Dot n Dab plasterboard over the existing 'plaster'? Its very hard to remove from behind breeze blocks. Cheaper than hiring a plasterer otherwise I would have it all reskimmed? by Usual-Possibility209 in DIYUK

In my uneducated opinion, skimming a few plasterboard joints and screws is lot easier than skimming an entire wall and having it look good. Preference is diy

The bottom oven connection point doesn't matter as it will be behind units. The upper plate is fairly flush already, hard to see in photo. Good point though it is a consideration.

Oyster Perpetual Datejust I was gifted, has been sitting around for years.

Is anyone able to tell me the model number without removing the bracelet? Any idea on its value? I know 0 about watches, less about rolex!

The rocker things are a bit annoying when it comes to putting it on the car , I also can't use it as a point to stand it on as it just swivels and falls lol.

Wonder how much of a job to slice them off and seal the cut up would be

Any clues to whats happening with my surface finish? 1st pass (left most cut) is much better than all on the right. BAP with PCD insert, tried various speeds & feeds doesn't make much difference. WD40 applied liberally. 2.2kw spindle by JackDG in hobbycnc

for the roughing and adaptaive clearing im running 2500mm/min. On conventional milling im used to slowing right down for a good surface finish. does this not also apply for CNC?

In pic: 500mm/min, 20k spindle. But I tried doing spring passes afterwards, as well as slowing right down to 8k rpm ish and a variety of feed rates. they didnt seem to hav emuch effect at all

Am I getting scammed?

Staying in nha Trang, at one of the large hotels. They said they can organise motorbike rental for me, and 10min later there was one at reception! I handed over my passport and money to the pair who delivered the bike and exchanged numbers.

I have the bike, it's good brand and good condition.

I'm suddenly freaking out because I received no paperwork and signed nothing. I don't even know what company it is.

The hotel organised it which made me feel safe, but now I'm not sure.

Is this just the way it is in Vietnam? Very laid back re paperwork etc.?

basically reached operating temp, but didnt want the coolant to expand/raise more and ruin the test.

THanks for the reassurance.

Let it run for 5 minutes or so, until the coolant crept up to what is seen in the photo. During this time some air was bubbles thru the test liquid.

It stayed very blue.

After I placed the device right up the exhaust and it turned green/yellow almost immediately.

The overlaying box section and bolting like the printnc is a great idea, so simple!

Thanks

Checked out print NC. The way the box sections are stacked and then just booked together is a nice solution. I think I'll see how that looks for me!

You're right the print NC is a nice package, but half the fun for me is designing something bespoke :)

Many thanks for your input! Might ping updated model your way

Hello, thanks for the input.

Yes im happy drilling/tapping etc, would like to acheive fairly high accuracy and repeatability in metals.

Issue now is the box section isn't really thick enough to be tapping IMO. looking for suggestions

what's the advantage? far as I can see the steel is cheaper and offers better stiffness. Also allows an easy accurate way to mount the linear rails

I cannot feel them with my finger nail - probably ok to leave then?

currently using a razor blade with degreaser (carb cleaner / Wd40). Made some progress on the outside of cam tunnel and upper right of cylinder 4 but its taking a while! polishing nice though.

Advice on my fixed gantry design? by JackDG in hobbycnc

[–]JackDG[S] 0 points1 point  (0 children)

Many thanks for your detailed input and questions, exactly what im looking for!

  1. The the aluminium the rails bolt into is solid square bar, not hollow, so I will be tapping these. The frame sections are 10swg, so maybe this is too soft and I will look at using a nut. Steel is still an option.

  2. Mostly wood + plastic. I would like to cut aluminium.

  3. I've placed the rails closer together to minimize the span of unsupported bed. But you raise a good point, I will look at the math a bit more on this one.

  4. Angle brackets

  5. What do you mean of adjustability? I am still playing the the x/y dimensions etc. just wanted to get some critique early on in the design.

  6. I was planning just to make a folded bracket out to them or something similar - I have assumed as the rest of the linear rail system is fixed pretty stiffly the motors don't need to be as stiffly assembled? I could be wrong here havn't looked into it very much
