Brilliant idea to turn your lathe into a generator! Just apply electricity to the commutator and then harvest power from the plug. Handy if you don’t have, errm, electricity. Begin forwarded

Here's one I bought some years ago on eBay. I cannot find a better picture of it. Peter Brixey in sunny Florida.

You may be able to put some brass shim under the headstock if it is low relative to tailstock centre. John

Take the way bars off and check them for straightness? Maybe try them the other way up? Or even turn one around? I’m not an expert on this, just thinking of easy things to check. My first thought

Another good point but I can't get over the description of the hole angling down. If the workpiece is in the headstock chuck there is no such thing as down. I can see getting a tapered hole but not an

I was thinking the same thing, bum drill-bit.? With a headstock/tailstock miss-alignment he would have always been turning tapers.

Good point Quinn, I've seen a number of new drill bits from Harbor Freight where the lips are not of equal length. This will cause a bit to wander. One visual clue of this condition is different

I am presuming the drill was mounted in the tail stock. If you can duplicate the set up, and the drill wanders downhill, repeat the set up and rotate the drill 90° and see if it wanders in that

Part of the secret of Gun drills is the cooling. Not only does it cool the tool tip, but it aids in the removal of the chips. It is the buildup of chips that contributes to a twist drill wandering.

I have seen references to people adapting the Sherline thread cutting attachment to Taig lathes. Not sure how practical it would be to try and make it work on a Unimat.

A downward slant suggests a vertical misalignment. That is difficult to adjust on the Unimat as they are not designed for vertical adjustment. Also, there are several places that may be causing the

Hello Dick: As a tool maker I bought two Brown & Sharpe Best Test indicators, the first is 0.0005" and cost me $35 in 1973. The 0.00005 cost me $100 in 1977. They both still work great. Carl.

Hello, Keith, Yes, gun drills can produce a very deep and accurate hole. They have coolant holes in the ends and are usually used with coolant or oil under high pressure. We drilled deep waterline

Hello Carl, Where did you get the 50 millionths indicator? That is quite a close resolution to be using on a Unimat! Dick -- http://www.homemadetools.net/ forum/ OFF-

For those wondering about the significance of the X and Y capacitors, they are specifically designed for use in safety critical positions. X capacitors can withstand high voltage pulses without

What diameter hole was it? If it was relatively long you need to make sure you have a good quality drill. For very long holes you might need an unusual drill type - I think worm drills can help, also

were you rotating the workpiece against a non-rotating drill? If not you should try it.

Thanks! My problem is I was drilling thru a brass rod to make it a fuel tube for an SU carburetor. It was approx 2 inches long. I started with a small pilot, but as I moved up in size I noticed it was

Hi there, The X1Y2 class capacitor in the datasheet can be purchased from this ebay seller:?MIFLEX KSPPZ-10-2 Capacitor Indulgence Capacitor Radio Interference Capacitor for LED | eBay | | | |

I would be sure to replace that cap with one that is specifically rated to be placed across the mains.. The PN below is available from Mouser, etc. 0.01 uf + 2x 2500 pf @ 220V HPF 65.8 wrote:
