Gears

[cityhick]

Crashed my Logan (powrkraft) lathe. Anyone here able to fix me up. I can get the gears through logan but they aren't cheap.

What DP are they & how many teeth? If I don’t need to buy a cutter I could possibly help out.

The dual gear is 16/32 toorh the single is 40 tooth. Excuse my ignorance but what is DP?

Diametral Pitch

In addition to knowing the tooth count, one needs to know the diametral pitch of the gears so that they all mesh properly.

Edit: I "think" Logan gears are 16DP, at least that's what I see on a MrPete video where he cuts a new one. I don't own a Logan though, so cannot verify this firsthand.

No problem....tell me the outside diameter of each gear & approximent tooth depth. I can calculate from that information.

 

[cityhick]

40 tooth... 2.105 diameter x.108 tooth depth
32 tooth... 1.701 diameter x .108 tooth depth
16 tooth... .900 diameter x .108 tooth depth

I can send the gears to you whoever can make them to copy also

Also, you need to know the pressure angle.

The gears in your picture appeared to be 24 DP, of which I have several sizes in both 14 1/2 & 20 PA. With your information I believe they are 20 DP which I do not have cutters for.
Hopefully someone with the proper cutters will chime in.
BTW, out of curiosity, what does Logan want for the gears?

 

[cityhick]

$218 for the 32/16 and $108 for the 40
