I’ve always made a point of recommending these! I don’t know how I would get things done these days without solid, right-angled steel blocks .. to use as guides for construction, for gluing against or weighting down. I’ve noticed though that my enthusiasm has varied between ‘absolutely essential’ to ‘very useful’. The reason for my occasional reticence is that up to now I haven’t been able to recommend a reliable source .. but now I can! I’ve just received these .. seven in all .. which I ordered from https://www.metalmaniauk.com/ because I’ve always wanted to use them on my courses.
In the past I had assumed that the custom cutting charge would be too high but these seven cost me all inclusive £33.10. I chose the ‘Bright Flat Mild Steel’ which has the essential square ‘sharp’ edges; and the bar type ‘1 x 3/4’ inches, which I felt was the smallest limit before the blocks lose the necessary weight; and I decided that a 15cm length would be fine for most tasks. Here is the specific link to the product
MetalMania do not have a minimum order so one could buy just one of course. This would cost £3.80 for 15cm, but postage within the UK seems to be fixed at £6.50 up to a few kilos so it would make more sense buying two or three.
A recap on why they’re so useful
I’ve written about them many times both here and in my book. The most useful application is when gluing two pieces on edge, applying glue to one and then positioning the two pieces together against the metal block so that one can be sure of getting a clean and straight edge.
It is especially important having this firm ‘stop’ when using superglue because it has to be right first time and .. more importantly .. it doesn’t matter if superglue squeezes out onto the metal because it won’t stick to it strongly. The piece just needs to be ‘popped’ off. You have to remember to scape the metal surface clean with a scalpel occasionally because it can build up. If you have two blocks, as below, you can construct perfect corners!
Blocks of any kind with enough length are also invaluable when trying to layer thin strips on top of each other i.e. for these decorative mouldings.
They can also be useful for holding elements in place while gluing, as below where I’ve taped a curving piece of styrene between them to hold it in that position while I brush plastic solvent into the join. The same can be done with thin superglue.
Finally, and by the way .. I feel it’s worth noting that dealing with MetalMania was a smooth experience with a couple of pleasant curiosities! In the first place their website is different from what I’m used to when trying to get hold of heavy-duty industrial materials .. bright, friendly and simple to understand. Delivery was trackable and came within 4 days using Parcel2Go .. not the usual kind of breathless courier at the door but three teenage girls! I didn’t find out why because they didn’t seem to want to be quizzed about it. On the MetalMania website they state under the heading ‘Animal Policy’ that ‘It is this companies policy NOT to supply any organisation or individual involved in animal experimentation of any kind’. Currently on the website is also a condolence message for those affected by the attacks in Spain which is accompanied by this photo. I don’t know what to make of it .. but it’s really got me thinking!
