I have a few blue velvets tnat need trimming.

I'm worried that the vibrations from sawing with a hacksaw could damage the pot.

Is there a better method, or are my worries unfounded?

I use the Dremel with the cutting wheels....but be careful since the pot can get hot with this method.

Clamping the shaft in a vise while cutting it should help dampen the vibrations

EDIT: That's what I usually do.

I use a dremel with the cuttng disc and a damp towel to cool the shaft down and protect the actual pot casing from the metal scraps.

A hacksaw is fine, you wont damage it as long as you take it easy enough
I've done heaps of blue velvets with a hacksaw

Next question, how many attachments do you think I need for general DIY casework?



Along with the recommendations for cut-off wheels, I highly recommend getting the set of tungsten carbide cutters (you can normally buy a set for about 10-20 dollars on ebay) with the multipurpose cutting kit.

As for the actual dremel, I suggest you get the Variable Speed MultiPro Rotary Tool kit (one with the most accessories). Its much cheaper to get the kit than to get some of those individual accessories separately. I've never used the 400 Series XPR Rotary Tool yet, but I've heard some good things about them (maybe a good investment in the future).

, I'm looking to get into some DIY projects and have been researching dremels. Any advice on a good place to buy one? (Home depot & Crappy Tire vs. ebay, etc). For some purchases I prefer going through a local dealer vs. online, any advice?

Lowes carries dremels and I think Home depot also.

You can always find a cheaper kit on ebay, but it really depends on the seller if they do have good deals. I've even noticed some local hardware shops carry dremel kits.

Just make sure you look for a kit that has many accessories as purchasing them later on will cost you a pretty penny

Remember, always get the variable speed model, don't get the single speed dremel mainly because many accessories can not be used with the single speed dremel tool.

I have a Dremel 400 XPR and I am very happy with it. I don't know much about the other models. I got it at Home Depot when they had a 25% off sale at Christmas time last year.

The standard cutting wheel that came with the kit will cut the pot shaft in about 2 seconds. The pot I cut is a little noisy when I turn it; I do not know if that is related to my cutting job or not. The cut did not seem to stress the pot in any way because it cut like butter. I also ground down the tab so it would mount flush to the panel. That took a little longer.

Looked at that 400 XPR model at home depot last night, VERY nice. They've come a long way with accessories since the single speed version my dad had back in the 80's...Does anyone find that flexible shaft attachment useful? Thinking of pulling the trigger on the 70 piece kit
