Re: Mini-Lathe Fuse

Re: Things to Make
G'day Paul.
Things to make? I notice you include "wireless" in your handle. What push me over the edge to get a lathe was visiting a guy who makes reproduction antique radios. He had been turning knobs on his drill press and was complaining about the price of terminals he had purchased! I thought what an opportunity to make these up. I was into "radio/electronics" myself until I got sick of not seeing where the smoke was coming from. I still haven't made any terminals but I have made attachments for the lathe, bushes for my grandson's trike and 1 & 3/4 steamengines. I have rekindled old skills and am meeting new collegues through this and kindered groups. I keep talking about joining a local society of Model Engineers but I spend so much time in the workshop that I haven't time As Bill says, "a lathe is just a tool". I get a little frustrated by those who seem to spend so much effort working it up to get to a state of perceived perfection (the zero backlash fraternity) which in many cases would outstrip their machining skills. More inaccuracies creep into a project through the setting out than from the machine. Mind you any thing you do improves your skill level. If you can't find a need for a lathe, DON'T BUY ONE, give the money to a charity that could give some poor seamstress in a 3rd world country a ssewing machine or a pedal rickshaw to a breadwinner in India. Have fun, but make a difference. One good turn deserves another. Regards Ian --- In 7x12minilathe@..., "Bill Johnston" <johnston@...> wrote: How's that?

Re: Mini-Lathe Fuse
Rare is in the eye (or country) of the beholder :-)
The fuse is type M205 or alternatively GMA -- metric fuses, if you can believe that. You can find them easily with Google but may get hit with a minimum order size. In the US the 3AG type fuse is more common so you could change the holder to accept these. Some lathes use 3.15A fuses but most now use 5A. Check the fuse you removed, it should have the rating on it. John --- In 7x12minilathe@..., "Pete Lilja" <plilja@...> wrote: 7 x 14 and popped a fuse.

that non machining and non techno people would also enjoy looking at. It could even be viewed as an heirloom. I don't know if any plans exist for machining one, but Shopsmith has plans for a wood set. Of course, it's much easier to do the more free form work in wood, but given enough time, I think some very nice pieces could be made out of a couple of nice looking polished metals like perhaps aluminum and brass (or maybe bronze). Here is the Shopsmith page with the plan offer. Click on the places in the "index" box to see some simple drawings of the pieces. Of course, if you have CNC you have some advantages. I notice this place that talks about such a project out of different transparent color plastic... Here is a concept with fairly simple designs¡ Better yet, someone could design their own that lend themselves to mostly conventional machining activities, but perhaps still look interesting if the design is clever enough. A friend of mine who taught high school industrial arts had a nifty aluminum lighthouse project the class members would make. It had a base and a tapered body and some sort of interesting treatment at the top (maybe a little castle-like). The project involved scoring and serrating the body in a fashion so it looked like individual stones. Again, it's something that looks nice just sitting around as something decorative. I called him and he will see if he still has the plans for this or anything else. Chuck K. Quoting Bill Johnston <johnston@...>: This is a great opportunity to express an opinion that has been |
Re: Mini-Lathe Fuse
--Hi Pete,
Not sure where you can get fuses, other than micro mark or LMS, but they're probably available. What I wanted to say though, is you might want to consider changing the fuse holder to a better one that takes standard size fuses. I had problems with my lathe shutting off occaisionally, and traced it to the fuse holder. It had actually split in half! It's a real piece of junk! I put in a standard one of much higher quality and the fuse issue was solved. To me the stock one is so bad, it could almost be dangerous! Good luck.

