MichaelG Thank you for your kind offer but as you see I did it in jpg as well and it looks fine -- took a bit longer than anticipated but thats life !!

Redsetter -- well yes it is but then there is the old adage "if a jobs worth doing its worth doing well" personally I just like things to be made to a good standard.

Hi Chris I have created an album on here with some photos and a drawing of my bed stop, the Super 11 bed is 95 deg ! I also have a pdf of the drawing but cannot get it to load !!!

You also need 2 off 8mm bolts, 2 x 8mm washers and 2 springs -- see the photo's,

springs are O/D 0.473"  ;   Wire 0.031"   ;   1.500" long

Chris, As Clive says Journeyman John has posted a good basic design however I have a factory stop on my Super 11 lathe and looking at your photos of the V10P bed it looks identical so I'll go and do a drawing of my stop but please PM me with your email -- never got to grips with posting drawings on here. My drawings are done long hand no CAD etc and the only way I can send them is scan to PDF etc and email them.

Incidentally the clamp bolts are the same as on the 1024 i.e. on the top -- much easier to use than when underneath.

Cheers John

Morning Dave, a steady hand a decent grinder with well dressed wheels and a good eye, I honestly don't use anything special just experience over many years, when I did my apprenticeship in the 60's we were expected to grind our own tools, there was of course a tool room for fancy stuff and milling cutters but no disposable tip tools and we all ground our own. Disposable tips started to appear in the mid 60's I think.

Hi Les, my tools are mainly made from the old UK tool makers blanks, Eclipse, Osbourne, Clarkson, Super Capital etc but I have also used some of the Chinese HSS sold by most of the usual ME suppliers on here and been pleasantly surprised with the performance of the tools. You can of course keep an eye on "the bay" for old school tool blanks but try to buy unground / unused ones.

As far as what you can machine, well most steels and any non ferrous material, some of the modern high alloy steels may well present a problem but in most model engineering you are unlikely to use them. I recently turned a replacement part that was a little over 2.5" made from EN24T using HSS tools, this is a fairly tough material but well within the capabilities of HSS. Indeed I rarely use carbide but it does have its uses and advantages.

Joe why not consider a bore gauge see this link, not too expensive and useful afterwards ,

**LINK**

Another alternative measure best you can with the tele gauge then make a multi stepped plug gauge in 0.002" steps, the steps don't need to be very long, then when you are confident of being very close to the size make or alter the gauge to longer steps and test again, last make/alter the gauge to the final size and test. About 2" of aluminium bar should suffice.

Hi as far as I am aware most are cabinet mounted and larger than a Myford but not much bigger footprint I think plus you will get more machine for your money ! They are however not to big in my opinion and make a great home machine. -- have one but industrial size.

John

Hello John welcome to the forum, not a bad idea to add your location to your profile -- town , county, or ???

As far as a lathe goes almost any screw cutting lathe will do both left and right handed threads as well as imperial and metric. You do however have limitations when cutting metric on an imperial machine and vice versa, either way you need a conversion gear in the gear train 127 or 63 being the norm.

You need to decide what size of machine you have room for and of course your budget, reading what you say I think a Boxford or similar would be a good choice and preferably with a "norton gearbox " for screw cutting if possible. Along with other machines I have a Myford S7 -- a brilliant machine but the only problem is the spindle bore size - rather small !

Cheers John

Yes Ian completely free hand no gizmos only a protractor or thread gauge etc to get the correct angles. I don’t worry too much about the angle being “dead on” to the main shank on say a screwing tool just close enough then set it spot on in the tool holder.

Thought i maybe should add the other photo's as well

Hi All there often seems to be discussions on grinding HSS tools so I added a small album to my photo's of a few selections of tools I have ground up over time and use regularly.

All are free hand ground on a normal bench grinder from standard HSS blanks, some have a tool ground on each end, some from round but most from square HSS.

Hope it interests some members and ig you want any more info please let me know

Hi Sean, I use Albee gas which is part of Air Liquide but ti probably depends on whether you have a depot near you, have a look at R-Tech welding as well. Just looked at Albee and there seems to be a couple of suppliers you may be able to use. Cheers John

Forgot to say I went for Albee because they do Oxy-Acetylene as well as inert gases.

Bought one some years ago -- absolutely rubbish so sent it back for a refund ! In fairness it could be improved if treated as a set of castings.

Johnboy25, Ebonite is used extensively in the gun trade for stock extensions, butt plates etc so they your local gun shop. If you don't have any luck PM me and I will try to help

John

Can't help John but this will bump you post up, may be worth adding an advert in "wanted" adverts

"So, the answer is a barrage where turbines power up while filling and also while emptying. All feasible and there are several suitable bays and areas for such enterprises. Wave power, this sufferes from sea/wave action and seems to also have died down now.

Clive"

There is a great danger of an environmental catastrophe with sea barrages, if they can be constructed so that the generating does not impede the flow in either direction then they would be fine. But if not the damage to bird life would be a disaster -- Morecambe bay has several times been suggested for this type of system but fortunately has been quashed ! There are some 40K waders who rely on the time between tides to feed, if this time was curtailed by storing the water then releasing it when WE need energy they would perish. It was said they would just move - really - where to ? there is no replacement for their food source. That's not to say we cannot use this type of system but it is essential that it does not impact on our companions on this planet, in this case the wading birds together with the migratory fish.

Kwil, I agree there are far too many of us and our species is expanding at an alarming rate, I too have said for a long time that Mother Nature will come along and sort us out !

Yes Michael a remarkable man and most people know nothing of him. Some years ago there was a drama on the TV showing his life and work. His clocks are in Greenwich and we’re almost “lost” but fortunately rescued for posterity.

Was the shed door open or closed ?

CJ, you want say whether you are moving just the machine or machine mounted on a cabinet ? I have moved mine several times plus assisted with others.

What I always do is use a steel plate cut to slide under the bed ways at the front with a hole to suit a bolt or lifting eye then if a lifting eye another plate on top of the bed ways so the eye passes through both and clamps them securely to the bed -- another way I/we have used a piece of 3 x 2 timber clamped on top of the bed long enough to make a lifting handle either side of the machine and 2 men can lift it easily. From what you say this would not work for you because of space restrictions.

Since you have the crane I would use the lifting eye method -- safe and easy, do of course balance the machine before lifting to full height.

Welcome David I'm sure you will enjoy this very active forum, do take care with making air rifle parts -- make sure none are to increase the power beyond the legal limit of 12ft/lbs of energy.

Cheers John
