Thread: Myford Super 7 lathe upgrade to 3 phase
13/05/2021 16:31:39

My only comment apart from saying you dealt with a good (and helpful) supplier is that the bench does not appear to be stiff enough to enable a enduring levelling setup for the lathe bed to hold its settings. Perhaps I should await your experiences as regards precision of turning ie lack of taper.

Well done otherwise.

Thread: using CNC mill to cut vinyl letters and numbers

My local garden centre used a specialist in house vinyl cutter for all of its instore advertising. Perhaps you could save yourself some effort if you can find someone like that to do it for beer money.

There is one washing up liquid that claims to be kind to your hands, anything but!! Leavs mine feeling raw so not in my house.

Thread: Myford Super 7 apron seized??

Yes of course the proper name is "thrust washer" and they are just plain "thick" washers that take up the gap between the gear and the circlip, for instance.

You say they apply "end load" onto the bevel gears, they should merely position the gears so that they can turn freely when assembled correctly, any axial load on them comes from the bevel gears trying to move apart. They should be bronze, not shown as available spares, neither are the circlips, but they will be standard sizes of course, perhaps Myford could identify them for you if asked.

Manual is S723W, (actually there is an error on the Myford site, there are two manuals with and without power cross feed. S723W and S723R, Myford manage to miss number the first as S273W !!). Highes LA number is LA61.

Lastly, you public profile does not show a location, a general area would be helpful as one of us may be nearby.smiley

Martin, OP did say he took everything apart and cleaned it, so it may have been disturbed.

The leadscrew nuts are eccentrically mounted so the Eccentric Sleeve LA57 must also be set up to ensure the correct location.

When I stripped my own apron many moons ago I did not have this problem upon reassembly.

The so called thrust washers (parts LA50 and LA 28) are there as spacers and should not apply end thrust to the bevels.

When the cross slide is off the carriage, or if you withdraw the cross slide leadscrew, can you drive the bevels (plunger engaged) by means of the main leadscrew?

they replaced comfortable trains on both the east coast & the GWR with what have been reckoned to be the most uncomfortable long distance trains ever built - specified it seems by the 'experts' in DfT (their last 'masterpiece' was the Thameslink trains) - maybe once the Gov has recovered from Covid they might get around to publishing the long awaited Williams report and appoint the arms-length guiding mind that is so required to recover from the failed franchise model and the utter stupidity of the 'do not use public transport' messages - which will probably kill more people from air pollution than use of trains would have from covid.

Since when has a Government Department designed trains? As for the comment on air pollution versus Covid, stick to facts.

Thread: What odd grease?

Could Kwil clarify if the number 2 Castrol is suitable, as I'd planned on the replacing the grease on my boxford vm30 gearbox in the near future, I found this that gives the impression the double zero grade is the semi fluid?

 

 

The double zero is one grade thinner than zero. The number 2 Castrol is one grade thigher than number 1 etc.

The numbers are from the NLGI Consistency number

 

I meant is the number 2 semi liquid, it says 'general purpose bearing grease' in the information I found, which makes me think not, or is number 2 semi fluid, and the double zero near oil consistency?

Pete Per Boxfords' original maintenance instructions which I have:-

Gear Box - Is lubricated with B.P Energrease F600_EP at works and sealed, it should not require further lubrication.

Main Spindle Bearings -Are filled with SHELL Alvania RA at works and should not require attention.

When I wanted to overhaul my VM30, a contact at Castrol told me the Castrol Spherol  EPL2 was the correct grease. It is a dark grey/black material and pours, definately semi liquid.

Semi Fluid EP Greases are semi fluid, extreme pressure, lithium thickened greases developed for lubrication via automatic lubrication systems and applications such as gearboxes where a grease is preferred because of leakage problems with conventional gear oils.

Does this answer the question?

Description:
Castrol Spheerol EPL 2 Lithium Grease NLGI2

A multi-purpose semi-fluid Lithium, EP grease suitable for use in Centralised Lubrication systems and enclosed gearboxes.

Castrol Spheerol™ EPL is a range of greases which comprises lithium based products, containing highly refined mineral oils, fortified with extreme pressure (EP) additives as well as corrosion and oxidation inhibitors.These greases have been formulated with additives that provide good film strength under medium to high loads.

The Spheerol EPL range comprises general purpose greases designed for plant wide lubrication. These greases provide good protection against rust and corrosion as well as resistance to water wash-out; which makes them particularly suitable for equipment where moist or wet conditions are common.

Thread: Faster Screw-Cutting
24/04/2021 15:47:55

I have a Meek designed dog clutch fitted to my S7, I also use a GHT designed Retracting top slide.

To lower the impact on the dog clutch pin I also momentarily use the drive clutch whilst the leadscrew goes into reverse.

Screw cut at around 200-400 rpm according to the material being cut. Fast enough for me. Very rarely use a die.

You only need 4 sizes of collet

6mm 10mm 12mm 16mm

I have those. I tried a 1/2" shank cutter in the 12mm one and it was a little tight. The collet did not seem much use afterwards so it might be an expensive way to work. Similarly, the 16mm one was a bit loose and it was difficult to remove the mill after welding it into place.

These sizes refer to Metric sized cutters, if you want to use Imperial sized cutters (as you say you have a1/2" = 12.7mm and so forced in an oversize shaft), you will need the appropriate sizes.

If you have ever tried to lift a Bridgeport 48" table you might decide that a mere vice at one end would not be that significantwink
