Re: HF Lathes
For the 7x lathes the cheapest is the Homier ($299) but it comes with no tooling. Next is the Cummins for $399 with a good accessory package The Harbor freight is actually 2" shorter than the others

Re: Way Wear, Hard Gibs
G'day Marty,John, Gianni et al. To extrapolate what Marty is saying suggests a lathe should never wear out. Unfortunately that is not the case. The contaminants have to be factored into the

Re: Drilling HSS 10% cobalt blank

Re: Carbide Insert Nomenclature?
Carbide Depot's site has a pretty good section on decoding the insert nomenclature. They frequently have some good deals on "surplus" tooling. Not affiliated, just a satisfied customer.

Re: Way Wear, Hard Gibs
Hi Marty, Yep, you may well be correct - it may be a non-issue. Then again, without a pretty good reason, I personally wouldn't do it just to find out. There shouldn't be excessive forces. After all,

Re: Harbor freight 8x12 lathe (cheap digital calipers)
Hi John, You raise a good point - I read his feedback comments. 800WATT is sometimes slow on shipment and most now expect rapid delivery unless otherwise notified. My suspicion is that he sells items
