Re: Parting tool holder

Blade has to be thinner than the insert for clearance. So GTN 3 should be 3MM wide right?

Re: Jet 1236P

Depending on how old it is anything made 2000 up should be a gearhead with D1-4 spindle . Tooling no issue as to tool post -centers etc. They came with follow rest-steady rest,3&4 jaw chucks and faceplate. Normally dual voltage single phase -can be wired 110-220. If by some chance it is a belt drive...

Absolutely, most important thing is how much bed wear does it have.

That lathe has a hardened bed so unless really abused should not be a issue.
OP should jump on it if in good shape,as 12X36 imports are around $4500 + now.

Re: Logan lathe

Location has a LOT of bearing on the price ! Also tooling chucks-toolpost etc. I personally do not care for threaded spindles as I tend to do a fair amount running in reverse,that said millions of lathes were made that way with no problems in use. If it is under power run it up and down across the s...

Re: Drilling Hole In Sandblast Cabinet For Bulkhead Adapter

The step bit starts it's own hole ,then keep drilling to the desired size. You do much hole making in sheet metal you will love them.

Re: Drilling Hole In Sandblast Cabinet For Bulkhead Adapter

Just like a regular bit ! The end has a normal drill grind on it and each step is sharpened . Bits are marked with each size ,what I do is wrap a piece of tape around the bit on the step above the desired.

Re: Drilling Hole In Sandblast Cabinet For Bulkhead Adapter

Get a "step bit" multiple sizes on one bit ,designed for sheet metal work. They make a set of three either 1/16 or 1/8 steps depending on the bit size. In US Harbor freight has them cheap and seem to work well for home shop use, have had a set for years.

Re: Parting tool holder

Make a holder! I have 4-5 of those insert holders ,one of which resides in a shop made holder block which is 1/2 " The rest are 3/4 which fits my Multi-fix style post,they can take up to 22MM = a bit over 3/4" Bad thing is I have at least 3 different styles/widths of inserts !

Re: Mill and Lathe Recommendations for High School Machine Shop

Most all of the imports will suffer from lack of parts availability sooner rather than later ,used American has the same issue only now. The next question is how many of each machine are you planning to buy? I can not say it firmally enough stay away from 3in 1 machines and drill/mills. Saw in a Gri...
