The best Cutting Tool Coolants: Reddit reviews

From 3.5 billion Reddit comments

Yeah I bought the air pump as the one above and we are using this zip tied to the laser head to direct the flow: https://smile.amazon.com/gp/product/B006R9O3HE/ref=ppx_yo_dt_b_asin_title_o07_s01?ie=UTF8&psc=1

I’ve got a DIY solution I’ve been super happy with: get half a dozen one-foot lengths of lock line, mount them in a hexagonal pattern on a rectangular piece of 1x12 pine (eg drill holes + epoxy) and top with alligator clips. Gives you an amazingly adaptable holder for all sorts of things. I also have a Panavise, the ubiquitous helping-hands, etc but have never found anything quite as useful/usable as the DIY lock line solution

Edit: I did something like this without the milling etc

While I usually encourage 3d printing all the things, Locline is fairly cheap and works very well.

I just picked up a little starter kit on amazon for like $8, this is probably what you want:

You are right. I second the discussions about speed in terms of surface feet per minute (sfm). I always use RapidTap cutting oil too. Just a few drops makes a world of difference on drills (and taps obviously) and the bottle seems to last forever.

I have the same issue with that same mount. I ended up using a previously made fan duct from this e3d mount plus a lot of trimming with a rotary tool to remove enough material to make everything work. I printed the Klemco duct but it was way too wide and kept hitting the v-slot wheel. Took a bit of trial and error but I was able to create enough space for the limit switch to close but the duct still rubs on the v-slot wheel ever so slightly. I originally tried moving the limit switch but my ABL setup would overshoot the bed and I really didn't want to modify my firmware to compensate.

Alternatively, I have a prototype 5015 blower to loc-line adapter that mounts to the bl-touch bracket for print cooling in the works. For now my jury rigged and hacked up blower mount does the trick.

This is gold! Trust me. I bought brand new Kleins and was generous on the oil worked it in a bit by opening and closing the lineman’s couple days of use and they’re broken in nice and smooth

A pic of the joints might help us help you. I have printed a lot of cable-chain and coolant hose with varying degrees of stiction. It is all in the design, I made a modified version of those.

You could also do a search for "stiction fluids" for your current design.

I use the 1/2” version and that works very well but if you have something heavier then you could go even thicker. Loc-Line Coolant Hose Component, Acetal Copolymer, Segment, 1/2" Hose ID, 5-1/2" Length (Pack of 2) https://www.amazon.com/dp/B006R9OGKS/ref=cm_sw_r_cp_api_i_L.twFbYD6RQ87

Buy some loc-line for the pump.

I like it for mashing then switch back to the silicone for chilling.

Thanks for the advice. I will use the blade that came with the saw as training wheels and get a feel for things. I did order a gallon of TRIM C270CGbd coolant just now, one of the things that is attractive about it is that it has corrosion-inhibiting properties, e.g. it leaves a washable film on the part.

I think you might be better off with something like Loc-Line I just picked some up for a third-hand type device. Here's an example of what you can do with it.
