Re: Woodworking with the mini-lathe
Vikki, congrats - I didn't say anything earlier, but i thought to
myself that with those tools it would be a miracle if you can do anything. Just wait till you get your hands on a true HSS gouge. Barry--- In 7x12minilathe@..., "wrlabs" <wrlabs@...> wrote: . html

I reckon you could easily fabricate a bigger mounting block for the rodI think you could use the existing guard if you were to build a riser block to raise it by about 3/4". Shouldn't be to terribly difficult to fix, but it really should have been done by SIEG, not by the end user. |

Re: mini laths (and OH&S)
Hi Ian,
I don't want to knock your training and comments, but I suspect you've been out of the industry and legislative requirements for a while. Over the last decade or two there's been a bureaucrat takeover of industrial safety. I'm sure the drive comes from insurers covering compensation liability. That in itself is not a bad thing. They measure risk by payouts. However, they value a life at $X - an obvious underestimate for the individual. They value an injury at the payout including ongoing aids, etc. Most significantly, they don't measure the relative costs of implimenting various alternate risk management measures, only the savings on payouts. That cannot achieve a fully balanced outcome. Yet the legislators are on side and that's resulted in enforcement of a bureaucratic top-down safety system which often over-rides safety practices developed over the recent two centuries of industrialisation. They'd claim consultation. However, the safety legislation enforces a structure aimed at unskilled workers. Not surprising. The structure was devised by unskilled administrators forming committees advising bureaucrats. Maybe I'd best get off my hobby horse at this point and quote you the legislated hierarchy of controls as used in Australia (and elsewhere). From www.nohsc.gov.au/OHSInformation/Databases/OHSSolutions/hierarchy.htm <; .htm> : The Hierarchy of Controls = preferred order of control measures for OHS risks. 1. Elimination - controlling the hazard at source. 2. Substitution - eg. replacing one substance or activity with a less hazardous one. 3. Engineering - eg. installing guards on machinery 4. Administration - policies and procedures for safe work practices 5. Personal Protective Equipment - eg respirators, ear plugs. Training is seen as a means to help this all work. However, it is not a substitute for using the above list. That means an employer who teaches his employees about the hazards of the lathe chuck but fails to impliment the highest feasible solution in the list is subject to The Big Stick. Hence the chuck guard implimenting the Engineering Solution. Other international jurisdictions will differ in detail but it's pretty much a global movement. I have no problem with you training youngsters in the older safety practices. I do so myself. I also know they are going to live and work in a world governed by the above approach. When they jab themselves in the stomach because they stood in line with the unprotected tang of a file nobody will question their contribution. Only whether the employer identified the hazard and applied the above process to manage the risk. So that's the long story behind the chuck guard. And why I dare not remove it in my workplace. And why hobbiests and anyone else not beholden to worker's compensation insurance companies are free to remove it. But I still say SIEG STUFFED UP by putting a 6" chuck guard on a 7" lathe. In fact, by creating a strong inducement to its removal, Sieg or their distributors may yet be found liable for "foreseeable consequences".

Re: Slitting Saw Recommendations
--- Hi Rance/Vikki,
For the occaisional times I need a slitting saw, I bought a few from Grizzly a couple of years ago 2.5" dia. w/ a 7/8" hole, in different thickness', and the "fits all" arbor. I found that the saws don't run true with that arbor, although with care, they work. I also bought some smaller dia. (I think they're 1.75" dia) with a 1/2" hole, at a flea market, for literaly pennies. The 1-1/4" dia. of the arbor leaves very little blade showing on the smaller ones. I made a 7/8" arbor from alum. round stock, and a 1/2" arbor from 3/4" round steel rod. They work much better,the saws run true, and are easier to use. And easy to make. The 3/4" rod arbor for the smaller saws leaves more cutting room. The diameter and thickness of the saws depend on your needs. So far these few sizes have worked for me. If blanks are available, making your own is even easier. Frank In 7x12minilathe@..., "wrlabs" <wrlabs@...> wrote: to my generalaccessory order but there are soooo many to choose from.

Vikki,
that slitting saw arbor's 1/2" shank might be a problem ;-(. I don't have a taig lathe but that thing sure would be a problem with my mill which I believe uses the same spindle. A blank taig arbor is cheap, turn a step to match your saws ID. 5 minutes and the shipping is more than a single blank.

