into youir business but do make sure you really need it. On another forum a couple of months ago a chap went to lots of trouble and expense to get a gear to cut a non-standard thread to approximate a metric thread. It turned out he actually could cut a better thread with the gears he already had.

Hmm, you're right. I checked back a few years and it's been that way a while. I must be remembering it wrong, or confusing with another supplier.

[Clive BarkerParticipant @clivebarker72854]

Thanks Jason & Pete for your replies. It is the idler gear for a Colchester Student Mk1 Norton Gearbox. Using a magnifying glass ruler and protractor it looks like 20deg pressure angle. The HPC off the shelf gear with a sleeve looks like the way to go.
