Self Lubricating Bearing Bushing sleeve

[transatlantic]

Anyone know where I can find the bushings he is using in this video?

I want something that will work with common dowel sizes, so figured I'd go with 8mm inner and a length of around 20mm.

I have spent quite a while scouring ebay and the like but have only come up with these which are a little short. I guess I could stack them, but would like a single piece if possible

They look like what I would term brass bushes. Not sure brass would last long in that application though.

 

[transatlantic]

I found something similar under 'M8 Steel Spacer'. But they're crazy expensive .... around £4 each

If you look closely when he gets them out of the tray you can see the description on the label says 58076 Bronze Sleeve Bearings

How about these?

Have you tried brass tube listings, just cut to whatever length you need? At-mo metals are one of the sellers I've used in the past.

 

[Johnboy]

I would use drill bushes for that application. They are hardened and meant for use in drilling jigs. Just google drill bushes. Www.boneham.co.uk is one source.

After a 2nd look at the linked video, I'm not sure that they're tubes (or plain bearings) at all.

They remind me of the "stand offs" that used to be used in the old days of single layer PCBs mounted into instrument cabinets, etc, and maybe are even still used for prototyping work, I'm not sure.

But I agree that brass is unlikely to last all that long in the application shown, especially since I have the feeling (just a feeling mind) that the edges of the flutes on a spur bit are a bit sharper than generally found on normal "jobbers" twist drills.

Why not buy just a length of Mild Steel tube and cut the guides off to the length required for the jig (hack saw, then de-burr) ?

Here anyway such tube (and rod, plain and threaded) is usually available in our local DIY Emporia, and although ridiculously expensive in relation to "real" prices, you won't need much for that job.

Mr Terroo is on it - as soon as I saw the video I noticed they were Oilite.

 

[Johnboy]

Oilite bushes indeed, not good for this application though. They will wear out very quickly. As I said, drill bushes are designed for this.

[iNewbie]

I know they're better, but he asked what they were,

 

[transatlantic]

Thanks for the links guys. Drill bushes were what I looked into first, but a little too expensive as I wanted 5 of them, which comes to £40!

Steel tube would be nice, assuming I can find one with an 8mm innner diameter

I think I'll probably go with these http://simplybearings.co.uk/shop/p12029 ... _info.html

 

[SteveF]

It would require a little bit of planning but what about skateboard bearings?
should be pretty hard and can be had with 8mm ID

or these that are only 12mm OD

Agreed that hardened steel tubing/drill guides/bushes would be best for this, but as said above, maybe quite expensive & perhaps not so easy to find. But unless you'll be using that jig a helluva lot, IMO ordinary MS tube will be fine.

Re your QUOTE: Steel tube would be nice, assuming I can find one with an 8mm innner diameter UNQUOTE:

Are you quite sure you can't pick some up locally?? I find it difficult to believe it would be so hard to find in Suffolk, but if you really can't find any (AFTER looking around!), drop me a PM with your address and the total length you need and I'll send you a length (if I haven't any in stock I'm quite sure I can pick some up locally with no bother at all).

Another thought (must be quick, I've nipped onto the PC while the guests watch some TV carp) - can you get those long (about 3 times normal length/depth) steel nuts easily? If so carefully drilling those out truly vertically (pillar drill) should work OK too.

I haven't had a look anywhere local, just a quick search on the bit metal stores and couldn't see anything with an 8mm inside diameter. The closest was 9mm (10mm dia x 1mm) or 8.5mm (10mm dia x 1.5mm). I'll see if I have anywhere local that I could pop down too. That way I can take an 8mm drill bit and see how close it actually is.

 

[memzey]

Could be wrong here but won't your 10mm OD by 1mm metal thickness have an 8mm ID?

 

[AES]

Sounds to me like memzey's quite right. If the OD of the tube is 10mm and the wall thickness is 1 mm, then the size of the hole (the "bore", or the "ID") must be 8mm.

My offer still stands, but I'm away on hols from 28 Dec until 8 Jan.

But a PM to me after 8th will produce what you want. The only cost to you will be the postage.

I feel like quite the idiot right now ....

Thanks AES, will keep that offer in mind, but hopefully I'm sorted now
