Twinnie, is there a groove cut in the spindle where a grub (set) screw can drive down in to lock the chuck in reverse?

now there's dedication working on a weekend. when i have an unbalenced blank you can see the headstock moving back and foward (blank was about 1.5 kg), it's acting like it's not tightened down to the bed but i have tightned it quite a bit. i'm yet to check the owners manual so i'll do that but somthing doesn't seem right.

[QUOTE=Twinnie;468430]there is still more headstock flex then i would like. this makes me wonder if the dvr has as much since they claim to have the same bed.

i'm also building a heavy stand this week end to bolt it to, that might change things. i do realy like the lowest speed which is great for drilling out the center of bowls and the like, i use a 4 1/2 inch saw tooth bit and it doesn't even flinch!

Never heard of drilling out the centre of a bowl with a forstner bit, would be a lot quicker with a bowl gouge.

Twinnie mate you are scarying me here. I hope it ok. Two more sleeps and I will be able to tell you for myself. Still am excited about getting it but bit towy now too.

I would say the headstock is not tightened down enough.
The handle that goes into the rear of the casting has a taper on the end which goes into a taper.
If you take the handle out and witha torch have a look into the hole to make sure there is a hole for it to go into and it is not just rubbing up against the side of the pin.
The pin comes down from the headstock through to the base.
If there is no hole in the pin and you can see a rub mark on the side of the pin then you will have to raise the headstock up completely. There is a bolt under the headstock that need to be removed first then lift up the headstock and turn the pin till it aligns with the hole then put the headstock back down again. Make sure you replace the bolt.

When you look in the hole again you will see that the pin is slightly above centre height this is so when you locate the locking handle it pulls the headstock down.

The handle has about an 1" of it machined and there is 2 rings around the machined part, the handle should go into the housing up to at least the second ring if not then you are not locating in the headstock pin.

You should be able to hand tighten the handle up to the second ring then use the knockout bar to tighten a further quarter to half turn.

ah ha! that explains every thing after reading your last post jim i had a look at my lathe and then the owners manual and relised 1: i didn't have the lock pin in and 2: i can't put the lock pin in because there is no thread in the bed casting! there is a hole as detailed on page 11 of the manual but no thread.

so toni don't worry your's will be fine.

Matt

Twinnie, one more sleep and I will tell you definitely. This time tommorrow she be here where I can whisper sweet nothing to her. I am so excited. If the courier to slow, I be chasing it down..LOL I can't wait. I am still excited about getting it but I have printed out all of Jim Comments to make sure I get it right.
bye

Matt it is a strange comment that you can't put the lock pin in because there is no thread in the bed casting.

If it is the same as the DVR, then the thread that the locking pin locks into is deep under the headstock and probably can't be felt with a finger - have a look at the cutout of the diagram in the manual.

Could you explain your situation by answering the following:

1. Can you screw the locking pin into place or does it just spin around without locking?

2. Does the headstock still move under load?


Toni, if you get to read this before you unwrap the lathe, make sure you read the assembly instructions in the manual before attempting to put the headstock onto the lathe bed.

Wait to hear.

She purrs like a kitten and she is a ripper. I am so pleased with her. She is gorgeous.

i can explain, the lock pin doesn't even fit though the second hole in the bed as detailed on page 11 of the manual. it looks like if it was tapped then it would, but the second hole is smooth.

i just checked again and i can just fit my little finger in the hole and when compared with the lock pin... it's as i suspected it just need threading.

the easy solution would be to thread it my self but i'm worryed about the warrenty if i do that.

i have emailed teknatool and the reply i got was from some one called fang hong and said they were a newzealand company and i should send it to the usa to be fixed, this would be an understandable mistake but i started the email with g'day. i'm going to ring them tomorrow and see where that gets me.

jim do you have any trouble with warrenty claims? as far as i'm conserned this is an out of the box failure (like a broken motor would be). i'm a bit worryed now because there is still the matter of a drive belt thats unjoining it's self and i havn't had it a week yet!

have i baught a lemon?

Matt

p.s. i realy didn't expact to see you on here tonight toni i thaught you'd be turning into the wee hours. you like it?
