Thanks John and Perry, I found myself musing about a small Mill-Drill, on the theory that it must have better sleeve bearings than the typical Cast Iron that one finds in low-end DPs. Then I reconsidered; I could be buying the Worst of Bad Choices in both cases! I'm in Fort Lauderdale, Florida...

Hi all, My inexpensive, 1/2 Delta DP has had it, and I'm tired of spindle drift. I don't see a way to cure the problem other than replacement. I would appreciate any recommendations for a good reliable machine suitable for a retiree's financial resources and modeling interests. :) Many thanks...

Thanks to all, and to wrap this matter up, I puchased a 35mfd 370VAC Run cap at Graingers. Its biggish, didn't fit in the original container, so I strapped it in place in the slipstream of the fan, against the motor casing. Its a little too soon to tell , but it seems happy there. Thanks again...

Thanks N4, that is just exactly the info I was looking for. The caps have No exposure to the ambient, and are encased in plastic containers right on the motor case, as is customary. The fan is in a cowling which directs a laminar flow over the case, and I suppose that is enough to control the...

Hi Guys, Many thanks to you all for your kind advice. The motor uses two capacitors, for Start and for Run. In both instances, the Run capacitor has failed. The Run Capacitor is of 'film' construction and not polarized. The replacement which failed was ordered on-line, and although I knew better...

Thanks Steve, I spoke to them and physical size was an issue since the original has a tight plastic cover. I'm coming around to the idea fabricating something in its place to shield the terminals.

Hi All, I have the 8x12 HF lathe and have had the original 35 Mfd 250VAC Run Capacitor fail after 2 yrs. The replacement [which I may have improperly spec'd] lasted one week. Failure seems have to occurred with a fairly heavy load at the lowest spindle RPM. I'm hoping that someone has a source...

Hi DG, Nice work on your milling attachment. I have an 8x14 HF Lathe on which I have adapted a very old Atlas Milling Attachment. Its a rugged piece of cast iron to which I have mounted a 2" screwless machinist vise. I find on my machine that roughing end mills up to .375 dia. work very well...

Hi Rick, I have learned to grind my tools to achieve satisfactory finishes on most metals including SS. What I haven't learned to do is to grind the tool geometry to break the string. Your post is timely as I have been thinking about this exactly and i'm wondering if you have an suggestions.

Many thanks to all, The VFD is far and away from what I was thinking, and a three phase solution was the furthest thing from my mind. On further inspection, it seems that the terminal block burnt up, opening up the circuit. I am sold on the VFD approach, particularly since it seems to deal...

Thanks to all, I am not familiar with the term VFD, but I suppose that it is some from fractional wave control to be used with a standard AC motor. Am I close?

Hi all, I have had the HF 8x14 lathe for about 2 1/2 years and its a great machine. Recently I have been having motor problems which could be the motor itself, the connectors and terminal strip, or both. I'll probably have to change the terminal strip and crimp on new terminals to identify the...

Fred, I've had that problem in the distant past. In some instances it can be a starting capacitor. In other cases, I have found it to be a function of the starting winding which allows the motor to start under a load. In the latter case, a centrifugal switch generally is used to engage the...

Beautifully done, Ken. Given a week or so, I might equal a part of your output, together with a fair amount of casualities.

Very nice Paul. I did something like that some years back when I was building a small .250 /.500 double acting wobbler. The engine runs well as is, but your approach and the final result has a lot more artestry and appeal.

IMHO, the chip backstop is a must. You could also consider adding a hinged top. From to time I have let my swarf grow to an almost unmanageable level until I dealt with it. Lately, I have begun using a sheet of newspaper in the tray beneath the lathe and dumping it after each days work. It...

Hi All, A month ago I was obsessing over an engine line-boring problem, and Harry was kind enough to redirect my efforts to a more feasible approach. As anyone will see from the attached photos, my setup less-elegantly approximated Harry’s excellent CAD drawing, which is in this string. The...

I've used them on hard ceramic tile and they cut a neat hole like butter. Brian

Lathe Nut, Here's a reference table that should help. http://www.engineershandbook.com/Tables/threadlimits.htm brian

Thanks Kel and Bogs, Enough said, It's off to the store I go. Brian
