    What have you been doing today?

    I have spent the last few weeks making an angled non-slip jigsaw table for a friend so that she doesn't have to bend over a flat table to do them. Today I got to try a mock-up of the table to see if the pieces would slide off. I borrowed a jigsaw from my friend and put the table at a 45 degree...

    Painting aluminum castings problems and questions.

    If you are going to take the engine apart to remove the paint perhaps you could grit blast it? I don't mean the sort of grit used on rusty metal, but some sort of plastic material. It might even leave a surface that will take paint better.

    Aladdin's cave of machines to dispose of - help needed

    Hi David, sorry about the loss of your brother in law. It would help if you could tell us what part of the country the machines are located. There might be someone reading this who could spare the time to see them. Good luck, Lee

    My Flat Head Hit Miss Engine

    A very nice build. There's something hypnotic about a hit and miss engine running.

    timo_gross. I think that's the way John described the process, he does some very nice iron work.

    Question about lost PLA casting

    John Woodward of JW Engineering here in Cornwall invited me to watch a pour. I think it was about 25kg or more of iron with several kg of glass. He was advised to add the glass by an old foundry worker. This is his web site.

    Question about lost PLA casting

    I was invited to watch a pour of cast iron where glass scrap was used to fuse to the dross and make the pour cleaner. I dont know about brass.

    Cutting gaskets with K40-style laser?

    I think that Myfordboy used a laser to cut gaskets. It might be worth a look on youtube.

    Question about lost PLA casting

    I use a resin printer for pieces that need fine detail, and an fdm printer for pieces that need strength. A piece can be printed on the print bed, but that might make it very difficult to remove after printing. The first several layers of a print are exposed to uv light for about 40 seconds or...

    Question about lost PLA casting

    I watched several videos recently by Ingot Joe. He printed in PLA and used an oil bound sand. He left the 3D print in the sand and used a blowtorch to melt out the PLA before pouring. It seemed to work. He also tried pouring molten metal directly on to the PLA, and as he says himself, "it did...

    What have you been doing today?

    For the first time in years I didn't have to get up during the night to use the loo. I think it might be because I decided not to have bread with my meal last night, thats the first time I've gone without bread with a meal for many years. I will stay off bread for a while to see what occurs. I...

    Total new-comer to CAD. Which programme to choose.

    A trick to try with Design Spark when you want to mirror a part is this. Save the part as an STL, import it into a slicer programme, use the slicer to flip the STL and save the file as an STL again, import it into DS and it will try its best to convert it into a solid for you. Success not...

    Total new-comer to CAD. Which programme to choose.

    I have FreeCAD installed and find it fairly easy to use. It does have a confusing menu system, and there are features missing, like being able to add draft to text, but even my preferred cad programme, Designspark 5, sometimes fails to do that. DS5 is by far the easiest cad programme I've used...

    Total new-comer to CAD. Which programme to choose.

    I only discovered last night that DS5 will calculate the area and weight of a part if you tell it what material you are going to use. Vary handy if you are casting the part.

    What have you been doing today?

    Today I removed the fibreglass body from my A7. I started to build the body nearly 25 years ago. I had to struggle to undo some of the nuts and bolts, some I couldn't undo and had to chisel into the bodywork to release them. Most of the body parts are now sitting on my patio waiting for a...

    Total new-comer to CAD. Which programme to choose.

    I use Design Spark Mechanical for my CAD work. It has a few limitations, like, no mirror function and poor text design. I use version 5 which will import a STEP file, reluctantly! The newest version, 6, won't import STEP files so I switched back to 5. It exports few file formats, but will export...

    What have you been doing today?

    Last night I had a thought. If I want more room in my garage/workshop, then I would have to reinstall a steel shelf unit I removed a few months ago to give me more room, it didn't. So, have a big move around of tool boxes to clear the wooden shelf unit. Take all the Austin Seven gubbins out of...

    Home foundry blunder

    I found this on GOV.UK At Budget 2020, the government therefore announced that it would remove the entitlement to use red diesel and rebated biodiesel from most sectors from April 2022 to help meet its climate change and air quality targets. The tax changes will ensure that most users of red...
