Re: Buying & Using a Knurler
Usually, you sort of match the knurl to the work diameter; little things with coarse knurling look odd. On the 7xX, the machine isn't rigid enough to be happy with a fixed knurling tool; the scissor

Re: Best Plastic to use
Hi, Just a suggestion. For making plastic handles on shafts I turn a few grooves (for axial keying), grind a couple of flats (for rotational keying) and then cast the handle with fibre glassing resin

Re: Max workpiece diameter for fixed steady?
Hi Chris, I assume we're talking a Sieg 7x here? I just measured my Sieg steadies (I have fixed and moving) at 1-1/2". I think you'll need to fabricate your own. You'll need a pretty stout structure.

Re: 1st Timer Accessories-Which 4-Jaw chuck?
Hi Rance, I'm running a 7x12 so can't give specific models. However, I could not conceive of having a lathe without both 3-jaw (scroll) and a 4-jaw (independent) chucks. My machine came standard with

Re: 1st Timer Accessories-Tool Bits (HSS vs Carbide)
Hi Rance, I bought both HSS and a set of carbide tools. I work mainly with steel (and stainless). Later I read that carbide is a bit of a pain on these small lathes as it's prone to digging in,

Re: Buying & Using a Knurler
Hi Rance, Gerry, The other snippet I picked up somewhere in my reading is that you shouldn't be too timid when starting the knurl. As the initial imprints come around again the knurl teeth need to

Re: Tailstock chuck - Groz vs. LFA
Trevor, Now I'm very glad you posted that link. I went out to Busy Bee this afternoon, and they had a chuck that looked just like the one you pictured except it had a JT-6 taper for $17. I just

Re: Max workpiece diameter for fixed steady?
Hi Chris, I have never tried this but perhaps you could make a loose plug attached to a spindle. Insert the spindle into the tailstoch chuck. Lubricate the plug with silicone or washing up liquid (

Engineman has a nice steadyrest that looks like it could be built to handle quite large diameters, see(near the bottom of the page): http://users.eastlink.ca/~jbentley/workshop.html John

OT: Re: 1st microwave to tear apart
THEORETICALLY if the microwave hasn't been used for a while, the capacitor MIGHT not have a charge on it as many units have a bleeder resistor across them. BUT, capacitors will charge up from static

Re: Max workpiece diameter for fixed steady?
It is surprisingly difficult to get any info on the capacity of steadies but according to littlemachineshop.com the one for the min-lathe is only good for 1" so not a lot of good for you. I honestly

Re: 1st Timer Accessories-Which 4-Jaw chuck?
The standard minilathe chuck is an 80mm (just over 3") three jaw and I suspect that your 8x14 will come equipped with a 3 jaw of similar or slightly bigger size as standard, maybe a 4". Some of the 8

Hi, Based on an article in Model Engineers Workshop I created this spread sheet which figures out the correct OD of what you want to knurl so that the knurl works out.

Re: 1st Timer Accessories-Tool Bits (HSS vs Carbide)
I'm not clear on what exactly you're comparing with HSS and Carbide tools. A say 3/8" HSS blank costs about $2.00 and can be finished on both sides, effectively making it two tools. A cheapy brazed
