Paul De Tourtoulon Posted February 1, 2022 Share Posted February 1, 2022 I have an Emco Sl mini lath and I have also been looking for another lathe of lathe / milling machine,and the prices have put me off as well as getting no sense from the sellers as where I can actually see one, on my lathe they do a post and fixation to turn my lath into a mini miller, then I thought either I could fix my lathe onto a simple pillar drill ( get where I am going ? ) but as I have a simple Bosch pillar drill why not turn down the pillar on it to fit into the stock end of my lath at the place of the motor and use the drill as the milling motor,,, Meanwhile I am looking for a small vice.

Simon Chaddock Posted February 1, 2022 Share Posted February 1, 2022 Paul De T The problem in using a pillar drill head for milling will be a limited spindle rigidity. A twist drill is basically a self aligning cutter so the drill spindle and its bearings do not have to resit high side loads. Milling is the opposite so the spindle and bearings have to be much more rigid to prevent cutter chatter. You would likely find a drill head set up would be limited to fine cuts and using only very sharp cutters but within such a limitation it could prove acceptable.

Paul De Tourtoulon Posted February 1, 2022 Share Posted February 1, 2022 Yes thanks Simon, it is an old sturdy Bosch drill ans as I will mainly be machining aluminium and plastiques for model planes, ie engine mounts etc, for the bigger stuff a club member ( he is currently doing the work that I posted earlier ) He has 2 lathes and a decent sized milling machine,,, Quote Link to comment Share on other sites More sharing options...
Martin Harris - Moderator Posted February 1, 2022 Share Posted February 1, 2022 Another problem with attempting to mill with an adapted drilling machine is that most don’t have a drawbar or provision for one. The interrupted cutting action is likely to loosen the taper holding the chuck… Quote Link to comment Share on other sites More sharing options...
Paul De Tourtoulon Posted February 1, 2022 Share Posted February 1, 2022 What's a drawbar ? Quote Link to comment Share on other sites More sharing options...
Eric Robson Posted February 1, 2022 Share Posted February 1, 2022 (edited) Hi Paul, the drawbar is a long bolt that goes from the top down the centre of the quill and holds the chuck or collets firmly in place, I have a small mill and sometimes if it is a small job like cutting a groove in some wood for an undercarriage fixing I put the cutter in the chuck, for cutting metal I use the collets to hold the cutter. I also flew on Newcastle town moor many years ago. Edited February 1, 2022 by Eric Robson 1 Quote Link to comment Share on other sites More sharing options...
Robin Colbourne Posted February 1, 2022 Share Posted February 1, 2022 (edited) 24 minutes ago, Paul De Tourtoulon said: What's a drawbar ? It is a long bolt which screws in from the top of the quill to pull the chuck or collet into the quill. By being in tension it prevents the chuck or collet loosening and dropping out if you experience chatter on the cutter. A vertical slide is the usual method for converting a lathe to do milling. It enables three axes of movement at the cross-slide, so you mount the workpiece there and have the cutting tool fitted in the headstock.

Paul De Tourtoulon Posted February 1, 2022 Share Posted February 1, 2022 Thanks, I have looked up all the new words to me for a milling machine,, all double dutch to me,,,? I have a box of 10mm OD collets but no holder, so I will make one up myself, and as my friend rang me that he has turned down my pillar drill's post to fit the engine bed, "maybe" I will make a steel piece up to put the lathe motor on it as it has splines on it tu lower the tool, I haven't got the lever but if I could find a metal gear wheel,,,,, Off to collect it, and look around for a small ( tiny) vice to adapt to it. Ps, All I really do is make and modify retracts, undercarriage legs and engine mounts so no need to spent a couple of grand on one,,, Quote Link to comment Share on other sites More sharing options...
Engine Doctor Posted February 2, 2022 Share Posted February 2, 2022 (edited) Hi Paul . If you intend using a pillar drill as a mill be aware that the cutting action /vibration of a milling bit can make the drill chuck loose in its taper hence a draw bar to hold it firmly in place. You may also find that the bearings fail rapidly as they are not designed for side loads as they are on a mill.

Paul De Tourtoulon Posted February 2, 2022 Share Posted February 2, 2022 Thanks,, I found a small vice yesterday and am making some pieces up to fix it to the chariot ( ? ) I milled it using the tool holder and 3 jaw chuck, not a good idea I put the cutting tool into the small drill chuck that came with the lathe, and there it didn't move. A shame I have so much rubbish an Emco 8 has come up for grabs at 600€,, just the job ! Quote Link to comment Share on other sites More sharing options...
