Indeed a coincedence, but I used the search function, but could not find anything about this topic so i started my own. Ok good that you van confirm it is 5/16 BSF. I order the right tap nou hopefully

KR, Joost

Ah I did not know that the unc/ unf threads were american

Ok I will try a BSF tap then with 22 threads per inch.

Thanks guys!

Hi Keith,

Thanks for your answer!

No I do not have a thread gauge... M8 is going maybe 1 turn, unc is going two turns and unf stops after 3 turns. So I am coming close. Why do you got so many thread sizes😃?

Diameter is 0.310 inch.

Hi All,

Does anybody knows what thread size the bold in the photo is? (see red circle).

I know what it is not because I purchased these taps and thought it was the right size.. It's not M8, not 5/16 UNC, not 5/16 UNF. (I want to add a handwheel)

Thanks!!!

Mmm that looks like a quick, cheap and easy fix.....

Too bad I already sent it to HPC gears.....

Quote: but it's mine, you can't have it, sorry

Why not? It is only one small plastic gear!

Ok will sent it to HPC and they will see if they can make one.....

Hi All,

I tried the solution from john kennedy 1, but it appeared that the problem of the power cross feed was much more down in the device. See the picture...

The gear that is missing in the picture has one broken tooth. See below:

The diameter is 12.31mm or in inches:

The gear has 30 teeth, and the hole in the middle is 2mm. I tried to find one but without succes sofar. I contacted HPC gears today, so will see if they have one.

Hi John,

yes that seems like a solution for the problem. Maybe I can do that. Thanks a lot for your fast reply!

Hi All,

I actually bought this unit off ebay, which Ziggar is referring to. But it has got an issue. When there is a little bit force on the crew that turns, the gear slips. When I took it apart it appeared that the conical gear on the top is a bit worn out (it is from nylon I think). Does anybody know if there is a spare part out there for this power cross feed?

Thanks for your help!

Kind regards, Joost
