Harold, this is an excellent design for use on lathes where tool position repeatably is extremely important such as in instrument making and other tight tolerance machining. By the way, I have been using your books and following your website for years, and wonderful to see the videos. Thank you for taking the time to post this and your other works. Regards, Paul Jones

I have built this tool holder and have found it perfectly adequate for my uses. My version is far from perfect, but the design is very forgiving.

Hi Intent to inform: I made one from some/your plans, be aware that the excenter plug has a way to thin wallstrength with +-1mm. I broke min off after the 1. use. As seen here in the clip your excenter grabing plug is at least 12mm thick. The whole system is very regit besides the somewhat misleading plans spec, it is a very good design.

Nice explanation Harold. You might consider adding the direct link to the notes under your video.

Good Day Sir..... I would like,to ask if this design can be used on a much bigger lathe...... Scaling up all the features.......

@homemetalworkingworkshop3365 6 лет назад

Very sorry Hendri for the delay in replying but I see no reason why it could not be made larger. If though you were to do a true scale, say 1 : 1.25 you may end up with complex dimensions. I would chose the size for the base and the holders and then design it around those two sizes. Harold

Exceptional design

Thanks all for your comments. Unfortunately though, at 84 (2017), I now find it necessary to limit my involvement in my website and videos as the brain is not as agile as it once was. However, should you want to contact me, use the contact page on my website, here, www.homews.co.uk/page6.html . Do please read my comments there before posting. Harold

I like it :-) Nice sensible design. The only thing that would bother me, is the need to use a separate tommy bar . Could you not redesign the cam , so it is operated by a lever concentric with the mounting bolt?

@homemetalworkingworkshop3365 7 лет назад

The answer Bill is of course, yes. However, whether it would be as easy to make is doubtful but without having done the design I cannot of course be sure. Ease of manufacture is though a major factor in the design. There is nothing to stop a workshop owner modifying the QCTH, as some do for many of my designs, even this one. For me, I have spent very little time in the workshop in the last five years, and at 84 I would like to start making things again, be it metalwork or cabinet making, my preferred pastime. Myself, I do not have a real problem with the Tommy bar approach, other than to say, I am considering having two holes at right angles for the bar giving more choice as to where the bar is inserted.
