I know what your thinking - boring boring boring! BUT building a cartie when using any tools, including power tools can be hazardous to your health!
If reading this page is as boring as it gets then its done is job, because I have spent too many a boring afternoon or evening in accident and emergency waiting to be stitched up or have alien material removed from my eyes (when a lot younger and not so wiser). And time spent in A&E is an afternoon not doing work on what you wanted to do!!
I have had arc eye - and it is sore - take it from me you don't want to experience it - its like having a large lump of sharp sand in the middle of your eye.
Ask someone who has had it, what its like - don't try it!
Get the correct welding protecion for the welding you are doing - oxy googles just wont be sufficient protection for mig and arc welding. Reactive welding masks can be a bonus when learning to weld, they save having to continuously having to lift the mask up and down. Not cheap, but can help enormously.
A full face mask not only protects the eyes, but the rest of the face especially if a disc breaks up. Now this is scary if you get a cutting disc that breaks up - fortunately any time this has happened, I have had a full face mask or a good set of googles.If using goggles rather than a full face shield get some good googles suitable for the job. A reputable supplier can advise - not all are suitable for protection against impact. Grinding shrapnel and dust travels at speed and not only is it sharp it can be hot - not very good for the eyes.
When working with fibreglass:
It is definitely recommended when working with fibreglass to have the eyes protected at all times:
When mixing resin and working with resin, it is very easy to get splash back. A drop of resin, catalyst, or both can painful and harmful. It should be noted that the best protection will also include a mask to protect you from the fumes.
When cutting and sanding fibreglass, wearing goggle with a mask, will protect you from the very fine particles. Remember what you are cutting and what harm it can do.
Safety eyeware - honestly, it is not worth not using it!
Use the right gloves for the job you are doing and ensure the gloves go over your sleeves. This stops any nasties getting caught between skin and cuffs.
Use good sturdy work gloves, when grinding, handling sheet steel.
Welding gauntlets when welding, protects from heat and UV exposure (mig welding).
It is worth buying a box of disposable gloves, there are various types to suit those who suffer from allergic reactions to certain materials i.e latex. These should be good fitting so try and buy the relevant size, if they come in sizes. Ideal when working with any solvents or resins or oily components.
Scars and burns really aren't a good bragging right. Oil stained or paint covered hands don't usually look to good when going out either, either. Gloves might be awkward at first, but you will get used to working with them in no time.
Ears - if doing any continuous grinding etc. invest in a set of ear defenders or ear plugs. Also stops you hearing the wife (or neighbours) complaining.
Steel toe capped boots will stop your toes getting mangled. Always wear trousers/overalls over the boots. A stray welding spatter getting down your boots is not nice!
If working with fumes or dust, wear a mask, once its in your lungs it is not coming out.
The rest of you.
A good set of overalls will not only keep the underclothes from getting too manky, but also act as a barrier. When welding and grinding heavy duty cotton type are more suited than the nylon types and will not catch fire as easily and also will not melt.
The above are only my guidelines and they are in no way definitive. My advice is don't take my word for it, always ask an expert to ensure that you are buying/using the correct equipment for the job. There are loads of websites to help you out.
Have fun, keep safe and stay out of A&E.
