Re: Sliding Table Saw Felder K700 S - Minnesota
开云体育Cliff, ? I always clean an item if I am selling or giving away. I have wondered why some don’t bother. The only thing I can think of is that the seller may consider it is best to show as is to best access how it was used. Or they may be lazy, LOL. ? Imran ?

Re: Sliding Table Saw Felder K700 S - Minnesota
开云体育Brian, ? I kindof replied with similar thought. Also, if it is hard to find a machine locally then one may consider a less than ideal machine to save $1K in shipping. Crating is on top of that. Lots of things to consider. To each his own. ? Imran ? From: [email protected] On Behalf Of Brian Turner

Re: Sliding Table Saw Felder K700 S - Minnesota
I'd guess $5-6k tops. It looks pretty best up, and given the units of plywood sitting near it I would guess it was used hard.

Re: Sliding Table Saw Felder K700 S - Minnesota
开云体育Hi Bill, ? I just shared without commentary. I agree that it is a well used machine and likely in more than hobby use. It is however, connected to power and someone interested could go and see it in work to access the condition. Sometimes a well-used machine can still be in good shape if well maintained. I also agree price is high. Maybe in $4-5K be reasonable if in perfect working order. ? For some people with limited budget it is good to find a used machine at lower cost. I was able to get K975 for $4.5K. It looked great in pic but was well used when I saw it in person. However, I cleaned every accessible surface including polishing the plastic side cover. I had to replace over a dozen small parts and make some repairs and ended up with a machine at 50% to 75% of typical price. Attached pic is when I was calibrating slider. ? Imran ?

Re: Broken Tap
Most taps have a countersink on the end so that you can use a DP for alignment when hand tapping:
Use thread cutting fluid, not 3-in-1 oil.? It makes a big difference. Spiral taps are more expensive, but require less torque.? ? ? Chamfering the hole will ease starting. Get combo drill/taps: Then you can do it in one step on your drill press.? And if you do drill holes separately, still use the drill/tap in your hand tapper because drill part makes the tap self-aligning and you don't need to fuss with guides or eyeballing a square (obviously only applies to thru holes) ? ? |

开云体育oh? and if ya really? want to just drill a hole and tap it? Get a
free machining steel.? I like? any of the Leadloy? free machining
steels Ya can braise 'em but ya? can not weld? them and they cut
like Buttah.? When tapped it's almost like they are self lubricating.?? you can
use 12L14.? The stuff is almost like machining Acetal plastic On 12/13/20 7:55 PM, imranindiana via

Re: Broken Tap that's not a manufacturing defect that is a purchasing mistake
Cliff Rohrabacher, Esq.
开云体育You bought the wrong tap.? Cheap taps are? worthless, as you
discovered. Taps? worth buying : Balax for thread forming.? OSG and Emuge for cutting. I? don't know of another company making? taps that are worth a damn.?? For hand tapping? Use either thread forming taps or Two Flute Gun Taps. For bl;inf holes use Spiral taps? they are usually three flutes There is? absolutely? no circumstance in which I would bother
with a four flute tap. They are weak as hell? - - which you just
found out.? Use a high sulfur? cutting oil? or a specialty? tapping fluid? like TapFree there are many good tapping fluids? In malleable metals like Steel and Aluminum I prefer to form the threads? instead of cutting.? If you are jobber you need to check the print and see if they are acceptable. In high hardened steel? I prefer to send it out to an EDM shop
but I can tap? pre hard 4140 and 4150? if the hardness is? 48 RC?
and not more. 1018 is about the same as A36.? it is a Weee skosh more? machinable? but not worth the money? unless you are running lots of it and need the? better finish.? It takes more skill to get a great finish on A-36.
Cold Rolled is? OK? if you plan on doing little more? than
drilling and tapping? but if you plan on machining the mill
surfaces then? stay away from the stuff.?? The stresses in the
surfaces from the? rolling mil will cause the metal to form banana
shapes as you remove stock from one side or the other and you can
be chasing your tail trying to get it to lie flat? all day. On 12/13/20 7:55 PM, imranindiana via

Re: Broken Tap
Sorry to go off topic but I am unfamiliar with the Survival Guide. Is this only for a Felder slider or would it be worthwhile for all? Thanks.
