Big taps?
I'd like to buy this, that, and the other, but money is tight. I'm thinking
of lots of things I could fashion some reasonable approximation of for myself, if only I had some way to thread something to fit on my spindle. I have a JET mini, so I guess that's 1"-8. I don't have a tap anywhere close to that big, and I don't think I've ever seen one. Is it as simple as finding a machine tools catalog or such online and buying a big tap? Can you actually tap wood acceptably with a metal tap, or should I be thinking along different lines? (Most of the gadgets I have in mind to make, like a screw chuck, would be fashioned out of wood.) -- Michael McIntyre ---- Silvan Linux fanatic, and certified Geek; registered Linux user #243621 http://www.geocities.com/Paris/Rue/5407/ |

Big taps?
Just use a 1" - 8 tpi nut! While I've not ever found one of these at a
Lowes or Home Depot, I find them at all the ACE Hardware and semi-local hardware stores. What I do is take a block of wood (hard maple is my usual choice) about 1" thick and turn it round. Then I turn a little recess about 1/2" deep in it that the nut will fit into snuggly. I put the nut in there and use a good glue (polyurethane is fine) to keep it there. NOTE: Don't get the glue in the threads! It'll foam up but I just cut that away. Put that nut/wood on your lathe and true up the face of the wood. For a glue chuck, I glue another piece of wood (again about 1") onto that 1st piece of wood. This wood is my waste block wood. I can do whatever I want to with that and just replace it when needed. To make a screw chuck, I simply bore a hole in the wood through the center of that nut and use a modified bolt. You can glue it in or just leave it free spinning along with a lock-nut so it'll tighten down good and not spin. You could make small faceplates or just whatever you want with this arrangement. I think I paid under $2US for the nut. I got this tip from a club member and it's worked great. Yes, you can tap wood but it'll need to be a hard, tight-grained wood to work at all. Personally, I wouldn't trust it but I know of several turners that do and have for a long time. - Andrew "Silvan" wrote in message ... I'd like to buy this, that, and the other, but money is tight.

AHilton wrote: Just use a 1" - 8 tpi nut! (clip) ^^^^^^^^^^^ I do that a lot, using epoxy to hold it. You can make wooden faceplates, vacuum chucks and jam chucks. I usually start with a hefty piece of wood, and keep turning it to suit individual projects. When it starts to get thin, I just add another slab of waste wood with Elmer's glue. And I have a few different shapes lying around, so I always reach for the one which requires the least modification. ^^^^^^^^^^^^^ Silvan wrote: (clip) Can you actually tap wood acceptably with a metal tap (clip) ^^^^^^^^^^^^ You can, but, as Andrew says, it works best in hard wood. Some time ago I was the successful bidder on a lot of 1" x 8TPI taps, and if you had been around at that time, I would have gladly sent you one. Now, I have only one left, which I am keeping it. |

No experience with these folks, but I have them bookmarked since they're one of the few that offer 1x12 taps: http://www.hhip.com/products/product...ctID=1011-6002 |

Big taps?
HI,
If you have an industrial fastener outlet near you, you can buy a 1" X 8 TPI grade 8 bolt and cut triangular reliefs at several places around the end so that it cuts like a tap. It can be used on hard woods, aluminum and copper. Since it already has a hex head, it makes operation with a ratchet or box end wrench easy. You should be able to get a short one for a couple of bucks. This should take you through occasional use. If you expect to do a lot of this, you may want to go ahead and spring for the tap and have the hardened cutter that should last a life time threading wood, unless you work some of the high silica woods like mesquite. For a good selection of taps you can try places like MSC. Ken Moon Webberville, TX ******************************************** "AHilton" wrote in message ... Just use a 1" - 8 tpi nut!

Try Ebay. I just got two 1 1/4"-8 taps. They cost me $3 and $9 +
shipping. You just have to be patient and spend some time going through the searches. I prefer the Tap approach. I've gone the route of making face plates with nuts, however, I had to have a friend cut an internal recess in the nut so it would seat tightly on the spindle flange.

Peter Teubel Milford, MA http://www.revolutionary-turners.com delurking for a sec Well, here's two separate auctions: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2588300733 1" x 8 bottoming tap (this is what I have and it works extremely well) and http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2589190648 1" x 8 plug tap When I did my search, I looked in the Business & Industrial Metalworking Cutting Tools, Consumables Taps category and found them there. You do need to use a fairly good hardwood for the threads to hold decently. Poplar works ok, I'm sure Maple would be great (I've got a stack of 3" wide Goncalo Alves boards that taps like a dream), anything softer than Poplar just shreds. Make sure the grain is perpendicular to the lathe bed though, I haven't had much luck trying it the other way. - Mike -- Natharias at lycos dot com |

I didn't see 1.25" listed, but the way I found those was by going to the category (Business & Industrial Metalworking Cutting Tools, Consumables Taps) and doing a search on the number 8. Brought up a lot of unrelated taps, but the results were less than a page long. Doing a search on 1 ("1 4",8) (tap,taps) (everything between the 's) in the Business & Industrial category brought up 2 pages with a selection of 1 1/4" taps (Ebay makes these kinds of searches difficult cause you can't do a search with a slash in it), but none in 8 TPI. A bunch in 12 TPI and 7 TPI, but not 8. possible search terms would include: 8, 1.25, "1 4", "1 1 4", "11 4", tap, taps in whatever combination nets the most signal with the less noise. (it's a little wierd, but doing a search for "11 4" will bring up anything that reads 11/4, "1 1 4" - 1 1/4, "1 4" - 1/4) - Mike |

Grizzly has threaded inserts to fit just about any spindle. One for your 1" x 8 RH is $6.95, and has three holes through which you could bolt or screw just about anything. Max |

Probably just lucky that I found it. It was a bottoming or plug tap which is fine for wood but if I had bought it for metal I would have been up the creek without a taper tap to use first - never dawned on me to check what style it was. You are probably aware that 1.25x8 is not a the standard nut and bolt thread - I think 1.25x7 is the standard coarse and 1.25x12 is the standard fine. Seems that a lot of machines use the 1.25x8 so it is not exactly a real odd-ball. I believe the word "specialty" was used in the description. Billh |

I used the 1 1/4-8 and restricted the search to business and industrial. Then I forced Ebay to display pictures and just browsed through the listings.
