I have a queation about this article, maybe someone would be kind enough to explain. 1. The tool post is lowered by 1/4", but the new base plate is 3/8". I...
Rich In going back over the article your interpratation is as good as mine. My thought was to use a split cotter as the locking factor rather than splitting...
Absolutely, I looked at it as an idea that raised some questions in my mind. The mod I have in mind is the SB style you mentioned. But when I look at a...
My HF 7/10 lathe started not coming on when I turned the switch on. I checked all connections. Then it started running full speed when I turned it on ,in...
... When you say you replaced the speed control, do you mean the entire circuit module, or just the control knob and associated potentiometer? What you...
I only replaced the forward and reverse switch, and the potentiometer. Is there anyone who knows how to check the rest of the electronics,so as I might isolate...

I saw an article posted somewhere from an old Model Engineer mag about making a back gear attachment for a 9 inch lathe. It used internal backgears in a ring...

It would be interesting to try to adapt planetary gear reduction to the rear of the spindle of a Mini lathe. The motor would have to be relocated or a counter...

... Gordon, My family recently presented me with a Homier 7x12 and I smile a lot now! The speed control allows stable speed down to nearly zero. By observing...
When it cools off I will have to start checking transmission shops and junk yards. Gear reduction would sure make threading easier. Remounting the motor or...

Gordon There are pictures of Richards speed reducer jack shaft in the photos. JWE Long Beach, CA They define a republic to be a government of laws, and not of...
James, A jack shaft by it's self doesn't have the torque at low speeds of a planetary gear, the belts slip. Although a timing belt should be better. Of course...
Mert, This article was what got me started thinking about it in the first place. Considering the problems with the increased torque on the gear train I think...
Hi I have a chinese built 12X36" machine, so it is a bit bigger than yours but it still needs a lot of work to make it perfect ;) The standard 3 jaw chuck that...
Hi Ben, A standard 3 jaw can easily have 3 thou runout when new. There are Set-tru style 3 jaw chucks that have a body that can be adjusted on the backing...
Greetings again. Just remembered something from my Chinese chuck days. Tear the entire chuck down and clean everything. There was some swarf in the 3 jaw...
... I've looked at this idea a bit myself. Among other things, I found that there are a number of small planetary reduction systems made for (of all things)...
Originally I put a piece of 2" bright in the jaws right at the back (less than ideal I know) to load the jaws up, then after doing that I moved the piece to...
... But remember they are typically reducing something over 20,000rpm to something slightly more reasonable. Transmitting the same power at 2000rpm involves...
... The real "Mert" <G> would most likely advise you to use a hand operated crank if slow speed is wanted for threading! That would also be my choice. Richard...
I would say if your 3 jaw is now within .002, that is excellent! FYI from a couple sources: From the J&L catalog,8" 3-jaw chucks made by Buck ($1400) and...
1-3 thous is expected runout for a 3-jaw, non set true, type chuck of decent quality. Any more precise requires a Quality 4-jaw, or a collet chuck. Hardinge...
