Stuff you have made today

[MattF]

Not made, but just been playing with a label printer I got a while ago, but have only just unboxed. A test print, which I'm very tempted to stick on the outside of my flat door.

Finished making the motor bracket and securing strut. Next job, make or purchase two pulleys.

I'd think seriously about adding in another pulley reduction. in there, or at least make the pulleys swappable so you can get a 1:3 and 3:1 ratio or whatever you fancy.

 

[Cobbler]

Hope you signed & dated it under the top or like a lady friend did with her bespoke dining table , she had everyone who came to her home sign their name & date on the top then after 12 years had a plate glass top cut for it .

Bit like notches on the bed post

More holes.
Just need the mounting holes for the controller boards, then I'll get the panel shoehorned back in the cabinet, and wiring can begin.

You've got a lathe just use that to make them

Can't beat a bit of panel building

One of mine....

I've already started. One pulley is now made, including the keyway. All that's left is cutting the grooves for a poly vee belt. I need to decide how many ribs. It would be nice if I could find an online reference giving some guidance.

I aim for that level of neatness, but I've never yet achieved it!

 

[Erie Fred]

Dog clamps to go with the sheet lifter beam, the carriage bolt is for alignment, is only 5/16" dia.

Do you need any terminal blocks??

 

[Kram]

Difficult drop zone so I didnt climb this one, but I cut the larger logs. Test of freshly sharpened chain on the grinder yesterday, was cutting well, I made some improvements to grinder recently.

Lovely variable coloured spalting in the middle picture , be good for making lamps table tops , turning on a lathe or pen making etc.etc.

I've not got that far yet. I need to go through my terminal box and see what I've got.

I spent over an hour last night going through RS trying to decide on contactors for the Servo/VFD power control that wouldn't cost too much, and whether I wanted to use 24VDC or 240VAC coils.

Philistine , get an air or ground source heat pump

Perhaps but its rotten and smells of vomit, so I wouldnt want it as a table top.

If you decide to go 24v dc give me a shout, I have quite a few of various sorts left over from a job. (No 24v ac though, I’ll have a check but I don’t think they are ac/dc rated) I’ve got loads of terminals kicking around too too!

Like the place in Bedford that was on the news last night? On drilling down for the heat pump it’s believed the drill released a pocket of natural gas , months later the gas exploded killing at least one person.

The Megadyne catalogue has good, old fashioned design guidance in real words and pictures, rather than 'apps' (I used it for the baby TB2 poly-V drive on my little CNC, but I'm guessing yours will be J section).

I opted for 240AC, as the 24VDC supply I bought is only about 2A, and most (cheaper!) contactors seem to need 2A to pull in.
Even if I went for the PLC compatible contactors, they need ~500mA, and the controller can only handle 250mA, so I'd need to use some form of interface relay anyway, which means there's no real benefit to going 24VDC and it would cost me a bigger 24VDC PSU.

I've opted for 2 4pole contactors, so I can have a power on delay to avoid all the drives/VFDs powering up at once.

Off course, I could have just went for a few big relays, but DIN rail mounted ones capable of switching several KW rated drives don't work out that much cheaper than contactors.
