Metal repairs using epoxy metal and other resin based products
Manxmodder:
Thanks Steve, another thought on increasing the strength could be to include some super fine glass fibre strand all chopped up and added to the metal powder.
Another resin I use for purposes other than what the manufacturer intended is Masonmate,a non styrene polyester paste intended for fixing steel anchor bolts into masonry and repairing cracks.
It also forms a very robust compound when set and can be shaped filed etc.....OZ

Hi All
I have used a combo of epoxy mixed with steel wool for a down and dirty fix of a stripped screw hole. It has worked well the few time I have done it, however I would not depend on it in critical applications. Works quite well for wood screws....think furniture!

Hi Manx
I have used home made fillers very successfully for may years now, using super epoxy, a colourless adhesive. The fillers I have used are aluminium, brass, copper and cast iron in the form of fine metal filings. The best results have been on iron and aluminium. I don't specially make filings, but carefully clean down my vice after filing metals, and keep the filings in small labeled jars. I mix the filings with the epoxy 2 part adhesive to form a stiff paste, then apply to the workpiece using a knife. When cured it responds well to various cutting and finishing processes.
Cheers David

Cheers David. This time I used some iron swarf/chips produced whilst turning a job in the lathe. I gathered them into a small earthenware bowl and used the ball end of a ball pein hammer to mill them to a fine powder. I do also have about a kilo of commercially bought iron powder and two 25 kilo drums of fine brass powder some of which have been used with araldite epoxy in the past.
Just out of interest,I recall reading that foundry men of yesteryear used to make filler cements of ground up iron filings and sal ammoniac.....OZ.

Hey Burt, I would never have thought of steel wool. That sounds another interesting combination to have a play with. Cheers for that :thumbup: , I'll give it a go......OZ.
