Stuff you have made today

[James1979]

Not strictly 'today', nor is it finished yet, but as I'd gone to the trouble of making a collet adapter set for my Boxford VSL, it seemed like a good idea to acquire some collets. Then I needed somewhere to put them, and as the lathe's cabinet door already had 4 holes drilled in it, that looked like a good place to start.
Slotted uprights and shelf brackets (in brown to match the lathe! ) were found on Ebay and a shelf designed in CAD to suit them, then 3D printed.

This is the result, accommodating the drawtube and handwheel, plus collet closer and the spindle 3MT reducer as well as a few collets:

The second shelf (note lower pair of brackets) will have more slots for collets, plus tailstock drill chuck and maybe live centre. I was going to make the shelves from 3mm alloy plate but a poor stiffening fold on the first attempt caused a rethink. For the moment it takes the weight of the drawtube and provides a home for the chuck locking key:

The odd-looking alloy blocks at the ends of the shelf uprights are there because whoever drilled the door holes failed to get any two of them square to each other or any edge of the door, so the blocks are drilled off-centre to allow the uprights to be parallel!

That 3Dprinting is stronger than I have it credit for.
Looks nice

I made a prototype climbing device and abseild from it.

There are people I know in the tree world who should never find that out!! The sort of people that weld up their own maillons and lowering devices....

I can imagine the carnage if they started 3D printing!!

I do not put you in that category

Wow, I must admit you wouldn't have (survived) with anything I printed. I gave my printer to my SIL because I couldn't get it to adhere to the bed let alone anything else!!!

Hope not, though i have built rigging winches, fortunately i built a load tester and pull tested it before i used it.


I've had my components laser cut for the climbing device i just need to machine the final parts.

I would post some pictures but i only have 3 competing devices globally.

I leave the technology to you younger folk and abseiling for that matter

...the dovetail is a different width...

Glue some shim stock (feeler gauge) onto the narrower ones to make everything the same.

Easier to remove some material from the wider ones now I have a cutter

I have found my set are quite 'tough' hence thinking I may need to harden the ones I have made.

Some of the tool holders I made years ago were for a toolpost I had on the Student lathe, it was slightly bigger than the one I have on the Triumph. When I sold the Student I kept some of the holders but they were slack on the Triumph so I fixed a bit of shim stainless to the wedge side with an m3 screw underneath, works great and allows me to use them without having to insert a shim every time.

I'm thinking it might also be stronger if you can successfully embed rods & plates into the printing out exercise , but that might require quite a bit more thought & making notes of your ideas during the brain storm sessions as to how to do it .

I wondered that. Maybe you would print to a point, drop the reinforcement in then carry on? Allowing for it in your design file?

dunno. It’s an interesting subject, just can’t really justify one.

No need to, you can get fibre laced filament. Heat is the biggest killer

Ah ... That's cheating using a posh machine and cutting fluids .. I have the antique Sphere cira 1943 so don't have a wet set up ( not likely to either ) I usually cut everything dry or or use a spot of compressor oil on an artist paint brush or use WD40 through the tube attachment if I need lube. Might try and do that and see if I can get a better finish instead , it never occurred for me to use lubrication ..

You need to keep nylon cool and I would think that more important than actual lubrication but...
I use flood all the time on the Triumph as well and always when turning nylon.

I did not have any problems with the Delrin that I made handles from if I did not do many consecutive cuts. Perhaps take a couple of cuts, do something else for a couple of minutes then have another go, at home we are not up against targets so no hurry.
It did not occur to me when I was doing it but compressed air would take away some of the heat, if I remember, I will try it next time.

Delrin/Acetal is a totally different animal, machines beautifully and holds dimension well. You can cut dry or with coolant and can take as much DOC as your insert edge length will allow. Love to machine it, unlike nylon

Customer needed this lead weight cut in half. So I set it up on and angleplate in the bandsaw but I was having no joy. Blade kept jamming. Lead was so soft it was just deforming under the clamping forces. So I draw around it, plasma cut a template, welded and bashed some 5mm around the outline and we had a mould. Chiselled the rest of the lead into two halves and now we have such.

starting weight 4kg. Lost 315g to the saw and slag

Following on from yesterday’s acquisition on that thread. I have made dinner:

I have to admit that the only nylon I have turned was some replacement rollers for the shower screen which were small but quite detailed so all the cuts were light. The delrin I did manage to melt but as it was tapered between centres it was probably spinning a bit slower than ideal.
I still think cooling it with compressed air is worth a try next time I go near the stuff.

Yes you can, with some G-code tweaking.
M601/602 will pause and resume.
Probably you also want to move the head away so G60/61, store and restore position, will be helpful.

If you print with support you need support blocker in the void or load 3D of the insert and set it not to print.
