Hi all,

I am looking for a involute #7 gear cutter;

14.5 PA

32 DP

14 -16 Teeth

Anyone have one for sale or know of a UK supplier, I have tried a number of options but losing heart with the UK, it all seems to be in the US, but not all suppliers deliver small items overseas. I have kept an eye on Ebay but no luck yet.

Many thanks

Steve

Hi,

Google in CTC tools . I think they are in Hong Kong. I bought a 1 module set a few years ago for about 100.00 dollars . They also sell individual cutters .

I don't think CTC do imperial DP cutters

Tracy tools would be your best bet, they don't show their range of cutters on their site so e-mail them what you want.

RDG do what you want but looks to be out of stock at the moment

The reason you are getting more results in the US is they still mostly use imperial so DP is the norm, in the UK metric has become the prefered type in industry so you are less likely to find imperial cutters except for specialist suppliers who still do what we tend to want as model engineers

Thanks Mark and Jason.

If I was making both sets of gears from scratch then I would have used Module sizes and 20 pa, however, or unfortunately, the gear I need to make has to mesh with a 32DP, 14.5 pa, which then meshes with more gears so I am stuck for a simple solution.

I have had some success and would like to share this with others who have similar resourcing issues. I contacted a Company called CR Tools in Sheffield who make various tools and they may be able to help, speaking with the chap there, I might get a 40mm OD with 16mm ID with the 32DP 14.5 pa made for a very reasonable sum. (here we go, mixing imperial with metric again- the model makers conundrum!)

If I get a cutter from CR I will post here to advise others on the forum.

Many Thanks

Steve
