Machining out wrecked bearings - Hard turning.

"Can you fit new bearings in these rollers? You'll need to take the remains of the old ones out first."
"I don't know how we can do that. Looks a bit tricky..."
"Can't you just put them in a lathe & turn them out?"
"But they're ball races - really hard!"
"Oh!...See what you can do?"
"Well, O.K..."
Lathe used is a Colchester Triumph 2000 with a Burnerd Multisize collet chuck. "Standard" CCMT Tungsten Carbide inserts used in the boring bar.

This Ducati cylinder head needed re-machining on the recessed face that sits on the cylinder barrel, as a previous repair had left a slight dip in this surface. Although this could be done with a milling machine, it seemed that turning on a lathe would be a better option. In either case, holding the cylinder head on the machine would not be straightforward & I needed to make a fixture plate to ...

Needed to build up the remains of the centre stand lugs & then grind & file them flat & level so that there was somewhere to weld on some new plates with holes pre-drilled for the centre stand pivot screws. Then those plates could be cut, ground & filed to shape...

This Triumph Tiger cub frame had not only had the centre stand iremoved (which was possibly a common thing to do if the bike was going to be used for trials or trail riding) but had also had the pivot lugs on the frame cut off, and in a pretty crude fashion to boot! The repair needed a fair bit of welding plus cutting, milling, turning, drilling, grinding & filing!

Part 2 of making a replacement boss for a digger/excavator, using annular cutters (or core drills), an internal parting off tool in a shop made boring bar, & some standard boring operations. The smaller core drill (43mm dia. x 53mm max. depth of cut) is an HSS cutter with 11 teeth & made by BDS. The larger core drill (65mm dia. x 30mm max depth of cut) is Tungsten Carbide tipped with 9 teeth & ...

I needed to make an 80mm diameter hole in a 4 3/4" diameter piece of mild steel which was going to be replacing a worn out pivot boss in an excavator. The largest twist drill I have is only 1 inch dia. & using that would have left a lot of metal to be removed by boring so I thought a better option would be to use some core drills/annular cutters to make a much larger hole before needing to use ...

I'd made the tools used in this video several years ago to make some Aluminium intake tubes for a Ford Cosworth. Simple taper turned Steel pieces - the internal taper to shrink the end of a 2 1/2" diameter tube & the external one to expand a 2" diameter tube. I only needed to close down some 2 1/2" tubes for the job shown here but thought I might as well show both tools being used.

A few things to take from this video. First, tack EVERYTHING in place before doing any "proper" welds. On this piece I should have tacked the centre tube & all the ribs in position. Second, trying to run a fused weld between 2 pieces of 5mm thick mild steel will have hardly any penetration... Third, MIG welding mild steel is much quicker & puts less heat into the job than TIG. Fourth, don't ove...

Sometimes basically simple jobs are not as straightforward as you'd hope! Getting parts held in the right place can be fiddly & the actual machining doesn't always go smoothly. Chatter, caused by vibration in the tool and/or the work can be a major bugbear... Lathe used here is our Colchester Triumph 2000 with the work held in a 12" 4-jaw chuck. Turning tools used on the Cast Iron drum were a 1...

We do get some odd things brought in to be fixed/repaired. I've worked on parts for ice cream making machines before - Rossi's up the road from us had some pretty old equipment & I think the part in this video was brought in by their successors. So another old part, probably long out of production - maybe not, maybe just hard to get hold of - likely made in Italy originally. How on earth it got...

Center Line Wheels - Shiny!

Просмотров 1547 месяцев назад

These classic Center Line wheels were brought in to us to be polished & I thought it was interesting to look at how they were made. Rather different from modern alloy wheels. Center Line are still in business but their wheels are not made in quite the same way now. Still not cast, but 2 pieces riveted together rather than 3.

Part 2 of drilling out broken bolts in an exhaust manifold. More of the problems that can occur with these jobs. Ended up putting Helicoils in 2 of the holes & with hindsight, it would have been quicker to have drilled out & Helicoiled all 4 holes rather than trying to preserve the original threads...

It's always a bit of a challenge to remove broken screws/studs/bolts And when they are properly rusted in you know they will have to be drilled out. Often not straightforward & on this job it would have been quicker if I'd gone straight to drilling the bolts out completely & tapped the holes to take Helicoils... Job done on our old Beaver VPRP turret mill.

Someone wanted us to drill out & thread the bore of a motorcycle alternator rotor, & then broach a "keyway" slot in it. They supplied the broach but didn't realise that a guide bush was needed... Machinery used in this video - Steinel SH4 horizontal milling machine, Marlco arbor press.

A broken bolt to remove & a broken casting to weld up. Getting the remains of the bolt out was pretty routine. Made easier by being a through hole so it could be drilled from the reverse side. Hoped that the drill might bite in, grip the bolt & screw it out the front side & that's exactly what happened. The broken part of the Aluminium casting needed to be AC TIG welded.
