    Portaband blades and technique?

    Who? No. The form factor of the tool driving the blade doesn't change the fact that there's not enough gullet area to absorb the swarf in a high-pitch blade.

    Will aloris tool holders fit on a dorian tool post?

    I can confirm CXA are cross-compatible as well.

    Continuation of apparently deleted shop ceiling height thread

    Thanks for the feedback I got on the other thread. To fill in a few more details, the entire shop building is 60x80', with the machine shop being one of the two 20x60' "lean-to's" straddling a central 40x60' fab area, which is the larger of our work. The fab area will have taller ceilings, more...

    Thread about shop height dissappeared?

    Hey all, I was coming back to update some details on a thread I started a few weeks ago about the optimal shop ceiling height. I can't find the thread using the forum search, nor is it in my "your content" section like it would be if the mods had moved it to a different forum. Anybody know where...

    Adhesive to put on non-psa sanding discs bought by mistake

    Thank you all for the input. It does seem like some kind of contact cement solution would be a good one, and even better if it's meant for this application. I knew some of the old timers would have a good solution, since PSA hasn't been around forever. :) I'll try the local rubber cement first...

    Adhesive to put on non-psa sanding discs bought by mistake

    Hey all, got an unreturnable batch of 15" discs that I thought were PSA but aren't. Any adhesive recommendations? Glues don't hold well here in my tropical weather. Grizzly PSA discs would fall off after a month of so (never being overheated) because of the humidity in west Africa. 3m and Norton...

    HDPE air line kits.....any users??

    What was that pipe rated for, do you know? When I didn't have time to research, I threw a 25mm 10kg PE line into the trench to carry air to my paint booth in another building, figuring that I could step the air pressure down because there would be plenty of volume even if I could only safely...

    3d print filament stand up to oil exposure, for collet racks?

    Looks awesome! That's just what I had in mind, a way to organize them in a Lista drawer that doesn't involve wood to suck rust-preventative oil away from the metal. I had thought to have the top thicker and match the taper to hold them securely, but do you find they stay put just fine like that...

    3d print filament stand up to oil exposure, for collet racks?

    Yeah, I made sheet metal racks similar for 40 taper toolholders, and that works great where there's some weight!

    Mk 1.5 Colchester 15x48 headstock oil seal

    Thanks again. A companion problem that it feels like I should tackle together with this is that since I've owned the lathe the oil level sight glass has been too smudgy to read. If I drain the headstock anyway, I assume that pressure fit in such that I could push/pull it and clean it good with a...

    3d print filament stand up to oil exposure, for collet racks?

    My shop climate means that I have to maintain frequent light machine oil applications to keep bare metal for rusting. I'd like to 3d print racks for my TG100 and ER16 collets (because metal in contact with wood rusts here once the wood absorbs the oil away from the tooling). Anyone know if...

    Mk 1.5 Colchester 15x48 headstock oil seal

    Thanks for all of the feedback. I'll pull the lid off of the headstock and see if anything is apparent. I like the idea of some compressed air through internal oil passages, that's worth exploring.

    Mk 1.5 Colchester 15x48 headstock oil seal

    My headstock won't hold oil, and whenever I fill it up, the next time I run the spindle it slings a bit of oil radially. I now remember that at one point there were some thin bits coming out of the spindle nose, kind of like you'd imagine pieces of a plastic grocery bag. I hadn't connected it...

    OT: Love or hate floor drains?

    Thank you all! Yes, no EPA here, not that I'd want to be putting harmful stuff in the ground by my house and community well anyway. I agree that I don't want any slab slope, the drains would just be to have a place to squeegee the water to that's closer than the front door. There will already...

    OT: Love or hate floor drains?

    I'm building a new shop, wondering if anyone has strong opinions about having or not having floor drains. My shop will be 60'x80' - a central 40x60 fab area with two wings, 20x60 machining, and 20x60 CNC plasma, sheet metal equipment, storage room, and office. I'm considering a single drain in...

    Laser level on domestic flights?

    I flew internationally with a Hilti leveling laser (the big surveying ones) in its case in my checked bag with no trouble.

    Problem mixing galvanized and stainless components?

    Thanks for the responses. Not to add complication to the discussion, but in this case I'm using stainless precisely because of salt-water proximity. The brackets and fasteners are to secure a timber-frame truss over the front porch of this little guest bungalow (red), which is right by a finger...

    Problem mixing galvanized and stainless components?

    Thanks, that's what I wanted to know. Obviously aesthetically I'll eventually use stainless fasteners to go with the stainless brackets, but wanted to know if the galv fasteners until I can arrange the stainless would attack the brackets in the meantime.

    Problem mixing galvanized and stainless components?

    I'm curious, does anyone know if there's some kind of corrosion problem mixing stainless and galvanized? In my specific application I'm making tie plates to mount timber frame trusses to masonry columns. What I have in stock for making the brackets is stainless plate, and have some hot dipped...