Slitting Saw Recommendations
It Seems that a Slitting Saw & arbor would be prudent additions to my
accessory order but there are soooo many to choose from. For general work (not slotting), what size would prob. be best (most common, most economical)? What arbor size is the most common? I expect I'll be doing mostly alum. but might need it for steel too. Seems that an arbor might be a good first project. Thanks. Rance |
Re: HF 8x12 - Tool Bit Size
Ed,
Thanks. That's exactly what I needed to know. I don't plan on buying the commercial QCTP, I plan on making my own. Prob. build it for the 3/8" tools. I do like the idea of using the 4-way that comes with the lathe. For now I may buy a few 1/2 AND 3/8.

Re: mini laths
G'day Mike et al.
CHUCK GUARD. You have to seriously wonder at the value of the chuck guard. Somewhere in OH&S regs they say all rotsting pats must be guarded. On automatic machines its presence is justified but on manual machines it adds little to safety and may in itself create a hazard. It obscures you vision when sighting how close the tool is to the chuck and puts you at risk of crashing the tool into the chuck. My lathe has a guard, thankfully without a kill switch so it is always up; I only put it down if coolant is being flung about by the chuck. I have seen others in this group advocate leaving the change gear cover off. I do not endorse this because it would be easy to let your fingers stray towards the gears when using the lathe. The chuck guard is another matter. Let's do a JSA (Job Safety Analysis) First danger: leaving the key in chuck; this should be overcome by developing good habits; also starting slowly means the key drops out rather than is flung out (this is inherent with the speed control needing to be reset. Second danger: clothing being caught in the chuck dragging in the operator; overcome by wearing correct clothing, short sleeves, no ties ec. Third danger: ring finger getting caught, ripping off portion of finger; overcome by taking rings off. Forth danger: Swarf etc flung from chuck into eyes (it does happen); overcome by wearing safety glasses. The list goes on but each risk can be controlled by correct practices. IMHO, take off the chuck guard and bridge out the limit switch. As a professional I am safety focused, here is a very recent example. I had a family from our church over for a meal. The son is doing metal work at school and together we turned up a quicky widget on the lathe. The corners need rounding so I showed him how the file must be used left handed and stressed that your arms must not cross over the chuck and the file should be on a line passing outside the body. Next day he went to school and was using a lathe with a file. He apparently followed my instructions much to the surprise of his teacher who asked how he learned the correct way. Response, "The pastor of our church showed me!" My point. We must learn SAFE PRACTICES along with the skills we master and, using groups like this, we must pass them on. the chuck guard does little to enhance safe practice, it is appropriately named, chuck it away! One good turn deserves another. Regards, Ian --- In 7x12minilathe@..., "Mike Payson" <mike@...> wrote: I'm not sure if it's standard to all of the 7x's now, but the HF adds a chuck saftey shield that is only 3" from the center of the chuck,so without removing it, somehow moving your work 3" or so from thespindle, the largest work you can possibly turn is 6". |

wrote: in a way it would fit safely on the remaining piece? That would let youkeep that 'safety feature' of the machine during normal work, to have it quickly Hi Marcello, I reckon you could easily fabricate a bigger mounting block for the rod and microswitch to place the rod further out. Say 3 1/2" from spindle centre. The problem is the clear plastic guard itself. Perhaps you could heat form some clear polycarbonate over some large pipe or turn up a 7" wooden former (with the guard removed). The original is semi-enclosed on the h/s end with a partial reinforcing web. That's easy for an injection molding machine but less than easy to fabricate. I guess transparency of the end isn't so important so you could improvise with sheet aluminium. Here in Oz we have some 3 litre soft drink cans about the right size to do the whole thing in tinplate. At the end of the day it's gonna look real ugly no matter how you go. You'd have to be really committed to keeping a chuck guard to go for it. Yet it would have been so easy for Sieg to mold one the right size. Perhaps if we all pester their tech support they'll put out a 7" accessory guard. And if we all returned our machines to suppliers for refunds (not 7" as advertised) they'll fit them for free! Dream on... John |
Re: mini laths
MZT.Groups
On the HF, the lathe guard mount itself is 3" from the chuck center.Thank You, Mike, now I've got a clearer picture of the machine. That would mean you cannot simply unscrew the guard because the rod would stay in place. Would it be possible to cut off part of the rod and modify the guard in a way it would fit safely on the remaining piece? That would let you keep that 'safety feature' of the machine during normal work, to have it quickly removed only when it prevents you from doing the job. Marcello |
