Be very careful with the quill on these machines. It WILL drop when you least expect it and take a gouge out of your job. Make sure it is physically pushed DOWN before you tighten up the quill lock, and this needs to be done between cuts. There are a few mods about to cure this problem, and they usually concern a weight and a pulley to counteract the weight of the quill, so effectively pulling it UP all the time. Just be careful.

As Bogs has pointed out the quill dose drop on these machines ,giving a poor finish when boring and worse if you are doing an intermittent cut ,say cutting a radius on cylinder saddle using a boring head and down feeding the quill. The cutter will move up as it comes in contact with the work and drop as it leaves :bang: So the quill needs to be loaded up so that it is always in contact with the quill feed pinion. Mods done to my RF25 MILL/DRILL ,,,spring attached to collar on quill ,fed up through the head casting and secured to the belt guard .. Sorted . Got rid of the two nuts that lock the head , fitted two levers ,,,Replaced the small lever that locks the belt tensioner with a T bar ,,, and fitted lever to motor mount plate to make belt tensioning easier.

I haven't seen it done that way Rob, nice one. I forgot to mention in my last post, if you do such a mod as Rob has done, there is no need to do what I said in the first part, about making sure the quill was fully down. Bogs |

Its been 6 years since ive used mine but i cannot honestly recall seeing the quill drop in over 4 years. Reason i always put tension on with the quill lock when winding the Z feed. If a heavy cut i will tighten up the quill before putting a cut on. |
