drill holes in tubing
I spent the day getting a used greenhouse home. I'm plumb wore out right
now. So, I'm a dreaming on the re-construction. I'll build it on skids so I can drag it to new ground every year. To do this, I'll need two runs of square tubing on each side. Fifty spots on each side to drill a 1.9" hole for a total of 200 holes. Then weld a vertical sleeve at each hole. The base on the sides will look just like a ladder laying down. Anyway, what would you use to drill 200 1.9" holes in 2-1/4 (if made) or 2-1/2 square tubing. I have a radial arm drill press. I know I'd go through SEVERAL 1-7/8" regular hole saws. There must be a better option. Karl |

Anybody know about annular cutters?
http://www.mcmaster.com/#6849a48/=43qybf I have a huge Jacobs chuck. Most drill shanks are not hardened. Could I cut the shank down on this cutter to fit my Jacobs chuck? Karl |

Karl So what worked the best for pulling the conduit out of the ground? I would cut the holes with a oxy/acet torch because that is what I have. Make some sort of jig to guide the torch and also to guide a drill to speed up starting the cut. A 1/4 inch hole or ever somewhat smaller would be enough. Yeah you can piece with the torch, but it is a lot nicer to start at an edge. It speeds up the heating as the heat can not go in all directions. Dan |

why are you drilling holes rath r than just welding the sleeve in place? it
seems like a lot of extra work - a good weld is as strong as the metal it's attacing to "Karl Townsend" wrote in message anews.com... I spent the day getting a used greenhouse home.

Why not use some 3/16 by 2 inch bar on each side of the sleeve. That would be close to tubing, just no top or bottom. Ought to pull okay. Would not work for pushing. Dan |

I just tested the shank on a couple Rotabroaches and they're hard -- more like an endmill than a drill. The Rotabroach shank is a standard 3/4" Weldon. I've seen Morse taper adapters for them but can't recall where. If you don't have a 3/4" chuck, a reducing adapter would be easy to make. I usually drive them in a collet in the mill. I just noticed these on Hougen's site, but I have no experience with them. http://www.hougen.com/cutters/sheetm...olcutters.html -- Ned Simmons |

How about a number of brackets that have holes and they get welded.
Z like brackets. Something like building tie downs. If the holes waller out over time, then the bracket can be cut out and a new one put in place.

Treated would last longer than the steel. And it would drag easier. Drill your holes using a 2" Forstner bit. Then drill in on an angle and use a screw to secure the tubing to the steel. OR Gorilla glue it in. For the floor the easy thing to use is horse mats. Why drag it to new ground? The idea with a greenhouse is that you use compost and good soil in beds to raise plants. No real reason to move it. -- Steve W. |

Karl, your CNC plasma machine consists of two parts: 1) Plasma cutting power supply and torch 2) CNC controlled table. Item 1 separates from item 2 and likely can be used manually, with especially great success if you use a jig. I would do just that if I were you. i |

Iggy -
Not so easy to remove the torch cable from the table. I bought a 50' torch upgrade to a higher power and that works great out in front of my shop or inside. I have a clamp on ground to the main return clamp (which I changed to a 200amp clamp) and it runs 50' (nice big stick wire) and I have a magnet attachment. I can swap ends if a clamp is needed. I have a table and CNC plasma machine as well. Removing it isn't bad - just not easy to do back and forth...

What is a Smith 55-T plasma torch worth?
I bought this some years ago and within 6 months Smith was bought out
and the supply of consumables has pretty much dried up. I'm looking to sell it and replace it with another torch. What would be a fair asking price? It has quite a few consumables with it, but the long nozzles that I liked so well are gone, burned up the last one yesterday. |
