First time doing a little project using my new and fake Dickson quick change tool post, bought from HBM machining. I mess around with the lathe a bit trying to make a spacer washer. And even manage to screw that up a bit. But at-least my modified parting blade holder works great as a boring bar holder. :)
FYI: I am trying to make a some money for my youtube hobby through the Banggood affiliates program. Follow the link below, buy something you NEED, and I'll earn some commission. Doesn’t cost you anything extra and you're basically taking money out of Banggood's pockets and putting it in mine :)

I have the same type of QCTP - really like it, and have made some extra holders for it

I'm old school I still prefer my 4 way toolpost. Even the very best QCTP are a fair bit off center from the center support bolt and never inspire confidence in me with that length of overhang especially with interrupted cuts. I hve a QCTP and it spends more time in it's box than on the lathe,

Hey Moe, that was some great camera work done by Larry and Curly! I definitely now know which QCTP not to buy.

When using calipers to measure the inside diameter of a hole, always tighten the hold down screw before withdrawing it and reading the measurement.

"I had my first good idea in weeks!" Hmmmm.. I have them less often than that! Another very entertaining video, thanks. I recently dumped my 4-way post for an AXA wedge type QCTP and it's my favourite thing ever. If not for my wife's intervention, I'd sleep with it under my pillow.

I have an Aloris style Quick Change Tool Post, mine is a wedge lock style. Mine appears to grip the tool holders much more rigid than your Dickson Quick Set knock-off.

I had one about that size on my hardinge . It worked ok but was simply not strong enough, i kept breaking the clamping nut ( it is pulled in by the eccentric clamp bolt) . I stll think you need to raise the block up , the clamp needs to fit in the middle of the tool holder (you should check the clamp nut for fractures - push it in while pulling the clamp bolt up, watch where the spring goes!).

A few things. You need to make a sleeve for the centre fixing (compound bolt) or get a bigger bolt, so it's a tight slip fit. Otherwise the QC holder is going to move around and give you chatter. Also, think about using the hole in back corner to fit a taper pin that keeps the QC block square. Mine has a tendency to swivel out of square when only held by the centre bolt, especially when taking heavy cuts. I've found that the tool holders will have a tendency to tip (like your parting blade did) if they're high in the QC holder. Try shimming the holder itself, so that tool holders are lower into the QC holder, but still on centre to the work. I have one of those skinny parting blade holders. The blade breaks every time I try to use it, because it's so thin it flexes under pressure - my advice is to throw it in the bin.

Coming along nicely. Seems like the Dixon is better matched with a smaller lathe mind you :)

It appears that the quick change tool holder is way too flimsy for the kind of work you do. It’s good to see it’s limitations and the negative effect it has on your objective. To know what doesn’t work is nearly as important as knowing what does and I’m sure this will help others in deciding what to buy.

May be you could make a boss to sit under the tool post like you 4 way has, may give a bit more rigidity worth a try.

I would've thought about putting a riser under the toolpost, that way you could've kept the parting holder as it was.

Ik heb dezelfde toolpost en ben er meer dan tevreden mee. Het valt mij wel op dat je nogal veel materiaal tegelijk wilt wegnemen. Mijn inzien ontstaan daardoor meer krachten op de beitels dan nodig is. In plaats van 1 keer veel materiaal weg te nemen zou het geen kwaad kunnen om in meerdere stappen materiaal weg te halen. De bout waarmee je de toolpost vast zet.... heeft een te kleine diameter. Met als gevolg teveel speling. Mocht je de juiste maat wel hebben dan bevorderd dit alleen maar de stevigheid.

Quick tip if you mount your parting blade upside down and part off in reverse the tool will push away instead of plunging ,good for less than rigid lathes (as long as its not a screw on chuck)

G’day RM, precision is optional, we’re from the same school, close enough.
