The Secret Society of Lathe Trolls

If your plan is to cut PVC I've read Jesus say that the VCA should be higher than the usual one we see for lacquers, to compensate for the spring back effect of pvc. Then again I don't have any source to back this apart from a facebook comment. I found on their website that the default rake angle o...

I can't edit the message, by push rod I mean what you called the drive bar in that other thread. I've seen examples where they are perpendicular to the record, and others where they are perpendicular to the torque tube. If anyone has infos about this that would be appreciated ! In my case, they are...

Wow! Great progress - congratulations. The ten months of math and brain smoking have paid off. Now you have a great result.
Greetings from Austria
Thomas

I can send you one, you want a father or mother stamper? WOW! That is wonderful! Thank you very much and of course I will pay all transportation costs. If there are any other costs, please let me know. I will send you my contact details and address by PM. I'll ask you to decide whether it's the fat...

I looked on E-Bay but don't know the seller. But if someone needs such a cover plate for a Presto lathe, then $15 would definitely be worth a try - I think. noch 3 Tage: https://www.ebay.at/itm/226005143791?itmmeta=01HQ1EY9WR384XA3YJYR09QHHG&hash=item349ef4d0ef:g:-7oAAOSwOJtlzpoH&itmprp=enc%3AAQAIAA...

New CH-9 cutting head (part 3) 10/2023 I had to play a bit with the programming, because Mark distracted me with it and I spent days on these things again instead of continuing! Thanks Mark! :lol: (I get distracted so easily :roll: ). But now I have found a little time to continue writing the repor...

Hi Thomas, I'm glad you found this helpful. ... Hi Mark, I've done it with the timers & PWMs! - Thanks for the tip, it's much more elegant to program. I also took the opportunity to reprogram the turntable lighting. Previously I only had blue or red light (LED strips) to indicate the status. (Blue ...

nice design for the head! it goes very small in size. great job! did you change the type of aluminium from last time? I'm glad you like it. The aluminum is (in principle) the same material: EN 5083 (ALU AlMg 4.5Mn). However, with a small defect that was only recognized by the electroplater. The alu...

Neuer Schneidekopf CH-9 (Teil 2) 09/2023 The housing parts of the CH-9 cutting head are ready from anodizing. The wait was worth it. I chose a slightly more elaborate grey anodization and deliberately did not sandblast the parts as I did with the previous models. Because I love the slightly more te...

Hi Thomas, I'm glad you found this helpful.... Hi Mark, thanks for the support. It's helpful again. I have started to study these three pages since the last letter. But I still need some time before I can apply it (at least until the end of the week). https://www.schaerens.ch/iot-arduino-timer/ htt...

Hi Thomas, A better approach to doing the phase control is to use an unused hardware timer setup ... will need to dive into the datasheet for Atmel ATmega328P processor to learn how to program the timers. The Arduino c++ complier allows you to directly reference all of the CPU hardware registers. F...

Heating FP-9 (Part 3) 09/2023 To solve the heating control problem, I changed two things. Firstly, instead of a permanent measurement, I carried out a time-controlled measurement of the surface temperature. And secondly, I developed a controlled lamp heater instead of a "brutal" on/off switch. Firs...

I have a request. I love records but only work on cutting in PetG and have no access to the art of pressing. But I would like a picture for my wall that has an LP stamper (12"/14") in it. So if any of you loyal trolls have a nice LP stamper to spare, I would be grateful if you could send me somethin...

Any tips for marking the exact center of a circle? I'm not a professional (like Flo), but even if you don't hit the centre point 100% accurately, it doesn't really matter, as you're only accurate to 0.2mm at best with the screwed mount. But if you want to be really precise, then clamp the bolt in y...

Heating FP-9 (part2) 09/2023 To improve the temperature measurement not only visually, but also technically, I have installed an additional automation system. Previously, I had to swivel the measuring arm (which was made of plastic) over the turntable by hand (and turn it away again by hand at the ...

This is one of the best threads on this forum by far. I am building a lathe from scratch with way less knwoledge, gear and professionnalism. When I see what you do I tell myself "maybe one day I'll get to this level". So your lathe might not be a VMS80, and it probably never will be, but your passi...

This forum is called the 'Experimenters' & Innovators' forum' not the 'Do Precisely What Has Been Done Before forum'

THX, I see it in the same way

Heating FP-9 09/2023 As I haven't finished all the parts for the cutting head yet, I'm continuing with the assembly of the lathe. To do this, I have (once again) planned an improvement to the plate heater. It's the 100th version (I feel), but this time I have a good feeling. First I assemble the me...

Great work farmersplow, if it's any consolation I've been use PLA printed bearings for my carriages and they're silent enough for me - Igus bearings would be a great step up for me. Thanks for sharing your developments. Thank you and I'm glad you like it. And thank you for your openness. Some would...

Oh for heaven's sake, just go away.

I didn't want to say it so directly
