When I was a mechanic I loved my power probe and then my power probe 3(with voltmeter) , however now I do upholstery I've only used it once in the last 5 years.Power probes do make light work of basic fault finding however with modern computer controlled cars you do need to be carefull you don't let the smoke out of stuff.

Thank you, just ordered the book after your recommendations.

My second hand foam saw made some unusaul noises and sparks were coming out the back last year.The internal capacitor had blown, easy and cheap to repair myself.Heres where I got the spares from for those of you in the uk.You need to search by tool model number.

Bottom ones look like metal shears.

Both, in the past we reused it however we have now found a supplier of something similar that works.When I'm back at work on friday I'll try to find the name of the supplier.

Thanks for that, I'll try it neat time.
Always trying to improve my work.
Normally I would use 6mm or 10mm scrim on the center section of a seat and 3mm on the sides of the faces however they never look as smooth or tight as the pics I see others post on instagram should I move up to using 6mm all over?

I did some headrests the other day with perimeter sewn 3mm scrim and ended up having problems with the foam rucking/creasing up and causing lumps in the headrest.

I've just bought a jiffy j2 but as I haven't used steamer before I'm a little wary of causing damage and knowing how to use it sucessfully.

What glue do you use in the hot glue gun Chris as the ones I've got don't seem to stick well?

I also use calico for backing on fluted sections.Do you glue yours or perimeter sew.

I was trained to glue the material on however recently I have been sewing on.With it sewn on it does seem to feel nicer.I stil glue if its a quick, cheap job.I was using some fabric last week which needed glueing as it moved so much when trying to sew the foam on.
How does everyone get on with sewing listing tubes onto sewn down foamed material, when the tube is attached across the center of a panel? I've found the top and bottom move around a lot when sewing it on.

I just had a friend make two cnc routed templates for diamonds in 2mm acrylic, cost will be a seat repair.Try getting a sign making shop to make them.

I've got the full set.Its surprising the uses for them, not only french seams.I make a lot of tool rolls and the 1/4 inch makes a nice folded seam or you can use on a single stitch machine to make 1/4 parallel lines on a seat or door panel.

We call it ruching at our workplace.Horrible trying to get creases in your work.
