Can anyone give me a recommendation specificallybetween these two drill presses? Im curious if any one out there has used/worked with this Ellis model?(too many all in one features?) (spindle speed range up to 1200Rpms? enough for genral use?)Im looking at:Clausing 15 Model 1770AndEllis 9400 (drilling & tapping)
Reply:Another quick questions if anyones game
Obviously Im about to make a couple purchases
Who makes the best belt grinder (115v) under $1400?(used for heavy de-burring, and some intricate contouring & shaping)
Reply:first question..i see no problem with what you want to get as far as drill presses go1200 rpm...you'll probably never go that fast...second question..the belt sander...look on e-bay and you'll find most anything you need for cheap good luck...zap!
Reply:As far as the drill presses go I'd say go with the Clausing if you can afford it. I believe they are still made in the USA and are very good quality. Not familiar with that specfic model and no link ot be found here, but the machine does have to suitable for your intended usage. High speed operaton can be important for smaller drill bits, Aluminum and other non iron materials. On the other hand if you expect to bore large holes in steel los spindle speeds are the order of the day. In other words only you know what you need and there is no perfect machine.As for Belt grinders I would say forget about a 115 volt model if heavy usage is expected. The reasoning being you will want horse power to drive the belt and above about 1.5 hp you really need 220 volts single phase. So think a bit about heavy usage and intricate contouring, are they compatabile on one machine. The first thing I'd consider is an one inch belt sander, with a Baldor motor. Of course the companies name escapes me at the moment but you can get one for around $200 new and it is American made. These are usually between 1/3 rd and 1/2 horse power and are extremely handy for small work. For the heavy stuff that should be suplemented with a 4x72" inch belt grinder either purchased or made your self. See McMaster-Carr or other resources for parts or machines. I'm not sure you will get below $1400 new, maybe DIY depending on your resources. Search the web and you will find several approaches for DIY.Dave Originally Posted by smithjrAnother quick questions if anyones game

Reply:I would never worry about the upper end of the spindle speed range unless you're doing mass production. You can't really spin a drill too slowly, patience is more the limiting factor. The best drill press is the one that can be spun the slowest because it offers you the greatest flexibility in terms of bit size and type. You bits will also last longer if you spin them slow and that will save you money. Power feed is nice and will help prolong the life of your bits.
Reply:Thank you for the input, very helpful and appreciated!The tricky thing is that Im looking for a single machine to get stared out with (small personal shop).Im trying to figure/balance my projected usage, which is pretty diverse size/material-wise
Probably a lot of 3/16 to 1/2dia. mild steel stuff, but I do also project maybe using hole saws, alsobronze, aluminum, and stainless stuff. I know two machines on both ends of the speed spectrum would be optimal, but hoping to squeeze all my needs out of one machine. Again thank you for your thoughts.Regarding the drill presses here are two web links, to what I'm looking at:http://www.clausing-industrial.com/P...Drill15fot.htmhttp://ellissaw.com/DrillPresses/43/drill-press-9400Regarding the belt grinder
Im probably using it more for intricate contouring and less for heavy grinding. Thanks for the info.-J R Smith
Reply:Hi J RFrom the limited description of what you want to do a a quick blance at each drill press I would have to say that niether would do. The Clausing because the lowest speed is to high and the Ellis because apparently they are using a variable speed drive. My opinion of the Ellis could change if there was indications of differrent speed ratios available.My reasoning is this: hole saws require torgue and low speed. This of course depends on the hole saw size to some extent, but as you can imagine it doesn't take much to get the SFM up on a large hole saw. The other issue is the use of the machine on Stainless, low speeds are absolutely required here. Further you are likely to want to feed a bit faster.Now only you know what sort of holes you project to bore but my initial thought is that the Clausing will not go slow enough and the Ellis won't have the torgue.An interesting thought is to buy a Clausing with a 3 phase motor and put a AC drive on the machine. You still have the belt reduction for torgue and the ability to lower you speed by atleast half. Certianly not completely ideal but may work.************************************************** ********************As for the Belt grinder, well intricate contouring still covers alot of area. If you are starting a shop from scratch I'd still go for one of the cheaper belt machines to start. Kalamazoo Industries is the name I couldn't remember yesterday. Their 1SM and 2FSM are very handy sander to have in a metal wroking shop, especially for deburr and other light usages. If you take a look you will find that anything they define as a Belt Grinder usually has a lot more horse power. This results in a corresponding increase in machine costs. Please note that the HP ratings on this equipment is real unlike some of the imported stuff one sees.I'm not trying to sound like a salesman but this manufacture does make good quality stuff and you will find one of their smaller sanders in just about any metal working shop. Of course the larger machines are more special purpose, but it does sound like they have something to fit your needs. ThanksDave
Reply:Baldor makes good grinders. I can't get on your web page at the moment to point any out.
Reply:I have that model of Ellis drill press and absolutely love it. Torque has not been an issue. For what you describe of your intended use, it will be more than adequate.
Reply:Thank you for the input. It is all very apreciated and helpful! i am going to order the Ellis tomorow.Thank youJR Smith |
