Yes and the Super 7.

Thread: Tailstock WANTED
03/03/2019 14:08:44

Might be worth talking to the author of the page. You may find there's an Emco lathe (or Chinese clone) with a tailstock that fits.

Thread: Parting off - front or rear
03/03/2019 13:52:51

I'm a convert to a rear tool post for parting off. No dig ins at all since changing and I love the way the swarf drops clear. I use a tipped blade in a Dickson style inverted holder.

Thread: PCM Boring head.
02/03/2019 13:29:46

The boring head looks well made but I want to nominate that ground tool bit for the "Frankenstein Tooling" award.

Thread: Low rate automatic house plant watering system
02/03/2019 10:26:45

Car windscreen squirter motors supplied with water from a central water reservoir operated electrically either individually or in parallel or on timers.

Thread: Warco Rotary Table - What Grease?
01/03/2019 16:23:54

I stripped and cleaned a 6" rotary table a couple of years ago. Re-lubricated it with straight forward Castrol LM grease and it's been fine. It has been known for me to blend a drop or two of oil into grease to reduce the viscosity a little with no ill effects.

...... together with a sudden loss of grip at the rear end as the axles swing under the car pivoting at the UJ at the differential. There is no slow transition. It tends to go from grip to no grip very quickly.

Transverse leaf spring and a tendency for the rear wheels to tuck under. The system was tweaked to make it slightly better on later cars but still somewhat tail happy in the wet going around roundabouts. The rubber doughnut version used a lower wishbone rear rather than letting the axle shafts take the strain.

Thread: Jacobs arbor marking

I didn't seriously think you would. Mind you I have seen it. A friend of mine many years ago had a Myford ML2 with a 1MT tailstock and a 1/8" to 5/8" Jacob's chuck hanging off it.

Sometimes less is more.

27/02/2019 19:00:27

A 1/2" chuck on a 1MT arbor? That's bold. I hope the tailstock barrel is near perfect.

Thread: Plastic Balls in Bearings?

Rose joints are great for racing but they tend to wear quickly. All the exotic kit cars like GT40 replicas use them but they wear badly and make the car a bit of a bone shaker on the road. Actually the Triumph front wishbone suspension units were very highly thought of. Lotus used them on their early Elans. The secret is to keep the threads on the bottom of the trunnion well lubricated. Better not to talk bout the rear end unless you have the rubber doughnut rear suspension.

+1 for the slot drill. Use high revs too to keep the tooth load light.

Thread: Jacobs arbor marking
27/02/2019 14:07:27

Let's put it this way. I paid 3 times what you charge for the same arbor so if it came from the same production line, I might feel some frustration.

27/02/2019 13:39:59

One would hope that the owner of a brand name associated with quality would ensure that only goods worthy of that quality were being sold under that brand name, otherwise it would be a waste of purchasing the brand name in the first place if its reputation took a nose dive and made it worthless.

27/02/2019 12:10:59

Yes, thanks Ketan. Good to know my Spidey sense hasn't deserted me although a little frustrating to know I could've sourced, in this case, the identical product elsewhere for half the price.

27/02/2019 00:28:52

Interesting. Thanks for researching it. The arbor runs true. Difficult to quantify its qualities any more than that without using it for a while. The upshot is, it's already fitted and being pressed into service.

26/02/2019 22:33:11

This whole subject comes back to trust in a brand. One pays the extra specifically to avoid any uncertainties.

Thread: Plastic Balls in Bearings?
26/02/2019 20:06:29

Back in my car restoration days, I used to specialise in Triumph sports cars and the lower front bronze trunnions of the Herald/Vitesse/Spitfire/GT6 cars, that carried all the weight of the front of the car, had simple plastic bushes shaped like top hats about 11/16" OD and 9/16" I.D. with a steel sleeve inside that. Yes, they wore eventually but they were easy to fix and obviously deemed up to the job.

Presumably because of the corrosion steel bearings would suffer in close contact with sea water. Plastic bearings are more than capable in non dimension critical situations.

Edit: ... so we must assume that the seller is using an old stock-image.

Call me old fashioned but I like to get what I see otherwise I wouldn't necessarily choose that particular item. It's arguably false advertising.
