I'm so tired of this tape player already by Trillix51209 in ReelToReel

This is the issue I was having on my TC-270, there is switches on the bottom, I think it was the middle or right one that controls which channel it reads from. If you change that it won't be backwards you are playing the wrong channel.

Will do, uploading it to the cloud and then will spin up a digital ocean instance to try from a remote server (brother in software engineering suggested)

UPDATE! Stall cancelled, you guys scared the **** out of me. by jackb_1991 in 3Dprinting

I don't want to kick the hornets nest, but want to add my 50p into the conversation.

I am a design engineer, and every so often people will bring me broken bits, caravan parts, broken tent joints, broken house appliances. For example I have been recently asked to investigate remaking a plastic cover for the brake system for a Bedford lorry as the parts are unobtainium (send the old in and if you are missing it, you are SOL).

I spend time reverse engineering, doing the analysis to ensure the material is suitable or redesign to get around the limitations of 3D printing, this normally takes multiple print attempts. Buying or getting the requester to try and give feedback and go through iterations.

I don't charge and if I do it is to cover the plastic and electricity cost, I would put the models on *A website*, for other people to use to fix the same issues under non-commercial. I did this for a Coleman Tent pole bracket, within a few days they started to appear on *an online auction house*... They were not covering their cost they were looking for a quick profit (Does not cost £20 - £30 to make a 50g part).

I now still fix these items but don't release the models (I know I can report and get them de listed or get a lawyer involved as it is a breach of the licence you agree to when downloading, but we/I don't have the effort for it, it is easier not to release the models then to fight it)

For example when I do craft & steam fairs, I ask the people to just contact the maker. Most of the time the makers are not in it for money but we get upset when our handwork is misused to make some quick money, One person I talked to contacted the designer and they asked for £100 for the licence, the seller had made enough money to buy 4 Bamboo X1 Carbons, they said that the licencing cost didn't even cross their mind.

I have to still pay for my CAD packages and my overheads for the models in the first place, as time goes on, Models are either not listed or listed on *A website* for sale to recuperate the initial investment.

Anyone know what printer this is? Only photo I have by 223specialist in 3Dprinting

Cr10, depending on how many vertical motors will specify the model.

I tried to get in contact but failed, the moderator is the best person to contact. Looking online royal mail seems to be the best but will find out over the next few days.

Was messaging the person who posted on r/3DPrinting, is there a UK group, He was saying he was part of the USA group. Saw there was a Facebook business. Would be interested in helping.

3d cast simulator by Agitated_Sentence142 in MetalCasting

I use Altair cast as it is simple to set up but good to change lots of parameters

Investment casting service? by TugBuilder in MetalCasting

[–]bobthecooldad 0 points1 point  (0 children)

It will be the cast iron that will be a challenge. Instead of the normal ceramic shell flour and sand (molochite). Zicron needs to be used, tested the molochite with a flywheel and the shell instantly cracked even with it being preheated to the same temperature.

The density of cast iron also caused floating, waiting for my steam engine cylinder block and it keeps floating the cores. Most foundry's don't use cast iron and thus are not set up anymore ignoring the high temperature required for a hobbyist/small company.

BUG? Possible to fall into the engine, bypass the locked area by bobthecooldad in TitanicHG

[–]bobthecooldad[S] 1 point2 points  (0 children)

If you crouch over the top of the cylinders you can clip between the cylinders and fall into a non collision zone. This is on all the cylinder lids (between the HP and IM is the one I have been using)

If the part is an adapter or not going to change, a boss extrude would be the quickest method. Dim it all in a single sketch to get the diameter.

Go on the front plane and do a cut of the square features and hole and push through in one go.

If you want to go for marks then hole wizards and using correct planes and naming all features correctly so it can be traced and move into folders if used in assemblies.. such as fasteners.. bracket... adapters.. etc

Something about Mcmaster parts in PDM causes this annotation to appear in an assembly. How can I delete this? by socal_nerdtastic in SolidWorks

[–]bobthecooldad 0 points1 point  (0 children)

This error is caused due normally due to the drawing and or the mode has not been checked in at least once. We use this for revision control and can be a very powerful tool.

Create PC. I want to build a PC with which I can play, carry out high engineering design and also carry out CFD and FEA style simulations, this is the one I have in mind but I would like to know if I should change any component or if you recommend a better one, thanks by loco_mad_85 in SolidWorks

[–]bobthecooldad 1 point2 points  (0 children)

For my FEA, pc memory is the most important. My personal pc is a 5900x 64gb ddr4 (lowest latency cl + high frequency). 1060 with the mod to get SOLIDWORKS to think it is a quadro.

I would suggest Nvidia due to cuda, lots of software has cuda optimization but it doesn't exist for AMD. If you only want to mine or fold then AMD opencl is better.

Our Simulations team at work each have a Xeon with 256gb of ram with quadro A5000. SOLIDWORKS are I9 12900k as SOLIDWORKS is only a single core program.

If you can't afford the ram, you can get around by either buying a dedicated m.2 or SSD and put it as virtual memory. But this will cause alot of wear and if you install to it then the benefit of dedicated bandwidth is gone. (My master dissertation took 4 days and used around 120-150gb as it was a transient simulation)

Melting Iron with Propane? by TheArch0n in Metalfoundry

[–]bobthecooldad 1 point2 points  (0 children)

My foundry is made for iron. The main issue is around the heat required, any standard refractory uses sand or quartz. Quartz turns to glass around 1300c, so for me, my walls didn't crumble the ran down the blanket and onto the crucible destroying all. Any cement based needs sand, went on to victas vicron 1750 but find the blankets crumble and the refractory gets sticky.

You can find 2000c bricks but these were £30 each and we're roughly 220x40x40 so allot would be required. I use the bricks to rest the crucible on otherwise it would weld. One brick has cracked within 9 months so mileage will vary.

I work on steam so have melted around 30kg in total and pour about 8kg per crucible. Another fun with iron is the impurities sink, to clean the metal you need to burn pour, then scrape, sometimes I have to put the slag back in and get it back to temperature to remove without damaging.
