Can you use metric equivalent drill on an omega

[Paul]

Is the impact too bad on using a metric equivalent drill bit on an omega. I failed to order both drill bits and wondered if an equivalent metric bit would be okay if I can't source an imperial in a local shop.

I do appreciate they are different but wonder if anyone does and more importantly it all works?

Thank you in advance.

Just measure the tubes and select the closest drill bit sometimes the manufacturers stated sizes are not the closest, always measure.

There are some here who will say yes, others maybe, and some say no.

Maybe.

Depends on the wood, and the glue. If you were to use superglue and spalted beech, your chances of success are limited (not zero - limited!). If you were to use a rosewood and epoxy, you have improved your chances. Without reference to a drill bit chart I cant workout how big the nearest metric would be, but again there will be several here who have had failures and never used imperial drills.

Good practice is to use the right size drills. You will be able to get the right size drills from an engineering supplies shop and you will have several hidden away on industrial estates near you.

It's your kit kit, your drills, you do whatever you wanna do init?
You a big boy now make your own decision and don't let anybody tell you any different.

Seriously though If you're really are unsure, choices init?
Wait till you get the right size drill or drill a scrap piece and size it up, it'll fit where it touches and not fit where there's a gap, how's that?

Yep Paul knows he already has the best advise and he knows I am gonna take the pee init?

 

[EStreet]

what's the omega?

 

[paulm]

what's the omega?

Only the best pen in the world.... probably

 

[EStreet]

OK scratch that last one, just looked it up.

Try a 11.9mm or 12mm and a 9.9mm drill bit

 

[EStreet]

also FYI this is the same drill bits used on the baron/sedona class kits.

At risk of getting head chewed off after I have been asking so much about glueing tubes in blanks...If you do drill with an equivalent metric and find the play between the tube and the blank is a more than you hoped, you can always use Gorilla Glue as it gap fills quite nicely.

 

[EStreet]

Two things worthy of note:

A) gorilla glue provides *NO* support when it foams. the foam itself is very weak.
B) The gap difference in the mm I provided is minimal. try 0.021875mm difference.

A good fit is important since even if the gap is filled with a gap filling glue it can cause you out of round problems.

HOWEVER As has been said the stated size of the tube is not necessarily always correct (it is with the Omega) and drill sizes can be variable too.

I find it is always best to measure the tube. I use both metric and imperial drill bit gauges to measure the tube and then use the drill bit that most closely matches the fit.

 

[Wrongway]

A nice tip that Walter, thank's. Just ordered a pair of gauges from eBay for under a fiver.

Walter I question your out of round statement this is immediately fixed since the tube dictates when you turn you are in parallel with the tube again surely. We all turn after glueing. I do like a good fit for strength.

Thank you, it's my fault for not being prepared and with such little shed time I was hoping my mistake would not be costly.

Many great answers and tips as usual.

Fathoming it out oneself is part of the fun and I do need to do more of that myself. I guess I'm of the google age. " don't think just ask" etc.

I think I shall invest in a range of drills and gauges then I will always have an option.

Cheers gentlemen.

If you get stuck give us a shout as I have a spare of both sizes needed but they are only standard twist drill bits. I bet we are at opposite ends of the County

 

[ni9eofse7en]

I agree with Walter, but Grumps mentioned chocolate and I forgot what the question was!

 

[EStreet]

Yes if your drill hole is over sized it can be out of round.

Yes turning *can* fix out of range but there are many cases where it will not clean it up by the time you cut it down to size.

Yes it is better to measure and go from there but this assumes you have a good selection of bits to pick from.

Not sure if Jim allows that kind of drill porn on here fella....
