Omega drills

[rayf6604]

Has anyone else found that the 15/32 drill size for the top half of the Omega to be too big? There's always too much play either side of the tube. Has anyone found the what the optimum size is?

Nope, seems to be fine with me Ray, not saying that the tube is too small for the drill, but issues such as this can be caused by a blunt drill. It can also be caused by a drill bit out of tolerance.

Same here Ray I haven't had any problem with the 15/32 drill.

15/32" works OK for me too.

 

[bellringer]

15/32 fine for me have you checked it is a 15/32 and not a metric equivalent

I have drilled three this morning with no problems at all. The bit I use came from TR.

I haven't had problems at all with drill size... tube/fitting size I have whereby the fittings are easily pushed in by hand.

I have checked all the ones I have Paul and some of the barrel ends (posting end, not nib end) can be pushed in by hand (some could be pulled back out again by hand but some needed a tap with a punch) but all the other fittings are a good fit. I would not say they were a loose fit but the tolerance is not as tight as the other components. (on the ones I have)

Thats what I mean Walter. I've had to put a touch of ca on them just to make sure they don't get pulled out easily which I don't like doing

 

[Walter]

An alternative to CA, if you know the component is going to be a loose fit before you start making the pen is to slide a transfer punch into the tube and then centre punch the tube near the end to provide a little more grip for the part. Don't whack it too hard or you will have trouble getting the transfer punch back out.

Thats a good tip, thanks Walter.

That is an excellent tip Walter and not just for Omega's, but for any pen where the component is going to be a loose fit

Oh well must be just me then. I drilled a couple more after I did this post and the tolerance was okay. My drills say 15/32 on them so not a metric equivalent as far as I can tell.

Just so you all know. For the next batch of OMEGA I have asked for the posting end to be enlarged by 0.2mm to make it tighter

 

[Penpal]

Question answered in fine style many great thoughts thanks.

You could try a 29/64" drill which is .4513" compared to 15/32"which is .4687"

That's too small for the top cap.

I have a cheap chinese 115 pce drill set, 3 letter drills are the same size, the metric one are a combination of metric and imperial and somthing else.
