Re: First prototype of the laser edge/center finder done!
Jeff Demand
John,
If you are looking for 11.4mm x 5mm button cells (**357, **44, *76 depending on the chemistry and drain) Radio shack sells 6 volt "n" sized batteries which contain 4 cells. They might even offer the choice of alkaline or silver oxide, it's been a while. Not as cheap as your pointers but might be fresher.

Malcolm Parker-Lisberg
A much smaller centre finder can be made by removing the laser diode and mounting it at the end of perpendicular crossed flexures, rigidly mounted at the other end. Only two adjusting screws are then required, set at 90' to each other, giving independent X and Y adjustment, as the non adjusted setting screw slides across the flexure as the other screw is adjusted. The lasers in the cheap laser levels have push on push off switches and brass mounted laser diodes rather than PCB mounted diode. This has been on my 'to do' list for two years.

Store :-) These stores have slightly differing names but they're common now. Sometimes they keep the pointers behind the counter and you have to ask for them. The pointers include 3 batteries of the type used in my DROs so the pointers are slowly accumulating in my shop... John --- In 7x12minilathe@..., "rancerupp" <rupps@...> wrote:

Here's a kit that replaces the spindle gears with metal gears. The gears

Re: Rocking tool post shim
Yeah, I'm sure it is not, but I just thought that a Woddruff key might be used as raw material if one was so inclined to make your own rockin' holder. I use carriage bolts to make old style squre-headed bolts by turning off the rounded head, without using a mill (which I don't have yet!). Just thinking out loud. Ron. Keep makin' those lovely chips!

HF - Special Order - 8x lathe
druid_noibn
Hi All,
It seems HF made it official ¨C you can buy the 8x lathe 44859 as a Special Order item though their stores. Several members noted they were able to do this using the 30% of coupon. My local store said no a couple of weeks ago. I was told (e-mail) that "The special order program was offered for a limited period only." I am not sure what HF is up to but, it might be interesting to keep this in mind. Maybe HF will list the X3 mill and maybe, just maybe, a good coupon will also be available. On a separate note ¨C Cheers for HF ¨C after 20 weeks, they said they actually shipped the replacement screws for the lathe rests purchased Sep. 06, delivered damaged in Nov. 06. There is potential here <smile>. Take care, DBN |

Re: Broke the tap, Grrrrr.

Hi Vicky,
Sorry about the tap,but you did learn a valuable lesson concerning cheap tools.. I have an ulterior motive for replying to you! Where did you find the design for your centre finder? Thanks and regards Mick. Victoria Welch <wrlabs@...> wrote: Just to share the fun. Got my laser edge / center finder holder all turned and bored out and started drilling and tapping (4-40) for the set screw / power switch holes. Went along nicely up until the final one (9th) where the tap broke. Nothing gets it out :-(. And of course it is one of the lower (critical) ones :-). I tried the 4-40 tap out of my little kit from the auto parts place and it promply turned itself into a corkscrew :-). Broke too, but it was soft enough not to shatter and I was able to get it out with vice grips. Sigh. I suppose that this isn't a real big deal since this is a "proof of concept" thing and I can rotate the holder 45 degrees and put in a new set. Lessons learned: When wrists get tired from doing the tapping - take a break rather than switch hands and cheap taps are a total waste of time and money (now I know what a cheap tap is :-). Only a minor setback as I now have the holder itself worked out and can easily enough duplicate it. Not a bad day!

Re: Broke the tap, Grrrrr. (Drifting OT)
Hey here's a laugh for you. I dropped into the local Bunnings

I bought my Frost taps from there the other day, good price. (Frost are OK quality) In SA the Bunnings stores have a tool section with its own checkout partitioned off from the main store . I have bought a lot of things from there eg the AUD13 drilling vices, reasonable quality drill bits etc up to my bench grinder and drill press. They don't sell "engineering" tools. You had better get used to Bunnings, they are owned by West Farmers who have made a strong bid in for Coles! One good turn deserves another. Regards, Ian |

Re: Broke the tap, Grrrrr.
Hi Ellis,
Naw. If you knew Bunnings you wouldn't even ask for a self cutting tap. Even the thread cutting kind was a long shot. But I could sure use a skyhook next time I get my 4WD stuck in desert sand with no trees to winch off for a hundred miles! Got any 4 ton ones?

Re: When is a Sieg not a Sieg? THE DIFFERENCES MATTER
G'day Gavin.
I bought my lathe from Taig Machinery P/L in Canberra. A complete package including steadies, 4 jaw chuck, TS chuck etc was available for AUD920. Freight to Adelaide was AUD75. Roger of Taig Machinery commented that he was having difficulty getting the same quality machines for subsequent orders, other than that he didn't offer much more information. Whilst my machine looks like a Real Bull, who knows? Colour seems important to some, mine is a businesslike mid green, very pleasant to look at! BTW Ozmestore are noW selling minilathe packages for AUD598 which includes face plate and 4 jaw chuck but no steadies or TS chuck. I have bought a few things from them and they are OK but don't like you walking in and looking at things. Had I waited until now I could have bought my lathe from them and saved about AUD300. But would I have had the quality? Maybe you should contact Taig Machinery "k1ergo@...". One good turn dererves another.

Re: When is a Sieg not a Sieg? THE DIFFERENCES MATTER
G'day John.
My lathe does look like that, sans guards. I do have a chuck guard but it has the pivot point raised to clear the 90mm swing. Regarding your other question, there is so much other mess on the floor of my workshop the droppings of the real bull go unnoticed. One good turn deserves another.

Re: Broke the tap, Grrrrr.
Victoria Welch
Hi Folks,
Well, I did get the broken tap out! Since I had to bore out the holder more, it had to go. Was going to drill all around it with small drills, that did not work out well with the tiny carbide drills in the drill chuck, I really need a 1/8" collet. That and it takes a VERY delicate touch, hit the tap while trying to drill beside it or too much pressure - SNAP. After about a half dozen I decided to see what else I had in the Harbor Freight assortments... I found I did have one bit about the size of the tap and with a very light touch and SLOW feed I was able to start it in the tap. Spritzed it every so often with WD40. Took a bit but was able to drill through it and then just flick the leftover pieces out the bottom. Success! I was able to bore out the holder without messing up the boring bar any worse. Cleaned it up some on my roomies diamond faceting lap but it still isn't quite right, needs more work. Probably need something finer than 60 grit :-). Hopefully there will not be a next time to experiment with the alum :-). All's well that ends well and I learned a bunch in the process! Thanks to everyone who contributed so graciously to my mental tool box on the subject!
