I have a resin cast bridge abuttment that is about 1/16 to 1/8th inch too tall… aaaarrggg! What is the best way to cut this type material that I’ve never worked with? My hobby saw? Dremell tool with cut off disc? Any other tool?
Thanks for your suggestions and tips!

I would use a razor/hobby saw, though it might be tough to remove such a narrow piece.
Hobby saw! dremell will melt it and leave an rough edge.

Removing that little bitty bit is what concerns me the most, Simon. If I’m going to cut anything I’d much rather it be like a 1/2 inch at least. Thanks for the suggestion.

Ok Jim, that’s what I was wondering about. Hmmmmm… I wonder if I could use the dremell with a sanding drum and gently sand it away. I thought about sawing off at least a quarter inch but that just leaves me with having to put something under the bridge itself to bring it back up to level.
Oh well, I’ll figure it out. Thanks!

Take a sheet of sandpaer, say 120 grit and tape it to a FLAT surface, piece of glass works great, and hold the pice in your hand and rub the piece on the sand paper applying pressure evenly. Check frequently, every 10 strokes or so for progress and evenness. Slow progress but it works for me.

HI,
I do not cut the resin casting, as a matter of fact I keep them in a box. I make rubber molds using the resin casting as a master (that way I only have to buy one of each) and then use Plaster of Paris to make many casting that are easy to cut to size and very easy to stain.

I like this idea. I have soooooo little to take off, probably just a hair over 1/16th inch… this just might do the trick. Thanks Jim, I’ll give it a try in the morning.

If you have access to a power miter saw, add a masonite blade backwards, and trim the casting. MUCH faster than sanding!
Thanks Ray. I don’t have one but I’ll ask some friends that might.
I like power tools… [:)]

Stationary power sander or belt sander secured upside down in a vise. The key is a flat surface. A sandpaper sheet on a block of wood works very well too (especially for a single piece) and is more controllable.
Go very slowly and gently to avoid overheating the material. Hold tightly and watch your fingers! They can be thinned with a sander too.
Good luck.
If you’re going to sand resin, be sure an protect your lungs from the dust with a breathing mask and a high speed air fan to carry the dust away.
I’d either sand it or grind it. Chuck it in a small vise and then come up with a Dremel tool on the end. When I got it down to finite proportions I’d tape some 400-600 grit sandpaper to a sheet of glass and polish it to final proportions and specifications.
Is it floating in the senery or is it sittingh on the substructure? I’d just remove the senery than try to cut that little amount. Senery is eazy to fix.
