Making a Valchromat Picture Frame

Making a Valchromat Picture Frame


In this video I’m going to use some more
scrap valchromat to make a simple picture frame for this amazing drawing I’ve been
sent by Sirus. To start with I cut the valchromat into four
length at 24mm wide pieces. I then set up my router table to create the
rebate and turn the pieces into picture frame moulding. I’m going to router off 7mm in, and 14mm
high, and I’m doing this in small section at a time. I’m keeping the height of my bit the same
and moving the router table fence away from the router bit – to widen the rebate. The wrap around extraction port on my palm
router is doing a very good job at extracting all the red dust. I was planning to 3D print something for the
top extraction to fit within the c-beam but I’m not sure I need it. Ok I’ve worked out that if I keep this bit
of acrylic as high as it is, that’s 194, I only need to cut it down 261 and this drawing
should sit quite nicely in the centre with an even gap around. 266. I’m now going to cut the mitres, making
sure opposite pieces are the same lengths. I measure up against the Perspex, and after
cutting I use the first piece as a reference to cut the second. The final mitre cut for each pair is done
by holding the pieces, one on top of the other, making sure the mitre furthest away from the
blade is flat, and proceeding to cut. You may notice that after I make my plunge,
I let go of the switch to allow the blade to come to a stand-still. I do this to make sure I don’t cut on the
lift, which is possible with mitre chop saws. This chop saw is a real monster. It is probably as old or even older than my
YouTube channel and again doesn’t have soft start of breaking. I also rebuilt the base. I really should think about fitting a clamping
attachment to it, if I intend to carry on using it. I put all the pieces on a flat bit of MDF
and then check the frame is square by measuring between either corner. This is my new workshop pet. It’s a v-nail-apeed. It’s highly dangerous and only a trained
person can keep one – like myself. It seems to like me. I cut the offcuts from the moulding into smaller
sections. I’m going to need 8 to help me clamp the
frame together. Note how I use the back end of a push stick
to keep my fingers away from the blade. I’m using a method of wrapping and tying
some thick string around the frame, and placing the offcut of the frame itself between the
frame and string, using two for either side. I then push the pieces to the edge and this
tensions the string and applies clamping pressure to the corners. It’s a really effective way of clamping
picture frames. If you weren’t sure about the tension that
this simple clamping method can create, just listen to that. I tried to hammer a short v-nail into the
edge but the velchromat is really dense and doesn’t penetrate as nicely as I’d like. Possibly using a micro drill bit and some
veneer nails would have been a better option. People often think this stuff is like MDF,
it’s really not like MDF. It’s very different. See that’s actually opened it up a little
bit. Look at that joint, you can barely see it. I’ve learnt a few other tricks with string,
one in particular that will be really good for the CNC machine but also in terms of levelling
something much larger then this. If you’re making a really big frame and you
want to make sure it’s perfectly flat, you simply tape a bit of string from one corner
to the other and again on the opposite corners and you look and where the line intersects. And if they’re just touching it means that
the frame is flat. If one is a bit higher than the other or pushing
too tight, you know you frame is twisting. It’s amazing what you can do with just a piece
of string. After the glue sets a little I give everything a sand. I
just oiled the frame, and what I did was, as it was drying I would sand the edge a little
bit to flatten it out. Surprisingly it’s worked. You wouldn’t be able to do that with MDF. The alternative is to use a bit of polyurethane
varnish. That would have been better to be honest. Ok that’s not too bad. That’s Sirus’s drawing that he’s sent to me
in a frame I’ve made from Valchromate with a cork backing board. If you’d like to send me a drawing, and
Sirus has set the bar very high with his attempt, drop me an email via the about section of
my channel page and I’ll send you the address. Thanks again for watching.

    I think that the frame in this state 4:50 is great looking. String and all!. Interesting material.

    Good trick with the string.

    Looks amazing, frames not bad either ;p. Never seen velcromat before, edam skin impregnated mdf?
    This channe vid didn't show in my sub feed so had to unsub/sub. I got the heads up from your instagram post. JFYI
