Taig lathe tool holder

Because the shaft is made from toughened steel, set screws do not deform or indent its surface, so that the tool holder can always smoothly slide up and down along it even after repeated tightening. This hole is tapped from the top of the tool holder to a depth of 12 mm. This pin is put aside for the time being and will be inserted into the lower part of the hole when the item is assembled and mounted. I slid the tool holder onto the shaft and temporarily lock it in place with the set screws on its side.

I secured a suitable tool bit in the tool slot with the two cap screws as originally intended. I inserted the long cap screw locking screw into the shaft from the top.

I then placed the shaft onto the base and loosely screwed the square locking nut onto the end of this screw. I finally slid the new assembled toolpost into one of the T-slots of the cross slide and locked it at a desired position. To adjust for centre height the tool holder body is unlocked from the shaft by loosening the two set screws. Turning the adjustment screw against the pin further down the hole changes the height, clockwise to raise and counter-clockwise to lower.

When the desired height is reached, the set screws are tightened. The back toolpost sold by Taig has the lower edge of the tool slot milled at lathe centre height, so I use it as a handy and accurate guide for adjustment. The cutting angle of the tool bit can be changed easily without affecting its preset height. Loosening the long locking screw in the shaft allows the shaft and attached tool holder to rotate in its base socket to the angle desired.

Tightening the locking screw again will secure it in place. I made this adjustable toolpost in just a day without using any sophisticated equipment. I used the factory supplied toolpost and modified it. I used recycled materials whenever I could, costing me practically nothing.

Since this is made for functionality and not for appearance, I have little concern for cosmetic imperfection and do not bother to polish surfaces to an appealing finish. Putting the modified toolpost onto the cross slide, I find it to be just as rigid as the unmodified one, very easy to change tool bits, adjust centre height without shimming, or adjust tool angle.

It also allows me to easily swap in a set of 8 mm bits which I have bought earlier at a garage sale. I find this project to be the perfect first DIY job on my new lathe! Since writing this Instructable I have made further improvements. These are nice to implement but not essential. I made a new lock-screw from a 5 mm mild steel rod.

The square nut at the bottom end is permanently tightened onto the thread. A 12 mm round handle nut screws onto its top. This rod serves as a handle to tighten the lock-screw.

All the rods are salvaged from a laser printer from a neighbour's garbage bin. I also replaced the height adjustment cap screw with a length of thread attached to a brass knurl nut which are held together with locktite. I put a small spring under this knurled screw to prevent it from rattling loose under vibration.

With these modifications, I no longer need to get a hex key to reposition the toolpost or change the tool bit angle. I still need to loosen the two set screws with a hex key, and then twist the knurl nut by hand to adjust for height, but this infrequent adjustment is only neccessary if I change the tool.

I have not included these improvements as part of this Instructable since they are quite easy to implement and there are no critical steps to follow. The screwed on index at the bottom of the base has been removed and replaced with an angle clip screwed onto the same position on the side. The clip retains the base connected to the tool post when dismounted from the cross slide, keeping the assembly as one integral tool. Reply 5 years ago. I've been turning since the 80s an not heard of this brand Taig is a small and affordable lathe intended for delicate and accurate work.

It is ideal for a tinkerer like me. If your lathe is not Taig, you may need to fabricate the tool holder. I would suggest steel but alloy aluminium will do. But then it can be made a little bigger and you can avoid having to drill an off-centre hole for the shaft. I've got a 7" x 16" [mm x mm] lathe and make my tool holders from aluminum, it works good enough for me to turn more aluminum as well. Introduction: Adjustable Toolpost for Taig Lathe. I mount the work piece on the four jaw chuck and offset the rotational centre to 12 x 12 mm from one corner.

I then drill the hole through. I install the milling attachment onto the cross slide. This is locked with two long screws accessible at the back. Both screws are recessed into the heavy aluminium body, and one is particularly difficult to engage owing to its depth.

A short length of 12 mm cylinder, drilled through with a 5 mm hole, inserted into the recess helps the hex key locate and engage the screw head. The attachment is normally attached with the T-slots parallel to the cross slide, i. A sliding plate secured with cap screws at the back helps keep this in alignment. This is very convenient for this project.

I then attach the milling vise across the attachment T-slots, using an engineer's square to true it up. Two faces of the work piece have to be milled. They are those furthest away from the mounting hole drilled earlier.

I then secure the work piece in the milling vise, long side across. Putting a 12 mm end mill into the three jaw chuck I proceed to mill the entire face down to the edge of one side. The work piece is then rotated for the other required side to be milled in the same way.

The through hole drilled earlier is now at the centre of the bottom face. The next stage is to mill the slot where the tool bit is to be mounted. This slot is cut into the sloping corner of the work piece from top to bottom.

When the tool bit is mounted with its nose up, its orientation will be dictated by the geometry of the block. I use a 6 mm square tool bit. It will be secured with two button head screws so it will be milled just under 6 mm deep each side.

A bigger or smaller bit may be used; you just have to cut the slot to size accordingly. I prefer a bigger yet manageable bit with a larger frictional area against the tool holder body.

The two bottom cap screws mounting the milling vise to the milling attachment are removed. I mount the work piece so that the sloping corner edge runs horizontal and at right angles to the lathe bed. The work piece is now positioned correctly for the tool bit slot to be milled. Using a 6 mm end mill, I carefully mill a square notch into the corner just under 6 mm deep into both sloping faces.

Part of the tool slot towards the top has to be milled away to provide clearing room for chip removal. I return the milling vise to horizontal, re-attaching the two bottom cap screws and nuts.

The main attachment is also returned to its normal position perpendicular to the lathe bed, I then secure the work piece in the vise, rotating it diagonally so that the tool slot faces outward. You can hear it run in the video. It hums like brand new. Not numbered: the Very neat. I think there's a drill chuck or two in there- little miscellaneous tools and widgets you need to operate the lathe.
