Stuff you have made today

Nice stuff, but, err, the duck?

haha, somebody gave it to the mrs. It's head has fallen off multiple times but not allowed in the bin, always has to be fixed

They look really substantial and better than any I have seen for that application

I'd have used a pair of these French stainless devices Mailllon Rapide Long Opening | GO Outdoors

 

[DAPPH]

Nope and I tried everything. Whats worse is I cant under stand it after 2 evenings scratching my head.

Unless someone has ideas Im going to hide it far corner of the shed and do something else. This 32mm shaft er32 was a great time saver but I have the spindle mount or mt3 I can use instead.

Not sure if this helps or is applicable .. Kram

Perhaps sharp edges on the collet act as scrapers inside the collet nut .......so push the alignment out a tiny bit .....


Her's my experience about such a thing .
My 3 yr old Chinese collet set up is a bit different as it's on a morse taper , but one thing I've found is on the 8mm collet the dead square sharp edges on the slots cut in the collet body often cause the collet nut to stick , grip because of the scraper effect on the inner faces of the collet nut for six or so threads. . It took a while to see the polished surfaces developing ( it took almost 60 plus thin copper pipes 24 mm long , held and precisely & re-shaped to 6 mm internal dia ) where it was catching .

I've only needed to use the 8mm collet in the set but suspect that filing the edges of the other seven collets will need doing to stop the scraping effect inside the collet holding nut.

It was cured by using a triangular warding file , I carefully took off all the outer sharp edges on the slots . Now everything is almost finger tight till it needs a nip of half a turn of the C spanner , everything runs true & as sweet as a nut .

That's very insightful. You could use one of those dense scotchbrite type de-burring wheels to take off the sharp edges on all of them quite quickly.

it’s interesting you say that some of my Cutwel collets are mega sharp

This was yesterday rather than today. Some Yamaha pipes. Don’t do these much anymore.

Any more pictures Brad?

I really need a new high quality earth clamp. My Lincoln 200A one has burnt the braid out, the brass pads are in good Nick but I’m getting arcing. @Jim Davey do you sell any heavy duty spring clamps suitable for 200A?

actually I should probably tag @andymdavey82 too

I keep looking at the tweco ones but ESAB products have gone to crap

Popped into the workshop on the way home this evening to pic up some lenses for the Crystal and decided to make a small body ER40 cuck for the lathe from some 60mm OD EN8.
Video of the lathe doing its thing with a couple of pictures near the end of the video and testing runout with a 10mm drill in the collet.

I know I've said it before, so at the risk of being boring I'll reiterate - I love watching your machines [all of then] at work!

If you look up Gibson exhausts/Allspeed on Facebook there’s tonnes. I only weld up the specials and stainless ones now. They’ve took it back in house for most stuff.

 

[Kram]

Good idea but none of my collets have sharp edges other than the swarf they came with in the slots that is cleaned out.
The ER32's were more used back when I was cutting with veg oil and some had a layer of hardened goo, but a soak in diesel got it all off clean. Most look like they were deburred with a hammer. Not pretty, particually the ER32's but they were all accurate once. I checked my MT3 chuck and that is just as far out! Its one I have not recut, still has chinese ground finish.
Need to put my spindle mount er32 in and check that, and a size Ive never used, 17mm.

Very tempted by the er40 sets, but I started looking up er50. In theory that can go upto 42mm, not that anywhere sells them.. but 2mm range so fewer needed.

had an allspeed on my AR50

Good evening @Hood. No ballast, had a visit from the owner yesterday, a progress inspection and he informed me that it will hold 12 bodies and some beer, expected weight is then about 4.5t. It will have a 30hp single engine and does about 6 - 8 kts.

Is that going to be a sort of pontoon pic-nic catamaran boat?

Yes, is the short answer. Was also informed yesterday that they have 4 of this stile of vessel and 22 'tinnies' in their fleet . That is a lot of boats to get damaged by the 'customers'

I’ve ended up with another shrinker stretcher body so I started on a new treadle stand for it this afternoon.

One more thought .
Have you tried to do a run out test of the head stock shaft & collet nut body when the lathe is running fairly slow say 50 RPM , by using a roller bearing on a bar and slowly advance it to the diameter ...use a stick to brake the bearing a bit to see if it judders once the bearing gets driven .
Thinking behind that ..... you might not discover any movement if you're turning it by hand .

Ahh, fallover feet....

I spent a couple of hours making a somewhat pointless breather gadget for the fuel tank on my ‘steam punk’ hot rod, not sure if it achieves anything more than a simple plastic drain hose would, but I fancied a play with sand filling small bore tube to coil/bend it without it collapsing.

I’ve ordered a tiny little filter to go on the open end, which will probably dissolve in the ethanol fumes...

I don’t have a really good option on a 250 amp earth clamp. I find them all to be a bit cheesy these days. However, this “300 amp” works very well as a 200 amp clamp.

We are selling them for about £6.00 + VAT.

Best regards

Jim

Your web site seems to be having problems, unless it's me. But I don't think that it is. If you click on the "Shop" tab you get a very basic unformatted page and links don't appear to be working.

I have found that happens quite often but thought it was me!
