Thread: Boring for a Beginner
26/03/2010 16:49:22
I do not use a setting guage, [I do not possess one even]. I always take a cut across the end of a bar when tool setting a QC holder. Look at the quality of the cut surface once all is running true, that and the "chip" quality will tell you whether or not the tool  height is correct.

Try setting the tool height better when turning externally.

Wormwheels are indeed a special form, they do wrap around the helical leadscrew, around 25% being the norm. This will also enable them to span the slot in the leadscrew used to drive carriage gearing. Wormwheels have to be hobbed with a cutter designed to match the leadscrew, both the hob and wormwheel blank have to rotated at the correct speed to achive the best result. Some slash cut the blank to try to achiev the drive but a sutable geartrain is the best way. Look at Ivan Law's Book Bears and Gear Cutting (Workshop Series 17) if you want to pursue this.

The advantage also of decent coated branded tips is that you can also use them dry, without coolant. Just try to keep to the correct grade for the material being cut.

Thread: Tony Jefree`s CNC conversion of the Myford ML7 Lathe (MEW May 2008)
20/03/2010 16:23:56
I kept the original Myford leadscrews on my non CNC S7s but fitted needle thrust races in a modified Myford bracket. [shorter bearing length and with a shortened adjusting "ring" to set end load]

"Paulthecad" has a good ab initio intro course to 2D CAD.
 
The MEW series on 3D was excessively long for many people I am sure, it is fine to set the scene but it just went on and on and on............, far beyond what an average user or potential user would need to start with.
Thread: Riveting
19/03/2010 15:08:04
I have found that it is essential to close the plates together with a tubular tool, then lightly hammer the rivet end to fill the holes, this barrels the rivet stem, then use the closing snap. It also helps if the cut end is flat [sheared or filed] as this helps to keep the closing force square to the stem.
Thread: Lament for a lost grease.

Do you really mean Castrol LM, a light buttery coloured grease you used for nearly everything?  A general purpose Lithium based grease? Still can get it.

Thread: Line Borer
18/03/2010 11:50:59
As I recall, production tolerances on old car main bearing were quite tight, with cylinder bores measured to 4 decimal places and using matched pistons. That said, you could consider a mandrel supported in two ball bearings, the outer of which fits the bearing housing or is mounted so to fit and then using a cutter mounted through the mandrel to cut the other renewed bearing shell, assuming it is a white metalled one and you  have a 3 bearing crankshaft. It would be quite slow because you would have to take the final cut at the same settings on all bearings, unless your crankshaft is unequal anyway.  An idea for discussion perhaps?

Reminds me of a youth, [not me I hasten to say],  who, standing by a machine planer (wood), which was making its usual high pitched rotational noise, passed his flattened hand across the blade area, saying "is it working??" Tables were set flat and the guard was in place fortunately. You never can tell, intelligence does not enter into it.
18/03/2010 09:04:59
Rather than being specific about which connector to use, etc. the ones used could be stated as being an example (hopefully of being good practice), HOWEVER an overiding statement such as " Electricity can kill, if you do not fully understand what you are doing, consult somebody for advice who does understand, "
Thread: CE mark for boilers
15/03/2010 12:17:26
You do not have a problem. As it was made before the CE mark came into play it is not required to be marked. Marking is not retrospective. Just have it hydraulically tested, then steam tested by your local club inspector as normal when you want to put it to use.
Thread: Boiler life
14/03/2010 20:44:12
I recently saw a club loco boiler which had been in use for 30 years. Not a pretty sight however, but it had been working and was due for replacement. It all depends on the standard of silver soldering, good staying and workmanship, adequate copper thickness with sufficient fillets etc to withstand the attacks by combustion products.
Thread: Very basic milling questions
14/03/2010 08:36:15
There are charts which enable you to "look up" material, diameter of material or cutter and hence derive rotation speed and feed rate.  You can choose max metal removal, industrial style, or max tool life with a slower removal rate, or somewhere in between.
Thread: myford boxford or colchester
14/03/2010 08:31:59
It is horses for courses. I have several Myfords, started with a ML7 "new" one in 1954. I have a PCS Super 7 with gearbox and imperial/metric  dual banjos. I also have a Harrison M300 the latter being because I needed a large through bore, even at 1" I could not go the the larger Myford. Having said all that, there is nothing wrong with a Myford, you can work them very hard with the correct tooling AND you have excellent factory support here in the UK.
 
Sorry fatbazz but you must live in a micro-house, headstock ball bearings for the Super 7 are not expensive and considering you get a "good as new" bed + carriage for your regrind from Myford, it must be worth every penny.

Thread: Thread up to a shoulder.
12/03/2010 10:37:08
Since the thread strength is determined by the minor diameter, the undercut, if taken to that minimum, should not affect the strength. By all means round the undercut if you must, but the strength will not be significantly improved in tensile load.
Thread: Screws, how far from the edge?
12/03/2010 10:31:21
With this size of toolpost and 8mm tooling,  M5 is more than sufficient. Keep the screws centred on the tools.