Re: 1st Timer Accessories-Tool Bits (HSS vs Carbide)
G'day Rance.
IMHO and my experience I would use HSS paricularly as you intend to work mainly with brass. First you must get an bench grinder, 6 inch wheels as a minimum. Then get some key stock or square bar stock the size of you tool steel eg 3/8 square and practice grinding the different tool shapes. The MS stock is easier to grind than HSS and provides good practice and builds confidence. This is how I was instructed in the training shop; here we used HSS to cut really tough forged steel. Then get some HSS blanks, these can be obtained quite cheaply on eBay etc and grind up your own tools. My most used tools are a LH roughing tool and a round nosed tool which cuts both ways. I find an angle grinder good for removing a lot of tool steel, you also need a water spray bottle to cool the tool as you cut e.g. cut- spray-cut-spray. The cutting edge is then brought up on the bench grinder. I use an oil stone to bring a good edge. Whilst you can grind a parting tool from HSS blanks it is better to get a holder with a thin blade to suit, you get thinner partings, less stress on lathe, less wastage. The only carbide tool I use is a threading tool, I bought it because it was comparatively cheap from a local source. I hope this adds to the confusion! One good turn deserves another.

Richard posts here from time to time and has a web site with a number of interesting items. Consider carefully before building a quick change gearbox for the lathe. Most lathes with a gearbox offer additional gears to allow handling unusual threads. Plus, they often have additional gears and sometimes a special banjo to accommodate metric/imperial depending on the lathe's native system. Richard also provides plans for a fine feed module (see the 7x12 Files section) and for a banjo that simplifies setting up gears for threading. Rather than making a gearbox, consider making a fine feed and several banjos, one for each thread you commonly cut. (Assuming the simpler setup afforded by Richard's banjo isn't sufficient.) My approach is to use one banjo and try to use 32 tpi for most things I build - I do change the banjo's setup but not frequently. Of course, threading isn't a daily activity in my shop so your needs may differ. Martin Cleeve, who wrote the book on threading, seems to consider a gearbox a limitation rather than a feature...

Re: 1st Timer Accessories-Which 4-Jaw chuck?
G'day rance.
All you have been told so far is sound, if perhaps confusing. IMHO; chuck selection will depend on what stock you get. Round and hex stock only needs a 3 jaw self centering chuck, it will be the most convenient and have semi permanent residence on the lathe. You can even off set pieces for eccentric turning by means of packers. But soon you will need to face or bore an odd shaped piece, then its 4 jaw chuck time or even use a face plate. Ive had my lathe 10 months and haven't used the face plate yet but they are cheap and just worth having. You can get by with only a 4 jaw chuck but each job has to be set up rather than just thrown in the 3 jaw SC chuck. You will need a dial indicator and magnetic stand. If you are really clever you can use the cross slide and shims (cigarette papers) to get the work centred. Get the biggest chuck/s you can afford and swing in the lathe, remember the jaws sometimes extend beyond the perimeter of the chuck. You will need chuck and arbor for the tail stock, even if only to drill centre holes; this also means centre drill bits. You will be a centre for the tail stock as a minimum. A live centre is not essential, you just need high pressure molibdenum grease. I'll make some comments about tooling in a following post. One good turn deserves another.

building up ... (subject to other's differing opinion, of course). Working on the mini-lathe (even metal working) is not a hobby! How's that? What I find is that the people that seem most satisified with the mini-lathe (mill too for that matter) are people that have a hobby already and see the mini-lathe as a tool to fulfill that hobby. People that buy the lathe and than say, "What can I do with it?", will be unfilled until they get another hobby. I got the mini-lathe and micro-mill to make woodworking tools and woodworking accessories (knobs & pulls, for example). Woodworking is my hobby. But brass with the wood sure adds to the woodworking project. I bet just about everyone of you out there have another hobby that the mini-lathe is used to enhance. Let's hear what they are! Here's what worked for me. I used the lathe first to make accessories for the lathe. That way I learned how it worked. I started learning how to use a file. I spent a lot of time learning how to use a tap and die (not with the lathe). Than I started reviewing a lot of pictures of antique hand tools and picking out what I could make with emphasis on tools that I could use first and nice second. I'd say if you want to make gifts, start looking at gifts, in catalogues, stores, kitchen stores, etc. and see what you can make. Another idea, get some metal. Nothing like some brass bar stock (expensive), some drill rod in a variety of sizes, and some brass round stock in a variety of diameters to give you some ideas. Those ideas disappear quickly when you don't have materials. Also, consider, if you like woodworking, to add some brass to small pieces of expensive wood to make a project.

Mini-Lathe Fuse

So, what is the deal on these fuses? Are they a rare find or can I get them locally? Thanks, Pete |
