V Groooooooves

Postby Dan » Fri Jul 30, 2010 10:29 pm

I had the Valiani and I used to do alot of Vgroves with my Fletcher 6100. With the Valiani when doing suedes I have to work for a long time after the cut to get rid of the roller marks on the suede board. Any help out there as to have to do?

I don't think there is much you can do to stop any cmc that uses a roller on the cutter foot crushing a suede finish. The normal procedure when cutting any easily marked finish is to cut face down - you obviously cant do this when cutting V grooves.

Off the top of my head couple of suggestions of ways that might work: use a removable masking tape to protect the finish - use a cover sheet of thin paper - adjusting your settings to allow for the extra cut depth.

I would imagine that both suggestions might present other challenges - but would be worth experimenting.

blowing the suede finish with a air gun can just lift the nap and restore the finish.

You could try reducing the head downward pressure, so that the roller does not flatten the nap too much.

MarkW's suggestions are good. I have used the 'cover sheet' method (500 micron) with some success.

I will give those a try before I get a job in that needs it. The air gun to bring the suede back is good I had been useing a tooth brush and it takes so long to work a large board with that.

use a piece of offcut suede board and rub them face to face to remove the marks. its a very quick solution.
(wizards dont have a wheel but we can get the same problem with debris getting beneath the cutting head footblock). you can see what i mean about the footblock in this youtube video



On the bright side: Suede is one of the few boards that really lends itself to debossing nicely, whatever CMC you have. V-grooves can be a bit too "in your face" on suede, whilst debossing can be a bit too subdued on plain boards. Worth investing in a debossing tool if you are going to be working with a lot of suedes.

I have a Valiani and have had success masking V Grooves (for colouring) with masking film - never tried on suedette board though.

Tape is a bit time consuming even if less extravagent, a thin board is more extravagent and a thin paper would just get dragged all over the place.
