Hi,

Attached is a 35 mm diameter handle I’m suppose to manufacture. As in the image I need to insert a 14 mm straight hole 130mm/140mm in both the pieces.

I would like to hear suggestions on how to do the boring successfully. It has to be dead straight and the solution should be a fast process.

Thanks in advance.

Since you’ll want to turn the handles on the lathe, do the boring on the lathe as well with the drill bit held in the tailstock and the wood turning. This will ensure that the resulting hole is centered. You’ll want some sort of steady rest a the end of the wood being bored to keep it running true as the tail stock won’t be holding it. This can be a skateboard wheel affair or as simple as a board with an appropriate hole drilled in it and bolted to the lathe bed for 1 time use. If you’re not familiar with steady rests there are good examples here.

Thank you for sharing your thoughts. I’m planning to utilize a CNC lathe and I was told the the tailstock can’t be replaced.

My guess is I’ll be needing a manual lathe as well for boring operation.

Any other suggestions?

The tailstock wouldn’t need to be replaced. There is typically a morse taper in the tailstock and there is usually a jacob’s chuck with the mating morse taper at the lathe. That holds the drill bit. If you youtube how to make lathe tool handles I think you’ll see examples of how to do what you are wanting. This guy does it without any kind of steady rest at all.

Sorry, I had one more link I wanted to throw in here. I read your other forum thread and realize now you’re talking about making a lot of these. In that case the expense of an off the shelf steady rest is probably not an issue. Oneway makes a nice example, with clamp blocks to fit about any lathe, but there are lots of others.

Hi,

Thanks for the info. This may be a stupid question. Since I have not seen a CNC lathe directly in operation I tend to ask this.

Can we also use a drill bit in a CNC lathe tailstock?

Regards

Have your say...
